How do I receive money from BitPay?

Hello there, I'm curious about how I can go about receiving money through BitPay. Could you please explain the process in a step-by-step manner? Are there any prerequisites or specific steps I need to take in order to successfully set up a BitPay account and start receiving payments? Also, is there a fee associated with using BitPay for receiving payments, and if so, how is it calculated? Thanks in advance for your help!
