If you see a payout that you don't recognise, it could be from a platform or service that works with Stripe for payments. Platforms such as SquareSpace, Shopify or crowdfunding platforms such as Kickstarter accept payments and get paid using Stripe.
If you are unable to verify the source of the money deposited into your bank account, or if you need help getting in touch with a platform that you might have used to accept payments, contact Stripe support. For prompt assistance, provide support with details about the payment, including: payment amount, date received, routing number, last four digits of the account number, and the statement descriptor or a screenshot of your bank statement.
