Food cost is usually the largest controllable expense in a restaurant, and most owners only learn their real number once a month – if at all – when the accountant totals the purchase bills. Inventory management is how you see it daily. This guide describes a system that busy restaurants can actually sustain, and the software features that make it possible.
Why food cost drifts without you noticing
Small leaks add up: an extra 20 g of chicken per biryani, a cook who rounds up, a supplier whose 10 kg bag weighs 9.4 kg, a fridge that fails overnight, staff meals that never get logged, and parcel orders that go out without a bill. None of these show up on a sales report. They show up only when you compare what you should have used (from recipes and sales) with what you actually used (from stock counts).
That comparison – theoretical vs actual usage – is the whole point of inventory management.
Step 1: Decide what to track
You do not need to track every spice. Start with the 20% of ingredients that make up 80% of cost: meat, fish, rice, oil, dairy, packaged beverages, and anything that walks out the door easily. Add the rest later if you want.
Step 2: Write recipes for your top sellers
A recipe in the POS is a list of ingredients and quantities per portion. When a biryani sells, 180 g rice, 150 g chicken, 20 ml oil and so on are deducted automatically. Be honest about quantities – measure three portions during a normal service and average them. Recipes also give you the cost per plate, which makes menu pricing a calculation instead of a guess.
Step 3: Set par levels and reorder points
For each tracked item set a par level (what you want on hand before a busy day) and a reorder point (when to buy). The POS then shows a purchase suggestion list every morning instead of the cook discovering at 7 pm that the chicken is over.
Step 4: Record purchases the same day
Every supplier delivery goes into the system with quantity and price. This is the step that fails most often because it is boring. Make it someone's job, keep it to two minutes per bill, and tie it to paying the supplier – no entry, no payment.
Step 5: Log waste and staff meals
A waste log is not about blame. It is the only way to separate spoilage from theft in the variance report. Log spoiled stock, dropped plates, remakes and staff meals with a reason.
Step 6: Count stock on a rhythm
Count high-value items daily at close (meat, fish, packaged drinks), everything else weekly. A ten-minute count of the top twenty items gives you most of the value.
The three reports that matter
- Variance report – theoretical usage (from sales × recipes) vs actual usage (opening + purchases − closing). A gap of more than 3–5% on a high-value item is a signal to investigate.
- Food cost % – cost of goods sold ÷ food sales, by day and by category. Watch the trend, not the single number.
- Item profitability – margin per dish after recipe cost. This is where you find the popular item that barely makes money and the high-margin one that deserves a better spot on the menu.
What to look for in inventory software
- Recipe-based automatic deduction per sale, including modifiers and add-ons
- Unit conversions (buy in kg, use in g; buy in cases, sell in bottles)
- Purchase entry with supplier and price history, so you see price creep
- Low-stock alerts and purchase suggestions
- Waste logging with reasons
- Stock count screens that work on a phone in the storeroom
- Variance and food-cost reports for any date range, per branch
MealNix includes recipe management, automatic stock deduction, purchase and supplier records, low-stock alerts, waste tracking and inventory reports, with advanced unit conversions and purchase suggestions on paid plans.
FAQ
What is a good food cost percentage for a restaurant in India?
Most full-service restaurants aim for 28–35% food cost; QSRs and cafés often run lower, and seafood or fine dining higher. The useful number is your own trend week to week, and the gap between theoretical and actual usage.
How often should a restaurant count inventory?
Count high-value, easily pilfered items daily at closing and everything else weekly. Short, consistent counts of the top twenty items beat a full monthly count that never happens.
Do I need barcode scanners for restaurant inventory?
No. Restaurants mostly track raw ingredients by weight or volume, which are entered manually. Barcodes help for packaged goods such as bottled drinks and retail items.
Can a small restaurant manage inventory without dedicated staff?
Yes, if the POS deducts stock automatically from sales and the owner limits tracking to the top cost items. The only manual steps are entering purchases and a short daily count.
