Retail Network
Trading PartnerWestRock EDI is the standardized electronic exchange of procurement, fulfillment, and billing documents between WestRock and its Paper & Packaging supply chain partners. It automates purchase order receipt, acknowledgment, shipment notification, and invoicing through X12-compliant mappings, AS2 or VAN transport, and validated data flows synchronized directly with your ERP environment.
Validate every purchase order acknowledgment and invoice against WestRock's X12 mapping specifications before transmission.
Synchronize shipment, pricing, and billing data directly into your ERP to eliminate manual re-entry errors.
Maintain stable AS2 and VAN connections with continuous monitoring, automated retries, and acknowledged receipts.
One malformed segment in an EDI 856 and a WestRock distribution center can hold your shipment — and freeze the invoice behind it. Born from the 2015 merger of RockTenn and MeadWestvaco and run from its Sandy Springs, Georgia headquarters, WestRock enforces a routing guide with zero patience for error: strict GS1-128 barcode labeling, branded packing slips on DSV orders, and precise AS2/VAN transmissions. Cogential IT absorbs that entire burden — EDI compliance is handled for you, segment by segment, so your team never touches a mapping rule and never eats a chargeback.
Most WestRock compliance failures occur when operational teams and EDI mapping work in disconnected silos.
Unmapped purchase order change requests create version conflicts between WestRock requirements and your live ERP orders.
Mismatched carton, label, and quantity data between physical shipments and ASNs triggers chargebacks and costly rejections.
Invoices that fail to match acknowledged orders and shipped quantities stall remittance and strain cash flow.
We combine certified X12 mapping expertise, prebuilt ERP connectors, and round-the-clock monitoring so WestRock suppliers stay compliant without adding internal EDI headcount.
Our engineers build WestRock-specific X12 maps that validate every segment and qualifier before documents ever reach their gateway.
Certified connectors for Epicor, SAP, Infor, Oracle, Dynamics, and SYSPRO push EDI data straight into your existing workflows.
Barcode labels, packing slips, and ship notices are generated from one synchronized data source, eliminating costly physical-to-digital mismatches.
Every AS2 session and VAN transmission is monitored continuously with automated retries, acknowledgments, and immediate proactive alert escalation.
Most suppliers go live within weeks through preconfigured maps, pretested connections, and structured WestRock certification testing support from day one.
Named integration specialists handle mapping changes, specification updates, and urgent troubleshooting so your operations team never flies blind.

WestRock's vendor requirements read like a legal contract: exact segment sequencing, mandatory qualifiers, tight date formats, and ship-to data that must reconcile perfectly across the 850, 855, 856, and 810. Cogential IT's proprietary Validation Engine interrogates every outbound document against their live routing guide before transmission — catching the missing DTM segment, the mismatched PO number, or the non-compliant barcode string while it's still fixable. Errors surface in plain English, not cryptic 997 jargon, so your team resolves issues in minutes. The result: documents that sail through WestRock's gateway the first time, backed by our Zero-Chargeback Guarantee.
