How are unit prices calculated?

Unit prices are calculated by dividing the total cost of a purchase by the quantity provided in the record, normalized to the product's standard unit of measure.

Can I compare prices between different stores?

Yes, you can use the `get_store_price_comparison` tool to see the average unit prices for a product across all stores in your ledger.

How do I find the cheapest price ever recorded for an item?

You can use the `get_best_known_price` tool to identify the lowest historical unit price recorded for a specific product ID.

An AI recommended '$29/month per seat' because that is what three competitors charge. No value metric analysis — seat count has nothing to do with value delivered. No WTP research — the price was copied, not discovered. No segmentation — enterprise pays the same as a 3-person startup. No unit economics — CAC was $380 and LTV at $29/month with 14-month retention was $406. LTV/CAC of 1.07x. The company grew revenue 12% while burning 40% of cash on acquisition. This tool forces value metric definition, WTP research, segment pricing, unit economics, and packaging design.
