Inventory waste is one of those costs that rarely shows up as a single big number — it's a few kilos of produce here, an over-order there, spoilage nobody logged. Individually small, but it adds up to a real percentage of a restaurant's food cost over a month. Here are five concrete changes that actually move that number.
1. Track wastage as its own category, not lumped into "consumption"
If your stock records only distinguish "purchased" from "used," you can't tell the difference between food that fed a paying customer and food that got thrown out. Logging waste as its own transaction type — separate from normal kitchen consumption — is the single biggest visibility change most restaurants are missing. Once waste is its own number, you can actually see which ingredients are the problem, instead of guessing.
2. Set low-stock thresholds based on real usage, not round numbers
A lot of restaurants set reorder thresholds arbitrarily — "reorder at 10kg" because it's a round number, not because it reflects how fast that ingredient actually moves. Look at your actual daily consumption for high-turnover items and set the threshold to cover your realistic supplier lead time plus a buffer, not a guess. Too high, and you're carrying excess stock that's more likely to spoil before use. Too low, and you're running out mid-service.
3. Track expiry-prone categories separately
Dairy, meat, and fresh produce spoil on a completely different timeline than dry goods and packaging. If your inventory system treats every item the same way, expiry-driven waste is invisible until it's already thrown out. Flagging perishable categories for closer tracking — and reviewing stock age for those categories specifically — catches spoilage risk before it becomes a loss.
4. Reconcile purchase orders against what actually arrives
It's easy to assume a purchase order was fulfilled exactly as ordered. In practice, short deliveries, substitutions, and quality rejections at receiving all happen — and if your stock numbers assume the full order arrived, your inventory count drifts from reality within a few weeks. Marking a PO as received should update stock based on what was actually received, not just what was ordered.
5. Review the wastage log weekly, not monthly
A monthly review catches a trend after a month of losses. A weekly review of the wastage log — even a five-minute look — catches a pattern (a supplier consistently over-delivering perishables, a prep process generating more trim waste than expected) while it's still cheap to fix.
The pattern behind all five
Every one of these comes down to the same thing: waste is manageable once it's visible, and invisible when it's mixed into general "stock movement" with no breakdown. The fix isn't a complicated process — it's making sure your inventory system records purchases, consumption, and waste as genuinely separate, reviewable categories from day one.
OutletOps' inventory management tracks stock transactions by type — purchase, consumption, and waste — with configurable low-stock alerts and expiry tracking for perishable categories, so this kind of visibility doesn't require a separate spreadsheet.
