Accounts Receivable (AR) is the money a business is owed by its customers for goods or services delivered but not yet paid for. It sits as a current asset on the balance sheet and represents future cash inflow.
Accrual accounting is the method that recognizes revenue when it is earned and expenses when they are incurred, regardless of when cash actually moves. It is required under GAAP and IFRS and is the foundation for AR balances, DSO, and allowance calculations.
ACH (Automated Clearing House) is the US electronic funds-transfer network that batches and clears bank-to-bank credit and debit payments. It is the dominant rail for B2B invoice settlement in the US, processing tens of trillions of dollars annually with growing B2B adoption replacing paper checks.
Agentic AI is software that combines large language model reasoning with the ability to act autonomously on behalf of a user. In finance, agentic AI executes workflows (cash application, collections calls, deduction investigation) rather than just generating recommendations for human action.
AI Governance is the framework of policies, processes, controls, and accountability structures that ensures AI systems are deployed safely, ethically, legally, and reliably across their full lifecycle. In finance, it covers how AI is used in credit, cash application, disputes, and forecasting, with documented oversight, monitoring, and audit trails.
A hallucination is when an AI model, typically a large language model, generates output that sounds fluent and confident but is factually incorrect, fabricated, or unverifiable. In finance, a hallucinated invoice number, customer name, or euro amount can post cash to the wrong account, extend credit to the wrong entity, or pollute the audit trail.
Allowance for Doubtful Accounts (ADA) is a contra-asset on the balance sheet representing management's estimate of receivables that will not be collected. It reduces gross accounts receivable to a net realisable value and is the accounting mechanism for matching expected bad debt expense to the revenue period.
Anomaly detection is a set of machine learning techniques for identifying observations that deviate significantly from expected patterns in data, used in AR to catch fraud, duplicate invoices, unusual deductions, and forecast variance.
ANSI X12 is the dominant North American EDI standard, governing how trading partners structure and exchange business documents like invoices, purchase orders, and remittance advice across more than 300 standardised transaction sets.
AR Aging (or the AR Aging Report) groups open invoices by how many days they are past due, typically in buckets of current, 1-30 days, 31-60, 61-90, and 90+. It is the standard tool for spotting collection risk and prioritising follow-up.
An audit trail is a chronological, tamper-evident record of system activities that documents who did what, when, and to which record across financial transactions and the decisions that shaped them.
Auto Cash Application is the automated matching of incoming customer payments to open invoices and posting of cash to the general ledger without manual analyst intervention. It replaces the time-intensive manual cash application process with software that captures remittance, matches payments, and resolves variances at machine speed.
Average Days Delinquent (ADD) is the average number of days invoices are paid past their due date, calculated as Days Sales Outstanding minus Best Possible DSO. It isolates the portion of receivables drift caused by late payment behaviour, making it a cleaner measure of collections team performance than raw DSO.
BACS (Bankers Automated Clearing Services) is the UK's primary batch electronic payment system, operated by Pay.UK. It moves money on a three-day cycle via two products: Direct Credit for outbound bulk payments (payroll, supplier runs, refunds) and Direct Debit for pulling scheduled collections from customer accounts under a signed mandate.
Bad Debt is the portion of accounts receivable a company has concluded will not be collected and has written off against earnings. It represents the irreversible loss from credit sales and is the final stage of the AR lifecycle for invoices that did not convert to cash.
Bad Debt Ratio is the percentage of net sales or accounts receivable written off as uncollectible during a period. It is the realised credit-loss rate that CFOs use to judge whether credit policy, collections coverage, and risk scoring are actually working.
BAI2 is a flat-file bank reporting format, defined by the Bank Administration Institute, that banks use to transmit prior-day balances, transaction detail, and lockbox remittance from the bank to a corporate treasury or AR system.
Bank Reconciliation is the process of matching transactions on a company's bank statement to its internal accounting ledger to confirm that recorded cash equals actual cash. It is the foundational control between bank-side reality and accounting-system records, and it is one of the most labour-intensive monthly close tasks at scale.
Best Possible DSO (BPDSO) is the theoretical minimum Days Sales Outstanding a business could achieve if every current (not yet past due) receivable were collected the moment it became due, calculated as current AR divided by total credit sales multiplied by days in the period.
A trade-promotion settlement method where the retailer pays the full invoice upfront, then bills the CPG supplier back for the agreed promotional allowance after the promo period ends, based on scan data showing units actually sold.
A billing cycle is the recurring period at which a supplier issues invoices to a customer. It sets the rhythm of revenue, cash flow, and AR workload, and ranges from per-transaction to annual depending on the business model.
