The best way to understand the health of your accounts payable is to run an aging report. Accounts payable aging reports are more than just numbers on a page. It’s a way to better understand your cash flow, improve vendor relationships, and leverage operational performance.
While most teams understand that these reports must be run, many struggle to interpret the meaning. The report itself is simple. Using it strategically to improve cash flow, vendor relationships, operational performance, and accounts payable automation is where the real value lies.
A recent report by the Association of Certified Fraud Examiners (ACFE) found that companies lacking strong internal controls (like regular reviews of AP aging patterns) experience median fraud losses almost 2x higher than those that actively monitor their numbers.
This guide explains what an accounts payable aging report is, shows a practical example, walks through how to run it (step by step), and focuses on interpreting aging data to uncover risk, optimize payments, and improve AP efficiency.
What Is an Accounts Payable Aging Report?
Accounts Payable Aging Report — Definition
An accounts payable aging report categorizes unpaid supplier invoices by how long they’ve been outstanding; typically, 30, 60, and 90 days. It will group the data into “aging buckets” to show how past-due an invoice is, providing a quick snapshot of a company’s financial health.
What Information Is Included in an AP Aging Report
The information in an aging report is everything you need to collect past-due payments. These details include:
- Vendor name
- Invoice number
- Invoice date
- Due date
- Outstanding balance
- Aging category or bucket
- Total balances by vendor or category
Setting it up this way enables finance teams to quickly assess liabilities and then prioritize payment decisions.
Why Accounts Payable Aging Reports Matter
Accounts payable aging reports show us key insights into a company’s operational efficiency. By categorizing unpaid invoices into “aging buckets,” these reports provide clear visibility into short-term cash requirements. This allows teams to better anticipate upcoming obligations and align payment timing with cash flow, in order to maintain liquidity.
Beyond simple tracking, aging reports also enhance vendor relationship management by identifying strategic suppliers and then providing the data needed to renegotiate payment terms. It also enables smarter payment prioritization, helping companies capture more early-payment discounts. This is a huge help considering that, on average, 80% of vendors offer these discounts, but only 20% of companies take advantage of them.
Aging reports also support:
- Cash flow planning and forecasting
- Risk monitoring
- Internal financial control
An AP team that actively reviews aging patterns will better understand their payment trends.
How Accounts Payable Aging Reports Work
An accounts payable reports tool that produces an aging report helps teams gain greater visibility into:
Understanding Aging Buckets
Aging buckets divide unpaid invoices into time ranges. While 30-day intervals are common, organizations may adjust buckets depending on industry norms or internal payment policies.
The goal is to highlight urgency. The older the invoice, the greater the risk of late fees, supply disruptions, or strained vendor relationships.
The Accounts Payable Aging Formula
The accounts payable aging formula is pretty simple:
Date of Report – Invoice Date/Due Date = Aging Days
Invoices are categorized into buckets based on the number of days they are outstanding.
Current Date vs Due Date Aging Methods
There are two common approaches:
- Invoice date aging measures how long it has been since the invoice was sent.
- Due date aging measures how overdue the payment is relative to the agreed-upon terms.
Due date aging is often preferred because it reflects real payment risk and compliance with vendor terms.
Accounts Payable Aging Report Example
Sample AP Aging Report
Below is a simplified AP aging report example:
| Vendor | Total Balance | 0 to 30 Days | 31 to 60 Days | 61 to 90 Days | 90+ Days |
|---|---|---|---|---|---|
| Supply Max | $15,000 | $12,000 | $3,000 | $0 | $0 |
| Equip Central | $12,500 | $2,500 | $6,000 | $2,000 | $2,000 |
| Utility Giant | $8,250 | $7,200 | $1,000 | $50 | $0 |
How to Read an AP Aging Report
The idea is to keep everything in the 0-30 bucket whenever possible. Things are still moving around, maybe someone was on vacation, signatures are needed…30 days is a good timeframe for the majority of invoice processing to happen.
This is considered healthy. Once the buckets to the right start filling, you might have a problem. When larger amounts appear in 60+ day categories, it may be an early sign of:
- Cash flow strain
- Approval bottlenecks
- Disputes or process delays
For example, Equip Central shows an increasing risk because multiple invoices are aging beyond 60 days. What is the problem here? It needs further investigation.
Common Red Flags in AP Aging Reports
What are some early warning signs that things are headed in the wrong direction?
Keep a keen eye out for:
- Consistent large balances in 90+ days
- Heavy reliance on a small number of vendors
- Aging trends are growing worse, month over month
- Sudden spikes in overdue invoices
These signals help AP teams identify operational issues early and fix problems fast.
How to Run an Accounts Payable Aging Report
Here is the step-by-step process to manually run an AP aging report:
Step 1 – Gather Outstanding Payables
You need to compile the data first. This includes:
- Unpaid invoices
- Vendor details
- Invoice dates
- Due dates
- Balances
Step 2 – Choose Aging Method and Time Buckets
Your next move is to decide whether aging should be based on the due date or invoice data. You’ll need to define aging ranges that match your policy.
Step 3 – Organize and Calculate Aging
Group invoices into aging buckets using the aging formula (above) and calculate totals by vendor and category.
Step 4 – Review and Validate the Report
Check for:
- Missing invoices
- Incorrect dates
- Duplicate entries
- Misapplied payments
Validation ensures decisions are always based on accurate data.
How to Run an Accounts Payable Aging Report in Excel
Some AP teams choose to manage this task in Excel. Here’s how:
Creating an AP Aging Report Using Excel
