The X12 810 is the electronic invoice a supplier issues against a purchase order. It carries the invoice number and date (BIG), the PO reference, line items with quantity, unit price, and unit of measure (IT1), allowances and charges (SAC), and the total amount due (TDS). Buyers require it so accounts payable can match invoices against purchase order and receipt data automatically, and a clean 810 is a precondition for on-time payment. The supplier or seller sends the 810 to the buyer (retailer, distributor, or manufacturer) after shipping the order, closing the loop opened by the EDI 850 purchase order.

When it fires: An order ships or a service is completed against a purchase order and the seller's ERP generates the invoice, usually at shipment confirmation.

Common 810 rejection causes
  • PO number mismatch: if BIG04 does not echo the buyer's 850 exactly, the invoice lands in a rejection queue and payment stalls.
  • TDS totals computed anywhere other than from the line data, or with rounding that differs from the buyer's standard, cause the AP system to hold or short-pay the invoice.
  • Stale party or location code tables in the N1 loop produce invalid ship-to deductions and misapplied cash receipts.
  • Invoiced quantities that conflict with the EDI 856 ASN, or unapproved SAC allowance and charge codes, drive short-pays and repeat deduction research.
