Choosing between managed IT services vs in-house IT is one of the more consequential decisions a growing company makes — and most leadership teams make it without a clear framework. They either inherit whatever was in place before, or they react to a crisis. Neither approach tends to work out well.
This guide is built for companies in the 25–200 employee range that are asking this question seriously, often for the first time.
What You’re Actually Comparing
Before getting into trade-offs, it helps to define what each model actually involves in practice.
In-house IT means hiring one or more employees whose job is to manage your technology. At smaller companies, this is often a single person — sometimes someone who drifted into the role from another job. At larger companies, it might be a small team. Either way, you own the full cost of those salaries, benefits, training, and coverage gaps (vacations, turnover, sick days).
Managed IT services means contracting with an external provider that takes on responsibility for your IT environment — monitoring, maintenance, security, help desk, and often strategic planning — for a predictable monthly fee.
There’s also a third path worth knowing about: co-managed IT, where an internal IT person or team works alongside an outside provider. This model suits companies that have outgrown one IT generalist but aren’t ready to build a full department.
The Real Cost Comparison
Salary is the most visible cost of in-house IT, but it’s rarely the full picture.
A competent mid-level IT generalist in a major metro area costs $65,000–$95,000 per year in salary alone. Add benefits, payroll taxes, recruiting costs, and time spent on hiring and you’re looking at significantly more. If that person leaves — and turnover in IT roles is high — you absorb a full recruiting cycle while your systems run unmanaged.
Managed IT typically runs on a per-user or per-device pricing model. For many companies in the 25–100 employee range, total monthly costs land between $1,500 and $6,000 depending on scope and service level. That fee covers a team, not a single person.
The cost comparison isn’t always obvious in favor of one option. What managed IT consistently does better is cost predictability. You know what you’re spending. You’re not surprised by an emergency hardware replacement or a $15,000 recruiting push when your IT person quits.
For companies where cash flow planning matters — and for most owner-operated or mid-market businesses, it does — that predictability has real value.
What In-House IT Does Well (and Where It Falls Short)
In-house IT has genuine advantages. An internal hire learns your business, your quirks, your staff. They build relationships. If your environment is highly specialized — proprietary software, complex compliance requirements, custom infrastructure — someone embedded in your company can develop deep institutional knowledge that’s hard to replicate.
But most companies with one IT generalist are running that person ragged. They’re handling password resets in the morning and trying to evaluate backup software in the afternoon. Strategic thinking rarely happens because reactive work never stops.
Here’s a common scenario: a 60-person professional services firm has one IT manager. When a Microsoft 365 issue prevents the accounting team from accessing shared files for half a day, that person is pulled away from a planned server upgrade. The upgrade gets pushed back. Three weeks later, the server runs into a problem that the upgrade would have prevented. The business loses a full day of productivity — and the IT manager loses sleep.
One person cannot simultaneously be a help desk technician, a security analyst, a systems administrator, and a technology strategist. But that’s often what small businesses expect.
What Managed IT Does Well (and Where It’s Not the Right Fit)
A managed IT provider brings depth. Instead of one generalist, you get access to specialists — someone who focuses on security, someone who handles network infrastructure, someone who manages cloud environments. When an issue escalates beyond the help desk, it moves to the right person.
Proactive monitoring is another genuine differentiator. A good managed IT provider watches your systems around the clock and addresses issues before they become outages. That’s not something one internal hire can realistically do.
For companies with multiple locations, the advantage is even clearer. Network issues that affect a satellite office don’t wait for business hours, and they often stem from something invisible to anyone without monitoring tools in place.
That said, managed IT isn’t the right answer for every situation. If your business runs on highly specialized or custom-built systems that require someone on-site daily, or if you’re in an industry where a dedicated internal team is a regulatory or operational necessity, the managed model has real limitations. Some companies also find that a less experienced managed provider treats them like every other client — standard playbook, minimal customization.
The quality of the provider matters as much as the model itself.
The Decision Criteria That Actually Matter
Rather than asking “which is cheaper,” ask these questions:
How often do IT problems affect your staff’s ability to work? If the answer is “regularly” and you have an in-house person, the model may not be the problem — but the resources available to that person likely are.
Do you have a single point of failure? If one person is responsible for everything and they’re unavailable, what happens? Many businesses don’t have a clear answer until something goes wrong.
Is your IT approach reactive or planned? If you’re only thinking about technology when something breaks, that’s a structural problem either model can worsen if you’re not deliberate about it.
What’s your growth trajectory? A company adding 20 employees per year needs IT infrastructure that scales. Managed IT contracts can scale with headcount. Hiring does not flex as cleanly.
Do you have specialized compliance requirements? HIPAA, PCI-DSS, and similar frameworks require specific controls. Some managed providers specialize in these areas; others don’t. This is a critical question to ask before signing anything.
A Common Mistake to Avoid
One of the most frequent mistakes leadership teams make is assuming that adding a managed IT provider means their internal IT person becomes redundant. That’s not always true — and firing a competent internal hire to save money often backfires.
If you have an internal IT person who knows your environment well, a co-managed arrangement lets them focus on the work that requires that knowledge while the managed provider handles help desk volume, monitoring, and after-hours coverage. The internal person stops being stretched across everything and becomes significantly more effective.
What This Means for Your Business
There’s no universal answer to the managed IT services vs in-house IT question. The right choice depends on your size, your growth rate, your risk tolerance, and the complexity of your environment.
What is clear is that the “call when something breaks” approach has a ceiling. Once your operations depend heavily on technology — and for most companies today, they do — you need consistent coverage, not ad hoc responses.
