Shopify lets one variant carry up to twenty barcodes, but only one at a time, typed in by hand. A store with 500 variants and two codes each faces 500 separate edits. Shelfmark takes the whole list from one CSV file. Your file is checked against your catalogue first, and each problem is named in plain English: a code already on another product, a code given to two SKUs, a variant already at the limit, a check digit that does not match. Nothing is written until you have read that list.
