The issue
A dispute packet should make it easy to connect the withheld amount to the transaction and understand why the supplier believes the deduction is incorrect. The exact portal and required documents can vary by claim type.
Documents to gather
- Claim or invoice reference
- Short dispute narrative
- Invoice and purchase order
- Delivery or receiving evidence
- Relevant allowance or promotion agreement
Review checklist
- Use the same references shown in the remittance
- Explain the disagreement in plain language
- Attach only evidence that supports the specific claim
- Confirm the claim is routed to the current channel
- Save the confirmation number and submission screenshot
