Quick answer: GST billing for Restaurant in India requires correct tax invoices (or bills of supply where applicable), HSN/SAC on lines, proper CGST/SGST vs IGST split, linked credit/debit notes, and exportable sales registers for GSTR-1. Restaurant services attract 5% GST without ITC on food service (structure varies ? confirm with CA). Packaged beverages sold may carry different rate. Service charge policy must be clear on bill. Invoice series discipline daily, not month-end panic.
Arjun?s family restaurant in Mumbai had six tables turn at once on a rainy Saturday ? and two KOTs swapped between Table 4 and Table 7. After structured kitchen tickets and a single captain rule, the kitchen stopped cooking strangers? paneer tikka and his mother finally trusted the day-end sales screen.
The GST officer did not care that Arjun's family restaurant in Mumbai was busy. The clinic rejected the bill because HSN was missing. That afternoon, Arjun learned what CA firms mean by "compliance is not optional ? it is collection insurance."
This guide explains GST billing for Restaurant owners in plain language ? not CA jargon. Use it to train staff, audit your current invoices, and choose software that prevents repeat mistakes.
Why GST billing for Restaurant is different from a generic shop
Restaurants fail softly before they fail loudly: wrong KOT, merged tables nobody admits, delayed add-ons, complimentary confusion, and split-bill fights at the door. Throughput plus accuracy beats pretty UI alone.
Your typical sale involves table service, split bills, and kitchen order coordination. Each path has different invoice fields, tax treatment, and record-keeping expectations.
GST invoice basics every Restaurant owner should know
- Tax Invoice: For taxable supplies ? shows GSTIN of supplier, buyer GSTIN (if B2B), HSN/SAC, taxable value, tax rate, CGST/SGST or IGST.
- Bill of Supply: For exempt or composition cases ? format differs; know which applies to you.
- Credit Note: When you reduce value after original invoice ? must link to original.
- Debit Note: When you increase taxable value ? less common at retail counter but matters in B2B.
HSN and SAC for Restaurant: practical examples
Example mapping: SAC 996331 ? restaurant service (dine-in, taxable at applicable food service rate) ? 5% GST on restaurant services (non-ITC regime); packaged drinks may be 12?18% separately.
Map HSN at product master level. Counter staff should never type HSN during rush hour. One wrong code repeated 200 times a month becomes an audit theme.
B2B vs B2C billing at Restaurant
B2C (walk-in): Customer may not have GSTIN. Still issue proper tax invoice with your GSTIN, HSN, and tax breakup. Many Restaurant owners underestimate how often walk-ins are actually small businesses buying without declaring GSTIN.
B2B (registered buyers): Capture GSTIN, verify on bill, ensure interstate vs intrastate tax split is correct. Clinic, contractor, dealer, and school PO accounts fall here.
CGST/SGST vs IGST ? the mistake that hurts at month-end
Intrastate sales: CGST + SGST. Interstate sales: IGST. Software should apply based on party state and your registration state ? not staff guesswork.
Restaurant owners selling to buyers in other states (common in wholesale-leaning family restaurant operations) need interstate discipline from day one.
Credit notes, returns, and exchanges
Ingredient consumption linkage for recurring menu items reveals food cost drift. Kitchen wastage and complimentary meals should reduce stock or be logged explicitly. Delivery packaging charges need separate tracking from dine-in.
Return without linked credit note = GST mismatch + stock ghost. Train staff: every return starts with original bill lookup.
GSTR-1 workflow for Restaurant (owner + CA view)
- Daily: ensure every sale is in software ? no manual side register
- Weekly: owner reviews tax summary by rate
- Monthly: export sales register; share with CA before due dates
- Reconcile: software totals vs GSTR-1 filed ? investigate gaps immediately
E-invoicing and e-way bill ? when Restaurant must care
Thresholds change ? confirm with your CA annually. If applicable, your billing software must support IRN generation and QR on invoice. Even if below threshold today, pick software with e-invoice readiness so growth does not force a painful migration.

Document trail your CA actually wants from Restaurant
Monthly packet: sales register (invoice-wise), purchase register, credit/debit notes, stock summary, and bank/UPI collection reconciliation. If your counter cannot produce sales register in software format, CA re-enters data ? you pay twice.
For family restaurant operations selling thali combos and KOT items, map every product to HSN once. Rush-hour billing should never involve Googling tax rates.
Composition scheme vs regular GST ? quick orientation
Some micro Restaurant businesses opt for composition (rules and limits apply ? confirm with CA). Composition cannot collect GST from customers on invoice the same way; invoice format differs. If you are regular taxable supplier, tax invoice discipline in this guide applies fully.
Inter-state sales and IGST for Restaurant
Selling to buyers in other states (dealers, clinics, contractors, schools) triggers IGST when place of supply rules say so. Software must use party state + your registration state ? not cashier memory. One wrong IGST/CGST mix repeated across 50 B2B bills creates reconciliation pain.
Self-audit checklist before CA visit or GST notice

- 5 credit notes: linked to originals?
- Stock of 20 fast movers: system vs shelf spot count
- Party ledger: top 5 dues match customer acknowledgement
- Purchase register: last month fully entered?
Restaurant services attract 5% GST without ITC on food service (structure varies ? confirm with CA). Packaged beverages sold may carry different rate. Service charge policy must be clear on bill. Invoice series discipline daily, not month-end panic.
