Naturopathic practice seeks practice software, possibly with appointment scheduling

I am a naturopath and am looking for practice software for my naturopathic practice with four treatment rooms, which may also include appointment scheduling.

I have the following requirements for the software:

• Patient management
• Billing
• The ability to create your own billing chains
• With cash book according with the principles for the proper management and storage of books, records, and documents in electronic form, as well as data access
• Invoice creation
• Prescription creation with affiliated drug database
• Dunning
• Possibly with appointment scheduling for Windows
• Possibly data transfer from legacy system
• Server-client solution is desired; no web-based solution

Four to five software workstations are planned.
