EDI 850: 850 purchase order guide

The 850 is the inbound purchase order that starts most supplier EDI workflows.

What the 850 is

An 850 tells a supplier what was ordered, where it ships, and which item identifiers matter.

PO number
Buyer location
Line items
Delivery dates

Plain-English Integration Visualizer

Simple example: a purchase order becomes a QuickBooks order draft

A retailer sends a purchase order, or your team uploads the file. SignalEDI checks it against the saved partner setup and prepares a QuickBooks-friendly draft.

1. File arrives

A buyer sends an 850 purchase order, or your team uploads the file you already have.

2. Signal matches it

Signal checks the saved partner and message setup. You do not choose EDI versus API at upload time.

3. Fields are checked

Names, item codes, quantities, dates, and required partner fields are reviewed before the file moves.

4. QuickBooks gets a draft

A clean order draft is prepared, and Live Activity shows whether it is checked, routed, or needs attention.

If something is wrong

Fix Issues explains the blocker in plain English, asks for approval, and only then retries or reprocesses.
