You get what you pay for. I cannot stress this enough. Using a "Free" solution may leave you with bad support or none at all. Community support is not the same thing as 24/7 access to a Premium Support Channel, or Account Manager.
If someone asked you to pay for a Managed Solution for your company and informed you that the backbone of their business is built off of a freebie open source product with no support...would you start thinking to yourself "Oh yea that sounds like a great idea, let's pay these guys $$$$ a month!"
Do you have clients right now that are interested in managed services? If so, have you proposed anything yet, and are they ready to sign?
If you have not even come up with your proposal, agreement, or what solutions you're an expert at managing...you have a long road ahead of you. If you do it solo, you'll lose lots of time. If you engage the right partner companies, you can cut down on that time tremendously and jump right to the heart of things. If you're not a competitor, I would be more than happy to send you information on how to quickly establish a good roadmap to establish a new managed services IT company. Just PM me.
If you've made a proposal, but they're not ready to sign:
1. Continue to market to them EVERY month, sit with them and discuss their needs so you and your client's vision of their business needs line up, and find solutions that you can provide to them
2. Start to demo RMM & PSA's in your free time, when you're NOT marketing your company
3. Sign them to an agreement once you find a KILLER Solution/Offering
If they're ready to sign:
1. Get 50% of the project work to get them up-to-speed upfront at the day you sign them
2. Buy your RMM and get it into production (this will take a few days, onboarding, and then a few weeks to get familiar with things)
I use Labtech in my company, and they gave me my first month for free. If your plan of action is timed properly, you can start your MSP with ZERO overhead, MRR already coming in from signed clients, and get the first month of your RMM for free.
Other idea's you should consider.
1. Have your clients pay for your overhead
2. Hire a pro to manage your RMM when you can. Every RMM tool I've used has a Admin you can hire to help you manage everything, and develop a good RMM roadmap for your company. I highly suggest you do this initially to save yourself time and money. When you're familiar with the tool later on, drop the service if you want, and bring all of the Admin work in-house.
3. Hire a Help Desk Service to manage your endpoint systems. You can get most of them for anywhere between $6-20/mo./endpoint. Factor it into your billing so that YOU'RE not handling Tier 1-2 issues anymore.
