GST Invoice Generator
Self-ship (merchant-fulfilled) sellers must issue their own GST invoices. Drop your unshipped orders report (Seller Central → Orders → Order Reports → Unshipped Orders) and get one merged A4 PDF — a TAX INVOICE page per order, with CGST+SGST or IGST worked out from the buyer's state.
How to use this tool & where to get the input
Input — from your Amazon seller account
Orders → Order Reports → Unshipped Orders → Request report → Download (a .txt file). Enable the address columns in the report settings on that page so buyer ship-to details appear on the invoices.
Steps- Fill in your seller details once — business name, address, GSTIN, state and invoice numbering (saved in your browser).
- Drop the unshipped-orders report file.
- Pick the GST rate, whether prices include GST, and set unit prices per SKU (auto-filled if the report has a price column). HSN codes are optional.
- Generate — one merged A4 PDF, one invoice per order, with CGST+SGST for same-state buyers and IGST otherwise. Verify with your CA before filing.
Your seller details (saved in this browser)
The first 2 digits of your GSTIN are your state code — it is auto-filled from the GSTIN if you leave it blank. Invoice numbers run prefix + number, incrementing per order (leading zeros in the starting number are kept).
🔒 Private by design — the report (including customer names and addresses) and your GSTIN are processed entirely in your browser and never uploaded anywhere.
Your business name, address and GSTIN above are remembered in this browser so you don't retype them. On a shared or public computer, clear them when you're done.
