Extended payment terms: the hidden cost that procurement never prices

Q: What is a healthy DPO range?

The median DPO for large US non-financial companies is approximately 57 days. Top-quartile performers reach around 67 days. Extending beyond 90 days without an SCF program increasingly shifts financing costs back to the buyer through higher prices.

Most procurement teams treat payment terms as a working capital lever. Extend DPO by 15 days, free up cash, improve the balance sheet. The logic appears straightforward, but it assumes the supplier absorbs the financing cost. The evidence suggests otherwise: suppliers price the cost of delayed payment back into unit prices, and the net effect can be negative for buyers who extend terms without a structured program.

Terms some buyers now demand (days)

A 2024 study in the International Journal of Production Research found that systematic payment term extensions are generally a zero-sum or even negative-sum game, because suppliers pass on the costs of increased financing burdens through higher prices [Source]. For every one-day increase in DPO, non-SCF buyers saw a 0.036% performance decrease. The cash freed by extending terms was offset — and sometimes exceeded — by rising input costs.

The pricing pass-through that finance never sees

When a buyer extends payment terms from Net 30 to Net 90, the supplier faces a 60-day working capital gap. A supplier with a 10% cost of capital effectively loses 1.64% of the invoice value in financing costs. In competitive commodity markets where suppliers operate on 3-5% margins, this cost cannot be absorbed. It is passed through.

Research cited in supply chain finance guidance indicates that extending terms by 15 to 30 days can lead suppliers to increase prices by 5% to 8% [Phoenix Strategy Group]. Even a 1% price increase can negate the working capital benefit of a 30-day extension. The P&L impact is invisible because it shows up as a higher unit price, not a line item called "cost of delayed payment."

"Extending terms by 15 to 30 days can lead suppliers to increase prices by 5% to 8%, potentially offsetting the financial benefits of the extension."

The SCF alternative: when longer terms actually work

Supply chain finance changes the equation. In an SCF program, a third-party financier pays the supplier early (within days of invoice approval) at a discount based on the buyer's credit rating. The buyer repays the financier at the extended due date [J.P. Morgan]. The supplier gets near-immediate payment. The buyer extends DPO. The financier collects the spread.

The same 2024 study found that SCF buyers saw a 0.103% performance increase per incremental day of DPO — a reversal of the non-SCF outcome [T&F, 2024]. The mechanism: SCF replaces the supplier's expensive financing (their own borrowing cost or factoring rate) with the buyer's cheaper financing, so the supplier has no reason to raise prices.

Unilateral extension (no SCF)

Terms extended from Net 30 to Net 90 without financing program. Supplier absorbs 60 days of additional working capital cost.

Outcome: supplier raises prices 5-8%, net buyer benefit negative

Extension with SCF program

Terms extended to Net 90, but financier pays supplier in 3-5 days. Supplier pays small discount based on buyer's credit rating.

Outcome: buyer improves DPO by 60 days, supplier gets paid faster, net positive

Why most procurement teams get this wrong

The most common failure is structural: procurement negotiates payment terms, finance counts the DPO improvement, but nobody tracks the unit price impact. The purchasing team benchmarks supplier pricing against competitors who also have extended terms, so the inflated baseline becomes the new normal. The cost is invisible because it is compared against an equally inflated market.

According to Hackett Group data, the median DPO for the 1,000 largest US non-financials was approximately 57 days in 2017, with top-quartile performers reaching around 67 days [Supply Chain Dive]. During the COVID-19 pandemic, firms extended terms further — large firms in Europe added 7 days and US firms added 10 days on average [ScienceDirect, 2023]. By late 2024, some buyers were demanding 90 to 120-day terms from leverage and transactional suppliers.

What good looks like: pricing terms before payment terms

Organizations that manage payment terms effectively follow a sequence: lock unit pricing first, negotiate payment terms second. A buyer who negotiates Net 30 pricing and then offers a Net 90 extension with SCF captures the working capital benefit without paying for it in higher prices.

Best practice separates suppliers by strategic importance. Strategic suppliers receive shorter terms (Net 30-45) and are integrated into SCF programs with low discount rates. Leverage suppliers handle Net 60-90 through SCF where the discount is transparent. Transactional suppliers operate at standard terms with automated early-pay options [Phoenix Strategy Group].

What this means in practice

Measure the full cost of extension before changing terms. Calculate the supplier's implied financing cost and model how much of it returns as price increases. Use the supplier's cost of capital, not yours. If you cannot model it, do not extend terms.
Implement SCF before extending beyond Net 60. Without a financing program, extending beyond 60 days shifts financing costs to suppliers who will return them in pricing. The academic literature suggests the breakeven for unilateral extension is around 45-60 days.
Negotiate unit price before payment terms in every sourcing event. Lock the price with a standard term baseline (Net 30), then discuss extension as a separate commercial lever. Do not bundle them.
Segment suppliers by financing need, not just spend. A small strategic supplier with weak banking access benefits more from SCF than a large supplier with strong cash reserves. Tailor the program to the supplier's situation, not the buyer's DPO target.
Track unit price trends before and after term changes. If prices rise 5% after extending terms by 30 days, the working capital gain is an illusion. Build the tracking into quarterly business reviews with category managers.

Does extending payment terms actually save money?

For buyers without supply chain finance, extending payment terms rarely saves money in net terms because suppliers embed their increased financing costs into unit prices. Studies show a 15-30 day extension can trigger 5-8% price increases.

What is supply chain finance (SCF)?

SCF is a buyer-led program where a third-party financier pays suppliers early at a discount based on the buyer's credit rating, while the buyer repays at the extended due date. It allows buyers to extend DPO without delaying cash to suppliers.

Do suppliers prefer longer payment terms?

Some suppliers prefer longer terms when paired with SCF because they access cheaper financing than their own bank lines would provide. But when terms are extended without an SCF program, suppliers are forced to raise prices or reduce service levels.

What is a healthy DPO range?

The median DPO for large US non-financials is approximately 57 days. Top-quartile performers reach around 67 days. Extending beyond 90 days without an SCF program increasingly shifts financing costs back to the buyer through higher prices.
