I like the MINDBODY Online Software for small businesses because it has accompanying apps that help you schedule and take payments on the go (Mindbody express) and one for your current clients or future clients to schedule classes on (Mindbody connect)
The price varies depending on the size of your business but the company is helpful and I find the software to be user friendly.
Yours in health & happiness,
