The Complete Guide to 100% GST-Compliant Retail Billing & GSTR-1 Filing

Tax & Business Compliance Team • September 20, 2026 • 7 min read

GST compliance does not have to be a stressful month-end nightmare. With the right cloud POS software, every transaction automatically categorizes tax components in the background.

Automated CGST, SGST, and IGST Calculation

Whether you sell locally in-state or dispatch items inter-state, the software automatically splits tax amounts into central and state components. Products with mixed tax rates (e.g., 5% food items alongside 18% cosmetics) are calculated accurately down to the paisa.

HSN and SAC Code Management

Mandatory HSN code regulations require proper code mapping on invoices. Groccy POS allows you to assign HSN codes during product entry or bulk upload, which are then printed neatly on tax invoices.

One-Click GSTR-1 and GSTR-3B Excel/JSON Export

Instead of manually compiling paper ledgers for your accountant, you can download complete B2B, B2C Large, B2C Small, and HSN-wise summaries formatted specifically for the GST portal in seconds.
