EDI 810: The Invoice, Explained

EdiPeek · Updated June 2026 · 5 min read

The EDI 810 is the Invoice — the supplier's electronic bill for goods or services. It is the EDI counterpart of a paper invoice, and it usually arrives after the goods have shipped.

How the 810 connects to the order

An 810 almost always references the original 850 purchase order. The buyer's accounts-payable system performs a "three-way match": the purchase order (850), the receipt of goods (often from the 856 ship notice), and this invoice (810). If all three agree, the invoice is paid automatically.

Key segments in an 810

BIG — Beginning Segment for Invoice

Carries the invoice date and number, and references the PO. BIG*20240225*INV-3391*20240115*PO-99831 = invoice INV-3391 dated 2024-02-25, against PO-99831.

N1 — Parties

IT1 — Invoice Line Item

One per billed line. IT1*1*100*EA*12.50**UP*012345678905 mirrors the PO1 from the original order: 100 each at $12.50.

TDS — Total Monetary Summary

The invoice total, in cents. TDS*168750 means $1,687.50.
