What is Accounts Payable?
Accounts payable (AP) is money you owe to vendors, suppliers, and service providers. It's a liability on your balance sheet representing obligations you'll pay in the near future.
When you receive an invoice with payment terms, the amount becomes accounts payable until you pay it.
Why AP Management Matters
Strategic AP management improves cash flow. Paying too early gives up interest-free financing from suppliers. Paying too late damages vendor relationships and credit terms.
Days Payable Outstanding (DPO) measures how long you take to pay. Higher DPO means you're holding cash longer. But excessively high DPO might indicate payment problems.
Managing Accounts Payable
Use the full payment terms without being late. Take early payment discounts when the math works (2% discount for paying 20 days early = 36% annualized return). Negotiate longer terms with key vendors. Centralize AP to avoid duplicate payments.
Formula
Days Payable Outstanding (DPO) = (Accounts Payable ÷ COGS) × Days in Period
AP Turnover = Total Purchases ÷ Average Accounts Payable
Example
Your ecommerce company manages accounts payable:
- Vendor invoices due: $75,000
- Payment terms: Net 30
- Monthly expenses: $200,000
Days Payable Outstanding = ($75,000 ÷ $200,000) × 30 = 11.25 days
You're paying vendors in about 11 days on average. Extending to the full 30 days would improve cash position by ~$37,500.