CAMT.053 (Cash Management, ISO 20022) is the standardized XML bank statement format that reports an account's closing balance and full transaction detail for a given period. It succeeds older formats like MT940 in most European markets, carrying richer structured remittance and reference data that AR teams use to automate cash application and reconciliation.
Cash Application is the accounts receivable process of matching incoming customer payments to the open invoices they are meant to pay, then posting the result to the general ledger. It closes the loop between bank statement and ERP.
Cash Conversion Cycle (CCC) measures the time in days between paying suppliers for inputs and collecting cash from customers for the goods or services produced. It is the working capital metric that combines AR, inventory, and AP into one number.
Cash Flow Forecasting is the process of predicting cash inflows and outflows over a forward time horizon, typically 13 weeks for treasury operations or 12 to 18 months for strategic planning. It is the primary input to liquidity management.
Cash pooling is a treasury technique that consolidates the cash balances of multiple subsidiaries or accounts within a corporate group into a single concentrated position, allowing the group to optimise interest, fund operations internally, and reduce reliance on external borrowing.
Cash Position is the total amount of cash and cash equivalents a business has available at a specific point in time, across all bank accounts and short-term investments. It is the foundational daily measurement that treasury teams use to manage liquidity, fund operations, and make investment decisions.
A cash sweep is the automated transfer of funds between bank accounts based on rules, typically moving end-of-day excess balances up to a master concentration account or funding shortfalls down to operating accounts. It is the mechanism that operationalises cash pooling and Zero Balance Account structures.
A Chargeback is a customer-initiated reduction of an invoice payment, typically applied by large retailers or enterprise buyers for alleged compliance failures, damage, return shortfalls, or contract disputes. Chargebacks differ from agreed deductions in that they are unilateral and often require investigation to determine validity.
A Chart of Accounts is the organized, hierarchical list of every account a business uses in its General Ledger to classify financial transactions for reporting, consolidation, and compliance.
A collection agency is a third-party firm that pursues overdue B2B receivables on behalf of a creditor, typically working on contingency and keeping 25 to 50 percent of whatever it recovers.
Collections Effectiveness Index (CEI) measures the percentage of overdue accounts receivable a company actually collects within a given period. It is the standard quality metric for collections operations, complementing DSO with a measure of how effectively the team is working its overdue book.
Commercial Paper (CP) is a short-term, unsecured promissory note issued by large investment-grade corporations and financial institutions to fund working capital, payroll, receivables, and other short-term liabilities, typically with maturities of 1 to 270 days.
A Compliance Deduction is a penalty a retailer deducts from a supplier's payment for violating supply chain compliance rules (shipping accuracy, labeling, EDI, on-time delivery, fill rate). Walmart's OTIF programme charges 3 percent of cost of goods sold; Target's OTFR programme charges 5 percent. Compliance deductions are typically the largest single category of retailer-driven AR leakage in CPG.
A temporary block on a customer's new orders or shipments, triggered when they breach their credit limit, fall significantly past due, or show other credit risk signals. The hold stays in place until the underlying issue is resolved through payment, a payment plan, or an approved exception.
Credit insurance, also called trade credit insurance, is an insurance product that protects a business against the risk of non-payment by its trade debtors due to insolvency, prolonged default, or political risk. The insurer underwrites each customer, sets a per-buyer credit limit, and pays out a percentage (typically 80-95%) of any defaulted receivable in exchange for a premium of roughly 0.1% to 0.4% of insured turnover.
A Credit Limit is the maximum outstanding credit a seller will extend to a single customer before requiring payment or blocking new orders. It is the primary operational control on customer credit risk and the trigger point for credit hold workflows when exceeded.
A Credit Memo is a document issued by a seller to a buyer that reduces an outstanding invoice or applies as a credit toward future purchases. It is the formal mechanism for adjusting accounts receivable when a customer is owed an amount because of returns, pricing corrections, promotional rebates, or dispute resolutions.
A credit policy is the documented set of rules governing how a company extends, limits, monitors, and collects customer credit, covering application requirements, scoring, limits, terms, holds, dunning cadence, and write-off authority.
Credit Risk is the probability that a customer fails to pay an outstanding receivable, leading to bad debt write-off. Managing credit risk requires upfront credit assessment, ongoing monitoring of customer payment behaviour, and limit enforcement to keep AR concentration within tolerable bounds.
Current Ratio measures a company's ability to cover short-term liabilities with short-term assets, calculated as Current Assets divided by Current Liabilities. It is the most inclusive liquidity ratio because it counts every current asset, including inventory and prepaid expenses, against every obligation due within twelve months.
