Learn moreDisputeProof — Win More Disputes, Recover More Revenue
Most disputes are lost because evidence is incomplete or misaligned with the reason code — not because the merchant was wrong. DisputeProof analyzes each case, recommends the specific evidence that wins under the relevant rule, runs a pre-submission audit, generates objective rebuttal drafts, and assembles a submission-ready response packet and combined evidence PDF.
Combined with hands-on support from your dedicated account manager, you get the best of both worlds: software efficiency and human expertise when it matters most.
A Payment Processor That Actually Knows You
With large self-serve processors, you are just an account number. When problems arise — chargebacks, holds, rate questions — you are on your own. FinMI is different. Every merchant gets a dedicated account manager who knows your business, your industry, and your goals.
Dedicated Manager
A real person assigned to your account — not a rotating support queue.
Chargeback Advocacy
When disputes happen, your manager helps you build the strongest possible case.
Always Reachable
Phone, email, and real-time support. No bots, no ticket systems.
