US Foods trades on X12 4010 over AS2. Beyond the base standard, watch these:
How EDISQ maps it
The certified US Foods 850 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against US Foods's spec before transmission, and the sandbox replays US Foods test scenarios until everything passes.
Common rejection reasons
Nearly all 850 rejections trace to reference data, not syntax: identifiers that don't match US Foods's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before US Foods ever sees the document.
