How to take restaurant inventory without losing your Sunday
Inventory is where food cost stops being a theory: the count is what turns 'we should be at 30%' into what you actually used. Here's the method — count by section, fix the cadence, compute usage and variance, and turn the numbers into pars and orders — without the double-entry that makes teams give up on it.

Definition
Taking inventory means counting what the venue holds — food, beverage, packaging — at a fixed moment, valued at purchase prices. It's what turns theoretical food cost into actual: usage is opening stock plus purchases minus closing stock, and usage over sales is your real cost of goods.
Usage = opening stock + purchases − closing stock · Actual food cost % = usage ÷ sales × 100
Taking inventory, step by step
The count itself is simple. What makes it fast and repeatable is the setup around it — four steps.
- 1
Organize by section, shelf-to-sheet
Count in the order the venue is laid out — walk-in, dry store, bar back, freezer — with the sheet in the same order as the shelves. A count that jumps around the storeroom takes twice as long and misses twice as much.
- 2
Fix the cadence — and keep it
A full count weekly at minimum; high-value and highly perishable items more often. Always the same day and moment (before opening, after closing), or week-to-week comparisons mean nothing. Consistency beats frequency.
- 3
Compute usage — and value it at current prices
Opening stock plus the week's purchases minus closing stock is what left the shelves. Value it at current purchase prices, not last quarter's — a count valued on stale prices understates usage exactly when suppliers are climbing.
- 4
Act: pars, orders, and the waste log
The count's output is decisions: par levels per item (enough to reach the next delivery, no more), orders built from actual usage instead of habit, and a waste log for what you counted out — spoilage, over-prep, comps — so 'usage' stops hiding 'waste'.
Variance: where the count earns its keep
Compare actual usage to what your sales say you should have used (sales mix × recipe quantities) and you get variance — the gap between what left the shelves and what was sold. Industry studies find kitchens typically run 3–5% between theoretical and actual food cost (Restaurant365, MarginEdge), and a bar can lose up to 20% of its liquor stock to uneven pours and unrecorded comps (Sculpture Hospitality).
On a 5–10% net margin, that gap is 30–50% of profit — and the inventory count is the only instrument that measures it. A venue that counts weekly sees the leak while it's still a trickle; a venue that counts quarterly reads about it on the P&L.
Counts that don't need a Sunday
methodus keeps the whole loop — count, history, pars, orders — in one place, on phones:
Count by section, on a phone
Sections mirror your storage — walk-in, dry store, bar back — and the team counts shelf-to-screen. No clipboard, no retyping into a spreadsheet afterwards.
Count history you can compare
Every count is archived. Week-over-week movement per item is a glance, not an archaeology session in old spreadsheets.
Par levels, kept honest
Par optimization for bar and kitchen: par levels per item, reviewed against what the counts actually show — not what the order guide said last year.
Orders suggested from usage
Order forecasts propose quantities from real usage and pars, so the Tuesday order stops being a copy of last Tuesday's guess.
The count feeds the pars, the pars feed the orders, and the same purchase prices that cost your recipes value your stock — one loop, no double entry.
Variance only means something against real recipe costs. If those are stale, start with how to cost a recipe → — and keep an eye on your par level →.
Restaurant inventory FAQ
A full count weekly at minimum, with high-value and highly perishable items counted more often — daily in high-volume bars for key bottles. Always count at the same moment (before opening or after closing) so week-to-week comparisons hold.
Usage = opening stock + purchases − closing stock, valued at current purchase prices. Divide usage by sales over the same period for actual food cost percentage. Comparing that to your theoretical food cost (from recipe costs and sales mix) reveals the variance.
Variance is the gap between what actually left your shelves (measured by counts) and what your sales say should have left (sales mix × recipe quantities). Kitchens typically run 3–5% (Restaurant365, MarginEdge); bars can lose up to 20% of liquor stock (Sculpture Hospitality). It's waste, over-portioning, unrecorded comps and errors — made visible.
A par level is the target quantity to hold for an item: enough to cover usage until the next delivery, plus a small safety margin, and no more. Pars turn ordering into a subtraction — par minus current stock — instead of a guess, and keep cash from sleeping on the shelves.
A spreadsheet can hold a count, but it can't keep purchase prices current, compare counts over time without manual work, or connect the count to pars and orders. That's the double entry that makes teams abandon inventory. methodus counts by section on phones, archives every count, and suggests orders from real usage — 14-day free trial.
