Why EDI projects feel ancient

Three reasons EDI in 2025 still costs $50k a year per trading partner.

EDI is the rails of B2B commerce, and it still runs like it's 1997. Here's why the modern EDI stack hasn't materialized for most companies.

01 - VAN fees

Per-character pricing for transmission you don't control

Value-Added Networks charge per kilo-character transmitted, marking up bandwidth that costs them effectively zero. A typical mid-market shipper pays $30k–$80k/year in VAN fees alone.

COST
02 - Trading-partner onboarding

Every new partner is a 6-week project

Each retailer publishes their own EDI implementation guide, 200 pages of segment requirements, qualifier maps, and version quirks. Onboarding takes weeks of testing per partner.

SETUP
03 - No real-time visibility

When a 940 fails, you find out from a phone call

Most EDI tools log transmissions but don't surface failures in operational tools. A failed 855 (PO acknowledgement) means the customer waits, and your CSR finds out from email when the customer gets impatient.

PLATFORM

Six products. One Platform.
Replace many legacy vendors.

Every tool Stacksync replaces is one fewer vendor, one fewer bill, one fewer integration to maintain.

Can we eliminate our VAN entirely?

For modern partners (most major retailers, all 3PLs), yes, direct AS2 or HTTPS API connections work fine. For partners who only accept VAN-routed traffic, Stacksync can connect via your existing VAN account or our shared one, but you only pay actual transmission cost, not bundled SKUs.

How quickly can we onboard a new trading partner?

Days, not weeks. Stacksync ships partner profiles for the top 200 retailers (Walmart, Target, Costco, Home Depot, etc.), pre-validated implementation guides, certified maps, and AS2 endpoints. Custom partners take 1–2 days.

What about acknowledgements and retries?

Stacksync handles 997 functional acks, MDN receipts (AS2), and SLA-driven retries automatically. Every document is durable and audit-logged from creation to delivery confirmation.

How do we monitor EDI in real time?

Every EDI document is a first-class object in Stacksync, query its status from the UI, dashboards, or your OMS. Failed transmissions trigger Slack/email/PagerDuty alerts before customers notice.
