How to Extend Payment Terms Without Hurting Supplier Cash Flow

Learning how to extend payment terms without hurting supplier cash flow starts with separating two dates: when the buyer settles and when the supplier receives liquidity. A buyer may want to move from 30 to 60 days to preserve cash, while a supplier may need funding much sooner to pay wages, purchase materials, or fulfil new orders. 

Those objectives are not necessarily incompatible. Financing can allow an eligible supplier to receive cash before the buyer’s final settlement date. The challenge for treasury and procurement is to choose a structure with acceptable costs, clear terms and a credible option for suppliers that cannot or do not want to participate. 

Why extended payment terms put supplier cash flow under pressure 

Longer terms can improve the buyer’s days payable outstanding and reduce short-term funding needs. For example, extending actual settlement by 30 days across £20 million of eligible annual spend could increase average cash retained by approximately £1.64 million, assuming consistent purchasing. 

That liquidity gain is not the same as annual profit. It also creates a longer receivables period for suppliers. A supplier may respond by borrowing more, discounting invoices, increasing prices, reducing inventory or prioritising customers that pay sooner. These effects can return to the buyer through higher costs or weaker supply resilience. 

Before changing terms, establish current contractual dates, actual payment behaviour and the proportion of spend that is genuinely eligible. ETR Digital’s cash conversion cycle calculator provides a useful starting point. 

Compare the main payment and financing options 

No single arrangement will suit every supplier. Treasury should compare the effect on buyer cash, supplier liquidity, cost allocation and operational effort. 

Financing-supported structures are particularly relevant when the buyer wants to preserve cash without requiring a supplier to wait until maturity. Working Capital Notes™ are digital negotiable instruments that can support financeable payment obligations and structured settlement workflows. 

Model a 30-day to 60-day extension 

Assume a £100,000 eligible invoice previously due on day 30. Under a financing-supported 60-day arrangement, the supplier elects to receive funding on day 5, and the buyer settles the financing obligation on day 60. 

• Day 0: The buyer approves the eligible invoice or trade obligation. 
• Day 5: A participating financier provides optional early liquidity. 
• Day 30: The supplier has already received funds instead of waiting for the original payment date. 
• Day 60: The buyer settles the obligation at the agreed maturity. 

At an illustrative simple annualised rate of 8%, financing £100,000 for 55 days would cost approximately £1,205: 

£100,000 × 8% × 55 ÷ 365 = £1,205 

If the supplier pays the entire charge, its net receipt would be approximately £98,795 before other fees. The buyer could subsidise part of the cost, but that reduces the buyer’s net benefit. Treasury should therefore compare the annual value of cash retained with financing charges, programme fees and any supplier repricing. 

Early funding must remain a genuine commercial option. If a supplier declines or is ineligible, it may still wait until day 60. A financing offer alone does not guarantee that supplier cash flow is protected. 

Segment suppliers before extending payment terms 

A uniform policy can create disproportionate pressure. Segment suppliers using four factors: 

• Financial resilience: Cash reserves, leverage, and access to affordable funding. 
• Working capital intensity: The amount of cash committed before payment is received. 
• Operational criticality: The effect of delayed or reduced supply on the buyer. 
• Implementation readiness: The supplier’s ability to complete onboarding and use the chosen process. 

Financially resilient suppliers may accept conventional extensions. Suppliers with material funding needs may value optional finance. Critical or vulnerable suppliers may need existing terms, a buyer subsidy, or a tailored arrangement. Procurement should lead the relationship assessment while treasury tests the economics. 

Implement extended payment terms in six steps 

1. Define the liquidity objective: Quantify the desired change in actual settlement timing and cash retained. 
2. Establish the baseline: Reconcile contracts, invoice triggers, approval times, and actual payment performance. 
3. Segment suppliers: Identify where extensions, financing, or unchanged terms are most appropriate. 
4. Evaluate providers and technology: Compare funding capacity, pricing, eligibility, integration, controls and onboarding. 
5. Confirm the framework: Document contractual dates, financing maturity, cost allocation and legal and accounting treatment. 
6. Pilot and measure: Test with a controlled supplier group before expanding the programme. 

Supplier communication should explain whether participation is optional, how charges are calculated, what documentation is required and what happens if finance becomes unavailable. 

Protect fair payment and programme resilience 

Extended terms should be clear, agreed and documented. The UK Fair Payment Code criteria emphasise clear and fair terms, written agreements before work begins and collaborative relationships with suppliers. Qualifying businesses should also assess applicable payment-practices reporting requirements. 

Treasury should plan for reduced credit limits, higher financing rates or provider withdrawal. It should also retain a workable route for suppliers that decline financing. Poor invoice data, approval delays and disputes can prevent early funding even when a programme is available, so accounts payable performance remains critical. 

Measure the combined outcome 

Track actual DPO, average cash retained, annual funding value, programme charges and changes in borrowing. For suppliers, monitor the timing and net amount of early funding, participation, complaints and pricing changes. Operational measures should include approval-to-funding time, errors, onboarding time and delivery performance. 

A successful programme improves buyer liquidity without creating disproportionate supplier costs or supply chain risk. 

Frequently asked questions 

Can suppliers be paid early when buyers have 60-day terms 

Yes, if an appropriate financing structure allows a participating provider to fund an eligible supplier before the buyer’s maturity date. Availability depends on pricing, eligibility, documentation, and applicable law. 

Who pays for early supplier financing 

The supplier, buyer, or both may bear the charge. The chosen allocation should reflect the value each party receives and the risk that excessive supplier costs lead to repricing or low participation. 

Do longer payment terms always improve working capital 

Longer actual settlement generally increases accounts payable, but the net economic outcome depends on financing costs, supplier pricing, participation, and operational risk. Cash released and annual savings should be reported separately. 

Extend payment terms with a complete financial view 

To extend payment terms without hurting supplier cash flow, treasury must model more than the buyer’s final payment date. The right arrangement combines realistic liquidity value, optional and affordable supplier finance, clear contractual treatment and supplier segmentation.
