CVS Code CVS-ALW: Allowance discrepancy / unapplied trade allowance.
CVS Allowance deductions represent trade, promotional, or contractual allowances that CVS's AP system expected to deduct from your payment. They carry W, X, or V invoice suffixes and are verified via ImageSilo backup documents. They are disputable if double-deducted or applied outside contract terms.
Why CVS issues Code CVS-ALW.
- Contractual trade allowance was omitted as a deduction line on the EDI 810 invoice
- Allowance was already netted into the invoice unit price, causing a duplicate deduction
- Promotional allowance applied to non-promotional POs
Documents that win.
- Signed CVS Vendor Agreement and promotional deal sheet
- Invoice showing the allowance was already applied off-invoice
- ImageSilo debit memo backup record
