Walmart Chargeback Code 11: Price difference between PO and invoice
Extracted from source — pending expert reviewLast verified: 2026-07-09
What this deduction means
A Code 11 is assessed when the item cost on the invoice does not match the cost on the purchase order. Walmart deducts the difference between the invoiced cost and the PO cost.
Typical penalty: Equal to the per-unit cost difference between the invoice and the PO
Common causes
- Invoice cost higher than the cost stated on the PO
- A price change not reflected on the PO before invoicing
- The wrong cost tier billed
How to prevent Walmart code 11
- Bill the exact cost stated on the PO
- Reconcile invoice cost against the 850 (PO) before sending the 810
- Confirm any price change updates the PO first
