The Wayfair 850 Purchase Order, explained

What Wayfair expects in the 850

Wayfair trades on X12 4010 over API + AS2. Beyond the base standard, watch these:

How EDISQ maps it

The certified Wayfair 850 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against Wayfair's spec before transmission, and the sandbox replays Wayfair test scenarios until everything passes.

Common rejection reasons

Nearly all 850 rejections trace to reference data, not syntax: identifiers that don't match Wayfair's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before Wayfair ever sees the document.
