What GSA Advantage expects in the 855
GSA Advantage trades on X12 4010 over VAN. GSA Advantage's 855 follows the standard X12 layout — no partner-specific companion-guide quirks are curated for this document yet. The certified base map covers the standard requirements, and validation still runs against the 855 spec before anything transmits.
How EDISQ maps it
The certified GSA Advantage 855 map loads when you enable the partner — fields auto-map from NetSuite, QuickBooks, Dynamics, and 33 other systems, validation runs against GSA Advantage's spec before transmission, and the sandbox replays GSA Advantage test scenarios until everything passes.
Common rejection reasons
Nearly all 855 rejections trace to reference data, not syntax: identifiers that don't match GSA Advantage's cross-references, echoed fields dropped from the original PO, or timing that misses the program window. EDISQ flags each before GSA Advantage ever sees the document.
