Restaurant bookkeeping has one high-frequency point of failure, and it is not the month-end close. It is the daily sales entry — the journal entry that translates yesterday's point-of-sale report into the accounting file.
It happens 365 times a year. An error in its structure repeats 365 times before anyone notices.
What the POS report contains
The daily summary is not a revenue figure. It is a bundle of several distinct things that happen to arrive together:
- Net sales — food, beverage, and any other categories, ideally split.
- Sales tax collected — never yours. A liability from the moment it is collected.
- Tips — the staff's money. Also a liability until paid out.
- Comps, voids, and discounts — contra-revenue, not expenses.
- Tenders — how it was paid: cash, cards, gift cards, delivery apps.
The entry has to split all of these. Collapsing them into a single revenue line is the mistake, and it is a common one.
What each error actually does
Tips booked as revenue. Sales inflate by the full tip amount. Food cost as a percentage of sales drops artificially, so the one number a restaurant manages most closely becomes flattering and wrong. Then the tip payout gets recorded as an expense, so both sides of the P&L are overstated.
Sales tax booked as revenue. Same inflation, plus a liability that never gets recorded. When the return comes due, the amount owed does not tie to anything in the books.
Comps treated as expenses. A comped meal is revenue you chose not to collect, not a cost you incurred. Recording it as marketing expense overstates both sales and expenses, and hides the comp rate — which is a number worth watching, since it drifts upward quietly.
Gift cards
Selling a gift card is not a sale. It is a liability — you owe someone a meal. Revenue is earned when it is redeemed.
Restaurants that book gift card sales as revenue post a strong December and then a mysteriously weak January, when redemption produces food cost with no corresponding sales. The liability also matters because unredeemed balances accumulate, and in most states they are subject to escheat rules.
Delivery platforms
The deposit from a delivery app is net of commission, which commonly runs 15–30%. Booking the deposit as revenue understates sales and hides the single largest variable cost in that channel.
It is worth tracking delivery as its own revenue category with its own commission expense. Plenty of operators discover that a channel they assumed was incremental profit is running at or below break-even once commission and packaging are counted honestly.
Making the deposits tie
The card portion of yesterday's tenders will not appear in the bank as one matching figure. It arrives a day or two later, net of processing fees, sometimes batched across days.
So there are two reconciliations: the daily entry has to tie to the POS report, and the card tenders have to tie to processor deposits with fees broken out. When both hold, you can trust the sales figure. When neither is done, the numbers are an estimate that happens to be printed on official-looking paper.
Getting it right once
The good news is that this is a setup problem more than a daily-effort problem. Once the entry template is built correctly, the daily work is mechanical.
We build that template as part of restaurant bookkeeping, and how prepared food is taxed varies significantly by state — which is why those guides run state by state rather than as one page.
