GST billing guide for retail shops in India
28 May 2026 · 6 min read
A practical walkthrough of CGST, SGST, IGST, HSN codes, and what small shop owners should get right on every invoice.
If you run a retail shop in India, GST compliance is not optional once you cross the registration threshold. The good news: most daily billing mistakes come from a few repeatable gaps — wrong tax type, missing HSN, or inconsistent party details.
For local sales within your state, CGST and SGST apply. For interstate sales, IGST applies. Your billing software should pick this up from party and business state automatically so you don't calculate manually on every bill.
HSN codes matter for product classification and returns. Even if your shop sells hundreds of SKUs, start with correct HSN on your top-selling items and expand over time.