DATEV is the accounting, tax, and payroll software ecosystem used by most German tax advisors (Steuerberater) and many German SMEs, with no direct US equivalent. A DATEV interface (DATEV-Schnittstelle) is the export format, API, or connector that lets another finance system exchange bookkeeping data with DATEV for posting, reconciliation, and tax filing.
Days Beyond Terms (DBT) is the average number of days a customer pays after the agreed invoice due date. Unlike DSO which includes the negotiated payment period, DBT isolates the overdue portion of the payment cycle, giving a cleaner view of customer payment discipline.
Days Deductions Outstanding (DDO) is the average number of days open deductions remain unresolved on the AR ledger. It is the deductions-specific counterpart to DSO and a direct measure of deduction resolution efficiency, with high DDO indicating either capacity constraints or process bottlenecks in deduction management.
Days Inventory Outstanding (DIO) is the average number of days a company holds inventory before selling it. It is the inventory component of the Cash Conversion Cycle and a key indicator of supply chain and demand planning efficiency.
Days Payable Outstanding (DPO) is the average number of days a company takes to pay its suppliers after receiving an invoice. It is the payables counterpart to DSO and a key lever in the cash conversion cycle.
Days Sales Outstanding (DSO) is the average number of days it takes a company to collect payment after a sale. It is the single most-cited metric in accounts receivable.
A debit memo is a document issued by a seller that increases the amount a customer owes on an existing invoice or account, typically to correct an undercharge, add fees, or recover costs that were missed at original billing.
Deduction Management is the AR process of capturing, validating, and resolving customer short-pays. It covers the workflow from initial deduction notification through investigation, dispute filing, and ultimate write-off or recovery.
A Deep Neural Network (DNN) is a neural network with multiple hidden layers between its input and output, enabling it to learn hierarchical representations of complex data such as images, text, payment sequences and remittance documents.
A delinquency bucket is a band of days past due used to group overdue invoices for analysis, reporting, provisioning, and collection workflow triggers. Standard B2B buckets are Current, 1-30, 31-60, 61-90, 91-120, 121-180, and 180+ days past due.
A Demand Letter is a formal written notice demanding payment of an overdue debt by a specific deadline. It is typically the final step in internal collections before referring the account to a third-party collection agency or legal action, and it serves as both a final attempt at amicable resolution and a documented record for subsequent escalation.
Direct Debit is a pull-based payment method where the customer signs a mandate authorising the supplier to collect funds directly from their bank account on agreed dates. The supplier initiates each collection, making cash flow predictable but requiring strict mandate management, pre-notification, and handling of returns under scheme rules such as SEPA, BACS, and ACH Debit.
Direct Method Cash Flow Forecasting projects actual cash receipts and disbursements by date over a short-term horizon (typically 13 weeks). It is built bottom-up from AR collections, AP payments, payroll, and other cash flows, and is the treasury standard for daily liquidity management and short-term cash positioning.
Dispute Management is the AR process of investigating, resolving, and recovering value from customer-initiated billing disputes. It covers short payments, deductions, pricing claims, and contract interpretation issues that prevent invoices from converting to cash.
Dunning is the structured process of contacting customers to remind them about overdue invoices and request payment. It is the core operational discipline of B2B collections and the most-used touchpoint between AR teams and customers.
EDI (Electronic Data Interchange) is the computer-to-computer exchange of structured business documents (orders, invoices, remittances) in standard formats between trading partners. It is the foundational technology for B2B transaction automation and the mechanism that enables straight-through processing for cash application, deductions, and order-to-cash workflows.
EDI 812 is the ANSI X12 Credit/Debit Adjustment transaction set that large retailers use to notify suppliers of deductions, chargebacks, billbacks, and pricing adjustments with line-level detail and reason codes.
EDI 820 (Payment Order / Remittance Advice) is the ANSI X12 EDI transaction set that transmits structured remittance detail from payer to payee for automated cash application. It carries invoice references, payment amounts, adjustments, and dispute codes in a machine-readable format that drives high cash application straight-through processing rates.
E-invoicing is the exchange of structured, machine-readable invoice data between supplier and buyer in a digitally native format, transmitted through a certified network or government clearance platform rather than as a PDF or paper document.
EFT (Electronic Funds Transfer) is the umbrella legal and regulatory term for any electronic movement of funds between accounts, covering ACH, wire transfer, credit card, RTP, FedNow, and other electronic payment rails. In the US it is governed by Regulation E. EFT is conceptually broader than any single payment rail and is used in legal, regulatory, and broad strategic contexts rather than for specific operational decisions.
Embeddings are numerical vector representations of text, images or audio that capture semantic meaning, so that items with similar meaning sit close together in mathematical space and can be searched, compared and classified by what they mean rather than the exact words they use.
