Each payment, email and check-in is sealed the moment it happens.

02Who it’s for

Any business that can show the customer got it.

A chargeback says “I didn’t buy this” or “I got nothing”. Your records say otherwise: the payment, the confirmation, and the moment the customer showed up or used what they paid for.

A new dispute shows up and walks through evidence, score and statement in front of you.

The seal on every case

Did they buy it, did they get it, did they use it: what is proven, at a glance.

04What the bank gets

A letter the bank can check, line by line.

Most responses are a screenshot of an order and a paragraph of protest. Ours is a statement where every sentence points at a record sealed before the dispute existed. Anything that arrived later is left out, so nothing looks staged.

09Questions

Questions people ask first

What kinds of business is it for?

Any business that takes card payments with Stripe and can show the customer got what they paid for: events and tickets, appointments and services, gyms and memberships, rentals, short stays, courses. Hingemark uses your industry’s words in every response.

What if we never recorded a check-in?

We still respond with the payment and the confirmation email, and tell you plainly that the case is weaker. If it isn’t worth fighting, we suggest a refund before a dispute fee lands on top.

Do you send anything without me?

No. Every response waits for a person on your team to read it and confirm the records are accurate. One colleague can approve and another can send.

Will this guarantee I win?

No one can. The bank decides. We show an evidence strength for every case and, once your cases close, your real win rate by reason.

What happens to my customers’ personal data?

It is encrypted per customer and deleted on a schedule: names after 30 days, closed cases after 180. A customer can ask for their data or its deletion through your team page.

My booking or ticketing tool isn’t listed.

Most tools can still connect: through Zapier or Make, a webhook, an order lookup your developer adds in an afternoon, or a CSV. The Setup page walks you through each, step by step.

Your next dispute is already on its way.

Create an account and connect Stripe in a few minutes. Nothing to pay until you win.
