Hey there @gil06000,
One thing that you can do is charge the current user, and then schedule something from the API Connector to pay out the payee at a time of your choosing, by which the payee should have registered. If they haven’t registered in that time, the money won’t be sent to the payee.
By using the API Connector instead of Bubble’s built-in method of sending money to payees, you can control exactly when the money gets sent.
You can learn how to set up an API call that manually pays out payees in this new video tutorial for Stripe.
