# Overdue Ageing

**Overdue ageing groups unpaid invoices by how many days past due they are, usually 0–30, 31–60, 61–90 and over 90 days.**

## What it means

An overdue ageing report sorts what buyers owe you into buckets based on how late each invoice is:

- **0–30 days overdue:** recently due, usually a gentle reminder is enough.
- **31–60 days:** needs a call and a dated [promise to pay](/en/glossary/promise-to-pay).
- **61–90 days:** escalate; consider a formal [demand letter](/en/glossary/demand-letter).
- **90+ days:** the hardest money to recover; decide on next steps quickly.

Some businesses age invoices from the invoice date instead of the due date. Either works if you are consistent, but ageing from the due date shows true lateness.

## Why it matters for getting paid

The older an invoice gets, the less likely it is to be paid in full. An ageing report tells you where to spend your limited time each week. It also shows which buyers are slipping before they become a real problem.

**Example:** Your total outstanding is ₹20,00,000. The ageing shows ₹14,00,000 at 0–30 days, ₹3,50,000 at 31–60, ₹1,50,000 at 61–90 and ₹1,00,000 over 90. That last ₹1,00,000 deserves a focused plan this week.
