The GST invoice
A tax invoice with the right slab, the CGST/SGST split, the buyer's GSTIN when there is one, and a QR code anyone downstream can verify.
The invoice is the document that travels: to a company's accounts department, to an auditor, to a GST officer, into an expense claim. Everything on it is derived from the folio at the moment it closes, and nothing on it can be edited afterwards.
What the slab is
The GST slab on a room follows the declared tariff, by law, and the system applies the slab in force on the night — including the change that moved the thresholds. A hotel that crosses a threshold does not reconfigure anything; the rate is read and the slab follows.
Who it is made out to
- The guest, by default.
- A company, with the branch's own GSTIN and billing address, when the booking is on account.
- An OTA as payer — with the guest named on the invoice as the person who stayed.
The buyer's GSTIN can be asked for and added after the guest has gone, before the return is filed, without reissuing the bill.
Every invoice can be checked
Every invoice carries a QR code and a token. Anyone holding the paper can scan it and see that the hotel issued that document, for that amount, on that date. A phone call becomes a link.
Above the threshold
For a registered entity above the e-invoice threshold, a B2B invoice is registered with the Invoice Registration Portal through the hotel's GSP and prints the IRN and the signed QR. Cancellation within 24 hours; after that, a credit note.
