A bakery prices from a recipe card written years ago, costs from a gut checked monthly, and produces from a forecast that's mostly yesterday plus a feeling. Every ingredient market move since the recipe card was written lands directly in margin — and in food production, margin is measured in single digits, so a 10% flour move or an untracked 4% waste rate is not a rounding error. It's the year.
1. Stale batch costing. Recipes costed at last year's ingredient prices silently donate margin on every loaf. The price list gets reviewed when a customer complains instead of when the invoice moves — the opposite order.
2. The unmeasured waste. End-of-day leftovers, failed batches, trim, and spoilage are managed by practice but almost never recorded per product. A 3-5% production waste rate is common and invisible, which means it's permanent.
3. The production guess. Bake quantities set by habit over- and under-produduce randomly by day and season. Over-production is donated to the waste line; under-production caps sales on the days that actually had demand.
An AI layer that re-costs every batch from live supplier invoices, flags products whose margin fell below threshold, and drafts the price adjustments for review. Waste logging becomes a 15-second workflow at close, so shrinkage is per-product instead of folklore. Production planning learns from sales by weekday, season, and local events — baking to a forecast that updates weekly instead of a habit that updates never. Two weeks to install against the POS and invoicing.
A bakery producing $20,000 weekly that recovers 2% of production waste keeps $20,000 a year already baked, and live recosting typically surfaces two or three products selling below true cost — repricing or retiring them is another 2-4 points of margin on everything they touched. Combined, that's the difference between a hobby that employs people and a business that compounds.
Ask what the true cost of the best-selling item is today, including the current invoice price and the measured waste rate. If the answer comes from memory rather than a report, the price list is a historical document — and customers are buying at last year's ingredient prices.

Gear note: a rubber service mat for the counter keeps the display and coffee station clean — the cheapest upgrade to a high-traffic front counter.