An escalation matrix is a documented framework that defines who gets involved when collections, disputes, or credit issues cross specified thresholds. It specifies the actor, trigger, action, and timeline at each level so accounts move predictably from a friendly reminder through to legal action or write-off.
Explainable AI (XAI) is a set of techniques and design principles that make AI model decisions understandable to humans, answering the question why a model produced a given output. In finance, it is essential for regulatory compliance, audit defensibility, user trust, and effective debugging of AI-native and agentic systems.
Fine-tuning is the process of further training a pre-trained foundation model on a curated dataset so it adapts its behaviour, style, or task performance to a specific domain. In finance, it is one of three main ways (alongside RAG and prompt engineering) to customise large language models for AR and O2C workflows.
A foreign exchange rate is the price at which one currency can be exchanged for another, expressed as a ratio between two ISO 4217 currency codes (for example EUR/USD 1.0850). FX rates drive how multinational AR teams invoice, record, revalue, and settle receivables denominated in currencies other than the functional currency.
A foundation model is a large AI model pre-trained on broad data at scale that can be adapted to many downstream tasks, replacing the older paradigm of building one narrow model per problem.
Free Cash Flow (FCF) is the cash a business generates from its operations after accounting for the capital expenditures needed to maintain or expand its asset base. It is the headline measure of a company's ability to fund growth, pay dividends, reduce debt, or return capital to shareholders without external financing.
Freight audit is the process of reviewing freight invoices and shipping charges against contracted rates, bills of lading, and actual services rendered to surface overcharges, billing errors, and unauthorised accessorials that can be recovered or disputed.
Function calling (a.k.a. tool use) is the mechanism that lets a large language model invoke external functions, APIs, or code by emitting a structured JSON request. The host application runs the function and returns the result to the model, turning a text generator into an agent that can read systems and take real-world actions.
FX risk, or foreign exchange risk, is the financial risk that movements in currency exchange rates will reduce the value of a company's assets, liabilities, cash flows, or reported earnings. For AR teams, it shows up most directly as open foreign-currency invoices losing value between the date they are booked and the date they are collected.
The General Ledger (GL) is the master accounting record that holds every financial transaction of an organisation, organised by account from the Chart of Accounts. It sits at the top of the finance stack, receiving summary postings from sub-ledgers such as accounts receivable, accounts payable, inventory, payroll and fixed assets, and is the source of the trial balance and statutory financial statements.
Generative AI is a class of artificial intelligence that produces new content, including text, images, code, audio, video, and structured data, rather than only classifying or predicting outcomes from existing inputs.
GoBD, short for Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in elektronischer Form sowie zum Datenzugriff, is the German tax authority's binding standard for keeping and storing electronic accounting records. It requires that invoices, remittances, and ledger entries stay unaltered, timestamped, and traceable, and that auditors can access the underlying data in machine readable form for up to ten years.
A Goods Receipt (GR) is a buyer-side document posted in the buyer's ERP after the receiving team verifies that physical goods (or completed services) arrived as ordered. For AR teams, GR is the silent gate between shipment and payment: without it, the supplier's invoice cannot pass three-way match and stays unpaid.
GS1 is the global not-for-profit body that maintains standards for product, location, and shipment identification. GTIN (Global Trade Item Number) is the GS1-issued unique identifier embedded in barcodes such as UPC, EAN, and ITF-14, and it is the universal product ID used across purchase orders, ASNs, invoices, and EDI transmissions in O2C.
Hedging is the use of financial instruments or operational strategies to offset exposure to variables like exchange rates, interest rates, or commodity prices that would otherwise distort future cash flows and reported earnings.
Indirect Method Cash Flow Forecasting builds the cash projection from forecast net income, then adjusts for non-cash items (depreciation, amortisation, stock-based comp) and changes in working capital (AR, AP, inventory, accrued liabilities). It is the standard approach for horizons beyond 13 weeks, especially 12 to 18 month strategic plans, annual budgets, M&A models, and covenant scenarios.
Interest rate risk is the exposure of a company's cash flows, earnings, or balance sheet value to changes in market interest rates, most acute for businesses carrying floating-rate debt, fixed-rate debt nearing maturity, or sizeable cash investment portfolios.
A commercial document a seller issues to a buyer that itemises goods or services delivered, the amounts owed, applicable taxes, and the terms under which payment is due, creating a legally enforceable receivable.
Invoice Factoring is a financing arrangement where a business sells its accounts receivable to a third party (the factor) at a discount in exchange for immediate cash. It is a working capital accelerator that converts AR to cash before the customer pays, in exchange for a fee that typically runs 1 to 5 percent of invoice value.
