Frequently asked questions
When is it CGST + SGST vs IGST?
If the supplier and the place of supply are in the same state, GST splits into CGST and SGST (half each). If they are in different states, a single IGST is charged instead. Use the intra/inter-state toggle to switch.
What is an HSN / SAC code?
HSN (Harmonised System of Nomenclature) codes classify goods and SAC codes classify services for GST. Add the relevant code per line item; the requirement to show it depends on your turnover.
Is this GST invoice generator free?
Yes. You can create and download up to 3 GST invoices per day for free. Free invoices include a small SnapBilly watermark; Pro removes it and unlocks unlimited GST invoicing.
Is this a substitute for professional tax advice?
No. It produces a GST-style tax invoice to help you bill correctly, but GST rules (rates, reverse charge, e-invoicing thresholds) vary. Confirm requirements with your accountant.
