Trade Credit Insurance: When It Pays Off for Suppliers

Why the question of credit insurance matters now

Every supplier that delivers on invoice gives its customer a loan, usually without collateral. As long as customers pay, nobody notices. When one does not pay, it is not just the profit from the order that is missing but the entire invoice amount, including materials, wages, and VAT that the supplier has already prefinanced.

The risk has grown. Germany’s Federal Statistical Office counted 24,064 corporate insolvency filings in 2025, 10.3 percent more than the year before, and another 6.7 percent more in the first half of 2026. How such defaults travel through the supply chain is described in the article When a customer becomes insolvent. There, trade credit insurance appears as one of the limiting barriers. Here, it is the subject itself.

The guiding question is: When does trade credit insurance pay off for a small or midsize supplier? To answer it, we first clarify the terms, then introduce a mental model with two roles of the insurance, work through an example, review the evidence, and weigh two views. At the end, there is a check you can run before talking to an insurer or broker.

What trade credit insurance is: the key terms

• Trade credit insurance: Insurance that reimburses a supplier for receivables from goods and services delivered on invoice if the customer becomes insolvent or does not pay. In German it is called Warenkreditversicherung or Forderungsausfallversicherung.
• Credit limit: The maximum amount up to which the insurer covers open receivables from a specific customer. Deliveries beyond that are carried by the supplier alone.
• Deductible: The share of the loss that the supplier bears itself. Terms on the market often show values between 10 and 30 percent, depending on the contract and on whether the receivable is disputed.
• Protracted default: The insured event occurs not only on insolvency but also when a customer has not paid for a certain period after the due date. Depending on the provider, this period is roughly two to six months.
• Whole-turnover and single-buyer cover: Under whole-turnover cover, the supplier generally registers all customers with payment terms. Under single-buyer or key-account cover, only selected, usually large customers are insured.

For exports to difficult countries there are also the German federal government’s export credit guarantees; the checklist for the first export order covers them. Insurance differs from factoring in one important respect: it pays only when a loss occurs and does not bring money in earlier. In factoring, the supplier sells its receivables and receives the money immediately. The two are often combined, as the article Factoring: selling receivables to gain liquidity shows.

The mental model: smoothing and monitoring

Most owners see credit insurance only as protection against losses. S. Alex Yang, Nitin Bakshi, and Christopher Chen (2021) showed in a game-theoretic model that it fulfills two different tasks. The distinction helps answer whether the product pays off for a particular business.

The authors explicitly describe monitoring as an information service that goes beyond pure protection: with the insurer’s updated assessment, the supplier can decide better whether to ship an order at all. An analogy makes this tangible. Home insurance pays when the house burns down. Credit insurance pays when a customer defaults, but occasionally sends a letter beforehand saying someone next door is smoking. Anyone who ignores that letter and keeps delivering loses part of the value they are paying for.

Credit insurance sells not just protection but a second pair of eyes on your customers.

What research shows about credit insurance

Yang, Bakshi, and Chen (2021) compare two contract forms. Under cancelable contracts, the insurer may cut or cancel a limit during the term before the goods are shipped. Under noncancelable contracts, the limit stays in place for a fixed period. Their finding: cancelable contracts give the insurer good reason to monitor customers closely, because its assessment directly affects the shipping decision. However, the insurer may use cancelation too aggressively. Noncancelable contracts are preferable when the supplier has poor alternatives and monitoring is cheap for the insurer. The study is a model, not a measurement.

Citing the literature, the authors report that canceled credit limits in the first months of 2009 reached 75 billion euros in total and that suppliers then mostly stopped delivering on credit. According to one estimate, 5 to 9 percent of the drop in world exports during the crisis can be attributed to insurers’ withdrawal. They also refer to an estimate that in the EU, about one in four insolvencies of small and midsize companies is due to customers’ payment defaults.

Koen van der Veer (2015), using data from a large private credit insurer from 1992 to 2006, showed that insured exports noticeably promote trade, and more than the insured amount alone would suggest. In a second study (van der Veer 2019) with the same data, he found the flip side: if the claims ratio between two countries doubles, the share of insured exports falls on average by about 11 percent and the premium rises by about 4 percent. Insurers thus react to losses mainly with less coverage and only secondarily with higher prices.

