Setting up seller account with multiple people

Hi I’m looking to set up an account with a friend, who I’ll be running the account with. What’s the best way to set up the finances? We currently have a joint revolut account that we intend to buy our products using but I was wondering if connecting that account to the Amazon seller account to get deposits from would cause any issues? How would Tax work as well in this instance? Is there a better way to set this up?
