GST Invoice Generator

The split is the part worth getting right

Whether an invoice carries CGST and SGST or a single IGST depends on the place of supply. Same state as the supplier and the tax splits in half between centre and state; different states and it is one Integrated GST at the full rate. The total is identical, but the wrong choice produces an invoice your client's accountant will query, because it affects how they claim credit.

We derive it from the leading two digits of the two GSTINs, falling back to a state code you supply. Where the recipient's state is unknown we default to intra-state, because the alternative default produces an invoice the recipient cannot claim credit on.

What the document contains

Supplier and recipient blocks with GSTIN and PAN, an invoice number and date, place of supply, line items with HSN or SAC codes and per-line tax, a rate-wise summary where more than one rate appears, totals, the amount in words, and your payment details.

• Per-line taxable value and GST, with the correct split
• Rate-wise summary, which is what a client reconciles against
• Amount in words in the Indian numbering system - lakh and crore, not million
• A checklist of mandatory particulars that are still missing
• Your own details saved in this browser so the next invoice takes seconds

Nothing is uploaded, and there is no register

The PDF is generated in your browser and downloaded directly. An invoice contains your bank details, your GSTIN and your client's commercial terms, and none of it is sent anywhere - which you can confirm in your browser's network tab.

The honest consequence is that there is no invoice register. Your own details are saved in this browser if you ask for that, but there is no server-side history and therefore no guarantee that your invoice numbers are consecutive across devices or after clearing site data. Keep your own record of the last number you issued.

What it will not do

It will not decide the GST rate for your services, generate an e-invoice IRN or QR code from the GST portal, validate a GSTIN against the portal, or file anything. E-invoicing requires an integration this tool deliberately does not have.

It is a formatting tool, so the correctness of rates, HSN or SAC codes and the mandatory particulars remains yours. The checklist covers the fields that are commonly missed, not every requirement of the CGST Rules.
