EDI integration — connecting EDI to your ERP, WMS and TMS
In short: EDI integration is the process of wiring an EDI platform to your internal systems (ERP, WMS, TMS, e-commerce) so orders, shipments and invoices flow automatically between trading partners and your applications. This guide covers integration patterns, connectors, and how EDI compares to API-based B2B integration.
Key capabilities
- Native ERP connectors: 40+ ERPs: SAP, Microsoft Dynamics 365, Oracle NetSuite, Odoo, Sage, WinMentor, Charisma, Senior, Clarvision.
- REST API: Modern JSON API for custom integrations. Webhooks for real-time push into your system.
- File-drop interface: SFTP or shared folder for legacy ERPs — drop CSV/XML in a folder, we pick it up and translate.
- Multi-system orchestration: Split incoming ORDERS across ERP + WMS; consolidate DESADV from WMS + INVOIC from ERP.
- Bi-directional real-time sync: Inventory (INVRPT) and catalog (PRICAT) synced continuously, not batch nightly.
- Monitoring & retries: Failed integrations retry with backoff, alert your team on persistent errors, keep audit trail.
EDI integration patterns
Three common EDI integration patterns:
- Direct-to-ERP: EDI platform pushes documents straight into ERP via native connector. Fastest, cleanest, requires supported ERP.
- Staging + ETL: EDI platform writes to staging tables or files; ETL job loads into ERP nightly. Legacy ERPs, batch tolerance.
- Event-driven with API middleware: EDI events trigger webhooks; middleware (MuleSoft, Azure Logic Apps) routes to multiple systems.
Frequently asked questions
What is EDI integration?
EDI integration is the technical work of connecting an EDI platform to your internal business systems (ERP, WMS, TMS, e-commerce) so that documents received from trading partners flow automatically into the right internal application, and documents generated internally are automatically sent out via EDI. Without integration, EDI is just a portal with manual copy-paste.
How to integrate EDI with SAP?
For SAP (S/4HANA, ECC or Business One), the cleanest path is using SAP's IDoc interface. The EDI platform receives EDIFACT/X12, converts to IDoc, and posts to SAP via RFC or SAP PI/PO. EDIconnect ships a native SAP IDoc connector.
How to integrate EDI with NetSuite?
NetSuite integration uses SuiteScript or the SuiteTalk REST API. The EDI platform posts sales orders (from EDI 850/ORDERS) directly into NetSuite, and reads item fulfillments and invoices back out. EDIconnect has a certified NetSuite connector.
How to integrate EDI with Microsoft Dynamics 365?
Dynamics 365 Business Central and Finance & Operations both expose OData REST APIs. The EDI platform posts sales orders, reads shipments, and posts vendor invoices via these APIs. Setup takes 2-5 business days.
EDI vs API for B2B integration — which is better?
Neither replaces the other. EDI is the standard for asynchronous, high-volume B2B document exchange with defined semantics (EDIFACT ORDERS = purchase order, universally). REST APIs are best for real-time, interactive integrations (stock check, pricing). Modern EDI platforms expose both: EDI for partner-to-partner, REST API for platform-to-your-ERP.
What is API and EDI integration?
It's a hybrid pattern: EDI handles the partner-facing side (retailer sends ORDERS via AS2), while REST APIs handle the inside-your-company side (posting into ERP, pulling out invoices). This gives you the standardization of EDI outward and the flexibility of APIs inward.
