Win more disputes.
Pay a flat fee.

Connecting Stripe takes about two minutes and needs no developer: Flatfight imports your disputes and starts working with your Stripe data right away. Activity data (logins, usage, downloads) is optional and is what turns many weak cases into strong ones: connect PostHog in one click, paste a Teachable API key, paste a URL into Segment, RudderStack or Thinkific, or upload a CSV.

Stripe, through the Flatfight Stripe App. For activity: PostHog and Teachable (Flatfight looks up only the customer who disputes, read-only), Segment and RudderStack, and Thinkific. Anything else works through a CSV upload or the Activity API.

Fraudulent, subscription canceled, product not received, product unacceptable, duplicate, credit not processed and general disputes, plus inquiries, each with evidence matched to the reason. Network compliance disputes need a fee acknowledgement in Stripe, so Flatfight shows them but leaves the response to you.

Two ways to pay, neither a percentage. Pay per win: no monthly fee, and each won dispute costs $9, or $19 if it's $100 or more; lose one and you pay nothing. Or a flat monthly plan: Starter ($49, up to 15 disputes a month) or Scale ($99, up to 50), with nothing charged per win. Need more than 50 a month? Ask us for a custom plan. Every dispute gets its full response either way.

When Stripe marks a dispute as won and its response was prepared by Flatfight, whether we submitted it or you downloaded it and submitted it yourself. Disputes you answered without our response, Smart Disputes submissions and inquiries are never charged. Wins are added to one monthly invoice.

No. Connect Stripe and every open dispute gets its score, the evidence found and the full response, with no card. We ask for a card when you first submit a response.

Yes. The documents follow Stripe's published evidence guidelines (docs.stripe.com/disputes/best-practices): a summary with a timeline comes first, each document opens with what it proves, text is 12-point or larger on Letter or A4 pages, key details are in bold rather than colour, policies show only the relevant section, there are no links (banks don't follow them), and each evidence type is one file. Every package stays within Stripe's limits of 4.5 MB, 19 pages (Mastercard's maximum, applied to every card) and 150,000 characters of text. You can read a full sample before signing up.

Yes. The Flatfight Stripe App shows the case score, the deadline and what would make it stronger on every disputed payment, and lists your open disputes in the app drawer. One click opens the dispute in Flatfight to review and submit.

Only if you turn on automatic cancellation in Settings; it's off by default. Then, when a chargeback arrives on a subscription payment, Flatfight either stops its future renewals or cancels it immediately (for fraud), whichever you chose. It never refunds or prorates, leaves inquiries alone, and notes in the evidence that the cancellation came after the dispute.

No. By default every evidence package waits for you to click Submit. You can turn on autopilot, which submits only strong cases 48 hours before the deadline, and you can turn it off any time.

Turn off Smart Disputes auto-submission in your Stripe dispute settings. Otherwise Stripe may submit its own packet before you do, and evidence can only be submitted once. Flatfight warns you when Stripe is about to auto-submit.

Chargeflow charges 25% of each chargeback it recovers and covers many platforms, including physical-goods stores. Flatfight charges a flat fee per win ($9 or $19) or a flat monthly price, works only with Stripe, and is built for digital businesses whose best evidence is their own usage logs. Our comparison page covers when Chargeflow is the better choice, too.

Read access to disputes, charges, customers, invoices, subscriptions, products and checkout sessions, plus write access to disputes and evidence files. No payouts, balances, charges or refunds. The full list with reasons is on our security page.

No. Claude only sees the facts we gathered, every sentence must cite them, and a fact checker rejects anything that doesn't match. If it fails, we use plain template text built from the same facts.

We score every case and tell you when a win is unlikely. Accepting can save Stripe's $15 counter fee, which is refunded only when you win.

No one can: the card issuer decides every dispute. We make your evidence as complete and clear as your data allows.

Digital businesses on Stripe with meaningful ticket sizes: annual SaaS plans, online courses, coaching and agencies. The bigger your disputes, the more a percentage costs you, and the more a flat fee saves.

On servers in Helsinki, Finland (EU), encrypted at rest. Flatfight is operated by Dripwork, a Finnish business. You can export or delete your data at any time.

Flatfight emails you when a dispute arrives, and again 72 and 24 hours before it's due. With autopilot on, strong cases are submitted 48 hours before the deadline if you haven't acted. Medium and weak cases always wait for you. Disputes due within 72 hours can always be submitted, even past a monthly plan's limit.

Yes, with Flatfight Managed (done for you): our team handles every dispute from A to Z. We create the evidence (with custom integrations for the systems that hold it), check and submit each response within 2 business days, and tell you when a case is weak so you don't spend Stripe's counter fee on it. Priced for your volume, flat, never a percentage. Details at flatfight.com/managed.

A monthly plan runs to the end of the period you paid for, and there's no cancellation fee; on Pay per win there's nothing to cancel. Your disputes and evidence stay available, you can export everything, and deleting your account removes your data right away (encrypted backups roll off within 60 days). If you paid us anything, a short record of the agreement and payments is kept for 18 months for payment disputes, then deleted.
