Payables Policy and Stretching Payables Explained

Updated 10 October 2026 · Fact-checked

A payables policy sets when and how a firm pays its suppliers. Stretching payables means paying after the agreed due date to keep cash longer. It gives cheap short-term funds but risks lost discounts, penalties, poor supplier relations and a weaker credit rating. Compare the cost with the benefit before you stretch.

Understand Payables Policy and Stretching Payables

Trade payables are amounts you owe suppliers for goods or services bought on credit. They are a free or low-cost source of short-term finance. A payables policy is the firm's rule on when to pay, which suppliers to pay first, whether to take cash discounts, and who approves delays.

There are three broad stances. A prompt payment policy pays on or before the due date, or within the discount period. A standard policy pays exactly on the due date. A stretching policy delays payment beyond the due date, so days payable outstanding (DPO) rises.

Stretching improves cash and shortens the cash conversion cycle. But it is not free. The supplier may charge late-payment interest, withdraw the cash discount, tighten credit terms, supply less reliably, or raise prices. Banks and rating agencies also see a rising DPO and overdue payables as a sign of liquidity stress, which can hurt the credit rating and raise borrowing cost.

The finance manager must balance two things: the cash saved by paying later, and the cost of that delay. A good policy pays on time where discounts or relationships matter, and stretches only with the supplier's agreement or where the cost is clearly lower than other finance.

Payment efficiency can be improved without damaging relations: negotiate longer credit terms, schedule payments by due date and discount value, use electronic payment, match invoice, order and receipt before paying, and use supplier finance arrangements.

Key rules to remember

Days payable outstanding (DPO)
DPO = (Average trade payables ÷ Credit purchases) × 365
Use cost of goods sold if credit purchases are not given. State the basis you use. Use 360 days if the question says so.
Payables turnover ratio
Payables turnover = Credit purchases ÷ Average trade payables
DPO = 365 ÷ payables turnover. A lower turnover means slower payment.
Cost of foregoing cash discount
Cost = [d ÷ (100 − d)] × [365 ÷ (Credit period − Discount period)]
d is the discount percentage. Credit period is the final due date in days. Simple annual cost.
Cost of foregoing discount when payment is delayed to a later day
Cost = [d ÷ (100 − d)] × [365 ÷ (Days actually taken − Discount period)]
This gives only the implicit cost of the supplier credit when the discount is forgone. Paying later spreads the same discount over more days, so the annual percentage falls. Late-payment penalties, lost goodwill and other costs of stretching are not included and must be added separately.
Cash released by stretching
Cash released = (Daily credit purchases) × (Extra days taken)
Daily purchases = annual credit purchases ÷ 365.

How to solve Payables Policy and Stretching Payables questions

Use this method for any question on payables policy or stretching.

  1. 1Read the data and note credit purchases, credit terms, discount and current days taken.
  2. 2Find the current DPO or payables level, and state the day basis (365 or 360).
  3. 3Calculate the effect of the change in payment days: cash released = daily purchases × extra days.
  4. 4Calculate the cost of stretching: lost discount, penalty interest or higher prices, converted to an annual percentage if asked.
  5. 5Compare this cost with the cost of the alternative source, such as a bank loan or cash credit.
  6. 6Choose the cheaper option and state the decision clearly.
  7. 7Add qualitative points: supplier relations, supply continuity, credit rating, legal terms and reputation.

Quickest way: Compare annual cost with bank rate

When to use it: Use when the question asks whether to take a discount, pay on time or stretch, and gives a bank borrowing rate.

  1. Compute the annual cost of foregoing the discount using the formula with the actual days of payment.
  2. Put it beside the bank interest rate.
  3. If the cost of not paying early is higher than the bank rate, pay early and borrow.
  4. If it is lower, delay payment and use the supplier credit.
  5. If the two are close, treat the decision as nearly neutral and let non-financial risks decide.
  6. Write one line on non-financial risks to earn the extra mark.

Common mistakes in Payables Policy and Stretching Payables

  • Treating stretched payables as free finance.

    No interest appears on the invoice, so students ignore hidden costs.

    Fix: Always list lost discount, penalty, price rise and rating impact, and cost them where numbers are given.

