O2C
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.
O2C is one of two core financial workflows in any business (the other is Procure to Pay). It governs how quickly revenue converts to cash, which determines working capital, growth funding capacity, and lender confidence. A well-run O2C cycle takes 30 to 45 days from order to cash for B2B businesses. A poorly-run cycle takes 60 to 90 days or more, tying up cash that could fund growth.
Most O2C frameworks break the cycle into seven sequential steps.
Some frameworks add three additional steps: credit risk monitoring (ongoing), reporting and analytics (continuous), and bad debt write-off (when collections fail). Different industries emphasise different steps. CPG companies fight deductions; SaaS companies focus on invoicing automation; healthcare deals with complex payer mix.
Most enterprise O2C cycles are fragmented across teams that don't share systems or data in real time. Credit management sits in finance. Order entry sits in sales operations. Fulfilment sits in supply chain. Invoicing sits in AR. Collections sits in credit and collections. Cash application sits in AR operations. Disputes sit in customer service or trade promotion management.
The result is a workflow where each handoff loses information. The sales rep doesn't see the credit limit. The collections team doesn't see the dispute investigation status. The cash application analyst doesn't see the customer's payment history with that retailer. Coordination overhead consumes 30 to 40% of AR analyst time and creates the cash conversion delays that drag DSO upward.
ERPs are great at recording transactions but they were not designed for workflow orchestration across functions. Most O2C automation lives in bolt-on tools that each solve one step: a cash application tool, a collections platform, a deductions workflow, a credit risk system. These tools rarely talk to each other in real time, which is why the structural fragmentation persists even after companies invest in automation.
Agentic O2C platforms consolidate the seven steps into a single workflow with shared institutional memory. The same AI agent that reads a remittance advice in cash application can update the customer's payment history, which feeds the credit limit recommendation for the next order, which informs the collections priority on the next overdue invoice. Persistent memory across steps eliminates the handoff information loss that legacy tools accept as inevitable. For mid-market companies, agentic O2C deployments typically deliver 8 to 15 day DSO reduction within 90 days plus 30 to 50% reduction in coordination overhead.
The seven standard steps: credit management, order entry, order fulfilment, invoicing, collections, cash application, and disputes/deductions handling. Some frameworks add credit risk monitoring, ongoing reporting, and bad debt write-off as additional steps. Different industries emphasise different steps based on their structural realities (CPG fights deductions, SaaS optimises invoicing, healthcare manages payer mix).
Accounts Receivable is one piece of Order to Cash. AR covers the invoice-to-cash portion (steps 4 through 7 of O2C). Order to Cash adds the upstream steps: credit management, order entry, and order fulfilment. O2C is the end-to-end commercial process. AR is the finance team's slice of it.
B2B benchmarks vary by industry. Software and SaaS run 30 to 45 days end-to-end. Manufacturing runs 45 to 65 days. CPG selling to large retailers runs 60 to 80 days because retailers extract long payment terms. Healthcare runs 50 to 80 days depending on payer mix. The DSO metric captures the back half of this cycle (invoice to cash); the full O2C cycle adds the order-to-invoice time on the front end.
O2C software falls into four categories: ERP-native modules (SAP, Oracle, NetSuite all include O2C functionality), integrated AR platforms (HighRadius, Billtrust, BlackLine, Esker each cover multiple O2C steps), point solutions (separate tools for credit, cash app, collections, deductions), and agentic O2C platforms (newer category, agentic AI across the full cycle). Best fit depends on company size, industry, and how much of the workflow needs autonomous execution.
The ERP is the system of record for O2C transactions: it stores customer master data, credit limits, open orders, invoices, payments, and journal entries. It is excellent at recording these transactions but it is not designed for workflow orchestration, document processing, or autonomous execution. That is why O2C automation typically sits in tools above the ERP, with the ERP as the source-of-truth for the underlying data.
The headline metric is Days Sales Outstanding (DSO), capturing how long it takes to convert sales into cash. Layer in Cash Conversion Cycle (CCC) for the full working capital view, Collections Effectiveness Index (CEI) for the collections team's specific contribution, and First-Time Match Rate for cash application efficiency. Bad Debt Ratio captures the failure mode (write-offs as a percentage of revenue). Trend matters more than absolute level: a CPG company at DSO 75 improving is doing better than a SaaS company at DSO 50 drifting upward.
