How to switch EDI providers
Switching EDI providers feels risky because a dropped document can mean a chargeback. Done methodically, though, a migration is low-risk: the key is to test new connections in parallel before you cut over, so nothing goes dark.
1. Inventory your trading partners and documents
List every retailer and partner you trade with, the exact transaction sets each requires (850, 856, 810, 940/945, etc.), connection methods (AS2/VAN/SFTP/API), and any labeling rules. This inventory is the spec your new provider has to match.
2. Re-map and validate
Your new provider rebuilds the document maps for each partner. Validate them against real historical documents so you catch format differences before go-live. Pay special attention to ASN (856) structure and GS1-128 labels, which are the most chargeback-prone.
3. Test in parallel, then cut over
Run the new connections alongside the old ones and exchange test documents with each partner (many retailers require re-certification). Once a partner is validated, cut it over. Migrate partner-by-partner rather than all at once, so any issue is contained.
4. Monitor closely after go-live
Watch 997 acknowledgments and any compliance dashboards for the first few weeks to catch rejects immediately. With EndlessEDI, EDI moves onto the same source of truth as inventory and orders — and most brands go live in hours, not a multi-month project — so monitoring and exception handling live in one place.
FAQ
Will switching EDI providers cause chargebacks?
Not if you test in parallel and re-certify with each retailer before cutting over. The risk comes from cutting over without validating maps and connections first. Migrating partner-by-partner contains any issue.
How long does an EDI migration take?
It depends on partner count and re-certification requirements. Mapping and testing are the gating steps. Native platforms like Endless shorten setup, but retailer certification timelines still apply.
