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 get technically ready in days, not weeks 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.
