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.
Payment Terms are the single most-negotiated commercial variable in B2B contracts after price. They determine how quickly cash returns to the seller, how much working capital the buyer ties up, and how the credit risk is shared between the two parties. A one-day shift in payment terms across a large B2B portfolio translates directly into 1 over 365 of annual revenue in working capital. For CFOs and AR leaders, payment terms are the headline lever on DSO and the foundation of credit policy.
The most commonly used B2B payment terms are:
Each variant carries different working capital, credit risk, and customer relationship implications.
Discount terms like 2/10 Net 30 offer a meaningful trade-off. The buyer can pay 2 percent less if they pay 20 days earlier (day 10 instead of day 30). The implied annual rate is roughly (2 / 98) x (365 / 20) = 37 percent APR, the equivalent return the buyer earns on their cash by taking the discount.
For most B2B buyers, the implied APR comfortably exceeds their cost of capital, making the discount worth taking. Best-practice AP teams calculate the implied APR on every discount offer and automate capture of discounts above their cost-of-capital threshold.
Net 30 customer paying on day 30 generates DSO of 30 days. Net 60 paying on day 60 generates DSO of 60. Same operational performance, different headline number purely due to terms. This is why DSO must be benchmarked within industry and customer mix; cross-industry DSO comparisons without payment-term context mislead.
A separate metric, Days Beyond Terms, isolates the discretionary overdue portion and is more useful for collections prioritisation across customer portfolios with different agreed terms.
Mistake 1: Default terms without segmentation. Applying Net 30 to every customer regardless of credit profile or strategic value ignores the opportunity to use shorter terms for higher-risk accounts and longer terms for strategic concessions.
Mistake 2: Salesforce-driven term concessions. When sales routinely offers Net 60 or Net 90 to close deals without finance approval, DSO drifts upward without any operational issue to fix.
Mistake 3: Missing early-payment discounts. Both sides of the trade lose value when discounts are offered but not taken. For sellers, discount uptake brings cash in faster. For buyers, the implied APR usually beats cost of capital.
Mistake 4: Not enforcing terms. Customers who routinely pay past terms without consequence learn that the contractual deadline is advisory. Active dunning and credit hold enforcement defend the negotiated terms.
AI-native AR platforms turn payment terms from a static contract field into an actively managed lever:
For sellers, AI-driven term management combined with full overdue coverage typically delivers 8 to 15 day DSO reductions within 90 days of deployment.
Net 30 means the buyer must pay the full invoice amount within 30 days of the invoice date. It is one of the most common B2B payment terms, used as a default in many industries. Net 60 and Net 90 extend the same logic to 60 and 90 days respectively.
2/10 Net 30 means the buyer can take a 2 percent discount if they pay within 10 days; otherwise the full amount is due by day 30. The implied APR on the discount is roughly 37 percent, making it worth taking for most buyers whose cost of capital is lower.
Take the discount when the implied annual rate exceeds your cost of capital. A 2/10 Net 30 discount equals roughly 37 percent APR (you earn 2 percent for paying 20 days earlier). For most companies, that comfortably beats cost of capital and the discount is worth taking. Skip it only if cost of capital is very high or cash position is constrained.
DSO is directly affected by the agreed payment terms. A customer on Net 60 paying on day 60 generates DSO of 60 days with no operational issue. The same operational performance with Net 30 terms would show DSO of 30. Cross-industry DSO comparisons without payment-term context mislead, which is why Days Beyond Terms is often the better collections metric.
Term changes typically require contract amendment with customer agreement. Unilateral changes risk dispute and customer relationship damage. Best practice is to negotiate terms at contract renewal or at the start of new orders rather than mid-contract. For chronic late payers, the lever is credit hold or term tightening at the next purchase, not retroactive change.
Net 30 means 30 days from invoice date. 30 days EOM (End of Month) means 30 days from the end of the month in which the invoice was issued. A January 5 invoice on Net 30 is due February 4; the same invoice on 30 days EOM is due March 2. EOM terms structurally extend DSO by an average 15 days versus Net terms.
