Everything compliant EDI needs.
AI-driven compliance, real-time validation, and shipping labels generated straight from your documents — the automation that turns EDI from a cost center into a competitive edge.
Stay compliant with every partner,

- 02 Control numbers, qualifiers, and mandatory segments validated to spec
- 03 Onboard a new trading partner in days, not months
- ST / SE control numbers match

- PO1 line items within spec
- Mandatory DTM/002 date qualifier
- REF*IA qualifier mapped automatically AI auto-fix
AI reads each partner's guideline and maps your data to spec — no manual EDI mapping.

FAQ
Frequently asked questions
How many EDI trading partners does Stacksync support?
Over 10,000 trading partners across retail, distribution, manufacturing, healthcare, and logistics. Each partner profile includes their preferred EDI channel (AS2, VAN, FTP/SFTP, API), supported transaction codes, and partner-specific implementation guidelines. The full directory is on this page. New trading partners are added on customer request, typical lead time from request to production-ready partner profile is 2 to 4 weeks.
Which EDI standards do you support?
Stacksync supports X12 (the dominant standard in North America) and EDIFACT (the dominant standard in Europe and global shipping). Within X12, the full set of common transactions is supported: 850 Purchase Order, 855 PO Acknowledgement, 856 ASN, 810 Invoice, 940 Warehouse Shipping Order, 945 Warehouse Shipping Advice, 997 Functional Acknowledgement, and dozens more. EDIFACT support includes ORDERS, ORDRSP, DESADV, INVOIC, and others.
Can I onboard a partner not in your catalogue?
Yes. Stacksync onboards new trading partners on customer request. The team handles partner outreach, channel certification (AS2, VAN, FTP), transaction-set mapping per the partner's implementation guide, and end-to-end testing. Typical timeline from kickoff to production-ready partner connection is 2 to 4 weeks. Custom transaction sets and proprietary partner formats are also supported.
How do you handle channel-specific guidelines?
Every partner has their own implementation guide, qualifier values, segment usage, mandatory vs optional elements, envelope conventions. Stacksync maintains a channel-level guideline for each partner in the directory, validates outbound transactions against the guideline before send, and surfaces guideline updates from the partner in the dashboard. Common guidelines (Walmart 850, Target 856, Amazon 940) are pre-built; custom guidelines are configured per partner during onboarding.
Is EDI monitoring real-time?
Yes. The Stacksync EDI dashboard shows every outbound and inbound transaction in real time: status, partner, channel, document type, payload size, validation result. Failed transactions surface immediately with the root cause (validation error, channel timeout, partner-side rejection). The dead-letter queue captures every failure for replay. SLA-grade monitoring alerts route to Slack, PagerDuty, email, or webhooks.
Can EDI data sync into my ERP or warehouse automatically?
Yes, that is the most common Stacksync EDI pattern. Inbound EDI documents (850 POs, 855 acks, 856 ASNs, 810 invoices) map directly into NetSuite, SAP, Workday, Dynamics, or your data warehouse. The Stacksync EDI engine handles the EDI-to-business-record translation, then the sync engine writes to the destination system using the same connectors used for non-EDI sync. End-to-end latency from partner-sent EDI to ERP record is typically under 30 seconds.