ISO 20022 is an international XML-based messaging standard for financial transactions that replaces legacy SWIFT MT formats with a unified, structured data model used across payments, cash management, and securities.
A journal entry is a dated record in the accounting ledger that documents a single financial transaction using balanced debits and credits to specific accounts, with a description and supporting documentation that creates the audit trail behind every reported figure.
A Large Language Model (LLM) is a neural network trained on vast amounts of text that can read, interpret, and generate natural language. In finance, LLMs power the document understanding, email triage, and natural-language interfaces that sit underneath AI-native AR and O2C workflows.
A bank-issued guarantee that the seller will receive payment on time and for the correct amount, provided the seller presents shipping and compliance documents that meet the conditions stated in the LC.
A Liquidity Ratio is any of a family of metrics that measure a company's ability to meet short-term obligations using its short-term assets. The three most common variants are the Current Ratio, Quick Ratio, and Cash Ratio, each progressively stricter about what counts as a liquid asset.
A Lockbox is a banking service where customer payments are sent to a PO Box that the bank manages on behalf of the company. The bank opens the mail, deposits the checks, and forwards the remittance information to the company, accelerating cash availability and reducing internal handling.
Machine Learning (ML) is the branch of AI that builds systems which learn patterns from data and improve with experience, rather than following hand-coded rules. In finance, ML powers payment prediction, dispute classification, credit risk scoring, anomaly detection, and cash flow forecasting at a scale and accuracy that rules alone cannot match.
Master Data Management (MDM) is the discipline of governing, maintaining, and synchronizing the core reference data (customers, vendors, products, accounts, locations) that flows across every enterprise system. For order-to-cash, customer master is the critical MDM domain because it drives credit, billing, collections, tax, and dispute routing.
A Master Services Agreement (MSA) is an overarching contract between two parties that sets the framework of terms, conditions, and processes under which they will conduct future business. Specific deals are executed through Order Forms, Statements of Work (SOWs), or Purchase Orders that reference the MSA, so each new transaction inherits the negotiated legal terms without renegotiation.
Market Development Funds (MDF) and Co-op Advertising are supplier-funded budgets paid to channel partners or retailers to support marketing, promotion, and sales-enablement activity. Retailers typically claim the funds as a deduction against invoice payment, backed by proof of spend such as ad placements, display photos, or paid media invoices.
MT940 is a SWIFT FIN message format that banks use to send prior-day end-of-day account statements to corporate customers, giving treasury and AR teams a structured feed of balances and transactions for cash positioning, reconciliation, and cash application across multiple banks and currencies.
Natural Language Processing (NLP) is the branch of AI that enables machines to read, interpret, and generate human language. In AR and O2C, NLP powers email triage, dispute classification, remittance parsing, and finance copilots, and it sits underneath every modern large language model used in the back office.
Net Working Capital (NWC) is the difference between a company's current assets and current liabilities. It is the precise balance sheet measure of short-term liquidity, indicating whether the business has enough current assets to cover near-term obligations from internal resources.
Notional pooling is a cash management structure where a bank calculates interest on the combined net balance of multiple participating accounts without physically moving funds. Each entity keeps legal title to its own cash, and the bank offsets debit and credit balances mathematically to optimise group-wide interest.
An off-invoice allowance is a trade-promotion discount that a CPG supplier applies directly to the customer invoice at the time of billing, so the retailer pays the net amount and no separate deduction or claim is needed.
On-account cash is customer money that has been received and posted to a specific customer account in the AR ledger, but not yet matched to a particular open invoice. It sits as an open credit on the customer record until intent is identified and the credit is applied, refunded, or otherwise resolved.
Open Banking is a regulatory and technological framework that lets licensed third parties access bank account data and initiate payments via APIs, with the account holder's consent. It powers real-time multi-bank visibility, instant account-to-account payments, and modern treasury connectivity beyond batch file feeds.
Optical Character Recognition (OCR) is software that converts images of typed or handwritten text (scanned invoices, remittance PDFs, cheques, proofs of delivery) into machine-readable data. In AR and O2C, it sits at the front of capture workflows but is increasingly paired with, or replaced by, vision language models for variable-layout documents.
Order to Cash (O2C) is the end-to-end business process that begins when a customer places an order and ends when the resulting payment is received and posted to the general ledger. It spans seven to ten distinct steps across multiple finance and operations teams.
OS&D stands for Over, Short, and Damaged: the logistics category for deliveries where what the retailer or distributor received differs from what the supplier invoiced. In CPG and 3PL contexts, OS&D is one of the largest sources of unauthorised deductions and freight claims.
