When a customer pays you online in the client portal, you will get your money one of two ways.
If they pay by PayPal, the money will go into your PayPal account. From your PayPal account they let you transfer to your bank account (sometimes instantly).
If they pay using Stripe it will be deposited into the checking account you added when you set up your account with Stripe. The first deposit takes 7 days then they deposit every day after that.
