Answer: Since the introduction of version 3, A tempo has been available in 4 editions: A tempo Institute, Deluxe, Special, and basic.

The Deluxe edition has some important features , such as Departments, Department Sections, Invoicing and multiple Teacher accounts. If you need those features, you should get the Deluxe. However, if none of those features is of use to you, you will be happy with the basic edition, which has many improvements, new features, and a cheaper price. Of course, all the improvements and new featurese are also found in the Deluxe edition.

If you find that the organizing of Classes by Section is useful to you, but you don't have other teachers working with you and don't need invoicing, then the Special Edition may be just what you need.

If you find the use of Departments useful, or you have more than 1 teacher in the studio, or you give out invoices occasionally, or you like to see how much a student owes on his account (that would be "receivables"), you definitely should consider getting A tempo Deluxe.

If you have several rooms or locations for teaching, with several teachers, or you organize workshops for students from outside your studio, you should consider the Institute edition.
