Profit leak is the money a restaurant loses to voids and comp abuse, food-cost variance, and labor drift — losses that hide between the systems that should catch them. Industry research puts total restaurant fraud near 4% of sales, and total shrinkage from waste, theft, and error as high as 20% of profit. Because net margins run just 3–5%, even a few points of leak can erase a profitable month.
The reason it goes unnoticed is structural. Your POS sees the void, your scheduler sees the shift, your bank sees the deposit — but nothing reads them together, so the loss that spans them has nowhere to be caught. It typically surfaces at tax time, months after the money left, when nothing can be done about it.
Catching it requires the signals to sit in one place so they can be correlated: the voids, the inventory variance, and the labor anomalies from the same shifts. That correlation is what turns “we came up short again” into “here is the pattern, here is the evidence, here is the shift to look at” — a place to investigate, never an accusation.
