Prime cost is not a month-end surprise. If you wait for the P and L, you already missed the week you could have fixed. restaurant prime cost is cost of goods sold plus total labor as a percent of sales, and the operators who stay in range run a weekly cadence, not a quarterly postmortem.

Set a Band, Then Protect It Every Week

Most independent full-service restaurants aim for 60–65% of sales. Fast casual often lands in the mid-50s to low-60s. QSR can run lower on labor if throughput is tight. The exact target matters less than the rhythm: same meeting, same four numbers, every week.

A 2-point miss on $80,000 weekly sales is $1,600 that week. Annualize it and you are staring at real rent money. Food and labor move inside seven days. A bloated Saturday schedule, a bad produce week, and an unlogged waste spike will not wait for your accountant.

Monday Recap

Pull last week's sales, theoretical food cost, actual invoices, labor hours, and overtime. Compare to the target band for the concept. Do not debate the formula in this meeting. Debate the variances.

·         Sales versus forecast by daypart, not just by day.

·         Labor hours versus the schedule you published, including training and side work.

·         Invoice total versus what the order guide said you should have bought.

·         Waste, comps, and discounts that never hit a recipe.

Name one food action and one labor action before anyone leaves. "Look into chicken" is not an action. "Cut the Tuesday closer by two hours and switch to 8-piece on the feature" is an action. Do this recap before you place the next protein order.

Schedule Versus Sales

Build next week's schedule from a sales forecast, not from last year's template. If lunch is 32% of sales, do not staff like dinner. If Monday night is dead, do not run a full dish pit for morale.

Use a simple check: projected labor dollars divided by projected sales. If that number is already above target before the week starts, you are planning to miss. Cut shifts now, not after Thursday overtime. Watch salary creep. Managers covering FOH gaps look like "no extra labor" until you count the ordering, coaching, and invoice work that did not get done.

Split shifts and mid-shift cuts are uncomfortable. They are also how you keep labor inside the band when the forecast was wrong. Publish a sales-to-labor cheat sheet so the closer can cut without waiting for a text from the owner.

Invoice Audit

Every week, audit the invoices that hit during the recap week. Check price against contract, quantity against what was received, and credits against shorts. Catch the $0.40/lb chicken bump before it sits in food cost for a month.

Split the work. The kitchen manager owns protein and produce. The GM or bookkeeper owns beverage, paper, and chemicals if those sit in COGS. Flag substitutions. A "comparable" fish that costs $2 more per pound is not comparable. If you do not weigh in high-cost items, the audit is theater.

Waste Log as a Control, Not a Clipboard

If the waste log is empty, it is a lie. Require spoilage, trim overage, overcook, and walk-outs to be logged with a reason code. Review the top three items in dollars, not in pounds. Five pounds of herbs is not the same as five pounds of ribeye.

Comps and discounts belong in the same conversation. They are not marketing when the line is 86ing steaks because the par was wrong. Pair the waste log with theoretical versus actual food cost so you can see whether the leak is prep, the line, or the back door.

A Simple Weekly Scoreboard

Post four numbers in the office where the team can see them:

·         Food cost percent (actual versus theoretical).

·         Labor cost percent, including taxes and benefits, not just wages.

·         Prime cost percent versus your band.

·         Waste plus comps in dollars for the week.

When restaurant prime cost sits above band for two weeks, stop looking at the menu first. Look at hours, purchasing, and waste. Menu engineering is slower. Scheduling and receiving are this week's levers.

What "In Range" Actually Means

Pick a band, not a single number. A banquet-heavy week will look cheap on labor and expensive on food. A storm week will crush sales and explode labor percent. Judge the week against the volume you actually did, then judge the four-week rolling average against the annual target.

Prime cost does not include rent, marketing, or loan payments. Those still matter. They just do not belong in this meeting. If occupancy is the real problem, no amount of Monday recaps will save a site that cannot do the sales. That is a location and lease issue, and it is one reason the restaurant failure rate stays stubborn for operators who only watch the kitchen.

Cadence a Small Team Can Run

You do not need a corporate analyst. You need 45 minutes on Monday, an honest waste log, and a schedule that matches the forecast. Do the recap before the protein order. Do the labor cut before you publish the schedule. Operators who keep prime cost in range are not better at math. They are better at repeating the same four checks every week until the misses get smaller.