OTIF (On-Time In-Full) is a retailer compliance programme that fines suppliers for purchase orders arriving late or short, billed as an AR deduction. Walmart's OTIF programme, formalised in 2017, charges suppliers 3 percent of cost of goods sold for non-compliant cases measured against a 98 percent compliance threshold, though thresholds and rates vary by retailer.
Past Due refers to an invoice that has not been paid by its agreed due date. The amount and severity of past due AR is the primary signal collections teams use to prioritise outreach and assess credit risk.
A payment plan is a formal, written agreement that lets a customer pay down an overdue balance in scheduled installments instead of one lump sum. It is a recovery tool that sits between a promise to pay and a write-off, and is typically the last realistic option before a customer goes to a third-party collector.
Payment reconciliation is the process of matching every incoming customer payment to the correct open invoice in the AR sub-ledger and confirming that the daily and period totals tie back to the bank statement, so cash, AR, and the GL all agree.
Payment Terms are the contractual conditions that define when a buyer must pay an invoice, any early-payment discount available, and any penalties for late payment. Common B2B terms include Net 30, 2/10 Net 30, EOM, and CIA, with each variant carrying different working capital and credit risk implications.
Peppol is an international interoperability framework for exchanging structured electronic business documents, including e-invoices, orders, and despatch advices, through a network of certified Access Points governed by OpenPeppol.
Period close is the structured process of finalizing financial records at the end of a reporting period (month, quarter, or year) by cutting off transactions, closing sub-ledgers, reconciling balances, posting adjustments, and producing financial statements that are accurate, complete, and auditable.
A post-audit claim is a retrospective deduction or recovery demand raised by a retailer, or a third-party audit firm acting on their behalf, months or years after the original transaction, asserting that the supplier owes money for missed promotional allowances, unprocessed credits, pricing errors, freight overcharges, or other historical discrepancies.
Predictive modeling is the practice of building statistical or machine learning models that estimate future outcomes from historical data, such as whether a customer will pay on time, when an invoice will clear, or how likely a deduction is to be valid.
A preliminary invoice issued before delivery or final commercial invoicing, used to confirm pricing, terms, and shipment details so the buyer can arrange customs clearance, prepayment, or letter of credit financing. It is not a tax document and does not create a legal demand for payment.
Promise to Pay (PTP) is a commitment from a customer to pay an overdue invoice by a specific future date. It is captured by collections teams during dunning outreach and used to schedule follow-up, prioritise collection effort, and feed cash flow forecasts.
Proof of Delivery (POD) is carrier-signed documentation that confirms goods arrived at the customer location, capturing signature, timestamp, quantity, and condition. It is the primary evidence AR teams use to dispute shortage, damage, and OTIF deductions taken by retailers.
A Purchase Order (PO) is a formal document issued by a buyer to a seller specifying the products or services to be purchased, quantities, agreed prices, and delivery terms. Once accepted by the seller, the PO becomes a legally binding contract and acts as the reference key that links every downstream document in the order-to-cash cycle.
The Quick Ratio (also called the acid-test ratio) measures whether a company can meet its short-term liabilities with its most liquid assets, excluding inventory. It is a more conservative liquidity measure than the Current Ratio because it strips out inventory that may not convert to cash quickly.
Quote-to-Cash (QTC) is the end-to-end business process from initial customer quote through to cash collected and posted to the general ledger. It is broader than Order-to-Cash because it includes the pre-sale quoting and configuration stages that Order-to-Cash typically starts after.
Receivables Turnover Ratio measures how many times a company collects its average accounts receivable balance during a period, typically annually. It is the operational counterpart to DSO and indicates how efficiently the AR cycle is converting credit sales to cash.
Remittance Advice is the document or data feed a customer sends with a payment indicating which invoices the payment covers, any deductions taken, and dispute references. It is the essential input that lets the AR team match incoming cash to open receivables.
Retrieval Augmented Generation (RAG) is an AI technique that combines a Large Language Model with an external knowledge retrieval system. Instead of relying only on what the model learned during training, RAG fetches relevant context from your own data sources at query time and feeds it into the prompt, grounding the response in current, company-specific information.
Revenue Recognition is the accounting principle and framework for recognising revenue when control of goods or services transfers to the customer. The current standards are ASC 606 (US GAAP) and IFRS 15 (international), both based on the same five-step model that aligns revenue timing with the substance of the transaction.
Robotic Process Automation (RPA) uses software bots to mimic human keystrokes and clicks across business applications, executing repetitive, rule-based tasks like data entry, invoice posting and reconciliation. In AR and O2C, RPA was the dominant automation paradigm of the 2010s, but its brittleness and maintenance overhead are pushing finance teams toward agentic AI for the same workflows.
A rolling forecast is a financial projection that is continuously extended by adding a new period (week, month, or quarter) as the most recent one closes, maintaining a constant forward horizon rather than freezing at a fiscal year-end.
