Most companies negotiate them once and never check them again. SM **Sonal Mehta**Oct 07, 2021 ยท 4 min read In business to business trade, suppliers rarely get paid on delivery. The buyer receives the goods or service, the supplier sends an invoice, and payment follows days or weeks later under the payment terms in the contract. Those terms decide when money leaves the buyer's account and when it reaches the supplier's. That makes them one of the most direct levers on cash flow either side has. Yet many organizations do not actively track whether they are paying to terms. [Supply Chain Dive](https://www.supplychaindive.com/news/late-payments-supplier-credit-policy-cash-flow/511232/) reported research finding that some businesses do not monitor their payment processes at all. This guide, refreshed for 2026, explains how payment terms work, how to negotiate them sensibly and how software keeps both sides to what they agreed. Key takeaways - Payment terms are a cash flow decision for both buyer and supplier - Pushing terms too far can hurt suppliers and cost the buyer discounts and goodwill - Paying late against agreed terms damages relationships and creates hidden costs - Terms only protect cash flow if accounts payable can see and apply them - Source to pay software links contract terms to invoices and payments ## How procurement payment terms work Payment terms specify when an invoice must be paid and on what conditions. The most common form is net terms: net 30, net 45, net 60 or net 90 means payment is due that many days after a set trigger, usually the invoice date or invoice approval. Terms may also include early payment discounts, late payment interest, milestone or staged payments, and rules for disputed invoices. Buyers naturally want longer terms, which keep cash in the business longer. Suppliers want shorter ones. Suppliers will often accept longer terms from customers they trust, but only up to a point, and they price that risk into their offers. Our glossary explains the common forms: [net 30](https://aavenir.com/glossary/net-30/), [net 45](https://aavenir.com/glossary/net-45/) and [net 90](https://aavenir.com/glossary/net-90/). ## Negotiating payment terms Good payment terms balance the buyer's cash needs with the supplier's ability to keep delivering. Pushing terms far beyond what a supplier can carry, especially a small one, can backfire. The supplier has paid for materials and labor up front and may struggle to fund the gap, which shows up as higher prices, lower priority or a supplier that fails at the worst moment. ### Questions to settle in negotiation - What is the trigger: invoice date, receipt of goods or invoice approval? - Is there an early payment discount, and is it worth more than holding the cash? - What happens to disputed invoices, and how fast must disputes be raised? - Are there milestone or staged payments for large projects? - Does late payment carry interest or other consequences? - Do any local laws set maximum payment periods for certain suppliers? Finance and procurement should agree standard terms by supplier type, so negotiators know where they can flex. Tools such as [dynamic discounting](https://aavenir.com/glossary/dynamic-discounting/) let buyers offer earlier payment in return for a discount when they have spare cash. ## When agreed terms are not kept Consider a small supplier to a large packaging company. The supplier asked for 30 day terms, the buyer imposed 60 days from invoice approval, and in practice payments arrived even later and only after repeated follow up. Both sides lost. | Impact on the supplier | Impact on the buyer | | Unpredictable cash flow after many follow ups | Accounts payable cannot see what is due and when | | --- | --- | | Difficulty paying taxes, staff and its own suppliers on time | Missed early payment and volume discounts written into the contract | | Reduced working hours or capacity | Bunched payments that strain the buyer's own cash flow | | Reluctance to chase payment for fear of losing the contract | A weaker relationship and less goodwill when supply is tight | Paying to agreed terms is not just fair. It protects both sides' cash flow, reduces risk and keeps relationships workable. ## Why terms get lost between contract and payment The usual cause is a gap between procurement and accounts payable. Procurement negotiates terms in the contract. Accounts payable pays from the supplier record in the finance system. If the agreed terms never reach the supplier record, or a contract is silent on terms, the default applies, which may be wrong for both sides. Discounts written into the contract are invisible to the people processing invoices. Invoice approval delays add to the problem. If the clock starts at approval, slow approvals push payment later without anyone deciding to. ## How source to pay software helps Source to pay software connects the contract to the invoice and the payment, so terms are applied as agreed. - Supplier onboarding captures the right banking, tax and payment term information from the start - AI extracts payment terms and discounts from each contract, and flags contracts that are silent for a person to set standard terms - Invoices are checked against contract terms, prices and purchase orders before approval - Approval workflows have time limits, so invoices do not sit waiting - Alerts show upcoming due dates and discount windows - Reports show on time payment rates by supplier and business unit [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/) reads invoices, matches them to contracts and purchase orders and routes exceptions, while [Onboardingflow](https://aavenir.com/solutions/vendor-onboarding-software/) captures supplier details at onboarding. The [invoice to contract compliance](https://aavenir.com/use-cases/invoice-to-contract-compliance/) use case shows how agreed terms flow through to payment. A person approves every AI result. ## Both sides of the ledger Most companies are both buyers and suppliers. The terms you negotiate on the buy side affect your suppliers' cash flow, and the terms your customers impose affect yours. Treating payment terms as a managed contract obligation on both sides, with owners, monitoring and reporting, gives finance a far clearer view of cash in and cash out. On the sell side, tracking customer payment terms and late payment clauses supports collections in the same way. ## The bottom line Payment terms are negotiated in the contract but realized in accounts payable. Agree sensible terms, make sure they reach the people who pay invoices, and use software to apply them, capture discounts and keep payments on time. Cash flow improves on both sides, and so do supplier relationships. ### In this article - How procurement payment terms work - Negotiating payment terms - When agreed terms are not kept - Why terms get lost between contract and payment - How source to pay software helps - Both sides of the ledger **See invoices matched to contract terms**We will show payment terms extracted from contracts and applied in accounts payable.

Payment terms set when and how a buyer pays a supplier, for example net 45 from invoice date. They can include early payment discounts, late payment interest, staged payments and dispute rules. They directly shape cash flow for both parties. Learn more about [net 45](https://aavenir.com/glossary/net-45/). ### ### Why do companies pay suppliers late? Common causes are slow invoice approvals, payment terms that never reached the finance system, disputes that are not resolved quickly and deliberate cash management. Late payment strains suppliers and can cost the buyer discounts and goodwill. Read about [invoice approval](https://aavenir.com/glossary/invoice-approval/). ### ### How can software protect cash flow through payment terms? Software extracts payment terms from contracts, checks invoices against them, enforces approval time limits and alerts teams to due dates and discount windows. That keeps payments on time and captures value written into contracts. See how [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/) connects invoices to contract terms.
