Trade Credit: The Invisible Loan Inside a Sale
Trade credit is the financial mechanism behind the waiting problem in EU customer-supplier relationships. This chapter focuses on what an open-account sale finances, who bears the cost while an invoice is unpaid, and why the same payment term can be sensible in one industry yet damaging in another. The goal is to make the invoice legible as an economic relationship: the buyer receives time, while the supplier carries the risk that time will become a cash shortage.
What the unpaid invoice finances
Business-to-business trade credit begins with an ordinary transaction. A supplier delivers goods or performs a service, sends an invoice, and collects the money later. No bank loan application is required at the moment of delivery. Yet the economic effect resembles short-term financing. The customer has received value and can use, resell, or build on it before paying. The supplier has completed the work but still has to wait to recover the cash used to produce and deliver it.
For the customer, the unpaid invoice is a potential interest-free source of short-term finance. “Interest-free” describes the basic open-account arrangement: the customer is not separately charged interest simply because the agreed payment date has not arrived. The supplier, however, bears an implied cost. Their money is tied up in an outstanding receivable instead of being available for materials, wages, rent, taxes, debt service, or the next order. The supplier may have to fund that gap from retained cash or from another source of credit.
Consider a hypothetical supplier that delivers €100,000 of equipment on the first day of a quarter under a 60-day term. The supplier's income statement may eventually show a profitable sale, but the sale proceeds are not yet spendable cash. During those 60 days, the supplier may need to pay its own manufacturers, transport providers, and employees. If the customer pays on day 60, the financing interval was built into the commercial agreement. If payment arrives on day 90, the customer has used an additional 30 days of the supplier's liquidity. The supplier still owns a claim, but an unpaid claim cannot directly settle a bill that is due today.
This is the first reason a customer delay can become a supplier delay. The supplier's payable calendar does not necessarily move when the customer's payment moves. A materials vendor may still expect payment on its original date. A lender may still debit an instalment. Payroll may still fall due at the end of the month. The supplier can respond by using cash, arranging a loan, financing or selling the receivable, asking for more time, reducing purchases, or postponing its own payment. The last option turns the original customer's financing benefit into a new supplier's financing burden.
Trade credit is not a marginal substitute for formal finance. The Federal Reserve study reports that 60% of small businesses in the 2003 Survey of Small Business Finances used trade-credit accounts. Among small businesses that used trade credit, the median firm made 80% of its purchases through it. In a separate 2014 poll of firms that provided B2B credit to small businesses, respondents said that 82.7% of small-business transactions were open-account sales. Those figures are old and use different samples, but they show why the payment chain matters: supplier credit can be one of the most available ways for a small customer to keep operating.
That availability creates a two-sided dependency. The buyer may need time because it must hold inventory, complete a project, or wait for its own customers. The seller may offer time because winning the account is commercially valuable. If the arrangement remains within the agreed term, both sides may regard it as a workable exchange. The buyer gets operating flexibility; the seller gets a sale and expects a predictable conversion from receivable to cash. The risk appears when the expected conversion is slower than the supplier's obligations.
The difference between a receivable and cash is central here. A receivable is a claim on a customer, not a payment already in the supplier's account. Its value depends on when the customer pays and whether the customer can pay. While the claim is outstanding, the supplier may have to keep financing the inputs used for the sale. If the supplier has a steady stream of other receipts, it can use those receipts to cover the gap. If several customers pay slowly at the same time, the supplier's claims can grow while usable cash shrinks. A profitable order can then increase the need for short-term funding instead of relieving it.
The buyer's benefit is also not costless in a wider sense. A customer that relies heavily on supplier credit may be exposed if suppliers shorten terms or stop delivering. A supplier that offers generous terms may win or retain business, but it accepts the risk of delayed collection and may need its own liquidity buffer. The relationship works when both sides understand the timing and can carry the risks they have accepted. It becomes unstable when the buyer treats the supplier's willingness to wait as permanent financing and the supplier cannot revise the arrangement without losing important business.
The financing is therefore not located in one place. It is shared across the chain, but not equally. The customer controls when to release the cash. The supplier carries the receivable and must keep production or service delivery moving. A large customer with access to cash or bank credit may treat the payment date as one of many treasury decisions. A small supplier may experience the same date as a constraint on whether it can accept the next order. This difference is why “the customer will pay eventually” is not a sufficient answer to the supplier's problem.
The diagram's relationships describe a sequence as well as an ownership pattern. The customer receives the value, the supplier issues the invoice, and the payment term defines how long the supplier expects to finance the interval. Settlement converts the receivable into cash. If settlement is late, the time gap grows without creating any additional value for the supplier. It creates an additional funding need.
Why the term belongs to the relationship
The fact that trade credit has a cost does not mean every short term is fair or every long term is abusive. Payment terms reflect the economics of the transaction. The Federal Reserve study describes grocery terms of fewer than ten days where products are perishable. It also reports that sporting-goods suppliers may extend terms for six to nine months because smaller retail customers need to invest in inventory at the beginning of a season. In the first case, the product's limited shelf life makes quick settlement and quick turnover important. In the second, the buyer's seasonal cash cycle is part of the reason the supplier offers time.
