Code 50s are given when an invoice is missing an advertising allowance specified on the supplier agreement. Verify all information and terms on your purchase order prior to fulfilling the order. Your sales representative should have written correspondence for any “special” PO Deals. Suppliers should review POs before accepting them.
How to Prevent Valid Code 50s
Code 50s would only be triggered when there is an allowance listed on your PO and it is not listed on the invoice. Because these are only triggered when an allowance is given on your PO, Walmart does not allow disputes through the portal. You should review your allowances before shipping your PO.
Check with your EDI provider to make sure applicable allowances are being included on invoices.
Can it be Disputed?
Only through your buyer. Dispute with your buyer if you can prove that the allowance was actually given on the invoice.
The common scenario for invalid code 50s is that your Supplier Agreement states that an allowance is supposed to be given off-invoice, but your EDI provider is actually giving the allowance off-line-item. In this scenario, the correct dollar amount is being withheld from the invoice, just from the wrong place.
