AT&T EDI is the standardized electronic exchange of procurement, acknowledgment, shipping, and invoicing documents between AT&T and its supplier network. Built on X12 architecture, it automates order-to-cash workflows, enforces strict telecommunications-sector compliance, and synchronizes transactional data directly with ERP systems, eliminating manual entry while ensuring every shipment and invoice meets AT&T's exact specifications.
Every purchase order acknowledgment and invoice validated against AT&T's strict X12 mapping requirements before transmission.
Purchase orders, ship notices, and invoices sync directly into your ERP without manual re-entry or mismatched line items.
Stable AS2 and VAN connections keep every AT&T document exchange encrypted, acknowledged, and continuously monitored.
One misread segment. One late 855. That is all it takes for a supplier relationship with AT&T Inc. to turn expensive. The Dallas, Texas-headquartered telecommunications and electronics giant — whose modern corporate entity was chartered in 1983 and whose networks now underpin communications for millions of businesses — holds its vendors to a routing guide where every 850 purchase order demands a rapid 855 acknowledgement, every 856 ASN must carry GS1-128 barcode data, and every 810 invoice is reconciled against the original PO to the penny. Cogential IT absorbs that complexity for you: a fully managed Cloud EDI Platform, delivered as white-glove Managed EDI Services, with pre-configured segment mapping, dual AS2/VAN connectivity, and a real-time Validation Engine that catches errors before AT&T ever sees them — all backed by our Zero-Chargeback Guarantee.

Most compliance issues happen when daily business operations and AT&T EDI mapping are handled as separate workflows.
Acknowledgments missing accurate line-item status or timing codes fail AT&T validation and delay order confirmation downstream.
Carton counts, ship dates, or item identifiers mismatching physical shipments trigger chargebacks and receiving delays.
Invoices referencing unacknowledged quantities or incorrect pricing against original purchase orders face rejection and payment holds.
We combine telecom-sector mapping expertise, prebuilt ERP connectors, and round-the-clock monitoring so your AT&T transactions never stall, reject, or fall out of compliance.
Our engineers understand AT&T's supplier requirements deeply, building precise maps that pass validation on the very first submission attempt.
Connect AT&T EDI directly into Epicor, SAP, Infor, Oracle, Dynamics 365, SYSPRO, JD Edwards, or Plex without custom development.
Barcode labels and packing slips are generated from the exact same data as your ASN, eliminating costly physical-to-digital mismatches.
Every AT&T document exchange is monitored continuously, with instant alerts and corrective action taken before compliance failures escalate.

Before a single byte reaches AT&T's gateway, Cogential IT's proprietary Validation Engine has already stress-tested your document against their routing guide. It cross-references every 856 ASN line against the originating 850 — quantities, units of measure, ship-to nodes, and date qualifiers — verifies GS1-128 barcode structures down to the application identifier, and flags 810 invoice price drift before it becomes a deduction on your remittance. Errors surface in plain English with the exact segment and element identified, so your team resolves issues in minutes instead of discovering them in a compliance letter. The outcome: 99.9% data accuracy and chargebacks that simply never materialize.
