What Is the EDI 810?
The EDI 810 Invoice replaces the paper invoice in B2B transactions. It's sent by the supplier to the buyer after shipment to request payment. The 810 must match the original purchase order (850) and the advance ship notice (856) for three-way matching - a critical requirement for timely payment.
Key Data Elements
Critical elements in an EDI 810 include:
- BIG segment - Invoice number, date, and reference to the original PO number.
- IT1 segments - Invoiced line items with quantities, prices, and product identifiers.
- TDS segment - Total invoice amount including taxes and allowances.
- SAC segments - Service, promotion, and allowance charges.
- ISS segment - Invoice shipment summary with weight and quantity totals.
Three-Way Matching
Retailers perform three-way matching between the 850 (PO), 856 (ASN), and 810 (Invoice). Discrepancies in quantities, prices, or item identifiers result in payment holds or chargebacks. Automated validation before sending your 810 prevents most matching failures.
