Frequently Asked Questions

Is HSN/SAC code mandatory on invoices?

Yes — 4-digit codes for turnover up to ₹5 Crore, 6-digit codes for turnover above ₹5 Crore.

What's the difference between CGST+SGST and IGST?

CGST + SGST applies when supplier and customer are in the same state (intra-state). IGST applies when they're in different states (inter-state). Our tool auto-detects this based on the states you select.
