Leave the original invoice alone. Raise a credit note that points back to it, give the return a reason code, and post the stock movement in the same step. The credit note series supplies the next number, so the whole month can be rebuilt without anyone guessing which document came first.
Why the invoice must stay untouched
Once an invoice is issued, the PDF sits in the buyer’s inbox and, above the e-invoicing limit, the IRN sits on the portal. Editing breaks the match. Your copy and theirs now differ.
A return is a new event. It falls on a new date, often in a later month, and the auditor will expect a separate document with its own number and its own tax line.
That document is the credit note.
Steps one and two: find the invoice, record the reason
Search for the invoice by number, party name or e-way bill, and the credit note copies its lines, leaving the clerk to tick only the SKUs that came back. Quantities come from the return slip.
Pick a reason code. Damaged in transit, wrong size, short expiry, courier refusal, buyer cancellation and rate difference cover most returns for a distributor or an online brand, so keep the list short.
Never accept free text alone. A code lets you count returns by cause every month and spot the supplier, courier or packing table behind the worst ones.
- Original invoice number and date pulled in
- Items and quantities, never above billed
- Reason code and a short note
- Photo or return slip attached
- Name of the approver
Steps three and four: post stock with the credit note
Stock goes in with the credit note. Post one and leave the other for later, and within a week the bin count and the sales ledger drift apart, so no one knows which figure to trust.
Send returned items to a hold location first, such as a quarantine bin or a damaged-goods shelf, and let the stores in-charge inspect each carton before it moves anywhere. Fit stock goes back to saleable. Broken stock is written off.
Tax follows the original supply. The system copies HSN, rate and the CGST, SGST or IGST split from the invoice, so the clerk never picks them again and a return cannot change the rate.
Step five: numbering and the month’s record
Credit notes take their own series. Each number is used once. A cancelled draft keeps its number, marked void, so the register shows no gap that you cannot explain to an officer who asks.
The raising date decides the month. Write the month rule down before the quarter closes, because two clerks will place a credit note in different months, one by invoice date and one by return date.
At month-end, list each credit note with its invoice, value and reason, and your accountant can rebuild the month without opening a single PDF.
- Separate series for credit notes
- Void numbers listed, never deleted
- Return date decides the month
- Link to the invoice always visible
Check the flow with three real returns
Pick three returns from last month. Take a full return, a part return and a rate difference, raise them on a test copy, and compare bin stock, tax split and ledger balance with what happened.
A manual fix in any of the three puts that case on the checklist before go live, and the test repeats after any change to series or tax setup. Keep the results sheet beside the checklist.
Goods return and credit note checklist
Five blocks, one for each step, make up this single-sheet checklist: find the invoice, record the reason, post the stock, take the next number, file in the month. Each block carries tick boxes for the fields that must be filled, a signature line for the approver and a line for the credit note number. A small table at the foot lists the reason codes: damaged in transit, wrong size, short expiry, courier refusal, buyer cancellation and rate difference, each with a one-line meaning.

Can I cancel an invoice instead of raising a credit note?
Only within the window and conditions your CA confirms, and never after the buyer has claimed credit on it, which is why returns normally take a credit note.
Does a credit note need an IRN?
Where your invoices fall under e-invoicing, the credit note usually needs an IRN, so confirm the current rule with your CA and let the billing system generate it.
What if only part of the order is returned?
Raise the credit note only for the lines and quantities that came back, and let the system refuse any quantity above what the invoice billed for that line.
Where should returned stock go?
To a hold location first. After inspection, the stores in-charge moves it to saleable stock, sends it for repair or writes it off against the reason code, and the credit note stays unchanged.
