Common Audit Types at CVS Health: What Suppliers Need to Know

Supplying CVS Health means operating under a structured set of audit programs. Like any major retailer, CVS uses a combination of supply chain performance audits, billing reviews, and quality system evaluations to hold suppliers financially accountable when standards are not met. Deductions come straight off your remittance, and missed dispute windows mean the money stays gone.

This article walks through the major audit types every CVS supplier should understand. For the complete and most current requirements, visit www.cvssuppliers.com.

What Are the Main Audit Types at CVS Health?

CVS runs several distinct audit programs. Each one targets a different area of supplier performance and carries its own penalty structure.

What Is a Fill Rate Audit and How Does It Work?

The fill rate audit measures whether you delivered the full quantity ordered on every line of a purchase order. CVS evaluates fill rate at the individual PO line level, not just the overall PO total.

Every line must hit a fill rate of 98% or higher. Here is the part that surprises many suppliers: even if your overall PO fill rate is 98% or above, a charge is still triggered if any single line falls below that threshold.

Fill rate is measured against the original PO content at the time the PO was created. Quantity adjustments made after PO creation are not recognized in the compliance system.

Key fill rate facts:

• POs are evaluated 10 calendar days from the first receipt date

• Original PO content must be received within a 5-day receipt window, which is the first receipt date plus the following 4 business days

• Penalty is 5% of the cost of the merchandise not delivered within the receipt window

• Charges for individual lines are totaled and processed as a single charge for the entire PO

This is similar in structure to Walmart's OTIF program, where both on-time and in-full performance are tracked at the line level and rolled up into a single performance score.

What Is an On-Time Delivery Audit and How Is It Calculated?

The on-time delivery audit measures whether your merchandise arrived within an acceptable window around the ship-to-arrive date on the original PO. CVS measures compliance against the STA date assigned at the time of PO creation. Updated STA dates are not applicable.

Requirements vary depending on your freight terms and shipping mode.

After individual PO assessment, CVS groups POs together based on their first common receipt date and evaluates weekly performance as a group. If your overall weekly on-time rate is 90% or higher, charges for that week are waived entirely. Falling below 90% triggers charges at 5% of the noncompliant merchandise cost.

DC holiday closure dates are not counted as business days. It is the supplier's responsibility to notify the demand planner if a holiday closure will affect delivery compliance.

What Is an ASN Audit and What Does It Cost?

An Advance Ship Notice audit measures whether your EDI 856 document was sent to CVS accurately and on time. Every warehouse shipment must be accompanied by an ASN received no later than one calendar day before the goods arrive at the distribution center.

CVS breaks ASN noncompliance into four categories with different penalty amounts.

A single ASN containing five POs with rejections generates $500 in charges from one transmission. A single PO can also incur multiple ASN charges if both a late and inaccurate violation apply.

The business-critical data elements your ASN must include are the BOL number, valid warehouse code, valid vendor number, SSCC bar codes, CVS SKU numbers, and case pack details. Missing any one of these triggers a missing ASN charge regardless of whether the document was sent on time.

This mirrors what suppliers face at Nordstrom, where a missing ASN on any shipment carries a $150 per incident offset, and at Walmart, where ASN accuracy directly affects your OTIF score and inventory positioning at the DC.

What Is an Appointment Integrity Audit?

The appointment integrity audit tracks your carrier's ability to honor scheduled delivery appointments at CVS distribution centers. If you ship prepaid, you are responsible for your carrier's performance under this program.

Three types of violations trigger charges, and penalties compound quickly.

Charges are assessed monthly, and a single appointment can generate multiple violations across multiple months. Traffic delays, mechanical breakdowns, and capacity issues are explicitly not grounds for reversal under CVS policy.

Unlike other programs, appointment integrity disputes are handled by email to the Supply Chain Performance team, not through the Traverse portal, and the dispute window is 45 calendar days from the payment remittance date.

What Is a Post Audit at CVS?

