I was by no means suggesting that you charge your clients what I charge mine. Every location or area is different and it is up to us to uncover what any particular market will pay for our managed services.
I could move my business 1 hour east, and the appropriate niche there would easily pay double the amount I'm currently charging for this particular service.
The point is use the process of adding more value to what you offer so that your clients are willing to pay you more.
That is a suggestion, for sure, but how do you define your clients? What makes a client a business client and what makes a client a residential client?
My primary client base is SMBs or very small SMBs with one or no server. I also have residential clients that appreciate and understand the need for constantly updated computers, anti-malware software, and cloud backup. In the end, all of my clients have one thing in common; they just want it to work.
As an MSP I have several tools that I rely on to fit my customer's needs, and I tailor each of my plans to best meet the needs of my clients. One plan (or tool) does not fit all and Kabuto has found a place with my smaller clients.
I'm not suggesting that you do it my way, but take whatever you can use, and leave the rest.
