Restaurant Bookkeeping: POS Reconciliation, Prime Cost & Daily Sales

Restaurants Live and Die by the Margins

Few businesses run tighter than restaurants: high transaction volume, perishable inventory, tipped labor, and razor-thin margins. Bookkeeping that's "close enough" simply doesn't work — small leaks become big losses fast.

Reconcile the POS to the Bank, Daily

Your point-of-sale system reports sales, your card processor deposits cash, and your bank shows what actually landed. Those three rarely match line-for-line because of processor fees, tips, holds, and timing. Daily POS-to-bank reconciliation is what catches the gaps — a missing deposit or an unexplained fee — before they pile up into a month-end mystery.

Track Prime Cost — Your Most Important Number

Prime cost is your cost of goods sold (food and beverage) plus total labor. It's the single most-watched metric in the restaurant world because it's the biggest, most controllable chunk of your spending. Bookkeeping that cleanly separates COGS and labor lets you watch prime cost as a percentage of sales — and act the moment it drifts.

Handle Tips and Payroll Correctly

Tips, tip-outs, and tipped wages have specific reporting rules, and they flow into payroll. Mishandle them and you risk both payroll errors and compliance problems. Clean books keep tips, wages, and payroll taxes straight.

Don't Ignore Inventory

Food cost only makes sense when inventory is tracked. Counting inventory and tying it to purchases turns a guess — "food cost feels high" — into a number you can actually manage.

The Bottom Line

In a restaurant, the difference between profit and loss often hides in the details: a creeping food cost, an unreconciled processor fee, a payroll slip. Bookkeeping built for high volume and a daily rhythm is what keeps those details from sinking the month.
