Hello Marcin,

Thanks for reaching out to us and for your interest in Amelia.

Please, find the answers below

1. Does Amelia operate on WP Users? Or does it have separate table with users details? I remember it was quite a mess to manage the users and employees. Can the User with Administrator role become an employee as well?

There are two separate options for managing WP users and Amelia User (Customers). The same rule is still applied, two users should have different user roles and different emails. In other words, an admin can't be the employee at the same time and vice versa. You want to keep them separated (with different emails and user roles)

      2. Is it possible to make Amelia replicating details given in booking form (first name, last name, email) into WooCommerce checkout fields? It is super annoying for Users who must enter those details again

Unfortunatelly, this is the same, and customers still need to enter their credentials on the WooCoomerce checkout. This is because, from the moment when the booking is finished in Amelia, the whole payment process is forwarded to WooCoomerce (and that's a separate window)

Anyway, you can always purchase our license and test it out since we have a 15-day money-back guarantee period. (I guess you are already familiar with this)
