Restaurant prime cost bookkeeping: deliver it weekly

Restaurant prime cost bookkeeping means the books produce one number every week: food and beverage cost plus total labor, divided by sales. Most operators want that number at or below 60 to 65 percent, and the ones who see it weekly can fix it while the week is still in progress. The books can deliver it weekly if three things are set up once: food purchases coded by vendor rule as they post, payroll posted by pay date with tips separated, and sales pulled from the POS deposits with processor fees split out.

We run an accounting firm with a lot of restaurant clients, and prime cost is the report those owners actually read. Here's how the bookkeeping has to be built so that report is real and weekly rather than approximate and monthly.

Why 60 to 65 percent is the line

A restaurant's costs fall into two buckets it can control week to week (food and labor) and one it mostly can't (occupancy, insurance, loan payments, equipment). Prime cost is the controllable bucket as a share of sales. Above 65 percent, there's usually not enough left after rent and debt service for the owner to take a reasonable draw. Below 60 percent, either the concept has pricing power or something is being under-counted, and it's worth checking which.

The reason it has to be weekly is that a restaurant's fixes are weekly. Scheduling is weekly. Ordering is weekly. Menu pricing can change any day. A monthly prime cost that arrives on the 20th of the following month tells the owner what happened seven weeks ago, which is interesting and useless. A number on Monday for the week that ended Sunday changes Tuesday's order and Thursday's schedule.

Food purchases by vendor rule

Food cost has two honest versions: purchases and usage. Usage requires a weekly inventory count, which most independents won't sustain. Purchases is what the books can deliver without the count, and for a restaurant with steady inventory levels it's close enough to steer by. When the owner does count, the inventory adjustment goes in monthly and corrects the weekly purchases figure.

For purchases to be weekly, every food and beverage vendor has to code itself. The produce supplier, the broadline distributor, the meat purveyor, the beer distributor, the liquor store: each is a payee rule, written once, that codes every invoice or card charge to the right cost line (food, beer, wine, liquor, non-alcoholic) the moment it posts. Splitting food from bar matters because the two run at very different margins and the owner needs to see which one moved.

Two complications. First, the broadline distributor sells paper goods and cleaning chemicals on the same invoice as the chicken. Those are supplies, not cost of goods, and if the client can get the invoice detail, the split is worth doing; if not, a standing percentage from a sample month is better than lumping it all in food. Second, vendors paid by check need the check image read and the payee matched, or the food line will be missing a third of its cost. That's the same roster-and-rule method we use for every check-heavy client.

Payroll by pay date, tips paid out separated

Labor for prime cost is wages, employer payroll taxes, and workers' comp for everyone who works in the building, including salaried managers. The payroll journal has to post by pay date, with the weekly figure derived from the pay period the check covers rather than the day the cash left.

Tips are the part that gets wrong most often. Tips paid out from the drawer or from cash sales are the guest's money passing through the restaurant to the server. They are not labor cost. If they're booked as wages, labor is overstated by several points and the owner cuts a shift that didn't need cutting. Credit card tips run through payroll and show up in gross wages on the payroll report; they need to be backed out of the labor line for prime cost too, since the restaurant is only the conduit.

The setup: a Tips Paid Out account (or a tips clearing liability, depending on how the POS records the sale), a rule for the checks and cash payouts to employees that go there, and a payroll journal template that posts wages, employer taxes, and tip pass-through to separate lines every run. Once the template exists, every payroll posts the same way.

POS deposits, processor fees, and delivery platforms

Sales come from the POS, not from the bank. The bank shows the processor's net deposit two days after the fact, minus fees, sometimes batched across days. If sales are booked from the deposit, revenue is understated by the processing fee (typically a couple of points) and the timing is off by a day or two, which throws the weekly cut.

The clean setup is a daily sales entry from the POS close report: gross sales by category, sales tax collected as a liability, tips collected as a liability, cash to the drawer, card to a clearing account. The processor's deposit then clears that account, and the difference is the processing fee, booked as an expense. When the clearing account doesn't go to zero, something was miscounted and the question is specific.

Delivery platforms are the same pattern at a worse margin. The platform's payout is gross orders minus its commission, which can run well above the card fee. Book the gross as sales, the commission as a separate expense line, and the owner can see what delivery is actually costing. Many owners discover the platform is a marketing expense that loses money on every order, which is a fine thing to know before renewing.

Reading the weekly number with the owner

The report is short: sales by category, food and beverage cost by line, labor by department if the payroll supports it, prime cost as a percentage, and the same for the prior four weeks. Five rows and five columns.

The conversation is about movement. Food went from 31 to 34 percent: was there a big order for a catering job that sold next week, a price increase from the distributor, or waste? Labor went from 29 to 32 percent: was it a slow week with a full schedule, or overtime covering a no-show? Each has a different fix, and the owner knows which it was because the week is still fresh.

For a firm, this is the CFO deliverable restaurant owners renew. It's one report, it arrives every Monday, and the fifteen-minute call is where the advice happens. Priced as a tier on top of the monthly close, it holds, because the owner can point to the thing they're paying for. We wrote about structuring that tier in reports that turn a firm into a CFO service.

Where the platform comes in

Woven is our product, and restaurant clients shaped a lot of it. Vendor rules code food and beverage purchases by line as they post, check-image matching against the payroll roster separates tip payouts from vendor payments, a payroll journal template posts wages, employer taxes, and tip pass-through the same way every run, and statement import ties the operating account to the bank's own PDF so nothing is missing from the cost lines. The prime cost report runs as a scheduled package off live books and lands with the owner on Monday. To see the weekly report on a real restaurant file, book a demo.
