How long do EDI providers keep your 850, 856 and 810 history?

Where your EDI history actually lives#

Your 850, 856 and 810 history usually lives in several places at once, and each copy has a different owner of the retention rules. Knowing which copy you control is the first step to knowing how long you can rely on it.

For many mid-size distributors, the only copies fully under their control are the ERP records and whatever their own translator or integration platform archives. Everything else can change or disappear when a contract, plan or trading relationship changes.

Why provider retention is not your archive#

EDI provider retention exists to support day-to-day operations, not your audit, dispute or analysis needs. Plans differ in how far back portal search reaches, and the history kept for raw files and for portal views may not be the same. The only reliable answer is the one written in your contract or confirmed by the provider in writing.

Switching providers is a common point of loss. When the contract ends, portal access usually ends with it, and the new provider starts with an empty archive. Retail compliance disputes, such as a chargeback for a late or inaccurate 856, can arrive long after the shipment, by which time the evidence may sit with a provider you no longer pay.

The rule: keep raw X12 plus the translated records#

Keep both the raw X12 files and the records your systems created from them, because each answers a different question. The raw interchange shows exactly what was sent or received, with its envelopes and control numbers. The translated record shows what your business did with it: the sales order, the pick, the shipment and the invoice.

Name and index files so a person can find them without the original system: trading partner, transaction set, control number, document number and date. An archive that only the old translator can read is not much better than no archive at all.

• 1Raw interchanges with ISA and GS envelopes intact, stored exactly as sent or received.
• 2Functional acknowledgments, 997 or 999, matched to the documents they acknowledge.
• 3AS2 MDN receipts or VAN delivery logs that prove transmission.
• 4Translated documents in a readable form such as CSV or JSON, with the map version used.
• 5The ERP records created from each document, linked by PO number, shipment ID and invoice number.
• 6Trading partner implementation guides, in the versions in force at the time.
• 7Chargeback notices, deduction backup and the resolution of each dispute.

How 850, 856 and 810 records connect#

The purchase order number ties the order, the shipment and the invoice together across transaction sets. In the 850 it sits in the BEG segment, the 856 references it at order level, typically in a PRF segment, and the 810 carries it in the BIG segment alongside the invoice number.

How to pull history before you switch or cancel#

Pull your full EDI history from the provider while you still have a paid account and a cooperative provider. Ask early, because bulk exports of raw files can require a support request rather than a button in the portal.

Then write the export obligation into the next contract. A clause requiring the provider to deliver all raw and translated history in a standard format at termination is far easier to agree at signing than to argue about at exit.

• 1Step 1: ask the provider in writing what it retains, for how long, in which formats, and what happens after termination.
• 2Step 2: request a bulk export of raw interchanges and acknowledgments for every trading partner and the full date range.
• 3Step 3: export translated documents and portal reports wherever the bulk export does not cover them.
• 4Step 4: reconcile counts by partner, transaction set and month against ERP orders, fulfillments and invoices.
• 5Step 5: store the archive in two locations you control, with an index and a hash of each file.
• 6Step 6: keep the maps and partner specifications so the files can be read later.

Illustrative: an industrial distributor changes EDI providers#

Illustrative: a fictional distributor of fluid power components sells to national retailers and to maintenance buyers at manufacturing plants. It runs NetSuite and a web EDI provider for its 850, 856 and 810 traffic, and decides to move to an integration platform it can manage itself.

Before cancelling, the VP of operations asks what the old provider keeps. Portal search reaches back only part of the relationship, and raw files need a support request. The team requests a full export, matches each 856 to its NetSuite item fulfillment and each 810 to its invoice, and stores the archive indexed by PO number.

Later, a retailer issues chargebacks for ASNs it says arrived after the shipments. The distributor produces the raw 856 files with their transmission records and the matching 997 acknowledgments, and the disputes are settled on evidence rather than argument.

Why EDI history matters beyond disputes#

A clean EDI archive records how orders, shipments and invoices actually flowed between companies, including the exceptions: short shipments, substitutions, late ASNs and deductions. Linked to ERP records and the notes that explain each resolution, that history supports operations analysis and, after rights review, can be considered for licensing to AI developers building supply chain and logistics tools.

Trading partner documents carry the partner's pricing and terms, so customer contracts and confidentiality obligations decide what can be used. The first conversation with SourceX covers only systems, trading partner counts and years of history, and any package that follows moves through the SourceX five-step transaction of Supply, Rights, Preparation, Approval and Delivery. Partner pricing and identities are reviewed in the Rights and Preparation steps, the distributor approves the final scope, and a SourceX Evidence Packet lists which trading partners' documents were included and on what basis.
