The knowledge sources only mention paying Mixpanel via credit card, which is charged at the beginning of each month or year for your subscription. [Billing & payment]
They do not mention bank transfers or any alternative payment methods, so I can’t confirm that bank transfer is supported. To check available options for your specific account, you’d need to:
- Go to Organization Settings → Plan Details & Billing → Manage Billing & Payment and see what payment methods are offered there, or
- Contact Mixpanel Support or Sales directly for confirmation.
