What Is an Accounts Payable Aging Report?

An accounts payable (AP) aging report is a financial document that categorizes your company’s outstanding bills and invoices by due date. It shows how much money your business owes to each vendor and whether those payments are current or overdue.

The report typically breaks down liabilities into:

Current (0–30 days)
31–60 days past due
61–90 days past due
Over 90 days past due

This tool is essential for monitoring payment obligations, avoiding late fees, and negotiating terms with suppliers.

Why the AP Aging Report Matters for Your Business

Improves Cash Flow Management

By showing when payments are due, it helps businesses forecast and allocate cash appropriately.

Reduces Late Fees and Penalties

Tracking due dates ensures you avoid missing deadlines and hurting your creditworthiness.

Strengthens Vendor Relationships

Consistently paying on time builds trust with suppliers and can lead to better terms or discounts.

Supports Audit and Compliance

AP aging reports are used in audits to validate liabilities and ensure financial accuracy.

Enhances Financial Planning

Provides clear visibility into short-term liabilities, which is essential for budgeting and forecasting.

Sample Format of an Accounts Payable Aging Report

Vendor Name	Total Due	0–30 Days	31–60 Days	61–90 Days	>90 Days
Vendor A	$2,500	$2,500	$0	$0	$0
Vendor B	$3,200	$1,200	$2,000	$0	$0
Vendor C	$5,000	$0	$0	$2,500	$2,500
Total	$10,700	$3,700	$2,000	$2,500	$2,500

This breakdown helps you instantly see which vendors need to be paid soon—or are already overdue.

How to Prepare an Accounts Payable Aging Report

Most accounting software like QuickBooks, Xero, or Sage can generate this report automatically. But here’s how to build it manually:

Step-by-step:

List all open vendor invoices.
Include invoice date, due date, and amount.
Calculate the number of days overdue (Today’s date − Due date).
Group invoices by aging categories.
Sum the amounts in each category.

Tip: Use Excel formulas or templates to automate aging categories and totals.

How to Analyze an Accounts Payable Aging Report

Here’s what to look for when reviewing your AP aging:

Are most balances in the 0–30 day range?
Healthy payment cycle.
Any red flags in the 61–90 or 90+ days columns?
May indicate cash flow issues or poor AP practices.
Are any key vendors repeatedly in the overdue column?
Could damage supplier relationships or credit lines.
Do you have vendor discounts for early payment?
Use this report to plan payments and save money.

Common Mistakes to Avoid

Not reconciling vendor statements regularly
Ignoring small past-due balances that add up over time
Failing to update paid invoices, which can skew the report
