Understanding Variance Reports: 1/4 module

Understanding Variance Reports

Tambu spends the next 7 minutes pulling back the curtain on two reports that live in  almost every restaurant system — and that most people either ignore, misread, or have never been shown properly. That ends today.

What is a Prep Variance Report

Let's start with the Prep Variance Report.

Here's the simplest way I can describe it: it's the report that watches what your kitchen makes — not what it sells.

Every time your team preps something — whether that's portioning chicken, making a sauce, slicing vegetables — that prep gets recorded. The system expects a certain amount of raw ingredient to go in and a certain amount of finished product to come out.

The prep variance report tells you: did those two things match?

If your chef used 10kg of chicken to prep, the system expected 8.5kg of usable portions. Did you get 8.5kg? Or did you get 7kg? That 1.5kg gap — that's your prep variance.

It measures yield. How much of what you bought actually became something you could sell.

Why does this matter? Because every kilogram you lose in prep is money that was spent but will never come back through a sale. It's invisible — but it's real."

What is a Bulk Variance Report and how it differs

Now the Bulk Variance Report is a different animal — and this is where people get confused.

While the Prep Report watches what happens inside the kitchen during production, the Bulk Report watches what happens to your stock overall — from the moment it arrives at your back door to the moment it's been used or sold.

Think of it this way:

The Prep Report is a microscope. It zooms in on one process — 'we prepped this dish, did the numbers work?'

The Bulk Report is a wide-angle lens. It looks at the bigger picture — 'we received this much stock, we should have used this much based on sales, what's actually left?'

The Bulk Report picks up losses that prep doesn't — things like stock that went missing before it even reached the kitchen, receiving errors where you were invoiced for 20 units but only got 18, spoilage that happened in the fridge before anyone touched it, or portions that left the kitchen but never made it onto a bill.

Together, these two reports tell a complete story. One alone leaves you with half the picture.

How clearing frequency affects data accuracy

Now I need to talk  about having a courageous staff meeting.

Stop. Before you do anything, ask these three questions:

One — when did we last clear? If it was 6 hours ago and your kitchen runs 16-hour cycles, those losses aren't real yet. The cost is recorded, the revenue isn't.

Two — did we receive any stock today that hasn't been invoiced yet? Stock that arrives and gets used before the invoice is processed shows up as a loss. It's a timing issue, not a theft issue.

Three — are these losses consistent, or random? If the same three items show losses every single day, that's a pattern worth investigating. If it's different items every day, it's likely a data timing or recording problem.

Nine out of ten items showing losses almost never means nine problems. It usually means one systemic issue — either the clearing cycle is wrong, the receiving process is inconsistent, or someone isn't recording transfers between sections.

The report isn't telling you 'you have a crisis.' It's telling you 'something about the way we're capturing data needs attention.' That's a very different conversation.

We have covered the Prep Variance, the Bulk Variance and how clearing frequency can create that 90% loss scenario that isn't actually a crisis- It's a data gap.

But knowing the gap exists is only step one. To actually plug the leaks and stop that 2.6% profit bleed, you need the right framework to capture that data daily.
