Subway
EDI Integration
& Compliance
Since 1965, Subway has grown from a single sandwich shop in Milford, Connecticut into a global quick-service powerhouse with one of the most demanding vendor routing guides in food service. Their EDI 850 purchase orders arrive with razor-thin fulfillment windows, while EDI 810 invoices must mirror exact line-item pricing or trigger immediate deductions. Manual data entry, missed AS2 transmissions, or a single misaligned segment can cascade into chargebacks that erode your margin overnight. Cogential IT's fully managed Cloud EDI Platform eliminates that risk entirely—we handle every protocol, every mapping, and every validation so your team never touches a raw EDI file again.
-
Zero-Chargeback Guarantee on Subway TransactionsOur proprietary validation engine cross-checks every 850, 810, and 875 against Subway's exact business rules before transmission. If a chargeback still occurs due to our error, we cover the penalty—no fine print, no exceptions.
-
AS2 & SFTP Handled NativelySubway requires both AS2 and SFTP connectivity depending on the document type. Cogential IT manages certificates, retries, and MDNs automatically, so you never miss a transmission window or fail an audit.
-
Pre-Mapped 875 Grocery Purchase OrdersThe 875 transaction set carries unique segment requirements for Subway's distribution network. We pre-configure every loop, qualifier, and reference designator, so your first test file passes with zero back-and-forth.
-
Seamless ERP Integration Without IT OverheadWhether you run SAP, NetSuite, or a legacy system, our cloud connectors translate Subway's EDI into clean, actionable data inside your existing workflows. No middleware to maintain, no internal EDI team required.
Where does Subway EDI compliance usually get stuck?
Most compliance issues arise when manual processes mismatch Subway’s automated validation rules and timing requirements.
Inconsistent invoice totals against original purchase order data frequently lead to automatic payment holds and settlement delays.
Incorrect AS2 encryption certificates or intermittent SFTP transfers cause retransmission failures and missed compliance windows.
