EDI integration connects your business systems (ERP, WMS, TMS, eCommerce, accounting) to trading partners so that purchase orders, invoices, shipping notices, inventory updates, and other documents move automatically no rekeying, no email attachments. Short for electronic data interchange, EDI uses standardized formats and secure transports to enable secure data exchange across companies at scale.
Modern supply chains run on speed and accuracy. EDI integration cuts manual steps, reduces errors, and accelerates order-to-cash and procure-to-pay cycles. It’s foundational for retailers, manufacturers, distributors, healthcare, logistics/3PLs, and marketplaces that require electronic compliance. In practice, B2B EDI integration improves fill rates, shortens lead times, and provides real-time visibility that email and spreadsheets can’t match. If you’re asked by a big-box retailer or marketplace to “go EDI,” they’re asking for what is EDI integration in action: connect, translate, transmit, confirm.
At a high level, your system generates data (e.g., a sales order) → the EDI layer maps it into a standard (e.g., X12 850) → it’s transmitted using an EDI protocol (e.g., AS2, SFTP) → your partner’s translator ingests it.
Translator & mapper (EDI software): Converts between internal formats (CSV/JSON/XML/IDocs) and standards (X12, EDIFACT, HL7). Mapping handles field-by-field logic and validations.
Communications/transport: AS2, SFTP/FTPS, OFTP2, API, or a VAN (Value Added Network). Certificates, MDNs/receipts, and retries live here.
Integration/middleware layer: The data integration software or EDI integration platform that connects to ERP, WMS, eCommerce, and databases, triggers workflows, and logs status.
Monitoring & exceptions: Dashboards, alerts, and reprocessing tools so you catch failed transmissions or invalid data quickly.
Partner profiles: Each retailer/carrier has guides (versions, segments, qualifiers). Profiles enforce those rules per partner.

Instead of pure file drops, EDI API integration exposes/consumes REST endpoints for trading or network hubs. It’s still EDI at the business-document level but moves via APIs for lower latency and tighter orchestration.
EDI integration with ERP (e.g., SAP, NetSuite, Microsoft Dynamics, Oracle, QuickBooks) exchanges master and transactional data.
Inbound: EDI 850 (PO) → create sales order in ERP; EDI 820 (remittance) → cash application.
Outbound: EDI 855 (PO Acknowledgment), 856 (ASN) with carton/pallet SSCC labels, 810 (Invoice).
Common patterns: EDI integration with SAP, QuickBooks EDI integration, and 3PL EDI integration for warehouse shipping confirmations (940/945) and inventory (846).
How many types of EDI are there? Practically three delivery models:
You connect to each partner over AS2/SFTP directly.
Pros: Full control, lower per-transaction fees.
Cons: You manage certificates, retries, and every partner’s quirks.
Route documents through a provider’s network that brokers communications.
Pros: Simplifies connectivity; mailbox model; partner onboarding help.
Cons: Network fees and some latency.
Mix direct links for key partners with a cloud EDI integration platform for everyone else. Many providers (e.g., network-based solutions similar to SPS Commerce EDI integration) bundle onboarding and testing as a service.
Orders & fulfillment: 850 PO → 855 Acknowledgment → 856 ASN → 810 Invoice
Logistics/3PL: 940/945 shipping orders/confirmations, 214 shipment status, 210 freight invoice
Inventory & catalog: 846 inventory, 832 price/sales catalog, 888/889 item maintenance
On-prem translators (EDI software): Robust mapping, runs in your data center.
Cloud EDI networks: Connectivity + mailbox + testing services (popular for retailers).
iPaaS with EDI connectors: General data integration software that also supports EDI, APIs, and event-driven flows.
EDI integration tools: AS2 servers, SFTP gateways, label/ASN pack-and-ship modules, test harnesses, and document simulators.
Choosing among EDI integration software options depends on volume, number of partners, internal skills, and compliance requirements.
Confirm requirements: Gather partner guides, versions, segments (e.g., X12 4010 vs 5010), and label specs.
Select approach: Direct, VAN, or hybrid; decide ownership (in-house vs managed service).
Map & validate: Build canonical mappings; enforce data quality (lengths, qualifiers, codes).
Connectivity setup: Exchange certificates, test AS2 endpoints or VAN mailboxes; set retries and MDN expectations.
Partner testing/certification: Run sample docs, negative tests, and corner cases until approved.
Cutover plan: Parallel run, rollback steps, and exception playbooks.
Operate & improve: Monitor SLAs, automate labeling/pack data, and add new partners and documents over time.
Speed: Near-real-time order and shipment flow; faster order-to-cash.
Accuracy: No manual rekeying; fewer chargebacks and deductions.
Compliance: Meet retailer/healthcare/automotive mandates and labeling rules.
Scalability: Add partners/documents without multiplying headcount.
Visibility: Track acknowledgments, shipment milestones, inventory positions.
Customer experience: On-time ASN + accurate labels = fewer receiving delays.

Fragmentation: Each partner’s guide differs; mappings proliferate.
Standards complexity: Versions, segments, qualifiers, and composite elements are exacting.
Testing cycles: Retailers often require certification, delaying go-live.
Exception handling: Bad reference data (SKUs, UOMs) breaks flows; you need reprocessing tools.
Skill gap: Mapping/translators and EDI protocol expertise can be scarce—managed services help.
Change management: Partner updates (e.g., label specs) must propagate cleanly.
EDI integration is the backbone of digital B2B trade. With the right blend of translator, transport, and integration layers, you get standardized, secure data exchange that accelerates operations and strengthens partner relationships. Start with your priority partners, pick a deployment model that fits your capacity, and build repeatable mappings and monitoring then scale confidently across your ecosystem.
