Brasa Demo is a fictional burger restaurant. Figures are illustrative.

The price per kilo went up.
Nobody said a word.

The problem

One Monday the ground beef arrived at $169 a kilo. The week before it cost $148.

The usual

The shift lead signs in a hurry, the receipt goes into the bag, and the increase shows up three months later, in the menu price.

What fixed it

Purchasing compared the invoice against the market that same night. By 9:00 there was a card.

$17,238in one quarter
Brasa uses 78 kg of beef a week. Of the $21 increase, $4 was the market and $17 was negotiable: $1,326 every week nobody compares. One location, ~520 checks a week, $260 average check. Amounts in Mexican pesos.

Tuesday, 9:00. Yesterday's beef is already compared.

On Monday at 16:10 the shift lead recorded the delivery and attached the invoice. That night AventarIA set it next to last week's price and today's price at five stores.

Without that card, your customer ends up paying the increase.

The supplier hid nothing: the new price was on the invoice. The problem is that nobody has time to read it against the last one.

Monday
The beef arrives in the middle of prep. The shift lead signs the delivery note standing up, with the order queue behind him.
Friday
The receipt goes into the bag with the rest. The bag goes to the accountant.
Month end
Food cost went up more than a point. Everything is just more expensive.
Month 2
The owner blames the kitchen for the portions. The kitchen is serving the same 120 g as always.
Month 3
The classic goes from $149 to $159. Customers pay an increase nobody negotiated.

Cost of the classic, at the new price

The $4 the market really rose does not go away. On receiving, recipe cost updated: the classic costs $0.48 more and its margin over ingredients went from 71.2% to 70.9%. If the owner raises the price, she decides with that number. A ten-peso increase was never needed.
