How do you catch a supplier price increase before it disappears into your food cost?
A bar manager looks at food cost on the 1st of the month. The percentage is slightly worse than it should be. Someone says "huh, weird." Nobody can say when it started or which item did it.
That is how price increases usually get found: late, by accident, after the point where it mattered.
Why the increase goes unnoticed
A supplier raises a price. The new number shows up as one line on a delivery invoice. The invoice posts, and that line gets folded into the month's food cost. Nothing marks it as different from the lines around it.
Once it is averaged in with everything else, one item that costs more is a small push on a large total. The total moves a little, and the cause is invisible. The only signal is a slightly worse percentage, and by the time anyone looks at it, the month is over.
The information was there the whole time, on the invoice. Nobody was assigned to compare it to last time.
What the fix looks like
After an invoice posts, the agent goes through its line items and pulls every one that arrived higher than last time. Then it puts that list in front of the manager before the shift starts.
The pieces are simple:
- The trigger is the invoice posting.
- The comparison is each line against what it cost last time.
- The output is only the items that went up.
- The timing is before the shift, while the manager can still do something with it.
What it deliberately isn't
There is no dashboard to open and no report to check. The manager gets a plain message: here are the things that got more expensive overnight.
A dashboard only helps if someone goes looking. This puts the answer in front of the manager at the moment it is useful. The number no longer gets to disappear into the aggregate and pretend nothing happened.
What it doesn't do
It tells the manager what changed. It does not decide what to do about it. That part stays with the manager.
It also only flags lines that arrived higher than last time. It surfaces price increases and nothing else, which is the whole point of keeping it narrow.
What to take from this
If price increases reach you as a vague percentage on the 1st, the problem is timing and placement. Compare every invoice line to last time, show only the ones that went up, and show them before the shift.
Blocking and tackling. The lemonade stand wins again.
