UnitProof
Per-unit identity for Shopify.
Shopify knows the product, the variant, and how many you have. It does not know this one — the particular bike, camera or guitar in front of you. So when a customer comes back about one specific item, there is nowhere for that to land.
UnitProof gives every physical item its own record.
What it does
- Its own number
-
Issue each item an identifier in a format you define —
UP-000148, a check digit, whatever your labels already use. Or import the numbers that are printed on your stock today. - Its own history
- Sold, returned, serviced, refurbished. Every entry is added, never edited or deleted, so what you end up with is a record you can actually show someone.
- Filled in while you pack
- Assign a unit to an order line from the order page in Shopify admin, scanned or typed, at the moment it goes in the box — not re-keyed into a separate tool afterwards.
What it is for
Warranty claims on a specific unit. Second-owner and resale enquiries. Showing that an item is the one it claims to be.
EU battery passports. From 18 February 2027, batteries for light means of transport — e-bikes, e-scooters, e-mopeds — need a per-item record accessible to the person holding the battery.
This is in development. There is no public release yet, and this page is not a waiting list.
I am speaking to merchants who deal with individual units every day — before building much more of it. If that is you, I would genuinely like to hear how you handle it now, and what breaks. A two-line reply is useful; fifteen minutes is better.
