Payables Management is about how smartly a business manages the money it owes to its suppliers. Think of it as the flip side of receivables — instead of collecting money, you're deciding when to pay it. Done right, trade credit is essentially free short-term finance. Done wrong, it costs you hidden interest or ruins supplier relationships.
Trade creditors are suppliers who deliver goods now and collect later — say in 30, 45, or 60 days. This delay is called trade credit, and it funds your working capital without any explicit interest charge. The key metric is the Average Payment Period (APP), also called Creditor Days: APP = (Trade Payables ÷ Credit Purchases) × 365. A higher APP means you're holding cash longer (good for liquidity), but pushing it too far — called stretching payables — risks late-payment penalties, loss of discounts, and damaged supplier trust. ICAI distinguishes between legitimate credit extension and unethical stretching.
The most exam-tested concept in payables is the cost of forgoing a cash discount. Suppliers often offer terms like "2/10, net 45" — meaning: pay within 10 days and get 2% off, or pay the full amount by day 45. To decide, calculate: Cost of forgoing = [d ÷ (100 − d)] × [365 ÷ (Net period − Discount period)], where d is the discount percentage. If this annualised cost exceeds your borrowing rate (e.g. bank overdraft at 12%), take the discount — it's cheaper to borrow from the bank. If the cost is lower than your borrowing rate, skip the discount and keep the free credit.
Payables also directly affect the Cash Conversion Cycle (CCC): CCC = Inventory Days + Receivable Days − Payable Days. Increasing your payable days reduces CCC, which means less working capital tied up and lower financing costs. This is why well-run companies negotiate longer payment terms with suppliers. This topic is frequently tested as a 4–6 mark combined theory + numerical question in Paper 6 — expect APP calculations, discount decisions, or CCC-linked working capital problems.
