Food waste and spoilage should be tracked separately from regular food usage so you can see what’s being used productively versus what’s being thrown away. The accounting treatment is straightforward, but the tracking discipline is what actually helps you reduce waste over time.

From an accounting perspective, food waste is part of your cost of goods sold. When inventory spoils or gets thrown out, it still represents food you purchased. The cost reduces your inventory and increases your food cost for the period. You’re not creating a separate waste expense on your income statement. It flows through COGS like any other food usage.

The key is tracking waste separately so you know how much of your food cost comes from productive use versus loss. Set up a daily waste log where staff record what gets thrown out and why. Separate categories matter here. Prep waste includes trimmings and unusable portions. Spoilage covers expired product. Overproduction means cooked food that doesn’t sell. Customer returns are their own category. Each type points to different operational issues you can fix.

Update your inventory system when waste occurs. If you dump $50 worth of expired produce, reduce your produce inventory by that amount. At month end, your inventory count should already reflect what’s been used and what’s been wasted. If your counts consistently show more shrinkage than your waste logs explain, you have a tracking gap or a theft problem.

Calculate your waste as a percentage of food purchases. Most well-run restaurants target 2 to 5 percent waste. Higher than that indicates ordering issues, storage problems, or menu items that aren’t selling. Track by category to pinpoint where the problem lives. High spoilage means you’re ordering too much or not rotating stock properly. High overproduction means you’re prepping more than demand supports.

The waste tracking data feeds into better purchasing decisions. If you consistently throw out lettuce on Sundays, adjust your Thursday order. If a particular protein spoils regularly, either reduce par levels or find a backup use for it before it expires. This is where tracking pays off because you can’t fix what you don’t measure.

Many food businesses track waste inconsistently or not at all, then wonder why their food cost percentage runs higher than expected. Scottsdale bookkeeping services that understand food cost accounting can help you set up tracking systems that give you visibility into where your money actually goes. The goal isn’t just accurate books but actionable information that helps you run a tighter operation.
