EDI 810 Invoice Builder

What an 810 Invoice Is

The X12 810 is the electronic equivalent of a paper invoice. Retailers, distributors, and manufacturers require it from their vendors so that accounts payable can match invoices against purchase orders (850s) and receipts (856s) automatically. A valid 810 carries the invoice number, dates, remit-to and bill-to addresses, line items with quantity, unit, and unit price, any freight or tax charges, and a grand total — all wrapped in the standard ISA/GS/ST envelope that identifies sender, receiver, and control numbers.

Who This Tool Is For

Larger suppliers run EDI through a VAN or a translator built into their ERP. Any vendor without that infrastructure — a single-product maker, a farm, a small distributor, or anyone who has just received a “submit your invoices as EDI 810” letter from a buyer — can use this tool to produce the required file without paying for a full platform or an expensive per-document service. Enter invoice details once, save the trading-partner profile, and every future invoice is a short form and a download. Import from QuickBooks (IIF or Online CSV) skips retyping line items when the accounting system already has them.

How This Tool Generates a Valid 810

The tool composes a standard ANSI X12 4010 envelope: a fixed-length 106-character ISA, a GS functional group header with IN (invoice) identifier, and an ST transaction set containing a BIG (invoice header), N1/N3/N4 loops for remit-to and bill-to addresses, IT1 segments for each line item with a PID description, optional SAC segments for freight, tax, and discounts, a TDS grand total in implied-decimal cents, and a CTT line count. Control numbers auto-generate from the current timestamp; you can override them if your trading partner requires sequential numbering. The generated file parses cleanly through the EDI File Parser, which is useful for verifying the output before you submit.

What This Tool Isn't

This is a lightweight, draft-builder tool. It produces a syntactically valid 810 that most trading partners will accept with minor tweaks, but it doesn't handle partner-specific implementation guides (custom qualifier codes, optional segment requirements, 5010 variants, per-partner SAC code preferences). It also doesn't handle transmission — you still need a way to deliver the file (AS2, SFTP, VAN, email). If your buyer rejects an invoice for a spec reason, Ask James — I can adjust the output to match their guide.

EDI Integration with Your Systems

Most of the EDI integration work I do bridges X12 and whatever formats your systems produce and consume — modern APIs, database tables, spreadsheet exports, flat files, or legacy platform-native formats. Inbound direction: a partner's 850/856/997 lands in the exact shape your order entry, WMS, or AP system expects. Outbound direction: validator-clean 810/850/855/856/820 built from your systems' native data — handling partner-specific variations, acknowledgments, and exception workflows.

Need a Customized 856 ASN?

Advance Ship Notices (856s) can't be “lightweight.” Every retailer's ASN spec is different — pack-level vs. carton-level hierarchy with nested HL loops, SSCC-18 license plate numbers, partner-specific qualifier codes, and implementation guides that run 80+ pages. I build 856s to your trading partner's exact spec, tested against their validator, plus the 810 integration to match. For help with ASNs, full EDI onboarding with a new retailer, or automating the 810/856/997 loop between your ERP and the buyer, Ask James.
