What Is EDI 810?
The EDI 810 is an electronic invoice document that a seller, such as a manufacturer, distributor or supplier, sends to a buyer to request payment for goods shipped or services rendered. This invoice transaction replaces manual billing methods with a structured, machine-readable format that trading partners can process automatically.
The 810 transaction set follows the ANSI X12 standard maintained by the Accredited Standards Committee (ASC X12). The X12 810 format defines the exact syntax, segment order and data elements required for a compliant electronic invoice. Outside North America, the EDIFACT INVOIC message serves a similar function under international EDI document standards.
Unlike other specialized EDI invoicing documents such as the EDI 210 (freight invoice), EDI 880 (grocery products invoice) or EDI 894, the EDI 810 is a general-purpose invoice that works across industries : retail, manufacturing, distribution, automotive and healthcare. This versatility makes the 810 document the most widely used electronic billing transaction in the supply chain.
EDI 810 Invoice Components
The electronic invoice contains several mandatory data elements that mirror a traditional paper invoice. Understanding each component ensures your EDI integration captures all the information your accounts payable process requires.
EDI 810 Purchase Order References
The BIG segment opens every 810 transaction with the invoice date, invoice number and the original purchase order number. This purchase order reference is critical : it allows the buyer's system to link the electronic invoice back to the corresponding EDI 850 automatically. When multiple purchase orders appear on a single invoice, the REF segment carries additional reference identifiers such as bill of lading numbers or pro numbers.
EDI 810 Line Item Details
The IT1 segment contains the core billing data for each product or service invoiced. Line item number, quantity invoiced, unit of measure, unit price and product identification codes (UPC, vendor part number, buyer item number) are all structured within this segment. Subline details in the SLN segment break items down further when pack-level or component-level billing is required.
EDI 810 Payment Terms and Totals
The ITD segment specifies payment terms : net days, discount percentages and discount due dates. The TDS segment carries the total invoice amount. These fields feed directly into the buyer's accounts payable system, enabling automatic payment scheduling and cash flow forecasting without manual data entry.
EDI 810 Shipping and Tax Data
Shipping details, carrier identification and freight charges appear in the CAD segment. Tax amounts and tax codes are captured in dedicated segments when applicable. This data allows buyers to validate that the billed shipping charges and taxes align with the original order terms.
EDI 810 in the Order-to-Cash Workflow
The 810 invoice transaction does not operate in isolation. It is one step in the order-to-cash cycle, a sequence of EDI transaction sets that automate the full procurement and payment lifecycle.
The cycle begins when a buyer sends an EDI 850 purchase order to the seller. The seller responds with an EDI 855 (Purchase Order Acknowledgment) to confirm or modify the order. Before shipping, the seller transmits an EDI 856 (Advance Ship Notice) describing the shipment contents, packaging and tracking details. Once goods ship, the seller issues the EDI 810 invoice to request payment.
Upon receiving the 810 document, the buyer's system sends an EDI 997 (Functional Acknowledgment) to confirm receipt. If errors are detected, an EDI 864 (Text Message) may flag business violations in the invoice. When payment is ready, the buyer transmits an EDI 820 (Payment Order/Remittance Advice) to communicate payment details and any adjustments.
This electronic workflow eliminates the delays, errors and manual reconciliation that plague paper-based invoicing. Each transaction references the same purchase order number, creating a traceable audit trail across the entire supply chain.

Benefits of EDI 810 Invoicing
Implementing the EDI 810 electronic invoice delivers measurable advantages for both sellers and buyers across the procure-to-pay process.
EDI 810 payment speed and accuracy
Electronic invoicing eliminates manual data entry from the billing cycle. The seller's system generates the 810 transaction set automatically from order and shipment data, and the buyer's ERP system imports the invoice without human intervention. This EDI automation accelerates reconciliation, reduces processing costs and allows sellers to recognize revenue faster.
EDI 810 three-way match reconciliation
The most powerful advantage of the 810 document is its role in the three-way match : the buyer's system automatically compares the EDI 850 purchase order, the EDI 856 advance ship notice and the EDI 810 invoice. When all three documents align on quantities, prices and item codes, payment is approved without manual review. Discrepancies are flagged immediately, preventing overpayments and reducing invoice disputes.
EDI 810 compliance and chargebacks
Many retailers and large buyers mandate EDI invoicing as a compliance requirement. Suppliers that fail to send accurate, timely 810 invoices risk chargebacks, deductions and damaged trading partner relationships. The structured X12 format ensures that every invoice meets the buyer's specifications, reducing rejection rates and protecting the seller's revenue.
EDI 810 X12 Format Specification
The EDI 810 follows the X12 standard published by ASC X12 under the EDI document standards framework. The most common version in use is 4010 VICS, though versions 5010 and later are also supported.
Transaction structure — segment sequence
The transaction structure begins with ISA/GS envelope headers, followed by the ST segment (identifying the 810 transaction set), BIG (invoice date, number and purchase order reference), CUR (currency code when applicable), REF (additional reference numbers), N1 loops (buyer, seller, ship-to and remit-to party identification), ITD (payment terms), IT1 loops (line item details with quantities, prices and product codes), TDS (total invoice amount), CAD (carrier details) and CTT (transaction totals). SE/GE/IEA trailers close the envelope.
The format supports single-order and multi-order invoices. Sellers can include product descriptions in PID segments and subline details in SLN segments for complex billing scenarios. Because the X12 810 allows optional and conditional segments, working with an experienced EDI provider ensures correct mapping to each trading partner's specific requirements.
Related EDI transactions like the EDI 846 (Inventory Inquiry/Advice) and EDI 214 (Shipment Status Message) often complement the 810 in broader supply chain visibility workflows.
Common EDI 810 Implementation Errors
Even established EDI programs encounter problems with the 810 invoice transaction. Recognizing these issues early prevents payment delays and compliance failures.
EDI 810 and purchase order mismatches
The most frequent error occurs when data on the 810 invoice does not match the original EDI 850 purchase order. Mismatched item quantities, incorrect unit prices or wrong product codes cause the buyer's three-way match to fail. The invoice is rejected, delaying payment and creating manual rework. Implementing validation rules that cross-check 810 data against the 850 before transmission eliminates most rejections.
EDI 810 duplicate invoice issues
Sending the same 810 document twice, often caused by system retransmission errors, creates duplicate entries in the buyer's accounts payable system. Buyers may process and pay both invoices, leading to overpayment disputes. Unique invoice numbers in the BIG segment and deduplication logic in the receiving system prevent this problem.
Rejected EDI 810 transactions
Buyers define strict EDI specifications for the 810 format : required segments, acceptable qualifier codes and data element lengths. If a seller's invoice deviates from these specs, the transaction is rejected outright. Sellers should test all 810 configurations thoroughly during onboarding and monitor EDI 997 acknowledgments to catch rejections before they affect cash flow.
