Supplier trade credit: buying now and paying later is still working-capital finance

Trade credit is the financing created when a supplier delivers goods or services before the customer pays. It can be one of the largest sources of short-term working capital in a business because the supplier effectively funds inventory or operations for 30, 60 or more days.

Payment terms create a financing period

British Business Bank research defines trade credit as the agreed deferral between delivery and payment. When a supplier gives 60-day terms, the buyer uses the goods or services before cash leaves the bank.

Treat that period as finance. Accounts payable is not free cash; it is money the company has committed to suppliers on known due dates.

Suppliers can set and change credit limits

A supplier may approve a maximum outstanding balance based on the buyer's creditworthiness and payment history. A late-paying customer can have terms shortened or move to payment in advance.

Track supplier credit limits alongside purchase orders. A large order can fail operationally if procurement assumes the supplier will extend unlimited credit.

Early-payment discounts have an implied financing value

A supplier offering 2 percent discount for payment in 10 days instead of 60 days is effectively pricing the cost of 50 days of credit. The buyer should compare the discount with its cost of cash.

Sometimes paying early is economically attractive even when the company could keep the cash longer. Calculate the annualised value rather than deciding from habit.

Do not use overdue suppliers as involuntary finance

Paying after the agreed date can damage relationships, reduce future credit and create statutory late-payment interest or compensation in commercial transactions.

If cash is tight, speak to the supplier and agree revised terms rather than silently stretching payment. An agreed extension is different from an overdue debt.

Put supplier terms into the cash-flow forecast

Forecast purchases by actual due date, not invoice date. A growth period can produce healthy profit while payables build quickly and create a large future cash requirement.

Track days payable outstanding but do not optimise it blindly. Extending every supplier can weaken the supply chain and lose valuable early-payment discounts.

Use supplier credit strategically with critical vendors

Reliable payment can earn better terms over time. Critical suppliers may be willing to increase limits or offer staged terms when they trust the buyer's history.

Review the most important supplier relationships separately from routine small vendors. The financial value of keeping a strategic supplier confident can exceed the short-term benefit of delaying one invoice.

Worked example: a supplier offers 2 percent discount if a £100,000 invoice is paid in 10 days instead of the normal 60 days. Paying early saves £2,000 for using cash 50 days sooner. The implied annualised return on that cash can be far above an ordinary savings rate, so the business should compare the discount with its own borrowing or liquidity cost rather than automatically taking the full 60 days.

Track supplier terms in the ERP master and require procurement approval before agreeing unusually short payment terms. A buyer can negotiate an attractive unit price while silently giving away working capital by accepting payment seven days after delivery instead of 45 days.

Use supplier ageing to identify concentration risk. If the company owes one critical vendor £800,000 and repeatedly pays late, that supplier can become a financing dependency. A disruption in terms can create a sudden cash requirement that is just as serious as a bank reducing an overdraft.

Create a supplier-term exception report. Procurement should flag purchases that depart from the approved 30-, 45- or 60-day terms, especially prepayments and deposits. One large supplier moving from 60 days to cash in advance can create the same liquidity impact as losing a bank facility.

Where several suppliers offer dynamic discounting, compare offers consistently. A 1 percent discount for paying 20 days early and a 2 percent discount for paying 50 days early have different annualised economics. Treasury can prioritise the discounts that deliver the strongest return on available cash.

Pay critical small suppliers fairly even when the company has bargaining power. Extending terms can improve the buyer's working capital while transferring stress down the supply chain. Supplier resilience is part of financial resilience, especially where replacement vendors are difficult to find.

Track whether supplier credit is insured. Some suppliers can reduce or withdraw terms when their trade-credit insurer lowers the buyer's limit, even if the commercial relationship remains good. A buyer should not assume agreed terms are permanent if the supplier's own financing or insurance depends on third-party credit decisions.

Include trade creditors in refinancing discussions. A bank can look at stretched payables as hidden borrowing, especially where suppliers are repeatedly overdue. Improving supplier payment behaviour can strengthen the overall finance case, not only procurement relationships.