  • Using the wrong denominator for DPO.

    Students use total sales or total purchases by habit.

    Fix: Use credit purchases where given. Otherwise use cost of goods sold and say so.

  • Using the credit period instead of days actually taken in the cost formula.

    Students memorise the standard formula without reading the question.

    Fix: Subtract the discount period from the day on which payment is actually made.

  • Computing the discount cost as just d ÷ (100 − d) with no annualising.

    Students forget to multiply by 365 ÷ days.

    Fix: Always annualise before comparing with a yearly interest rate.

  • Giving only numbers in a descriptive question.

    Students assume payables is purely a calculation topic.

    Fix: Add a short list of benefits, risks and controls to earn written marks.

Worked examples

Example 1

Sundaram Traders has annual credit purchases of ₹7,30,00,000 and pays suppliers in 30 days. It plans to stretch payment to 45 days. Use 365 days. Calculate the additional cash released and state two risks.

Show the solution
  1. Daily credit purchases = ₹7,30,00,000 ÷ 365 = ₹2,00,000.
  2. Extra days = 45 − 30 = 15 days.
  3. Cash released = ₹2,00,000 × 15 = ₹30,00,000.
  4. Risks: suppliers may withdraw discounts or charge late-payment interest, and a longer DPO may weaken supplier relations and credit rating.

Answer: Additional cash released is ₹30,00,000. Risks include lost discounts or penalty and damage to supplier relations and credit rating.

Example 2

Terms are 2/10, net 30. Kaveri Ltd can borrow from a bank at 14% per annum. Use 365 days. (a) Find the annual cost of not taking the discount if it pays on day 30. (b) Find the cost if it stretches to day 60. (c) Advise.

Show the solution
  1. (a) d ÷ (100 − d) = 2 ÷ 98 = 0.020408.
  2. Days = 30 − 10 = 20, so 365 ÷ 20 = 18.25.
  3. Cost = 0.020408 × 18.25 = 0.3724, about 37.24%.
  4. (b) Days = 60 − 10 = 50, so 365 ÷ 50 = 7.3.
  5. Cost = 0.020408 × 7.3 = 0.1490, about 14.90%.
  6. (c) Compare with bank rate of 14%. At day 30 the cost of 37.24% is far above 14%, so taking the discount and borrowing is clearly better than paying on day 30.
  7. At day 60 the cost of 14.90% is only marginally above the 14% bank rate. The gap is about 0.90 percentage points, so the financial decision is nearly neutral. Taking the discount and borrowing is still slightly cheaper, but non-financial risks of stretching, such as penalties, strained relations and credit rating impact, would decide the matter.

Answer: Cost is about 37.24% at day 30 and about 14.90% at day 60. Both are above the 14% bank rate, so paying within the discount period using bank finance is cheaper. At day 60 the advantage is only marginal, so the decision is nearly neutral financially, and the non-financial risks of stretching should decide it.

Exam tips

  • Write the day basis (365 or 360) before calculating, as the question usually fixes it.
  • For a decision question, always compare the cost with the bank rate and state the choice in one sentence.
  • In descriptive answers, split points into benefits, risks and ways to improve efficiency.
  • Show the formula and each step, since step marks are given even if the final figure slips.
  • MCQs often test the direction of effect: stretching raises DPO and shortens the cash conversion cycle.

Practice questions from Payable Management

Payables Policy and Stretching Payables: frequently asked questions

What is stretching accounts payable?

It means paying suppliers after the agreed due date to hold cash longer. It raises days payable outstanding. It may be cheap if the supplier agrees, but costly if it brings penalties or lost goodwill.

What are the main risks of stretching payables?

The main risks are lost cash discounts, late-payment charges, stricter credit terms, supply disruption and higher prices. It can also lower your credit rating and make bank finance costlier.

How can a firm optimise accounts payable days?

Negotiate longer terms, pay according to due dates and discount value, automate payments and invoice matching, and use supplier finance options. The aim is the longest period that does not harm relations or cost more than other finance.

Is a higher DPO always good?

No. A higher DPO releases cash, but if it comes from late payment it signals stress and risks supplier action. It is good only when agreed terms are longer or the cost is lower than alternatives.
