Restaurant accounting is not about becoming an accountant — it is about knowing a handful of numbers well enough to catch problems before they eat your margin. In an industry where food spoils, staff turnover is high, and GST applies to almost every sale, small leaks add up fast. This guide covers the accounting basics every Indian restaurant owner should understand to stay profitable and compliant.
Know your prime cost
The two biggest costs in any restaurant are food (cost of goods sold) and labour. Together they form your prime cost, and it is the single most important figure in restaurant accounting. If food and labour combined swallow too much of your revenue, no amount of extra footfall will make you profitable. Track prime cost as a percentage of sales every week, not just at year-end, so you can react while it still matters.
- Food cost %: cost of ingredients used, divided by food sales.
- Labour cost %: total wages and staff costs, divided by sales.
- Prime cost %: the two added together — your core efficiency number.
Control food cost with recipe-level tracking
Menu-price guesswork is where margins quietly die. When you know the exact ingredient cost of each dish and track it against what you actually sell, theoretical food cost can be compared to real consumption. The gap between the two reveals waste, over-portioning, or pilferage. Recipe-level POS and inventory tracking turns this from a monthly guess into a live number you can trust.
Keep GST-ready records from day one
In India, accounting and GST compliance are inseparable. Every sale should be billed with the correct rate and CGST/SGST split, and every purchase invoice should be filed so your records reconcile with your returns. Standalone restaurants on the 5% rate generally cannot claim input tax credit, so purchase GST becomes part of your cost — which makes accurate food costing even more important. Clean books make GST billing and monthly filing straightforward instead of stressful.
Run a daily sales report
Cash-heavy businesses need daily discipline. A daily sales report — sometimes called a Z-report — should reconcile total sales, payment modes (cash, card, UPI), delivery-app collections, discounts, and GST collected. Doing this every night catches till shortages, missed bills, and reconciliation gaps before they compound. It also gives you the raw data your accountant needs for monthly and GST filings.
Separate cash flow from profit
Many owners confuse a full cash drawer with profit. Cash flow is money moving in and out; profit is what remains after every cost — including rent, GST liability, and supplier dues — is accounted for. A restaurant can be cash-rich one week and still be unprofitable if fixed costs and liabilities are not set aside. Track both separately.
Watch inventory and wastage
Perishable stock is a real cash risk. Regular stock counts, first-in-first-out usage, and variance reports between expected and actual inventory expose spoilage and shrinkage. Even a couple of percentage points of unexplained wastage, tracked over a year, can equal a month’s profit. Tie inventory movements to your sales so every item consumed maps back to a bill.
The numbers to review each week
- Prime cost % — is food + labour under control?
- Food cost variance — theoretical vs actual consumption.
- Daily sales reconciliation — do payments tie to bills?
- GST collected vs payable — set the liability aside, don’t spend it.
- Cash position vs dues — profit is not the same as cash.
You do not need to master accounting theory to run a healthy restaurant — you need reliable numbers, reviewed often. Connecting billing, inventory, and reporting through one finance-ready system gives you those numbers without manual spreadsheets. For anything involving tax positions, statutory filings, or how to structure your books, work with a qualified CA.
Frequently asked questions
What is the most important number in restaurant accounting?
Prime cost — your food cost plus labour cost as a percentage of sales. It is the clearest indicator of operating efficiency, and reviewing it weekly lets you correct problems before they erode your margin.
How do I calculate food cost percentage?
Divide the cost of ingredients used in a period by the food sales for that period, then multiply by 100. Comparing this theoretical figure to actual stock consumption highlights waste or pilferage.
Do I need an accountant if I use restaurant software?
Software keeps your daily records, billing, and inventory accurate and GST-ready, which makes an accountant’s job easier. For statutory filings, tax structuring, and compliance advice, you should still work with a qualified CA.
How does GST affect restaurant accounting?
Every sale must carry the correct GST rate and CGST/SGST split, and the GST you collect is a liability to set aside, not income. Since most standalone restaurants cannot claim input tax credit, purchase GST adds to cost, making accurate food costing essential.
