CVS Health EDI Compliance Guide
EDI compliance for CVS Health suppliers across pharmacy and retail
Quick Answer
CVS Health requires EDI 850 (Purchase Order), EDI 855 (PO Acknowledgment), EDI 856 (Ship Notice (ASN)), EDI 810 (Invoice), EDI 997 (Functional Acknowledgment) from all suppliers. Non-compliance triggers chargebacks including late or missing ASN: $200-$400 per shipment.
CVS Health operates over 9,000 pharmacy and retail locations across the US, sourcing from suppliers in health and beauty, over-the-counter pharmaceuticals, general merchandise, and seasonal categories. CVS requires EDI compliance from all direct-import and domestic suppliers. Pharmaceutical suppliers face additional requirements including National Drug Code (NDC) identifiers and DEA compliance documentation. CVS uses the CVS Supplier Center for onboarding and performance management.
Required EDI Transactions
CVS Health requires suppliers to support the following EDI transaction types. Click any transaction to view our detailed guide with segment breakdowns and examples.
CVS Health-Specific Transaction Requirements
- EDI 810 (Invoice): Invoices match against the PO. Pricing or quantity discrepancies become deductions that take cycles to dispute.
- EDI 850 (Purchase Order): CVS transmits POs by distribution center with department-level detail. Order volumes swing hard around promotional resets, so automated intake matters.
- EDI 856 (Ship Notice (ASN)): ASNs must match GS1-128 carton labels and arrive ahead of freight. DC receiving scans against ASN contents.
Compliance Requirements
Here is what CVS Health expects from EDI-compliant suppliers:
- EDI 850 Purchase Order processing via CVS Supplier Center
- EDI 855 PO Acknowledgment with availability confirmation
- EDI 856 ASN with case-level detail before shipment arrival
- EDI 810 Invoice matching PO and pricing
- EDI 997 Functional Acknowledgment
- GS1 GTIN compliance for all products

How to Achieve CVS Health EDI Compliance
Getting compliant with CVS Health requires three things: an EDI platform that supports all required transaction types, automated validation that catches errors before they trigger chargebacks, and integration with your ERP so orders flow through without manual re-entry.
EDI transaction formats follow ASC X12 standards, and product identification uses GS1 GTIN and GS1-128 barcode specifications. Both are required by virtually every major US retailer.
OrderSync handles all three compliance layers. Our platform processes EDI transactions (850, 855, 856, 810, 997) alongside PDF, CSV, and email orders through a single pipeline. Automated validation checks every order against your product catalog, pricing rules, and CVS Health-specific compliance requirements before syncing to your ERP.

What is CVS EDI?
CVS EDI is the document exchange CVS Health requires from merchandise suppliers: CVS sends 850 purchase orders, and suppliers return 856 advance ship notices, 810 invoices, and 997 acknowledgments. Onboarding and requirements are managed through the CVS Suppliers portal.
How do I become an EDI-compliant CVS supplier?
Start at cvssuppliers.com. After your supplier agreement is in place, CVS provides EDI implementation guides and identifiers, then you test each document type before going live. An EDI platform that validates ASN and invoice data against the original PO keeps you out of the deduction cycle.
Do pharmacy products use the same CVS EDI flow?
Mostly no. Front-store merchandise trades directly between supplier and CVS. Pharmaceutical product generally flows through wholesale distributors, where DSCSA serialization requirements apply, and the distributor handles the EDI relationship with CVS.
