Supplier price rises are eating my café's margin and I only see it at BAS time

How to catch supplier price changes the week they happen, from the invoices you already receive, and push them into menu pricing before a quarter of margin is gone.

Short answer: file every supplier invoice as it arrives, compare unit prices to the last order, and flag any rise the same week. Then decide: absorb, substitute or reprice. Most venues find two or three rises a month they didn't know about.

Why it hides

Invoices go to the bookkeeper's folder. The total looks normal because volume moved. The unit price of milk, coffee or chicken went up 6 percent and nobody compared.

The flag

Supplier invoices filed by the inbox module or by hand; unit prices compared to the last invoice from the same supplier; rises listed with the annualised cost at your volume; menu items that use the line flagged for a price review.

The decision

Absorb it (rarely), substitute the product, negotiate with the supplier (the history is now in front of you), or reprice the menu item. The morning check carries the flag; you make the call.
