Part of the Odoo Pro EXTREME (Edycja PERP) family by Nexus Digital. Generate correct GS1 barcodes on product creation and in bulk for existing catalogues — random or sequential, with an optional prefix and a global uniqueness guarantee.
New products without a barcode receive a valid one automatically. One toggle in Settings turns it on or off.
From the Products list: Action → Generate barcodes (PERP). Fill only the empty ones, or overwrite everything — your choice.
Correct check digit every time. EAN-13 is the PL/DACH retail standard; UPC-A is available for North-American workflows.
Pick deterministic numbering backed by an Odoo sequence, or random codes. Add an optional numeric prefix for internal ranges.
