Backroom Labels: Barcode Audit

Two products with the same barcode look identical to a POS scanner. The register rings up the wrong item, the wrong unit leaves inventory, and the gap surfaces weeks later at a stock count.The audit reads every variant and reports each barcode held by more than one product, grouped by the products that overlap. It exports as CSV and writes nothing.The repair rewrites only generated codes, never a supplier UPC or EAN. You approve every change, and any run can be undone.
