Backroom Labels: Barcode Audit

This app finds products that share the same barcode and helps you fix duplicate barcode issues without affecting supplier codes. When two products have identical barcodes, your POS scanner can't tell them apart, causing the wrong item to ring up and creating inventory gaps that only show up later during stock counts. The read-only audit scans every variant in your catalogue and reports each barcode held by more than one product, grouped by overlapping items. You can export the full list as CSV for easy review and label reprinting. The repair tool only rewrites generated codes, never touching supplier UPCs or EANs. You preview and approve every proposed change before anything is written to your catalogue. Any run can be rolled back, and variants edited by someone else are automatically skipped to prevent overwrites.
