A Customer Demands Extended Payment Terms

The scenario

A large or strategically important customer wants longer to pay. They are pushing your standard 30-day terms out to 60 or 90 days, framing it as 'aligning with our processes' or 'standard for suppliers our size', and implying — sometimes openly — that continuing to win their work depends on you saying yes. The volume is attractive, but the cash-flow cost of funding them for an extra month or two is real.

This is a negotiation, not a foregone conclusion. Extended terms are effectively you lending the customer money interest-free, and that lending has a cost. The question is whether the relationship is worth that cost, and if so, what you can secure in return so the deal still works for you.

What's really going on

A demand for extended terms is sometimes a genuine alignment request from a large buyer with standardised processes, and sometimes a leverage play that uses the promise of volume to push the cost of their working capital onto you. Either way, the economics are the same: every extra day they take to pay is a day you finance their business, and across a large account that adds up to a meaningful, often hidden, cost.

It can also be an early warning. A customer who suddenly needs much longer to pay may be under cash-flow pressure of their own — worth noting even if the request looks routine. The right response treats this as a commercial trade: if you give something on terms, you should get something back, whether that is volume commitments, better pricing, a deposit, or security. Conceding for nothing trains the customer to keep pushing.

Your options

• Cost the extension. Work out what financing the customer for the extra days actually costs you before deciding.
• Trade, don't concede. Offer extended terms only in exchange for volume, pricing, a deposit, or security.
• Offer an alternative. An early-payment discount or a milestone structure can meet the customer's cash needs without blanket-extending terms.
• Tighten protections. If you agree, document the new terms clearly and consider a guarantee or retention of title.
• Hold your terms. Where the cost outweighs the relationship, decline firmly and professionally.

Recommended approach

Treat it as a commercial negotiation, not a loyalty test. First, cost the extension honestly — funding a large account for an extra 30 or 60 days has a real price that should inform your answer. Then, if the relationship justifies engaging, trade rather than concede: agree to longer terms only in return for something of value, such as guaranteed volume, better margins, a deposit on each order, or security like a guarantee or retention of title. Often a smarter structure — an early-payment discount, or milestone billing — meets the customer's underlying cash need without you blanket-funding them.

Whatever you agree, document the revised terms clearly so there is no ambiguity later. If you decline, do it firmly and professionally; a customer who only stays while you fund them interest-free was never as profitable as the volume suggested. For setting and defending sound trading terms, the Academy lesson library is a good reference, and Merion's credit-control resources can help you frame the conversation.

What to avoid

Do not concede extended terms for nothing — giving away your working capital with no return trains the customer to keep pushing and erodes the margin on the account. Avoid agreeing without documenting the new terms, because verbal arrangements unravel exactly when you need them. Never ignore the warning sign in a sudden demand for much longer terms; it can signal the customer's own cash-flow strain. This is general guidance, not legal advice. If you add security or guarantees as part of the deal, have those documents reviewed before relying on them.
