CVS Health requires full EDI compliance from all suppliers regardless of size — the mandate was extended to small suppliers in 2024. The core document set is the EDI 850 purchase order, 856 advance ship notice, 810 invoice, and 997 functional acknowledgment. Every shipment must carry GS1-128 carton labels that match an accurate, on-time 856 ASN, and performance chargebacks are managed in CVS's Traverse Portal under the Supply Chain Performance program. Low-volume vendors can use a web portal option instead of a full integration, and supplier onboarding runs through cvssuppliers.com.
CVS publishes flat-fee ASN penalties that are deducted from payment and summarized in a weekly compliance email:
Chargebacks appear in the Traverse Portal, where CVS's Supply Chain Performance program tracks each supplier's compliance. One deadline matters more than any other: compliance fines are not disputable after 45 days from the deduction date. Review the weekly compliance summary email as soon as it lands — a fine you spot in week seven is a fine you keep.
CVS requires a GS1-128 barcode label on every carton, tied to the 856 ASN. A common and expensive misunderstanding: pallet labels do not replace carton labels. Even fully palletized shipments need scannable GS1-128 labels on each carton, and the SSCC data in the ASN must match what receiving scans on the dock.
Pallets themselves are also specified: CVS requires 48" x 40" hardwood pallets — plastic and CHEP pallets are not accepted.
The 856 ASN must accurately reflect the contents of the shipment — correct item numbers, accurate quantities, and packaging details that match the physical cartons. Any discrepancy between the ASN and the actual shipment can trigger the $50 inaccurate-ASN charge per shipment, and a missing ASN costs $100 per PO. Submit the ASN before the shipment arrives so CVS receiving can process the delivery without exceptions.
CVS measures on-time performance against the Ship-to-Arrive (STA) date on the purchase order. A PO may arrive on the STA date or up to 4 business days before it — outside that window counts against your on-time, in-full performance. Build the STA window into your routing and carrier planning, not just your ASN timing.
For small and mid-sized suppliers, the CVS penalty schedule is a per-shipment tax on manual process. Automating the 850-to-856-to-810 flow removes the two most common causes of chargebacks: ASNs generated late from batch jobs, and ASN data typed by hand that no longer matches the cartons. With self-serve EDI onboarding, SMBs can stand up a validated CVS connection without an IT team — mapping, validation, and label-to-ASN consistency checks run in the platform. See the EDI transaction set reference for the documents involved, and the EDI onboarding guide for how self-serve setup works.
You incur flat-fee chargebacks: $100 per PO for a missing ASN, $75 per shipment for a late ASN, and $50 per shipment for an inaccurate ASN. Fines are deducted from payment, tracked in the Traverse Portal, and cannot be disputed more than 45 days after the deduction.
Yes. CVS extended its EDI mandate to small suppliers in 2024, so full compliance is required regardless of size. Low-volume vendors can use CVS's web portal option instead of a full integration, but the ASN, labeling, and timing requirements still apply.
In the Traverse Portal, under the Supply Chain Performance program. CVS also sends a weekly compliance summary email — treat it as your dispute clock, because fines are final 45 days after deduction.
Supplier onboarding runs through cvssuppliers.com on the CVS side. On your side, self-serve onboarding at SignalEDI lets you register and begin integrating your EDI workflows quickly — see the EDI onboarding guide for detailed steps or the Developer QuickStart.
Meeting CVS's EDI requirements comes down to three disciplines: an accurate 856 ASN sent before the shipment arrives, GS1-128 carton labels that match it, and a weekly habit of reviewing the Traverse compliance summary inside the 45-day dispute window. EDI automation built for SMBs makes all three routine.
