…We are now able to have the resources of a big company, but don’t have to pay full price for them…If there is an issue, we don’t have to do anything but call them. They are easy to deal with and their staff does whatever they have to do to get issues resolved.

I've contacted XL for IT support with various issues and assorted software and apps, throughout the workday and off hours. They have consistently been incredibly responsive, helpful, friendly, and professional, and they help me understand the problems in layman's terms. Thanks XL!

Appraisal Institute provides me and my business every tool we need to succeed and a peace of mind that can’t be bought. What we pay now is less than what we were paying before – with a side of extra competency. We are getting better services for less.
Illinois Ventures
Compared to our previous provider, the transition to saves us $7,000 – $8,000 a month in IT expenses and the fact that we no longer have an in-house IT tech. This is the best IT vendor I have had experience with – and I’ve had a lot of experience with IT vendors in the past.
The biggest thing XL helps us with is to manage our time. Everyone’s busy and we can’t solve the problems ourselves, so having XL as a resource to take over when we don’t know how to handle tech issues ourselves is very helpful.

Overall, we’ve had a great experience with XL. Everyone is very personable. We don’t have any negative feedback because we’ve had a great experience. I have no issue picking up the phone and calling someone at XL. I always feel very comfortable. XL makes things that I wouldn’t want to deal with smooth and easy to deal with
Emily D
I am very confident in XL’s team, enthusiasm, and knowledge. I know that when I reach out to them, I can get an answer and a fast resolution.

If they didn’t have the answer, they dug for a solution. That’s what gives us confidence in working with them.

I can tell that XL is growing. I see that new names are popping up on their tech roster. Each of them must be going through a great training program because they are all top-notch.
