The Opportunity

Problem

Small business owners are burdened by Stripe's high transaction fees that eat into profits and poor customer support that delays issue resolution.

Solution

FeeFox connects to your Stripe account via API and scans transactions for common fee errors like double-charges or incorrect categorizations. It automatically files refund claims with pre-vetted templates and tracks resolutions, saving you hours of manual support tickets. Get your money back faster without chasing Stripe support.

Target Audience

Small business owners processing online payments through Stripe

Differentiator

AI-powered fee anomaly detection with one-click refund filing, focused solely on fee recovery unlike general accounting tools.
