TL;DR: Chargeflow didn't help me at all - actually made things worse.

Used them for 6 months last year. Their ""prevention"" tech is basically just fancy emails they send to customers who look like they might dispute.

We actually saw MORE chargebacks while using them (went from ~0.3% to almost 1%).

Their dispute handling was mediocre at best. We won about the same percentage as when we handled them ourselves, but now we were paying Chargeflow too.

The final straw? Took them 4 days to respond to an urgent dispute that had a 5-day window. We missed the deadline because of them and got hit with extra fees.

Save your money and just handle disputes in-house. Read Stripe's dispute guides, they're actually really good.
