Unit prices, without the spreadsheet
UnitProof finds the variants in a Shopify catalog whose price per kilo, litre, metre or item is missing or wrong, works out the right measurement from what the store already knows, and writes it in bulk once you have seen exactly what will change.
- It reads the catalog you have. Package sizes come from variant options, titles and shipping weight — a 500 g bag is recognised as 500 g, and a title saying six bottles of 0,33 l adds up to 1.98 l.
- Nothing changes until you agree. Every bulk write is previewed row by row, before and after, and anything the app is unsure about waits for you rather than guessing.
- Any change can be undone. Each run is recorded with the values it replaced, so a run can be rolled back for 30 days — including one that was our mistake, which is never charged for.
- It writes to Shopify's own fields. The figure appears wherever your theme already shows a unit price, in the currency each shopper sees. No theme edit, and no data left behind if you uninstall.
