Implementation Guide

1

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.

💡Create a GST slab mapping for your entire product catalog — errors compound across thousands of invoices
💡SpireStock auto-assigns GST slabs based on HSN codes configured in the product master
⚠️Applying wrong GST slab on invoices creates input credit mismatch — the brand's accountant and your retailer's accountant will both flag it
2

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.

💡Download the GST HSN code lookup from cbic.gov.in for your product categories
💡Configure HSN codes in SpireStock's product master once — they auto-populate on every invoice
⚠️Incorrect HSN codes can delay or deny input tax credit claims for your retailers — accuracy matters
3

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.

💡Invoice numbering must be sequential within a financial year — no gaps allowed
💡For unregistered retailers (below ₹40L turnover), you still issue a tax invoice but buyer GSTIN is 'URP' (Unregistered Person)
⚠️Missing mandatory fields on invoices can result in ₹10,000 penalty per invoice under GST rules
4

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.

💡SpireStock auto-generates credit notes linked to original invoices, ensuring correct GST adjustment
💡Track returns at batch level for FMCG — this helps with brand claims and FIFO management simultaneously
⚠️Unlinked credit notes (without original invoice reference) are invalid under GST — ensure every credit note traces to a specific invoice
5

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.

💡Reconcile your purchase register with GSTR-2A monthly — mismatches mean unclaimed ITC
💡SpireStock auto-reconciles purchase and sales data for seamless ITC tracking
⚠️ITC on goods used for personal purposes, exempt supplies, or goods written off as losses is not claimable — segregate correctly
6

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.

💡Set calendar reminders for 8th and 18th of every month as return preparation deadlines
💡SpireStock exports sales data in GSTR-1 compatible format — upload directly to GST portal
⚠️Continuous default in return filing (6+ months) can lead to GST registration cancellation — set this as a non-negotiable deadline
