Generating GST-compliant invoices
All Kasratbook invoices are GST-compliant out of the box. Here's how to customize them.
Updated March 5, 2026·4 min read
Every invoice Kasratbook generates is GST-compliant. SGST + CGST is calculated automatically based on your gym's state and the member's billing address.
Setup
- Go to Settings → Billing → GST
- Enter your GSTIN — we validate it in real time
- Set your default HSN/SAC code (we pre-fill 999723 for fitness services)
- Upload your authorized signatory's signature image (optional)
Member-side experience
Members can download their GST invoice from the member app at any time. If they need a corporate billing address, they can add it under their profile and all future invoices will use it.
