The GST details are stored once
GST registration is a setting on your business, not a form you fill before every bill. Enter the GSTIN, legal name, registered state and address once; every invoice afterwards uses them.
- Your registered state decides whether a sale is treated as intra-state (CGST + SGST) or inter-state (IGST), based on the delivery state of that order.
- Invoice numbering runs in sequence with your own prefix, so the series stays unbroken across online orders and counter sales.
- A business that is not GST-registered produces invoices without a GSTIN and without a tax split — the bill is still the same bill.
- Composition-scheme businesses are supported: invoices are raised without collecting tax.
