## Bank, ACH & check disputes

These use different reasons, and not all are won with evidence:

* `debit_not_authorized` — treat like an unauthorized/fraud dispute; provide proof of authorization.
* `incorrect_account_details`, `bank_cannot_process` — usually processing failures, not evidence disputes. Correct the details and re-attempt collection where possible.
* `check_returned`, `insufficient_funds` — funding failures. Recover payment through another method rather than contesting.
