The Problem

If you’re a business who’s dealt with chargebacks, you’ve probably felt this:

🧹 You did everything right and still lost the money

“We shipped the product, supported the customer, submitted everything we had
 and still lost.”

The worst of all is, you don’t even know why you lost. It starts to feel like chargebacks are unwinnable, no matter what you do.

  • You didn’t know what to submit in the first place, since the guidelines weren’t clear
  • The loss reason from the bank is vague and unhelpful
  • And now Stripe’s adding a $15 fee every time you lose, making it even worse

🕒 It takes too much time

“It’s not worth an hour just to lose $50.”

  • Writing a response takes 30–60 minutes.
  • Gathering the evidence is a headache. It’s spread across Stripe, Shopify, email, shipping tools, and more.
  • Each case is a little different, so you can’t just copy-paste your last one.
