Retailers
Pull supplier data cleanly into your ERP. Instead of building a custom export path for every manufacturer, speak VeloConnect + BIDEX once — and map product groups onto the structure you already have.
Open Source · VeloConnect Server
Your own VeloConnect server.
VeloStack is an open-source VeloConnect server for both sides of bicycle specialist retail: for retailers pulling supplier data into their ERP — and for manufacturers and suppliers publishing their own catalog to a standard. One tool, two directions.
Who it's for
Manufacturers · Suppliers
Publish your own catalog to a standard: models with variants, BIDEX product groups, EAN-compliant item IDs. Retailers integrate it directly into TriData, Velo.Port and other ERPs — no more maintaining a custom format per ERP.