Sales tax is a consumption tax levied by US state and local governments on the sale of goods (and increasingly services), collected by the seller from the buyer at point of sale and remitted to the relevant tax authority. Unlike VAT, it is a single-stage tax applied only at final sale, with no federal layer and over 13,000 local jurisdictions in play.
Same-Day ACH is an expedited variant of the US ACH network that clears and settles credit and debit transfers within the same business day across three Nacha-mandated settlement windows, with a per-transaction limit of approximately 920,000 euros (USD 1M).
SAP S/4HANA is SAP's modern ERP suite, built on the in-memory HANA database, that replaced SAP ECC as SAP's flagship platform. For finance and AR teams, it underpins core order-to-cash processes such as invoicing, credit management, and receivables accounting, and serves as the system of record that cash application, collections, and deductions tools must integrate with.
A scanline is a structured, machine-readable reference line printed on an invoice or payment slip (KID in Norway, OCR-reference in Sweden, FIK in Denmark, viitenumero in Finland, ESR or QR-bill reference in Switzerland) that lets the payer transmit a single number which uniquely identifies the invoice, enabling straight-through cash application when the bank file returns it.
SEPA (Single Euro Payments Area) is the EU-led payment integration initiative that harmonises euro-denominated electronic payments across 36 countries, using ISO 20022 XML and IBANs to make cross-border euro transfers work identically to domestic ones.
A Short Pay is when a customer pays less than the full invoice amount, either deliberately due to a deduction or dispute, or in error. Short pays are the operational trigger for most deduction and dispute workflows in B2B AR, and the largest source of variance between invoiced revenue and cash collected.
Skip tracing is the process of locating a debtor, or the current decision-maker at a debtor company, whose contact details have gone stale, who has moved, restructured, or who is deliberately avoiding contact. In B2B AR, it typically means finding the new AP lead, current registered office, or successor entity when the original point of contact has disappeared.
Skonto is a German early-payment cash discount: the buyer may deduct a small percentage from the invoice total if they pay within a short window instead of the full net term. A common payment condition is "2 % Skonto bei Zahlung innerhalb von 10 Tagen, sonst netto 30 Tage." It speeds up cash inflow for sellers but creates an AR headache when buyers take the discount after the deadline has passed.
A Slotting Fee is a payment a manufacturer makes to a retailer to secure shelf space for a new product. Typical fees range from 5,000 to 50,000 euros per SKU per retail chain, with premium endcap and category captain positions cited as high as 75,000 euros per SKU. The fees are often paid as invoice deductions rather than separate cash transactions.
A Statement of Account (SOA) is a periodic summary a supplier sends to a customer listing all open invoices, payments received, credits applied, aging buckets, and the current balance owed. It is the primary reconciliation document in B2B AR and a core tool for collections and month-end close.
Straight-Through Processing (STP) is the share of incoming payments that are automatically matched to open invoices and posted to the general ledger with no human intervention. It is the headline metric for cash application performance and a direct measure of automation effectiveness.
A sub-ledger is a subsidiary accounting record that holds the transaction-level detail behind a single General Ledger control account. The AR sub-ledger, for example, stores every open invoice, payment, credit memo, and write-off by customer, and its balance must reconcile to the AR control account in the GL.
A tabular foundation model is a single pre-trained neural network that makes predictions on new tabular datasets in a zero-shot or in-context-learning manner, without per-dataset training or feature engineering.
A tax invoice is an invoice that meets the specific legal content requirements set by a tax authority, allowing the buyer to claim input VAT or GST recovery and giving the supplier a compliant record of taxable supply.
Terms of Sale are the complete set of commercial conditions that govern a transaction between supplier and customer, covering payment, delivery, title transfer, risk, warranties, returns, disputes, taxes, currency, and applicable law.
Three-way match is the buyer-side accounts payable control that verifies a supplier invoice against the original purchase order and the goods receipt before approving payment, ensuring the goods or services were ordered, received, and billed consistently.
Time series forecasting is the practice of predicting future values of a variable indexed by time, using historical observations and statistical, machine learning, or deep learning models that capture trend, seasonality, and autocorrelation.
A time series foundation model (TSFM) is a large neural network pre-trained on millions of historical time series across domains, enabling zero-shot or few-shot forecasting on new series without per-series training. For finance teams, TSFMs collapse fleets of per-customer or per-entity forecasting models into a single shared model that generalises to AR payment timing, cash flow, FX, and demand forecasting.
Trade credit is the financing a supplier extends to a buyer by allowing payment after delivery rather than at the point of sale. It is the largest source of short-term commercial financing in the world and the economic mechanism behind every Net 30 or Net 60 invoice.
