Amelia is a capable WordPress booking plugin and an excellent Booking Calendar alternative.
This versatile plugin offers enterprise-level booking functionality for repair centers, gyms, private clinics, and other appointment-oriented businesses.
One of the strong points of Amelia is its versatility. It supports multiple services, locations, and employees in order to accommodate diverse case scenarios.
It also has a very vibrant support team and keeps on churning out new features every now and then.
Just like Booking Calendar, Amelia is a competitively-priced plugin with lifetime plans ranging from $189 to $586. Both plugins also have freemium versions on the WordPress plugin marketplace, but the free version of Amelia does not appear to be as capable as that of Booking Calendar.
