Welcome to the forum @lzinga. You should try searching by title and post for key terms like “POS import” and similar services to Paypal like “Square” or “Clover.” This general topic has come up many times before, so there is a lot of information already out there, though, granted, they can be tough to find since they often specify a service provider or POS system.
I think this could be a good place to start; Square payments transferring into bank account. It concerns Square, but the basic approach is likely the same or similar.
