Association software wanted for a music school

We are a music school (e.V.) and are looking for an association software that, in addition to functions such as member administration, planning management, data import/export and correspondence, should offer the following features in particular:

• Comprehensive contribution management with an automated control function of monthly teaching contributions to teacher fees.
• For example, we have family fees for 2 or more children with a discount. The discount difference must be taken into account when checking.
• Online banking

Note from SoftGuide:

With regard to the control function of the monthly tuition fees for teacher fees, corresponding inquiries are still ongoing with the providers. In our further research, we will concentrate on solutions specifically for music schools.
