Shopify issues no barcodes, so most catalogues have variants with an empty barcode field. Verkode generates them, as valid EAN-13 codes and readable SKUs, and shows you every one before writing anything. A field that already holds a code is never overwritten. Then it prints. Set the width and height in millimetres, on rolls or A4 sheets, rather than picking from a fixed list. When stock arrives, start from the shipment: quantities come from what was accepted on receiving.

• Generate valid EAN-13 barcodes and readable SKUs, previewed before writing
• Any label size in millimetres, on rolls or A4 sheets, with a PDF preview
• Scan to queue a label, or print from incoming stock by accepted quantity