For Germany, the German Insurance Association (GDV) reports trade credit insurance coverage of 506 billion euros for 2025, more than ever before.

Worked example: expected loss versus premium

Whether insurance pays off purely in numbers is shown by the expected loss. It is the product of three quantities: the probability that a customer defaults, the amount outstanding at the time of default, and the share that remains lost afterward. Banks calculate their credit risks along these lines, and it works the same way for a supplier.

In the example, a wholesaler sells 4 million euros a year on invoice. On average, 500,000 euros are outstanding. Across all customers, it assumes a default probability of 1.5 percent per year, and after an insolvency, 80 percent of the receivable remains lost after the dividend and retention of title. The expected loss is then 500,000 × 0.015 × 0.8 = 6,000 euros a year. A premium of 0.2 percent of turnover would come to 8,000 euros.

Based purely on expected value, the insurance here costs more than the risk. That is true of almost every insurance, because the insurer must cover costs and profit. The decisive line is the third: if the largest customer defaults, 96,000 euros are missing at once. Whether the business can absorb that depends on equity, overdraft line, and margin. At a 4 percent return on sales, the wholesaler would need 2.4 million euros in additional sales to make up for the loss. How heavily a single customer weighs on the business is described in the article Concentration risk.

Two views: partner or fair-weather friend?

The first view sees the credit insurer as a partner. It has access to the payment experience of many suppliers that a single business would never see. Its limits are a constant second opinion, and in a claim it often also handles collection of the receivable. For a business without its own credit department, that replaces a lot of work.

The second view sees it as a fair-weather friend. Insurers cut limits precisely when the situation becomes difficult, often for entire industries at once. The supplier then has to choose between delivering without protection or losing a customer. How consequential the expiry of coverage can be is shown, on a completely different scale, by the Greensill case study, in which a credit insurer did not renew coverage of 4.6 billion dollars.

I consider both views accurate, but of different weight. Cutting a limit is annoying, but it is exactly the monitoring role the supplier is paying for. A canceled limit says that someone with better data considers the customer too risky. A supplier who then switches to prepayment has benefited from the insurance, even if it never pays out. The mistake lies rather in seeing the insurance as a substitute for your own receivables management. It complements it but does not replace it.

When insurance pays off: a five-step check

1. Determine the largest single loss

   How much is outstanding at peak with your largest customer? Calculate how much additional sales would be needed to replace this amount at your margin.

2. Check capacity to absorb

   Compare the amount with equity and unused credit lines. If the default would make the business insolvent, protection is an obvious step.

3. Assess your own credit control honestly

   Do you have credit limits per customer, credit reports, and a fixed dunning process? If not, the insurer’s monitoring role is worth more.

4. Calculate expected loss

   Estimate default probability and loss share from your own defaults over the last five to ten years and compare with offers.

5. Compare terms

   Look at the deductible, the period until protracted default, whether limits can be canceled, reporting duties, and whether customers without a named limit are also covered.

Anyone who already pursues open receivables consistently, as described in Late payment and receivables management, and checks customers before large orders, as in Reading a customer’s balance sheet, needs the monitoring role less. For them, smoothing large single risks matters most, and then cover for the largest customers alone is often enough.

What follows beyond the individual case, and where the limits lie

Credit insurance makes visible a risk that often stays invisible: the credit you give customers without calling it that. Merely asking for a quote forces you to know the open items per customer. The limits of this article: the study by Yang, Bakshi, and Chen is a model, van der Veer’s data come from one insurer and from export business up to 2006, and the worked example uses freely chosen figures.

Conclusion: when trade credit insurance pays off

To the guiding question: trade credit insurance pays off for a small or midsize supplier above all when a single default would endanger the business and when its own ongoing credit assessment is missing. By expected value, it is almost always more expensive than the risk it covers. Its value comes from the two roles described by Yang, Bakshi, and Chen: it smooths large losses, and with every limit it delivers a judgment on the customer. That insurers cut limits in crises restricts the protection, but it is at the same time the information you are paying for.

1. This week: Pull the open items list and note the five customers with the highest peak outstanding amounts.
2. Next week: For each, calculate what their default would mean for equity and liquidity.
3. After that: Obtain two offers with the same assumptions and compare them with cover for the largest customers only.

If you know which default you cannot absorb, you also know what you should insure.
