Why EDI with Retailers is Mandatory
Top retailers (Carrefour, Auchan, Kaufland, Mega, Profi, Selgros, Cora) require standardised EDI: ORDERS, ORDRSP, DESADV, RECADV, INVOIC, REMADV.
Without EDI: chargebacks of 1-3% of invoice value, payment delays, SKU delisting, and losses of €20-60k/year for high-volume manufacturers.
Native Capabilities in Nexus
Nexus includes partial EDI: generation of standard INVOIC files, manual ORDERS import, and basic per-retailer mapping requiring significant configuration effort.
Limitations: lack of pre-built per-retailer mappings, setup taking 5-15 days per retailer, and continuous maintenance required for specification changes.

Option 1: External EDI Broker
Setup: €5-12k/retailer + €200-500/month
Pro: the broker manages specification changes
Con: fragmented per retailer, no unified dashboard
