Accounts Payable Management Basics for CMA Intermediate

Updated 10 October 2026 · Fact-checked

Accounts payable management is the planning and control of amounts you owe suppliers for goods and services bought on credit. Its aim is to use trade credit as cheap finance without hurting supplier relations or losing discounts. In numbers, payables deferral period = average payables ÷ credit purchases × 365, and it reduces the cash conversion cycle.

Understand Accounts Payable Management Basics

Trade payables (also called accounts payable or sundry creditors) are amounts a business owes suppliers for goods or services bought on credit. They are a current liability. Because the supplier lets you pay later, payables work as a free, spontaneous source of short-term finance.

Payable management means deciding how much credit to take, when to pay, and whether to take a cash discount. The finance manager must balance two things. Paying late keeps cash in the business longer. Paying too late can cost you discounts, damage your credit rating, and lead to stricter terms or supply disruption.

The main objectives are: (1) use trade credit as a low-cost source of working capital; (2) pay on time to keep supplier goodwill and a good credit standing; (3) take cash discounts when they are worth more than the cost of the money used; (4) keep enough liquidity to meet each due date; (5) keep track of dues and avoid penalties, interest or disputes.

Payables sit inside working capital. Net working capital = current assets − current liabilities, so a larger payables balance means less money is needed to fund stock and debtors. In the operating cycle, you hold stock, sell on credit, then collect cash. Payables let you delay your own payments during this period. The cash conversion cycle (CCC) = inventory period + receivables period − payables deferral period. A longer payables deferral period shortens the CCC and cuts the funds you need to finance.

Trade credit is not always free. If a supplier offers a cash discount for early payment and you skip it, the discount you lose is a real cost of that credit. Compare that cost with your bank borrowing rate before you decide to delay payment.

Key rules to remember

Payables deferral period (PDP)
PDP = Average trade payables ÷ Credit purchases per day = (Average payables ÷ Annual credit purchases) × 365
Use credit purchases, not total purchases. If only cost of goods sold is given, state that you are using it as a proxy for purchases. Use 360 days if the question says so.
Payables turnover ratio
Payables turnover = Annual credit purchases ÷ Average trade payables
PDP = days in year ÷ payables turnover. Average payables = (opening + closing) ÷ 2 when both are given.
Cash conversion cycle
CCC = Inventory period + Receivables period − Payables deferral period
Operating cycle = inventory period + receivables period. CCC = operating cycle − PDP.
Net working capital
NWC = Current assets − Current liabilities
Higher payables raise current liabilities and lower NWC for the same current assets. This means less funding is needed.
Cost of foregoing a cash discount (approximate, annualised)
Cost = [Discount % ÷ (100 − Discount %)] × [365 ÷ (Credit period − Discount period)] × 100
Example terms: 2/10 net 30. Covered in detail in the cash discount topic.

How to solve Accounts Payable Management Basics questions

Use this method for any question on payable management, whether it is theory or numerical.

  1. 1Identify what is asked: meaning, objectives, a ratio, the effect on the cash cycle, or a decision on taking credit.
  2. 2For theory, define trade payables first, then list objectives and importance, and finish with the risks of stretching payables.
  3. 3For numbers, pick the right base: credit purchases for payables ratios. Check whether opening and closing balances are given so you can take the average.
  4. 4Compute payables turnover or PDP using the stated number of days (365 or 360).
  5. 5Compute the other cycle components, then CCC = inventory period + receivables period − PDP.
  6. 6If a change is proposed, such as a longer credit period, recompute the CCC and the funds needed. Funds saved = change in days × purchases per day.
  7. 7Write one line of interpretation: a shorter CCC means less working capital financing is needed, but check supplier goodwill and discount loss.
  8. 8State the final answer with units (days or ₹).

Quickest way: Three-line CCC check

When to use it: Use this in MCQs and in the first pass of a numerical question where PDP and CCC are required.

  1. Find purchases per day = annual credit purchases ÷ 365 (or 360).
  2. PDP = average payables ÷ purchases per day.
  3. CCC = inventory days + debtor days − PDP. If the payables period rises by x days, CCC falls by x days, and funds needed fall by x × purchases per day.

