Configure GSTIN, PAN and invoice numbering

Getting your tax profile right up-front prevents a lot of paperwork later. TraWe validates GSTIN format and derives your state of supply automatically.

GSTIN and PAN

Settings → Agency → Tax. Enter your 15-character GSTIN — the state code is extracted and used for CGST/SGST vs IGST decisions on every invoice.

Numbering scheme

Pick a prefix (e.g. TRW/2026-27/) and reset frequency (financial year by default in India). TraWe assigns sequential numbers without gaps.

SAC and HSN

SAC 998552 is the default for tour operator services. You can override per line item on any invoice.
