Walmart Code 11: Pricing overcharge (PO vs invoice).
Walmart Code 11 means your invoice price was higher than the cost on Walmart's purchase order, so Walmart paid the PO cost. It is disputable when an approved cost change was in effect for that order.
Why Walmart issues Code 11.
- A cost increase wasn't approved or effective yet
- The invoice used a new cost on an order placed at the old cost
- Unit-of-measure or pack-size mismatch
- A keying error on the invoice
Documents that win.
- Purchase order
- Invoice
- Approved cost change with its effective date
- Item records showing the correct cost
How to dispute it.
Locate Code 11 on your Walmart remittance and note the invoice and PO.
Collect every document listed above for that shipment.
Submit it in the Accounts Payable Dispute Portal (APDP) in Retail Link, with the documents attached.
If Walmart returns it for supplier action, respond within its 7-day window.
Reviews typically take about 60 to 75 days.
Why disputes on this code fail.
- The cost change took effect after the PO date
- There is no written approval of the new cost
PreventionInvoice at the PO cost and correct differences separately. Confirm effective dates before shipping at a new cost.
Walmart generally reviews accounts payable deduction disputes up to two years after the deduction. Dispute as early as possible: the oldest claims expire first.
