Accounts Receivable Aging Report Explained for Business Owners

An accounts receivable aging report is one of the most important financial documents for any B2B business—and one of the first things a factoring company will request when evaluating your application. Understanding how to read it, and how to keep it healthy, directly affects your cash flow and your ability to access financing.

What Is an Accounts Receivable Aging Report?

An A/R aging report is a summary of all outstanding invoices, organized by how long they've been unpaid. It typically shows invoices grouped into buckets: current (not yet due), 1–30 days past due, 31–60 days past due, 61–90 days past due, and 90+ days past due.

The report gives you an instant snapshot of your collections health: how much you're owed, who owes it, and how long they've owed it.

How to Read an A/R Aging Report

A healthy A/R aging report has most balances in the "current" or "1–30 days past due" columns, with minimal amounts in the 60+ day buckets. Warning signs include:

• A high percentage of receivables 60+ days past due (suggests chronic slow payers or collection problems)
• A single customer dominating the aging (high concentration risk)
• Invoices older than 90 days that haven't been written off (suggests disputed or uncollectible invoices)

Why Factoring Companies Care About Your Aging Report

When a factoring company reviews your application, they scrutinize your aging report carefully. They're looking for:

Invoice eligibility: Most factors will only advance against invoices that are current or no more than 30–60 days old. Invoices more than 90 days past due are typically ineligible.

Concentration risk: If one customer represents 50%+ of your receivables, some factors will limit how much of that concentration they'll fund, or charge higher rates.

Customer payment behavior: If a customer has a history of paying 45+ days past your stated terms, the factor may exclude them or offer a lower advance rate on their invoices.

Improving Your A/R Aging Before Applying for Factoring

If your aging report has problematic invoices, take these steps before applying:

1. Write off truly uncollectible invoices so they don't distort your report
2. Follow up aggressively on slow-paying accounts to move invoices from the 60+ day bucket
3. Document disputed invoices separately with explanations—factors can often work around known disputes
4. Consider customer credit policies that reduce the likelihood of future slow-payment situations
