Accounts payable represent money your business owes to vendors, suppliers, or service providers.
Accounts payable (AP) is one of the most important short-term liabilities on a company’s balance sheet. It represents money a business owes to suppliers and vendors for goods and services received on credit. Managing AP effectively is crucial for cash flow, financial health, and maintaining good supplier relationships.
This guide explains accounts payable in plain language, with examples, formulas, and practical insights for businesses and investors.
What Is Accounts Payable?
Accounts payable (AP) is the amount a company owes to its suppliers or creditors for purchases made on credit. It’s recorded as a current liability on the balance sheet because payment is usually due within 30–90 days.
Simple Example:
- A business buys office supplies worth $5,000 on credit.
- Until the bill is paid, the $5,000 appears under Accounts Payable on the balance sheet.
How Accounts Payable Works
When a company receives goods or services before making payment, the transaction creates a liability.
Accounting Journal Entry (when purchasing on credit):
Debit: Office Supplies (Asset) .......... $5,000
Credit: Accounts Payable (Liability) .... $5,000
Journal Entry (when payment is made):
Debit: Accounts Payable (Liability) ..... $5,000
Credit: Cash/Bank (Asset) ............... $5,000
This process ensures accurate financial reporting and cash flow tracking.

Key Account Payable Metrics
1. Accounts Payable Turnover Ratio
This ratio measures how quickly a business pays its suppliers.
Formula:
AP Turnover = Total Supplier Purchases ÷ Average Accounts Payable
Example:
- Purchases from suppliers = $600,000
- Beginning AP = $100,000
- Ending AP = $140,000
- Average AP = ($100,000 + $140,000) ÷ 2 = $120,000
AP Turnover = 600,000 ÷ 120,000 = 5
This means the company pays suppliers 5 times per year.
2. Days Payable Outstanding (DPO)
Shows the average time (in days) a company takes to pay its suppliers.
Formula:
DPO = (Average Accounts Payable ÷ Cost of Goods Sold) × 365
