Step-by-Step
Implementation Guide
Understand GST Structure for Distribution
Distributors deal with two types of GST: CGST + SGST (intra-state sales, same state) and IGST (inter-state sales). FMCG products span multiple tax slabs: 0% (unpackaged staples), 5% (packaged food items under ₹1000/kg), 12% (processed foods, butter), 18% (most FMCG, personal care), and 28% (luxury items, aerated beverages). Your billing must apply the correct rate per product.
Configure Correct HSN Codes
Every product on your invoice must carry a valid HSN (Harmonized System of Nomenclature) code. For FMCG distributors, common HSN codes: 0401 (milk), 0403 (curd/yogurt), 0405 (butter/ghee), 1704 (confectionery), 2201-2202 (water/beverages), 3401 (soap), 3304 (cosmetics). Distributors with turnover above ₹5 crore must use 6-digit HSN codes.
Master Invoice Format
GST tax invoices must include: your GSTIN, buyer's GSTIN (if registered), invoice number (sequential), date, HSN code per item, taxable value, CGST/SGST or IGST rate and amount, total value, place of supply, and digital or ink signature. SpireStock generates fully compliant invoices automatically.
Handle Credit Notes & Returns
When retailers return goods, issue a credit note (not a new invoice). Credit notes must reference the original invoice number and date. Credit notes reduce your GST liability in the return period they're issued. Time limit: credit notes for a financial year must be issued before September 30 of the following year.
Maximize Input Tax Credit (ITC)
ITC is your biggest GST benefit — the GST you pay on purchases from brands can offset the GST you collect on sales to retailers. To claim ITC: ensure your purchase invoices are GST-compliant, verify supplier GSTIN, match invoices with GSTR-2A auto-populated data, and file returns on time. Unclaimed ITC is money left on the table.
File Returns on Time
Distributors must file: GSTR-1 (outward supplies, by 11th of next month), GSTR-3B (summary return with tax payment, by 20th of next month). QRMP scheme available for turnover under ₹5 crore (quarterly GSTR-1, monthly GSTR-3B). Late filing attracts ₹50/day (₹20/day for nil returns) up to ₹10,000.
