EDI in B2B document exchange
Electronic Data Interchange (EDI) remains the dominant B2B document-exchange standard for purchase orders, invoices, advance ship notices, and related transactional documents. Despite newer API-based alternatives, EDI is still required for trading-partner relationships with most large retailers, distributors, and manufacturers.
How Thoughtwave integrates EDI
Our engagements cover:
- X12 (ANSI) EDI for U.S. trading partners covering the common transaction sets (850 PO, 810 invoice, 856 ASN, 997 acknowledgment).
- EDIFACT for international trading partners.
- EDI via value-added network (VAN) or AS2 direct-connection depending on the trading partner.
- Integration with TWSS AI PO Agent for clients where EDI-received POs flow into the AI order-capture workflow alongside email and portal ingest.
- Trading-partner onboarding for clients expanding EDI relationships.
Authentication and compliance
EDI integration runs through the client's VAN provider, AS2 direct connection, or trading-partner-specific arrangements. Compliance with trading-partner spec variations is the integration work that typically consumes most of the project time.
Why EDI persists
For large retail and distribution trading-partner relationships, EDI remains a contractual requirement. Our engagements deliver EDI integration alongside modern API-based patterns so clients can trade with both EDI-era and API-era partners from a unified integration layer.
