Right-Sized Support for Businesses That Don't Have an IT Department.
Addison isn’t a corporate campus town. It’s a dense, diverse mix of small and family-owned businesses, auto dealers and repair shops, warehousing along Lake Street, and light manufacturing, run by owners who wear five different hats before lunch. Computerease has supported businesses like these since 1984, and we size our plans for a 10-person shop the same way we would for a much larger company: seriously, not as an afterthought.
Computerease provides managed IT support, cybersecurity, cloud, and phone systems for small and mid-sized businesses in Addison, Illinois. Founded in 1984 and led today by Ryan Haislar, CISSP, the company supports automotive, retail, warehousing, healthcare, and professional service businesses throughout Addison and the surrounding western suburbs.
Addison doesn’t have one dominant employer or a single industry that defines it. It has hundreds of small businesses: auto dealerships and repair shops along the Lake Street and Route 53 corridors, warehousing and light manufacturing tucked into industrial pockets, and a genuinely diverse mix of family-owned retail and service businesses. A lot of national IT providers build their plans around a mid-sized enterprise and then try to shrink them down to fit a smaller business. That approach rarely fits well.
We built our Addison service the other way around, starting from what a small, owner-operated business actually needs: reliable systems, real security, and a technician who picks up the phone and already knows how your business runs.
A lot of small Addison businesses are still calling someone only after something breaks, then losing a half day waiting for a callback. Our ConstantCare Managed IT Services program is built to catch problems before they cost you a workday.
Keep your entire team productive and secure working from any location.
Utilize the power and functionality of Microsoft 365 for your business.
Tech experts are available 24/7/365 to help address any problems.
Services: printer support without surprise supply bills.
practical guidance on where AI tools genuinely help a small business.
it’s exactly what we built our approach to fix. Computerease builds security into every plan instead of selling it as an expensive upsell, using the Center for Internet Security (CIS) Critical Security Controls as the foundation.
Our CISSP-led team has direct experience helping small automotive, retail, and warehousing businesses close the security gaps attackers count on finding, without requiring an in-house IT hire to manage it.
Small business owners in Addison don’t have time to sort AI hype from AI that actually helps. We do that work for you with AI Readiness Assessments, employee AI training, secure Microsoft Copilot deployment, and AI Acceptable Use Policies that give your small team clear rules without a legal department to write them.
Some Addison businesses have grown enough that one person, sometimes the owner, handles IT on the side along with everything else. Our co-managed model backs that person up, taking on advanced cybersecurity and 24/7 monitoring so it isn’t riding on one overloaded person’s shoulders.
Not every Addison business is independently owned. Some of the warehousing and light manufacturing operations here are the local branch of a company headquartered elsewhere, sometimes elsewhere in the U.S., sometimes overseas. Corporate IT may set the company-wide standards and manage the major infrastructure, but a local site still needs a partner on the ground for day-to-day support, onsite troubleshooting, new-hire equipment setup, and coordination with headquarters. Computerease works alongside internal and international IT teams to provide that local layer of support while staying aligned with whatever standards headquarters has already set. Whether your headquarters is in London, Frankfurt, Toronto, or another U.S. city, our role is to be dependable local hands and eyes, working as an extension of the IT team you already have.
We manage Microsoft 365 environments on an ongoing basis, not just at setup, and handle migrations off an aging on-premise server to Microsoft Azure when it’s time to retire that hardware. No IT department required on your end.
Our cloud-based phone systems keep a small team connected whether they’re behind a counter, on a shop floor, or working from home. Same number, same features, no expensive phone hardware to maintain.
Our office is well positioned to reach Addison and the surrounding western suburbs, with both remote and onsite support available.
Service area spans western DuPage County and connects with our Oak Brook and Elk Grove Village coverage nearby.
Computerease | Big-Package IT Vendors | |
Fit for a small business | Plans sized to a 5 to 50-person business, not padded for a big contract | Cookie-cutter enterprise packages priced for someone else’s business |
Response time | 15 minutes or less for critical, system-down issues | A slow ticket queue that treats small accounts as low priority |
Security ownership | A CISSP builds and owns your strategy directly | Security is often a generic add-on module |
Agreement structure | One year to start, then month-to-month by choice | Multi-year terms with early exit penalties |
Company structure | Family-owned, second generation, since 1984 | Often a franchise or private-equity-backed rollup |

I have been with Computerease for many years. They have a great team of I.T. techs, whether it is on the phone or coming to my office. They are fast and efficient.
We are a small business and have been a Computerease client for years. I highly recommend their services for large and small firms. Always extremely efficient with their response times and very knowledgeable on all things computers/systems!
I have to say, these guys and girls are the BEST! They are there for every question and issue, always with the perfect resolution. We reach out to them often just exploring options with our systems. Computerease always makes our lives easier! We love them!!
Deep knowledge of systems hardware, Microsoft OS and many software platforms. Very responsive when we have issues. Computerease never leaves us hanging. A true partner for a company like ours that does not have in-house IT support. I give them my highest recommendation.
Dan was incredibly kind, patient, and helpful — hands down the easiest laptop transition I’ve had in over 20 years! I was able to work all day while he handled everything, and he also got our conference room tech running smoothly. Everything feels easier and better than our old setup — the Computerease team is really good.

If your current IT setup feels like it was built for a much bigger business, or your team keeps running into the same problems, it’s worth a second look. Our free assessment includes:
Built for a small business from the start. We don’t take an enterprise plan and strip out features, we design support around what a 10 to 50-person business actually needs.
We aim to respond to system-down, business-critical issues in 15 minutes or less. Our help desk is staffed by real technicians, not an automated queue.
Yes. We support dealership management systems, service scheduling, and secure customer data handling for automotive businesses.
Not at all. Most of our small business clients don’t have an internal IT person, that’s exactly why they work with us. We handle it all, and explain things in plain language when you have questions.
Clients start with a one-year initial agreement. After that, most continue month to month because the relationship holds up on its own.
A national provider often treats a small business account as an afterthought. We don’t. You get a technician who knows your business, not a rotating cast of strangers.
