Retailer-compliant EDI. No middleware tax.
Connect to major retailers with native EDI. Automate POs, ASNs, invoices, acknowledgements, and GS1-128 shipping labels inside the same platform that runs your product, inventory, orders, and warehouse execution.

No third-party portal between your ERP and the retailer. No middleware contract. No rebuilt carton data.
Your ASN was supposed to be transmitted before the shipment landed. Retailer policy says: no ASN, automatic chargeback. The middleware portal your team relies on queued the ASN but couldn't push it — there was a format mismatch nobody spotted until Monday.
The truck arrived Friday afternoon. The chargeback arrived Monday morning. Six figures, in a year, across a handful of retailers, just from compliance edge cases.
The same week, a label printed without a valid SSCC because the carton data and the label print job were running in different systems on different cadences. Two cartons got rejected at the receiving dock. A separate retailer flagged an invoice mismatch on a PO with revised quantities the middleware hadn't picked up. Each one is a small failure. Together they add up to the line item finance keeps quietly absorbing every quarter.
Retailer EDI compliance isn't a nice-to-have. It's a margin issue. And middleware makes it harder, not easier.
Nordstrom, Macy's, Saks — every major retailer has published an EDI spec, and it is unforgiving. ASN must transmit before the truck arrives. Carton label must be GS1-128 compliant with a valid SSCC. Invoice must reference the PO exactly, in the exact format, or it gets rejected. Miss any of it and the chargeback is automatic.
Most apparel brands solve this by bolting a third-party EDI middleware layer on top of their ERP. The middleware works, mostly, but creates a new problem: every document is a hand-off. POs come into the portal and get re-keyed into orders. ASN data gets reconstructed from pick-and-pack by somebody connecting dots across three screens. Acknowledgements arrive in the middleware but nobody sees them until a rejection becomes a chargeback.
Uphance runs EDI natively inside the operational platform. POs ingest directly into order management. ASNs generate from warehouse activity in real time. GS1-128 labels print from the same carton data the ASN references.
POs, POAs, ASNs, invoices, acknowledgements exchanged automatically.
GS1-128 (UCC-128) labels and SSCC generation, tied to carton data and ASN.
Size/color matrices, prepacks, split shipments, multi-warehouse, native.
Formatting, timing, label rules per retailer. ASN before arrival. Partner-specific versions.
Functional acks and exceptions surface before they become chargebacks.
ANSI X12 (NA), UN/EDIFACT (global), GS1 EANCOM. Onboard US, UK, EU, AU without switching.
Twenty years ago, bolting an EDI middleware layer onto your ERP was a sensible architecture. EDI was a specialized protocol, retailers were a small slice of your business, and the cost of middleware was easier to swallow than building EDI natively.
The math has changed. Retailer compliance requirements have tightened. Chargebacks are larger and more automatic. Middleware contracts are a recurring tax. And the operational cost of every document being a hand-off between two systems has gotten harder to hide.
EDI belongs inside the operational system. Not next to it.
