When Payment Terms Make the Supplier Finance the Buyer
Payment timing is not only administration; it allocates financing inside a commercial relationship. Once a supplier has delivered but has not yet been paid, the supplier carries a receivable while the buyer keeps cash. That can be healthy, negotiated trade credit. But when a stronger buyer can impose long terms or pay after the agreed date, working-capital burden can be pushed toward the weaker supplier without ever being described as a loan.
The Brief in One Sentence
The moment value has been delivered but cash has not yet arrived, someone is financing the waiting period; the asymmetry appears when the party with less bargaining power carries that financing burden while the stronger party controls or stretches the clock.
Why It Matters
Late payment is not a marginal accounting nuisance. The European Commission's Payment Observatory reported that more than half of companies experienced difficulties from delayed payments in 2024, with average payment periods above 60 days in both business-to-business and government-to-business transactions. UK government research published in 2025 estimated about £26 billion in late payments outstanding at any given time, affecting more than 1.5 million businesses each year.
The economic consequence is simple: a supplier may have completed the work, paid employees, purchased inputs, financed inventory and incurred tax or logistics costs before receiving the cash that closes the transaction.
Explain It Simply
Imagine you bake 100 loaves for a supermarket. You buy flour today, pay your workers today and deliver the bread today. The supermarket tells you it will pay in 60 days. During those 60 days, your money is inside the supermarket's unpaid invoice instead of in your bank account.
If both sides freely agreed to that arrangement and the price reflects it, that can be normal trade credit. If the supermarket can force the term because you cannot afford to lose the customer, or pays even later than promised, the financing relationship becomes asymmetric.
Evidence Map
- Observed / EU: more than half of companies reported difficulties from late payment in 2024; larger companies were less likely to pay on time; the Commission also identifies power imbalances among the causes of persistent late payment.
- Observed / UK: official research estimates about £26bn outstanding in late payments at any time and more than 1.5m businesses affected each year.
- Observed / Australia: cycle-8 reporting showed a 29-day average common term, but only 68.1% of small-business invoices paid on time; 80% were paid by 37 days and 95% by 56 days.
- Observed / India: qualifying micro and small suppliers are protected by a maximum agreed period of 45 days and penal interest for delay.
- Observed / Japan: reforms effective in 2026 restrict payment instruments and long settlement periods that impose working-capital burden on smaller suppliers.
- Observed / South Africa: in 2025/26 Q2, public departments reported 112,442 invoices worth R10bn paid after 30 days and 95,399 invoices worth R12.4bn still unpaid at quarter-end.
- Inference: payment timing acts as a financing allocation because the unpaid receivable sits on the supplier's balance sheet while the buyer retains cash.
- Uncertain: payment duration alone does not reveal whether the cause is bargaining power, agreed commercial logic, dispute, verification, cash stress or administrative failure.
Three Things That Must Not Be Confused
- Agreed trade credit: the supplier knowingly accepts payment after delivery under a negotiated commercial term.
- Buyer-imposed long terms: the supplier formally accepts a long term but may have little practical bargaining power to refuse it.
- Late payment: the buyer pays after the contractual due date.
All three create a cash interval after delivery, but they are not ethically, commercially or legally equivalent. A serious asymmetry analysis must keep them separate.
Payment Terms Are Also Financing Terms
Suppose a supplier delivers $100,000 of goods today and receives payment 60 days later. Until settlement, the supplier holds a $100,000 receivable. It may need an overdraft, invoice discounting, retained cash or slower payments to its own suppliers to bridge the interval. The buyer, meanwhile, has received the economic value without yet surrendering the cash.
This does not make every 60-day term unfair. It means the term has a financing consequence that should be analysed explicitly rather than hidden inside accounts receivable.
Where Bargaining Power Enters
The asymmetry becomes sharper when losing one buyer would hurt the supplier far more than losing one supplier would hurt the buyer. The supplier may accept a term it dislikes because access to the customer matters more than the financing burden. The European Commission explicitly identifies power imbalances as one root cause of late-payment behaviour, and its 2025 Observatory report found larger companies less likely to pay on time.
That still does not prove abuse in any individual contract. It identifies a mechanism worth testing: the party with greater outside options may be able to shift working-capital burden toward the party with fewer alternatives.
The Same Symptom Can Have Different Causes
South Africa's public-sector data are a useful warning against simplistic explanations. National Treasury lists budget constraints, disputed invoices, missing documentation, system problems, internal-control failures and processing delays among the causes of late and unpaid invoices. A long wait therefore does not automatically prove deliberate extraction by a powerful buyer.
The correct sequence is: observe the delay, identify who carries the cash burden, then investigate why the delay exists and who can change it.
Why Regulation Focuses on Time
Several jurisdictions treat payment duration as more than private administration. India's MSME framework limits the agreed period for qualifying micro and small suppliers to 45 days and imposes compound interest for delay. Japan's reforms effective in 2026 restrict promissory-note and other settlement structures that can keep smaller suppliers waiting beyond prescribed periods. Australia requires large reporting entities to disclose how quickly they pay small-business suppliers.
The common logic is not that every business must pay instantly. It is that time can become a hidden transfer of financing cost when one party has much more power than the other.
Factoring Does Not Automatically Remove the Asymmetry
Invoice finance can release cash earlier, and supply-chain finance can sometimes use a strong buyer's credit quality to lower funding cost. Those can be valuable tools. But they may also leave the commercial term unchanged while moving the financing cost to a bank, factor or supplier discount.
The diagnostic question remains: did the underlying payment relationship improve, or did the system merely find another party to fund the same waiting period?
Sidy’s Synthesis — Follow the Cash After Delivery
The useful analytical move is simple: follow the cash after delivery. Once value has crossed from supplier to buyer, ask where the corresponding cash sits, how long it remains there, who funds the interval and who chose the timing.
This reveals a hidden financing layer inside ordinary commerce. A company can look like a buyer in the commercial contract while behaving partly like a borrower in the cash cycle. Conversely, a supplier can look like a seller while acting partly like a lender until settlement.
The asymmetry becomes decision-relevant when those roles are not chosen on equal terms.
What Would We Need to Know Before Calling It Unfair?
- Was the payment term negotiated before the transaction?
- Could the supplier realistically refuse it without losing a critical customer?
- Is the invoice actually late, or merely within an agreed long term?
- Does the price compensate for the financing period?
- Is payment delayed by dispute, verification or incomplete documentation?
- Does the buyer systematically pay smaller suppliers more slowly?
- Who pays the cost if early-payment finance is used?
Without these answers, a long payment period is a signal to investigate, not proof of exploitation.
What to Monitor Next
- Median and tail payment times, not only averages.
- Agreed terms versus actual payment dates.
- Payment performance by buyer size and supplier size.
- Share of invoices disputed or rejected before payment.
- Cost of overdrafts, factoring and invoice discounting borne by suppliers.
- Use of supply-chain-finance programs and who pays their funding cost.
- Whether new disclosure and maximum-term rules actually shorten cash-conversion cycles.
Remember This
A payment term is also a financing decision. The important question is not only when the invoice is due, but who carries the cash gap between delivery and settlement, at what cost, and with how much bargaining power.
