The Menards 850 Purchase Order, explained

What Menards expects in the 850

Menards trades on X12 4010 over AS2. Beyond the base standard, watch these:

How EDISQ maps it

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

Common rejection reasons

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