How to Catch Supplier Price Increases Before They Eat Your Margin

Your chicken thighs went from $2.89/lb to $3.19/lb. Doesn't sound like much, right? If you use 200 lbs a week, that's $60 more per week — $240 per month — that just vanished from your bottom line. And most owners don't catch it for weeks because nobody is reading every line on every invoice.

Why it slips through

Supplier invoices are long, dense, and arrive when you're busy. You glance at the total, make sure it's in the ballpark, and move on. The per-unit prices buried in 30+ line items? Nobody has time to cross-reference those against last month's invoice.

The compounding effect

One price increase is manageable. But suppliers don't raise one item at a time. Over a quarter, you might see 5-10 items creep up by 5-15% each. Combined, that can shift your food cost by 2-3 percentage points — the difference between profitable and not.

What to do about it

The answer isn't spending an hour every week comparing invoices. It's having a system that does it for you. Track per-unit prices over time so you see the trend. Flag increases immediately so you can renegotiate, adjust portions, or raise prices while the margin still exists.

How Expo handles it

Text a photo of any supplier invoice to Expo. It reads every line item, logs the per-unit price, and compares it to previous invoices. When something goes up, you get a message: "Your chicken thighs went from $2.89/lb to $3.19/lb — that's a 10.4% increase." No spreadsheets. No manual tracking. Just a photo and an alert.
