Ageing

Definition

Ageing sorts unpaid bills by how many days old or overdue they are, so you can see which dues are fresh and which are getting hard to collect.

Ageing is the sorting of unpaid bills by how old they are, usually into buckets such as 0–30, 31–60, 61–90 and over 90 days, to show which dues are getting stale.

Example

Gupta Electricals owes ₹1,50,000: ₹90,000 billed 12 days ago and ₹60,000 billed 95 days ago. The total looks fine, but the ageing report puts ₹60,000 in the over-90-days bucket, so that bill gets a call and a statement before any new credit is given.

Common misunderstandings

  • Watch outReading only the total due and ignoring how much of it sits in the 90+ days bucket.
  • Watch outLeaving receipts on account, so old bills keep showing as unpaid in the ageing report.

Why ageing matters

Two customers can owe the same amount and be very different risks. One owes ₹1,00,000 from last week's bill; another owes ₹1,00,000 from bills five months old. Ageing makes that visible. The older a bill gets, the harder it usually is to collect, so ageing tells you where to spend collection effort, which customers to stop supplying on credit, and which balances may need a provision.

Example

Customer0–30 days31–6061–9090+Total
Arora Traders₹80,000₹20,000₹0₹0₹1,00,000
Bansal Agencies₹10,000₹15,000₹30,000₹45,000₹1,00,000
Total₹90,000₹35,000₹30,000₹45,000₹2,00,000

Both owe ₹1,00,000, but ₹75,000 of Bansal's dues are over 60 days. That account needs a call and a statement this week, and perhaps a hold on new credit. Our guide to ageing analysis explains how to act on each bucket.

Ageing by bill date or due date

Ageing can count from the bill date or from the due date (bill date plus credit days). Counting from the due date shows what is truly overdue; counting from the bill date shows how long money has been out. Pick one and use it consistently, and tell your team which one the report uses. Customers often argue about overdue days, so a statement that shows both bill date and due date avoids most disputes.

Where it shows up in TallyPrime

TallyPrime has ageing analysis on its bills receivable and payable reports, with ageing periods you can set. It needs bill-wise details on party ledgers; payments not linked to bills distort it. Cashflow OS shows ageing on receivables and payables from the synced Tally data, on phone and web. See bill-wise details.

Questions about Ageing

What ageing buckets should I use?
Match them to your credit terms. With 30-day terms, 0–30, 31–60, 61–90 and over 90 days work well.
Is ageing used for payables too?
Yes. Payables ageing shows which supplier bills are getting old, which helps plan payments and keep supplier trust.
Why does my ageing show old bills that were paid?
Usually because payments were entered on account instead of against bills. Adjust them against the right bills.
Should I age bills from the bill date or the due date?
Either works if you use it consistently. Due-date ageing shows what is truly overdue; bill-date ageing shows how long money has been out.
What should I do about bills over 90 days old?
Call the party, send a bill-wise statement, and consider holding new credit until the old bills are settled. Ask your CA whether any of it needs a provision.
