The foundation

Price tracking starts with what you actually paid.

When you buy the same items every week, a few cents of silent creep on beef, packaging, or produce can add up faster than a spreadsheet catches it. The invoice is the line-item evidence—not last quarter's quote or a remembered price.

Operators often begin by comparing PDFs side by side or logging changes in a workbook. That works until invoice volume grows and product names, units, fees, and discounts stop lining up cleanly.

A durable workflow turns each new bill into comparable unit-cost history, then surfaces the movements that are large enough to review, renegotiate, or reprice.

Keep the source close. A price-change number is only useful when the supplier, date, item, quantity, and invoice stay attached.

Manual or automated

Keep the method simple enough to repeat every week.

The right system is the one your team will keep current. Start manually, then automate when the checking work becomes the bottleneck.
