Restaurant food waste is not one problem, it is five, and they have different fixes. Measure first — a stock count and a variance report tell you where your waste actually is — then work the biggest source.

Over-ordering

Buying more than you will use before it spoils. Fix: order to a par level based on real sales velocity, not a habit. Shorten the order cycle for perishables — smaller, more frequent deliveries waste less than one big one.

Prep waste

Trim, peel and offcuts that go in the bin. Fix: record it. Prep waste that is never weighed is never managed. Once it is visible, yields go into your recipe costs and some of it turns into stock (bones to stock, trim to staff meal).

Spoilage

Stock that goes off before it is used. Fix: rotate properly (first in, first out), label with dates, and count often enough to catch slow movers before they turn. A weekly count of perishables surfaces the items you consistently over-buy.

Over-portioning

Plates going out heavier than the recipe. This shows up as a widening stock variance on specific ingredients with no matching sales. Fix: scale the station, re-train, and re-cost the recipe to what is actually being served so at least your pricing is right.

Plate waste

Food coming back uneaten. Fix: look at which dishes and which portion sizes come back most. Sometimes the answer is a smaller portion at a lower price, sometimes it is a dish that should be retired.

How software helps

The measurement is the hard part. With recipes linked to sales, Restovax shows theoretical usage against counted usage per item, so waste and over-portioning show up as a number rather than a hunch. You still fix it in the kitchen — the software just tells you where to look.

Do not chase all five at once. Measure, find your biggest source, fix that, then re-measure. Waste that is counted shrinks; waste that is guessed at does not.
