Food cost is where cafe profits quietly disappear. You can be busy, well-reviewed, and full every evening, and still barely break even because too much of what you buy ends up in the bin, walks out the back door, or gets served without ever being charged. The good news is that food cost is one of the most controllable numbers in your business — not through one big change, but through a handful of steady habits.

Know your food cost percentage

Food cost percentage is simply the cost of ingredients divided by the sales they generate, as a percentage. If a coffee costs you Rs 40 in beans, milk, and cup and you sell it for Rs 160, that item runs at 25%. Cafes and restaurants generally aim to keep overall food cost within a target range — where exactly depends on your concept and pricing.

You cannot manage what you do not measure. Before optimising anything, work out your current food cost for a full month: opening stock value, plus purchases, minus closing stock, gives you what you actually consumed. Compare that to sales. The gap between what you should have used (based on what you sold) and what you actually used is your waste, theft, and error — and that gap is where the money is.

Track stock like it is cash

Inventory is cash sitting on your shelves. Treat it that way.

Do a physical count on a fixed schedule. Weekly for most items, more often for high-value or fast-moving ones like meat, cheese, and coffee. Pick a time — usually close or open — and stick to it.
Count in consistent units. Decide whether milk is in litres or packets and never mix. Inconsistent units are the single biggest cause of counts that never reconcile.
Value your stock. A count of “12 bags of coffee” means little; “12 bags at Rs 1,200 = Rs 14,400” tells you what is tied up on the shelf.

A POS like GoServe can deduct ingredients from stock as items sell and flag when a count drifts from what sales predict, which turns the weekly count from a guessing game into a quick check against a known expected figure.

Set par levels

A par level is the minimum quantity of an item you want on hand before you reorder. Setting pars stops both problems at once: running out of your best-seller mid-service, and over-ordering perishables that spoil before you use them.

Set pars based on how fast something moves and how long delivery takes. Coffee beans with a reliable weekly supplier need a different par than fresh milk you buy daily. Review pars before festival season — your Dashain and Tihar demand will not match a quiet monsoon week.

Spot waste and theft

Waste and theft look identical on a spreadsheet: stock that left without a matching sale. You separate them by watching where it happens.

Waste usually shows up as:

Perishables spoiling before use — a sign your pars are too high or your rotation is poor.
Over-portioning — a barista free-pouring milk, a cook heaping plates beyond spec.
Prep mistakes and burnt batches that never get logged.

Theft or leakage shows up as:

Stock disappearing with no waste log and no sale — cash sales not rung up, drinks given to friends off the books, product walking out the back.
A stubborn gap between expected and actual usage that does not track with any waste you can see.

The defence against both is the same: log everything. Log wastage when you throw something out. Log staff meals and comps. Log the coffee you pulled to re-dial the grinder. Once every legitimate reason a unit can leave is written down, whatever remains in the gap is the problem you need to chase.

If stock can leave your cafe without leaving a record, you do not have an inventory problem — you have a recording problem, and it will always look like theft even when it is only mess.

Cost your recipes

You cannot price well or spot a problem item without knowing what each dish costs to make. Recipe costing means breaking a menu item down to its ingredients and their cost.

Take your best-selling latte: espresso (beans), milk, cup, lid, and a share of syrup if flavoured. Add it up and you have the true cost. Do this for every item and two things become obvious — which items make you real money and which are barely worth making. When a supplier raises the price of milk, recipe costing tells you instantly which menu prices need to move and by how much, instead of guessing.

Recipe costing also disciplines portions. Once the kitchen knows a dish is built to a spec that costs Rs X, over-portioning becomes visible rather than invisible.

Use low-stock alerts

The old way is to notice you are out when a customer orders it. The better way is a low-stock alert that fires when an item drops to its par level, so you reorder before you run dry. This matters most for items that anchor your menu — running out of coffee in a coffee shop is not a small mistake. Software that tracks stock against sales can flag low items automatically; if you are on pen and paper, a simple reorder board by the store cupboard works too, as long as someone owns it.

Keep your suppliers disciplined

A surprising amount of food cost leaks in at the receiving door.

Check every delivery against the order and the bill. Weigh what should be weighed. Suppliers make mistakes — some honest, some not — and if you sign without checking, you pay for what you did not get.
Keep supplier bills. They are your purchase record for both cost tracking and VAT input claims. See our note on VAT and compliant billing for why purchase records matter at tax time.
Track price changes. When a supplier’s price moves, it should trigger a look at your recipe cost and menu price, not just quiet acceptance.
Do not over-rely on one supplier for critical items. A single delivery falling through the week before Tihar is the kind of thing that ruins a rush.

Small habits, protected margin

None of this is complicated. Count on a schedule, value your stock, set pars, log every reason product leaves, cost your recipes, react to low-stock alerts, and check what your suppliers deliver. Each habit is minor on its own; together they close the gap between what you buy and what you sell — and that gap is your profit.

Food cost control is not a one-time project. It is a rhythm you build into the week, the same way you build the opening and closing routines that keep the rest of the cafe running.
