Why did you become a managed services provider (msp)? 

Of all the things you could be doing with your business, you chose to build a business that delivers proactive monitoring and management services for IT systems and resources used primarily by small and medium sized businesses. That sounds like a sound business strategy. As a principal characteristic, you are paid on a recurring contract basis to deliver services that could have previously been done by customer IT staff or other outside resources on a reactive time-and-materials basis.