Trade Deductions are reductions customers (typically large retailers) take from invoice payments to reflect agreed trade promotions, allowances, and contractual programmes. They are a normal part of CPG and consumer goods commerce, but they are also the largest single source of unauthorised short-pays and revenue leakage when not actively managed.
Transactional data is the high-volume, time-stamped record of business events (orders placed, invoices raised, payments received, journal entries posted) that documents what happened, when, and against which master data entities. In order-to-cash, it is the raw material feeding the general ledger, the sub-ledger, and every AI model that predicts payment behaviour or detects anomalies.
A Transformer is a deep neural network architecture, introduced by Google researchers in 2017, that uses self-attention to process sequences in parallel and is the foundation behind virtually every modern large language model, vision model, and multimodal AI system.
A Treasury Management System (TMS) is a software platform that centralizes treasury operations including cash visibility, liquidity forecasting, bank connectivity, payments, FX and interest rate risk, debt and investment management, and intercompany settlement. A TMS gives treasurers a single source of truth for global cash and the workflows to manage it.
Value Added Tax (VAT) is a consumption tax charged on the value added at each stage of production and distribution. Businesses collect VAT on sales (output VAT), reclaim VAT on purchases (input VAT), and remit the net difference to the tax authority. For AR teams, VAT determines invoice structure, reporting cadence, and a meaningful share of compliance risk.
A vector database is a database optimised for storing and querying high-dimensional vectors (embeddings) using similarity search rather than exact match. It returns the nearest results based on cosine similarity, dot product, or Euclidean distance, which is what makes RAG, semantic search, and AI-native AR workflows possible at scale.
Verfahrensdokumentation is the process documentation the GoBD, an administrative directive of the German Federal Ministry of Finance, require for every IT system that creates, processes, or stores tax-relevant data, including invoicing, cash application, and accounting. It describes the full data lifecycle from capture through archiving, the internal controls in place, and how records stay complete, unalterable, and retrievable during a tax audit.
A virtual account is a sub-account number, usually a virtual IBAN, that looks like a real bank account to the payer but is actually an alias mapped by the bank to a single physical master account plus a reference, letting receivers identify the payer or invoice automatically from the destination account.
A Vision Language Model (VLM) is an AI model that combines computer vision and natural language understanding in a single architecture, allowing it to read, interpret and reason about documents the way a human would. In AR and O2C, VLMs extract data from invoices, remittances, cheques and deduction packets at 95 to 99 percent field accuracy, well above what classical OCR achieves on variable or handwritten content.
A Wire Transfer is a same-day, real-time gross-settlement transfer of funds between banks. In B2B operations it is typically used for high-value or cross-border payments where speed and irrevocability matter more than cost, with the US Fedwire, CHIPS, and international SWIFT networks providing the underlying rails.
Withholding tax (WHT) is a tax the payer deducts from a payment before sending it to the supplier, then remits to the tax authority on the supplier's behalf. The supplier receives a net amount plus a WHT certificate, which can often be claimed as a foreign tax credit at home.
Working Capital is the cash a business has available to fund day-to-day operations after subtracting short-term liabilities from current assets. It is the liquidity buffer between collecting from customers and paying suppliers.
A Write-Off is the accounting action of removing an uncollectible receivable from the books and recognising it as an expense. It is the formal end of the AR lifecycle for invoices that could not be converted to cash, representing the realised cost of credit sales that did not work out.
XRechnung is the German government's mandatory electronic invoice standard for business-to-government (B2G) transactions, based on the European standard EN 16931. It is a pure XML format (UBL or CII syntax) with no visual layout, built for straight-through processing by public-sector accounts payable systems. Since November 2020, it has been required for invoicing most German federal, and increasingly state and municipal, public entities.
A Zero Balance Account (ZBA) is a bank account that automatically maintains a closing balance of zero each day by sweeping surplus funds to, or pulling deficit funds from, a designated concentration master account. ZBAs let multi-entity corporates centralise liquidity without forcing every business unit to share a single operating account.
ZUGFeRD is a German hybrid e-invoice standard that embeds a structured XML data set inside a standard, human-readable PDF, letting one file serve as both a printable document and machine-readable data. Unlike XRechnung's XML-only format, ZUGFeRD works for B2B and B2C invoicing where recipients may lack automated intake, while still enabling straight-through data extraction for accounts payable and receivable systems.
A 13-Week Cash Flow Forecast is a rolling weekly projection of cash inflows and outflows over the next 13 weeks. It is the treasury standard for short-term liquidity management, giving CFOs and treasurers a quarter-ahead view of the cash position required to operate the business.
