Payment terms specify when and how a buyer must pay, including due-date rules, discounts, currencies, fees, and dispute procedures.
Payment terms are the agreed conditions governing when, how, and in what amount a buyer must pay a seller. They commonly specify the due-date calculation, payment method and currency, early-payment discount, late-payment consequences, deposit requirements, and procedures for disputed invoices.
Useful terms address more than a number of days:
| Element | Questions to answer |
|---|---|
| Amount and currency | What amount is payable, in which currency, and are tax, freight, insurance, or withholding included? |
| Date anchor | Does timing begin on invoice date, shipment, delivery, acceptance, statement date, or receipt of a valid invoice? |
| Due-date rule | Are days calendar or business days, and what happens on weekends or holidays? |
| Discount | What percentage applies, to which charges, by what date, and are partial payments eligible? |
| Payment method | Which account, rail, remittance information, or documentary process must be used? |
| Disputes | How quickly must discrepancies be reported, and may only the disputed amount be withheld? |
| Late payment | Does the agreement permit interest, fees, suspension, collection, or acceleration? |
| Evidence | Which purchase order, delivery record, acceptance certificate, tax document, and invoice number support payment? |
These details reduce avoidable disputes and make accounts-payable and accounts-receivable records easier to reconcile.
| Term | Plain-English meaning | Important qualification |
|---|---|---|
| Due on receipt | Payment is requested when a valid invoice is received | “Receipt” and processing time should be defined |
| Net 30 | Full invoice amount due 30 days after the agreed starting event | Does not necessarily mean 30 days after delivery |
| 1/10, net 30 | 1% discount during the first 10 days; otherwise full amount due by day 30 | Eligibility and date anchor still need definition |
| Cash in advance | Payment occurs before shipment or performance | Shifts nonperformance exposure toward the buyer |
| Cash on delivery | Payment occurs at delivery under the agreed process | Inspection and failed-delivery rules still matter |
| Milestone billing | Amounts become due as defined project stages are completed | Each milestone needs objective evidence |
| End of month | Due date is tied to month-end, sometimes with an additional number of days | The exact convention varies and should be written out |
Abbreviations are useful only when both parties apply the same convention. Writing the actual discount date and final due date on the invoice is safer than relying on shorthand alone.
The dates should connect the commercial agreement to the cash receipt and accounting records:

The diagram is illustrative. Some agreements start the payment clock at shipment, acceptance, statement date, or another event rather than invoice receipt.
Assume a supplier issues a valid $24,000 invoice with 2/10, net 30 terms. The agreement says day 1 is the day after the buyer receives the invoice.
| Payment timing | Calculation | Amount paid |
|---|---|---|
| By the discount deadline | $24,000 - ($24,000 x 2%) | $23,520 |
| After the discount deadline but by final due date | Full invoice | $24,000 |
| Discount amount | $24,000 x 2% | $480 |
If the buyer does not take the discount, it keeps $23,520 for 20 additional days and then pays $480 more. The periodic financing cost relative to the discounted payment is $480 / $23,520, or approximately 2.04% for 20 days.
One way to annualize that tradeoff is:
Here, (d) is the discount rate, (D) is the discount day, and (N) is the net due day. For 2/10, net 30, the effective annualized rate is approximately 44.6% under a 365-day compounding convention.
That figure is a comparison tool, not an invoice penalty, guaranteed return, or conclusion that the buyer should always pay early. Liquidity needs, borrowing limits, tax, transaction costs, discount eligibility, and the risk of paying a disputed invoice can change the decision.
| Buyer review | Seller review |
|---|---|
| Verify goods, services, approvals, tax, and invoice data before release | Confirm buyer credit, limits, documentation, and collection history |
| Compare discount economics with available cash and funding cost | Compare faster cash with discount cost and expected credit losses |
| Schedule payment early enough to meet the bank and supplier cutoff | State how payment timing is measured and when funds count as received |
| Reconcile remittance to the correct invoice and legal entity | Apply receipts promptly and investigate short pays or deductions |
| Preserve evidence for disputed and approved amounts | Monitor aging, concentration, disputes, and overdue exposure |
The buyer’s accounts payable and the seller’s account receivable should reflect the same commercial event even though their internal approval and posting dates may differ.
