What EDI documents does REI require?

Most REI supplier programs center on order-to-cash X12 sets — typically 850 purchase orders, 855 acknowledgments, 856 advance ship notices, and 810 invoices. Additional sets vary by category; confirm against your REI Vendor Portal implementation guide.

How long does REI EDI onboarding take?

Industry averages land around 1–2 weeks, but timelines depend on test cycles, DC routing, and exception handling in REI Vendor Portal. SignalEDI helps your team prepare the technical work you control while the retailer controls certification approval.

Can SignalEDI help avoid retailer chargebacks?

SignalEDI validates ASN, PO reference, and invoice alignment before files leave your control — catching mismatches early reduces the chargeback exposure common on high-volume retail programs.

Supplier programs & chargeback risk

Chargeback exposure: High — late/missing ASNs, incorrect labels, and late routing instructions all trigger fines

Penalty amounts, fees, endpoints, and onboarding windows reflect each retailer's published routing guides and public sources and change frequently. Confirm current figures in the retailer's own vendor portal before relying on them.
