CVS Code CVS-PRC: Pricing discrepancy chargeback (PO vs. invoice unit cost).
CVS Pricing Discrepancy chargebacks occur when the unit cost on your invoice is higher than the agreed cost on CVS's purchase order, resulting in an automatic debit memo with a W, X, or V suffix. Disputing requires verified buyer pricing agreements or cost acceptance confirmation.
Why CVS issues Code CVS-PRC.
- Approved cost increase was not updated in CVS's purchasing system prior to PO generation
- Case-cost vs. each-cost billing unit-of-measure mismatch on the EDI 810 invoice
- Promotional price reduction expired, but the supplier invoiced at the promotional rate
Documents that win.
- Approved CVS cost-change notification and buyer acceptance letter
- Original Purchase Order (EDI 850) and Vendor Invoice (EDI 810)
- ImageSilo debit memo backup showing 'Pricing Discrepancy'
