A Supply-Chain Payment Delay Hits Your Account

The scenario

Your invoice is overdue and the customer's explanation is that they are waiting to be paid by their customer further up the chain. 'As soon as the head contractor pays us, you'll be paid' — a familiar refrain in construction, logistics, manufacturing and any tiered supply arrangement. The implication is that your payment is contingent on a transaction you are not party to and have no control over.

The instinct is to accept it as just how the industry works. But unless your contract genuinely makes payment to you conditional on them being paid, their cash-flow problem up the chain is not your problem to absorb. You contracted with them, and their obligation to you usually stands on its own feet.

What's really going on

'Pay-when-paid' is being asserted informally even where the contract does not provide for it. Your customer is treating their own receivable risk as yours to carry, which conveniently shifts the cost of a delay further up the chain onto you. In some industries, contractual pay-when-paid or pay-if-paid clauses are limited or unenforceable under security-of-payment legislation — so the explanation may not even reflect the legal position.

Underneath, the customer may simply be using your money as a buffer: holding your payment while they wait, because it eases their cash flow at your expense. It can also flag that the customer is thinly capitalised and entirely dependent on upstream payment to meet downstream obligations — a fragility worth noting. The key point is that, unless your contract clearly ties your payment to theirs, their obligation to you is independent, and you are entitled to hold them to it.

Your options

• Check your contract. Confirm whether your terms actually make payment conditional on the customer being paid — most do not.
• Hold them to their obligation. Restate, politely but firmly, that your contract is with them and your invoice is due regardless of the upstream position.
• Use any statutory protection. In some industries, pay-when-paid clauses are limited or void under security-of-payment law.
• Tighten future terms. Require deposits or shorter terms on exposed work in extended chains.
• Escalate the overdue balance. If the delay drags on, treat it as the overdue debt it is.

Recommended approach

Check your contract first to confirm what it actually says — in most cases your customer's obligation to pay you is not conditional on them being paid, and once you know that, you can hold them to it. Respond politely but firmly: your agreement is with them, the invoice is due on its terms, and the upstream position is theirs to manage, not yours to fund. In industries with security-of-payment regimes, informal pay-when-paid may carry even less weight than the customer suggests, so it is worth checking that protection.

Going forward, protect yourself in long chains with deposits or shorter terms on exposed work, and treat heavy reliance on upstream payment as a sign of customer fragility worth watching. If the delay persists despite a clear, independent obligation, escalate it like any overdue debt — you can refer the debt with the contract and account history attached. The Academy lesson library covers structuring terms to reduce supply-chain exposure.

What to avoid

Do not accept 'we'll pay when we get paid' as binding just because it is common — check whether your contract actually says so, because usually it does not. Avoid carrying the customer's upstream receivable risk for free; their cash-flow gap further up the chain is not yours to absorb. Never ignore the warning in a customer who is wholly dependent on upstream payment to meet their obligations to you — it can signal fragility. This is general guidance, not legal advice. Pay-when-paid rules vary by industry and jurisdiction, so take advice where security-of-payment legislation may apply.
