Chargeback Evidence Builder & Dispute AI
A SaaS platform that integrates with payment processors and email/project tools to proactively build a timeline of client approvals and change requests. When a chargeback hits, it generates a reason-code-specific evidence packet and rebuttal narrative.
Why this matters
You run a service business and a client fires you mid-project, then files a chargeback claiming they 'accidentally paid' or 'don't recognize the charge.' Your payment processor demands you submit evidence, but you're left manually digging through months of email threads, approval notes, and change requests to prove the client knowingly engaged your services. The processor's portal is a black box, and you have no structured way to link the client's signed approval to the transaction. You face losing the disputed amount plus hundreds in arbitration fees, with no clear guidance on whether fighting is worth the risk.
- · Built for Freelancers, digital agencies, and small service businesses processing $10k+ monthly via card payments who are vulnerable to client disputes..
- · Most likely monetization: SaaS subscription with tiered plans based on transaction volume.

- Onboard 3 pilot users from the waitlist to test the manual evidence compilation flow
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Reason 1 — Users only need this when a dispute happens, making it hard to retain subscribers during dry spells; the product feels like insurance that you hope to never use.
- 2Reason 2 — Building reliable email entity matching (linking an email address to a client and transaction) is technically complex and error-prone with unstructured data.
- 3Reason 3 — Payment processors like Stripe and Razorpay may improve their own native dispute resolution tools, making a standalone third-party tool redundant.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Multiple commenters emphasized the need to compile specific evidence like acceptance emails and change request threads to counter 'unauthorized charge' claims. Users noted that banks may not connect the dots between payment and email communications, requiring the merchant to explicitly spell out the link. The financial stakes are high, with mentions of losing the original amount plus $600 in fees, indicating strong willingness to pay for tools that de-risk this process.
