Restaurant Bookkeeping 101: Track Food Costs, Labor & Profit the Right Way
Last updated: July 25, 2026 · Reviewed by the MenuPricer Team
Most restaurant owners understand food — they do not always understand numbers. This guide explains restaurant bookkeeping in plain terms: what accounts you need, which ratios to watch, and how to read your P&L so you always know if your restaurant is actually making money.
Why Restaurant Bookkeeping Is Different
Restaurants have a more complex cost structure than most small businesses. You are dealing with:
Perishable inventory
Must be tracked weekly or daily, not monthly
Complex labor
Tipped employees, split shifts, seasonal swings
High transaction volume
Hundreds of daily transactions to reconcile
Industry-specific ratios
Food cost %, prime cost %, covers per labor hour
Restaurant Chart of Accounts
A chart of accounts is the list of categories your bookkeeping system uses. Here is a standard restaurant setup:
How to Track Food Cost Correctly
Most restaurants make one critical mistake: they use purchases as food cost. The correct formula accounts for inventory:
True Food Cost Formula
Food Cost = Opening Inventory
+ Purchases
– Closing Inventory
= Cost of Goods Sold (COGS)
If you bought $5,000 in food this week but your closing inventory is $800 higher than your opening inventory, your actual food cost is $4,200 — not $5,000. Taking weekly inventory counts is the only way to know your true cost of goods sold.
Practical Weekly Inventory Process
- Count all inventory before deliveries on the same day each week (Sunday morning works well)
- Record quantities by category: proteins, dairy, produce, dry goods, beverages
- Multiply quantities × cost per unit = total inventory value
- Apply the COGS formula above
- Divide COGS by that week's food revenue = food cost %
Key Restaurant Financial Benchmarks
| Metric | Formula | Target | Warning |
|---|---|---|---|
| Food Cost % | Food Cost ÷ Food Sales | 28–35% | >38% |
| Beverage Cost % | Bev Cost ÷ Bev Sales | 18–24% | >28% |
| Labor Cost % | Total Labor ÷ Total Sales | 25–35% | >38% |
| Prime Cost % | Food + Labor ÷ Sales | 55–65% | >70% |
| Rent % | Rent ÷ Sales | 5–8% | >10% |
| Net Profit Margin | (Revenue - All Expenses) ÷ Revenue | 6–9% | <3% |
6 Common Restaurant Bookkeeping Mistakes
✗ Using purchases as food cost instead of COGS
✓ Do weekly inventory counts and use the Opening + Purchases - Closing formula
✗ Not separating food and beverage cost categories
✓ Track food, non-alcoholic beverages, and alcohol in separate accounts — each has different margin targets
✗ Tracking labor as one line item
✓ Separate kitchen labor from FOH labor — they have different cost targets and solutions when high
✗ Reconciling books monthly instead of weekly
✓ Reconcile sales daily, inventory weekly, full P&L monthly — problems compound fast in food service
✗ Not accounting for comps, voids, and waste
✓ Track comps and voids in your POS and record them as a separate expense category, not a reduction in revenue
✗ Mixing personal and business finances
✓ Separate bank accounts from day one — commingled finances make bookkeeping nearly impossible and create tax liability
Pricing Is the Upstream Lever

How do restaurants do bookkeeping?
Restaurants use either a bookkeeper, an accountant, or accounting software (QuickBooks, Restaurant365, or even a spreadsheet) to record daily sales, categorize expenses by type (food cost, labor, rent, utilities, etc.), reconcile bank accounts, and generate a weekly/monthly profit & loss statement. The key difference from other businesses is that restaurants must track food cost separately from other expenses, and account for inventory change when calculating true cost of goods sold.
What is a good food cost percentage for a restaurant?
A good food cost percentage is 28–35% of revenue for most full-service restaurants. Fast casual targets 28–32%. Fine dining can run 25–30% because of higher menu prices. Food trucks and takeout concepts often target 30–35%. If your food cost is above 38%, you either have a pricing problem, a waste/theft problem, or both. Track it weekly, not just monthly.
What is prime cost in restaurant bookkeeping?
Prime cost is food cost plus labor cost combined — it is the two largest controllable expenses in any restaurant. The formula is: Prime Cost = Cost of Goods Sold + Total Labor Cost. Target prime cost of 55–65% of revenue. If your prime cost exceeds 70%, the restaurant is unlikely to be profitable after fixed overhead (rent, utilities, equipment). Prime cost is the single most important number to track weekly.
How often should a restaurant reconcile its books?
Sales and cash should be reconciled daily. Food cost should be tracked weekly (via inventory counts). A full profit & loss statement should be reviewed monthly. Quarterly reviews should compare against budget targets and prior year. Annual taxes and financial statements require a certified accountant. Daily reconciliation is especially important in restaurants because small daily variances compound quickly — a $20/day cash discrepancy is $7,300/year.