The post audit is CVS's backward-looking review of invoices already paid. CVS reserves the right to review all invoices paid in the current year plus two prior years. If discrepancies are found, the amount is deducted from your next remittance.

Duplicate invoice payments fall outside the two-year window entirely and can be flagged and deducted at any time with no expiration date.

Post audits commonly catch:

• Billing errors and pricing discrepancies

• Allowance calculation mistakes

• Duplicate payments

• Overpayments resulting from invoice errors

Suppliers have 60 days from the check date to dispute any deduction. After that window closes, the chargeback is considered valid regardless of accuracy. If you are not reconciling remittances within 60 days regularly, you are agreeing to every deduction by default.

This is consistent with how Walmart and Nordstrom run their accounts payable recovery programs, typically through third-party audit firms that review historical payment data for the same purpose.

What Are Packing List and Bill of Lading Audits?

CVS distribution centers review every inbound shipment for accurate and complete shipping documentation. These audits happen at the DC level, and violations are flagged per appointment.

If both documents are noncompliant on the same PO, that single PO can generate $200 in charges. The maximum combined charge per supplier per appointment is capped at $200 per document type.

The important distinction here, compared to other audit types, is that CVS does not accept disputes for packing list or BOL charges. Once a violation is flagged, it stands. The only path to avoiding these charges is prevention: working with your carriers to ensure every load ships with complete and accurate documentation.

What Is the Small Parcel Audit?

The small parcel audit enforces CVS's case limit for ground shipments into the distribution network. The program exists because small parcel ground deliveries cost more to process and take longer to receive than standard freight, which delays product availability at stores.

The limit is 15 cases per PO for both collect and prepaid freight terms. Cases consolidated into a master shipping carton are counted individually against the limit, not as a single unit.

The charge is $5 per case over the 15-case limit, up to a maximum of $150 per shipment.

This applies to all front-store small parcel ground deliveries. Pharmacy and direct-to-store delivery are excluded.

What Is a Quality System Audit at CVS?

For suppliers of CVS store brand products, there is a separate audit layer entirely: the Quality Audit Program, managed in partnership with UL, a third-party auditing firm. The type of audit required depends on whether your product is FDA-regulated.

New suppliers must complete a successful audit no later than 60 days before their products are scheduled to arrive at a CVS distribution center. A supplier that fails the audit at an unacceptable risk level is rejected as a provider and must remediate before being reconsidered.

Existing suppliers face annual audits. Corrective action plans for any non-conformances must be submitted within 30 days of the audit end date and fully approved within 45 days.

Key quality audit penalties:

• Late CAPA submission: $1,000 per late submission

• Late scheduling and completion of audit due to the supplier: $250 per month plus expedited audit fees

• Failure to disclose a contractor or change in supplier site: expedited audit expense plus potential termination

This mirrors the vendor compliance and social responsibility audit programs at large retailers like Walmart and Target, where the emphasis is on continuous improvement and consistent quality performance. A supplier that repeatedly fails audits risks losing the CVS business relationship entirely.

How Do You Dispute CVS Audit Charges?

Dispute processes vary by program, and using the wrong channel or missing the deadline results in automatic denial.

CVS does not accept OTIF or ASN disputes by email. The Traverse portal is the only accepted channel, and the dispute submission feature is disabled automatically after the deadline passes.

What Does This Mean for Your Business?

The audit landscape at CVS closely parallels what suppliers face at Walmart and Nordstrom, with CVS-specific portals, timelines, and contact channels layered on top. The common thread across all three retailers is the same: the burden of proof and the burden of timeliness fall entirely on the supplier.

Clean EDI, accurate shipping documents, on-time deliveries, complete orders, and a reconciliation process that catches issues within the dispute windows are the basics. Without those habits in place, deductions accumulate, and debit balances grow faster than most suppliers realize.

If you are not regularly logging into the CVS AP Vendor Portal, reviewing your remittances line by line, and submitting disputes through the correct channels within the required timeframes, you are leaving money on the table every single month.