A term can therefore serve a real operating purpose. A retailer that must stock goods before a brief selling season may not have enough cash to pay immediately. A supplier that understands this cycle may prefer a longer, predictable term to losing the account or forcing the buyer into more expensive finance. The arrangement becomes dangerous when flexibility is treated as costless, when the supplier cannot price or absorb the additional waiting time, or when the buyer changes the practical payment date after the relationship has already been established.
Competition determines how much of that risk each side can negotiate. If a supplier has many customers, losing one account may be manageable. If one or two customers make up a large share of sales, refusing an extended term can threaten the supplier's revenue more immediately than accepting it threatens the customer's cash position. The Federal Reserve study notes that customers have greater influence over terms when providers deal with a small number of major buyers. Conversely, a supplier with a unique, high-demand product may be able to require customers to follow its terms even if it has few customers.
This is the difference between a term chosen for the transaction and a term imposed by dependence. The words on the invoice may look identical in both cases, but the economic meaning differs. A 60-day term negotiated by two firms with similar alternatives is a shared operating choice. A 60-day term accepted by a small supplier that fears losing its largest customer may be a transfer of working-capital responsibility. The term still matters even if the customer pays on day 60, because the supplier has agreed to wait. If the customer pays on day 90, the transfer has exceeded the agreement.
Imagine two suppliers that each sell to a customer under the same 60-day term. The first has many customers whose receipts arrive at different times. The second depends on one large account and buys materials before that account pays. The written term is identical, but the second supplier has fewer ways to absorb a delay. If the customer pays on day 75, the first supplier may cover the extra period from other receipts; the second may have to ask its material vendor for time or draw on expensive finance. The term does not determine the outcome by itself. It interacts with customer concentration, inventory needs, other cash inflows, and access to alternatives.
The same interaction explains why a supplier can accept a long term deliberately and still become vulnerable later. A predictable seasonal term may be manageable when orders, inventory turnover, and customer receipts follow the expected pattern. A modest change in payment behavior can break that pattern. The supplier has already committed resources, and the customer may have already received the goods, so the supplier cannot easily undo the financing it provided. What looked like a commercial accommodation becomes a larger exposure when the timing assumptions no longer hold.
The EU Payment Observatory's 2024 figures show why the distinction matters at scale. Suppliers reported average B2B payment terms of 43.0 days and average B2B payment periods of 60.3 days. For government-to-business transactions, the reported averages were 55.9 days for terms and 69.8 days for actual payment periods. Across the available observations, longer terms were associated with longer payment periods in 87% of cases. The Observatory's aggregate estimate associated a one-day increase in the agreed term with slightly more than one additional day in the payment period.
These results show a strong pattern, not a rule that mechanically predicts every invoice. The report does not have firm-level microdata connecting each agreed term to each later payment, so the association cannot prove that extending a term causes a particular late payment. Other factors can move both numbers: a weak customer may negotiate a longer term and also be more likely to pay late; a sector may need longer inventory cycles and have different collection practices. The safe conclusion is narrower and more useful: longer terms usually give the supplier less room before the cash becomes available, and they often travel with longer real-world waits.
That boundary matters for both business decisions and public rules. A universal cap may shorten some harmful delays, but it can also ignore a seasonal inventory cycle that both parties understand and have priced. Conversely, a flexible exception can be reasonable in principle while becoming a way for a powerful buyer to shift financing onto a supplier that cannot refuse. Fairness therefore depends on more than the number printed on the invoice: it depends on whether the term is transparent, genuinely agreed, compatible with the supplier's cash cycle, and respected in practice.
The cost of that wait also depends on the supplier's size. The EU evidence finds that large companies are the least punctual payers in 16 of 20 Member States, while micro companies are the most punctual in 13. That does not mean micro firms are less dependent on trade credit. It can mean the opposite. A small firm may pay its own suppliers promptly because it has little bargaining power and cannot risk losing access to materials or services. The same firm may have almost no capacity to absorb a customer that pays later than promised.
This is why the phrase “short-term finance” must not hide who bears the risk. If the buyer's sales slow, the buyer may use the supplier's open account as a buffer. If the supplier's cash reserve is large, the buffer may be affordable. If the supplier is small, concentrated, and already financing inventory, the same delay can force expensive borrowing or a downstream delay. The buyer receives flexibility, but the supplier bears the uncertainty of conversion. The supplier may accept that uncertainty for a higher price, a strategic relationship, or expected volume; it may also accept it because refusing is not a realistic option.
A useful payment term is therefore one that fits the transaction's cash cycle and the parties' ability to carry risk. It should not be judged only by whether the customer pays before the legal deadline. The relevant questions are whether the supplier can fund the wait, whether the term was genuinely negotiable, and what happens if the actual payment period is longer. Once those questions are visible, the invoice can be followed as a moving cash obligation rather than a static promise. The next stage is to trace what happens when the receivable remains outstanding while the supplier's own obligations continue to mature.
