Solutions
Whatever you sell and wherever you sell it, the need is the same: a number for every product, a barcode that scans first time, and a record you can show to anyone who asks whose product it is.
Retail and FMCG
Give every pack size and flavour its own barcode so that it rings up correctly at the till and your stock counts stay right.
Manufacturers
Number your consumer units, inner packs, cases and pallets, and record which contains which, so that goods can be traced from the line to the shelf.
Warehouses and logistics
Print carton and shipping labels with the barcode, batch and dates your receiving staff scan at the dock.
Online sellers and exporters
Keep one list of products with their barcodes and export it whenever a marketplace or buyer asks for it. Check first whether your marketplace requires GS1-issued numbers.
Small businesses
Start with a small plan, add products as you grow, and move to a larger plan when you need more barcodes.
