Can You Help Us Negotiate Better Payment Terms With Suppliers?

Supplier payment terms are one of the most underutilised levers in working capital management. Many UK SMEs accept the terms initially offered by suppliers without question — often paying within 14 or 30 days when 45 or 60 days might be readily available with a straightforward conversation. A fractional Finance Director brings both the commercial expertise to identify where extended terms are achievable and the negotiation experience to secure them without damaging critical supply relationships.

Why Supplier Payment Terms Are a Working Capital Tool

Days Payable Outstanding (DPO) is one of the three components of the cash conversion cycle. Every additional day of payment terms granted by a supplier is a free, unsecured loan for that extra day — the supplier is effectively financing a portion of your working capital at no cost. Extending DPO from 30 days to 60 days on £500,000 of annual supplier spend releases approximately £41,000 of working capital permanently, simply by taking longer to pay the same bills.

This is not about delaying payment unfairly or squeezing suppliers. It is about aligning payment terms with what is commercially reasonable, consistently applied, and mutually agreed. Many suppliers will readily extend terms to a customer they trust, especially when asked professionally and accompanied by a commitment to pay reliably within the agreed terms.

The Current Landscape for UK Business Payment Terms

The UK Prompt Payment Code and various voluntary initiatives have put pressure on larger businesses to pay smaller suppliers promptly. However, the commercial reality for most SMEs is that the terms on offer from their suppliers remain negotiable, and most businesses simply never ask. A fractional FD will conduct a supplier payment terms audit — mapping current terms against what is typical in the relevant industry — to identify where the biggest opportunities lie.

Preparing for Supplier Payment Negotiations

Effective negotiation of supplier payment terms requires preparation. A fractional Finance Director will approach the process systematically, building the case for extended terms on a supplier-by-supplier basis before any conversation takes place.

Prioritising Suppliers by Working Capital Impact

Not all suppliers are worth the same effort. A fractional FD will segment the purchase ledger by annual spend, current payment terms, and the potential working capital benefit of extending terms. The highest-priority negotiations are those where annual spend is largest and current terms are shortest — typically the top ten or twenty suppliers by spend, which in most businesses account for the majority of total purchase ledger outflow.

Understanding What Suppliers Value

The most successful supplier term negotiations offer something in return. A fractional FD will identify what matters most to each key supplier — whether that is payment reliability, volume commitment, a long-term supply agreement, or the removal of early payment pressure — and build a negotiation position that creates genuine value for both parties. A supplier who knows they will be paid predictably at 60 days may well prefer that to being chased intermittently at 30 days with disputed invoices in between.

The Negotiation Approach

A fractional Finance Director will either lead supplier payment negotiations directly or coach the procurement and finance teams to do so effectively. The approach typically follows this sequence:

1. Review the existing supplier agreement: Understand what payment terms are already contractually agreed versus what is simply conventional practice.
2. Prepare the business case: Quantify the working capital impact of extended terms and frame the request in terms of long-term relationship value.
3. Open the conversation at the right level: Payment terms discussions are most effective at commercial or finance director level, not through accounts payable.
4. Propose a specific term: Asking for 60 days is more effective than asking "can we have better terms?" — clarity accelerates the conversation.
5. Offer something in return: Reliable payment, volume commitment, or removal of payment-related admin for the supplier can often unlock extended terms without price concession.
6. Document and implement: Any agreed extension should be confirmed in writing and implemented immediately in the purchase ledger and payment run processes.

"The best supplier negotiations are those where both parties leave better off — the buyer with extended terms, the supplier with a more predictable, reliable customer. A fractional FD structures the conversation to create that outcome."

Balancing Extended Terms Against Supplier Relationships

There are situations where pushing for extended terms is not appropriate. Micro-businesses and sole traders who are themselves working capital-constrained should not be pressured into extended terms that create hardship — quite apart from the reputational and ethical considerations, it is also contrary to the spirit of the UK's voluntary payment codes. A fractional FD will distinguish between the large, well-capitalised suppliers where extended terms are entirely reasonable and the smaller suppliers where prompt payment is the right commercial and ethical approach.

For key suppliers where extended terms are not available, alternative approaches such as supply chain finance or dynamic discounting may achieve a similar working capital benefit while actually improving the supplier's cash position — a genuinely mutual outcome.

Maintaining Terms Once Negotiated

Negotiated payment terms only deliver their working capital benefit if the business actually pays within the agreed terms — not early and not significantly late. A fractional FD will work with the finance team to ensure payment runs are structured to maximise use of available terms: typically running payments on the last day within terms rather than ad hoc throughout the month. This payment run discipline alone can release significant cash in businesses currently paying suppliers ahead of schedule by default.

Combined with improvements on the customer collections side — such as reducing debtor days — extended supplier terms are a powerful component of a comprehensive cash conversion cycle improvement programme.
