What your purchase invoice must show for the input credit to hold
A checklist you can run against any supplier's invoice in ten seconds. Miss one of these and the credit is the one at risk, not theirs.

If you are GST-registered, the invoice your supplier hands you is the document your input credit rests on. It is worth ten seconds of checking before it goes in the file.
This is a practical checklist, not tax advice — your accountant has the final word on your own position.
Run through these
- Your GSTIN, printed correctly. The single most common problem. A credit claimed against a mistyped GSTIN will not match in your GSTR-2B.
- The supplier's GSTIN and legal name. Both should be verifiable on the GST portal.
- A serial invoice number and date. Numbers must run in an unbroken series for the financial year.
- HSN code per line. Not per invoice — per product line.
- Taxable value, tax rate and tax amount, shown separately. A single "total incl. GST" figure is not enough.
- Place of supply. This is the one that decides which tax applies.
Why place of supply decides the tax type
If the supplier and you are in the same state, the tax splits into CGST + SGST. If you are in different states, it is a single IGST line. Same total either way — but the wrong one on the document is a mismatch when it is filed.
We are in Chennai, so a Tamil Nadu buyer gets CGST + SGST and a buyer outside the state gets IGST. Our system decides this from the GSTIN on the order, not by hand, so it cannot be set wrong by accident.
Give your GSTIN at order time, not after
An invoice is issued against the details held when it is raised. Adding a GSTIN afterwards means the original has to be credited and a fresh one issued — avoidable paperwork for both sides.
When you place an order there is a GSTIN field. Filling it in means your invoice carries it from the start. It is optional — you can buy without one — but if you are registered, use it.
Where to find yours
Every invoice we issue is against GSTIN 33AQQPM7968R1ZJ, which you can check on the GST portal before you order from us or anyone else. Ask for a copy of any invoice at any time and we will send it.
If you want a trade account with volume rates, send your GSTIN through become a partner and we will open one.