Common mistakes in Accounts Payable Management Basics

  • Using sales or total purchases instead of credit purchases to compute PDP.

    Students copy the debtor days pattern or ignore the word 'credit'.

    Fix: Payables relate to credit purchases. Use cost of goods sold only when purchases are not given, and say so.

  • Adding PDP to the operating cycle instead of subtracting it.

    All three periods look similar and students add them together.

    Fix: Remember that payables are a source of finance, so they reduce the cycle: CCC = inventory + receivables − payables.

  • Saying delaying payments is always good.

    Students focus on cash held and forget the costs.

    Fix: Mention lost discounts, interest or penalties, a weaker credit rating and risk to supplies. Delay is useful only if its cost is lower than other sources.

  • Using closing payables when the question gives opening and closing balances.

    Students rush and pick one figure.

    Fix: Use the average of opening and closing unless the question tells you to use the closing balance.

  • Treating trade credit as having no cost at all.

    Payables do not carry interest, so they seem free.

    Fix: Say it is free only if no discount is lost. If a discount is available, compare its annualised cost with the bank rate.

Worked examples

Example 1

Prasad Traders had opening trade payables of ₹3,80,000 and closing trade payables of ₹4,20,000. Credit purchases for the year were ₹29,20,000. Taking 365 days in a year, calculate (a) the payables turnover ratio and (b) the payables deferral period.

Show the solution
  1. Average payables = (3,80,000 + 4,20,000) ÷ 2 = 8,00,000 ÷ 2 = ₹4,00,000.
  2. Payables turnover = 29,20,000 ÷ 4,00,000 = 7.3 times.
  3. PDP = 365 ÷ 7.3 = 50 days.
  4. Check: purchases per day = 29,20,000 ÷ 365 = ₹8,000. PDP = 4,00,000 ÷ 8,000 = 50 days.

Answer: Payables turnover is 7.3 times and the payables deferral period is 50 days.

Example 2

Shree Textiles has an inventory period of 60 days and a receivables period of 45 days. Its payables deferral period is 30 days. Annual credit purchases are ₹36,50,000 (365 days). The firm negotiates with suppliers to extend the payables period to 45 days. Calculate the cash conversion cycle before and after the change, and the reduction in funds needed.

Show the solution
  1. Before: CCC = 60 + 45 − 30 = 75 days.
  2. After: CCC = 60 + 45 − 45 = 60 days.
  3. Purchases per day = 36,50,000 ÷ 365 = ₹10,000.
  4. Reduction in funds needed = 15 days × ₹10,000 = ₹1,50,000.
  5. Interpretation: the firm needs ₹1,50,000 less working capital finance, provided supplier terms and goodwill are not harmed.

Answer: CCC falls from 75 days to 60 days, and funds needed fall by ₹1,50,000.

Exam tips

  • For a 'discuss' question, structure the answer as meaning, objectives, benefits and risks. This earns step marks even without numbers.
  • In MCQs, check whether the question wants the effect on CCC. A longer payables period always shortens CCC when other periods are unchanged.
  • Write the formula before substituting. Show average payables and purchases per day as separate lines.
  • State the day basis (365 or 360) that you used, so a marker can follow your working.
  • Add a one-line interpretation to every numerical answer. ICMAI expects comment, not just the figure.

Accounts Payable Management Basics: frequently asked questions

What is accounts payable management?

It is the planning and control of amounts owed to suppliers on credit purchases. The aim is to use trade credit as cheap finance while paying on time and taking worthwhile discounts.

How does the payables deferral period affect the cash conversion cycle?

CCC = inventory period + receivables period − payables deferral period. A longer payables deferral period reduces the CCC, so the business needs less working capital finance.

Is trade credit really a free source of finance?

It is free only if you lose no cash discount and pay within the agreed period. If you skip an early payment discount, the lost discount is an implicit cost that you should compare with your bank borrowing rate.

Should I use total purchases or credit purchases for PDP?

Use credit purchases, because only those create payables. If the question gives only cost of goods sold or total purchases, use that figure and state your assumption.
