How often should a restaurant owner review their books and what reports matter most?
Weekly reviews are the bare minimum for restaurants because margins are thin and costs shift fast. Food cost and labor cost are the two numbers that make or break a restaurant, and waiting a full month to check them means you’ve already lost money you can’t get back.
Every week, look at three things. Food cost percentage should land between 28% and 35% of revenue depending on your concept. Labor cost percentage should fall between 25% and 35%. And daily sales trends should show you where demand is shifting. If Thursday dinner traffic has dropped three weeks in a row, you can adjust staffing or run a promotion before it becomes a month-long drag on labor efficiency. These weekly checks take maybe 30 minutes and they prevent small problems from compounding into big ones.
Monthly is when you pull the full picture. Your profit and loss statement shows overall performance across every category. But the most important number on it is prime cost, which combines food and labor into a single figure. Prime cost should stay under 65% of revenue. If it’s above that, you’re probably not making money regardless of how busy the dining room looks.
Also monthly, review your accounts payable aging report. This tells you which vendor invoices are outstanding and whether you’re at risk of late fees or losing early-pay discounts. Review your cash flow to make sure you can cover upcoming obligations like rent, loan payments, and quarterly tax deposits. Surprises in cash flow are the kind of problems that close restaurants.
Compare every month to two things: your budget and the same month last year. Budget comparison shows whether you’re hitting your targets. Prior year comparison accounts for seasonality. December always looks different than March, so comparing consecutive months can be misleading. When actual results are off from both budget and prior year, that’s a strong signal something changed and needs attention.
One more benchmark worth tracking is occupancy cost, which includes rent, property taxes, and insurance. This should run between 6% and 10% of revenue. Above 10% usually means you’re either paying too much in rent or not generating enough sales from your space.
The restaurants that struggle financially usually aren’t the ones with bad food. They’re the ones where the owner checks the books once a quarter or only when the bank account feels low. By then, a 2% food cost creep has already eaten thousands of dollars. Working with bookkeepers in Buena Park who understand restaurant operations means these numbers land on your desk on schedule, formatted in a way that actually helps you make decisions before small leaks become serious problems.
