What Causes an MDF/Co-op Claim Rejection?
Claim rejection is when a vendor denies a partner's MDF or co-op claim, so the spend isn't reimbursed. The most common causes are missing pre-approval, filing after the claim window, incomplete or non-compliant proof of performance, ineligible activities, or spend that doesn't match the approved activity plan.
Why it matters to IT channel partners. A rejected claim means the partner fronted real marketing cash and gets nothing back. Rejections are almost always preventable - they come from process gaps, not bad campaigns. Knowing each vendor's requirements, deadlines and proof rules up front is what keeps approved spend from turning into a write-off.
