Choosing between managed IT services vs in-house IT is one of the more consequential decisions a growing company will make—and most businesses get it wrong not because they chose poorly, but because they never made a deliberate choice at all. They just kept patching together whatever worked at the time.
If you have between 20 and 200 employees, this decision directly affects your uptime, your security posture, your budget predictability, and how quickly your team gets help when something breaks. Here is a practical breakdown to help you think it through.
What You Are Actually Comparing
In-house IT means hiring one or more employees whose job is to manage your technology. Managed IT means contracting with an external provider who takes on that responsibility for a monthly fee.
Both models work. The question is which one fits your size, your budget, and the complexity of your environment right now.
A single in-house IT person at a 40-person company carries a heavy load. They handle the help desk, manage your network, maintain your servers or cloud environment, deal with security, support new hires, troubleshoot Microsoft 365 problems, and respond to anything that breaks after hours. That is a wide scope for one person, and it creates real risk. When that person leaves, takes a vacation, or simply does not know how to solve a specific problem, your business feels it.
A managed IT provider brings a team. You get a help desk with multiple technicians, engineers with specialized expertise, and documented processes—without paying multiple full-time salaries.
The Real Cost Comparison
The sticker price for managed IT can feel high until you do the math properly.
An experienced in-house IT hire in Dallas or Austin typically costs $60,000 to $90,000 per year in salary alone, before benefits, payroll taxes, training, and equipment. And that still leaves gaps—one person cannot cover everything, especially cybersecurity and after-hours support.
Managed IT contracts for a company in the 30 to 100 employee range typically run significantly less than the total cost of a comparable in-house hire, and they include services that would otherwise require additional vendors: endpoint monitoring, backup management, security tools, help desk ticketing, and strategic planning.
The blind spot most companies miss: they compare the managed IT monthly fee against the IT employee’s salary, but they forget to account for the full loaded cost of employment—and they rarely factor in what happens when IT issues go unresolved because one person is stretched too thin.
Where In-House IT Has a Genuine Advantage
In-house IT is not the wrong answer for every company. There are situations where it genuinely makes more sense.
If your business has highly specialized systems—proprietary software, complex manufacturing equipment, or industry-specific platforms—an in-house IT person who knows that environment deeply can be more effective than a generalist MSP team.
Companies with 150 or more employees often benefit from having at least one internal IT resource who understands the business, manages vendor relationships, and sits in on operational planning. In those cases, the better model is often co-managed IT: an internal IT manager or coordinator who handles day-to-day relationships and strategic decisions, while the MSP provides the technical depth, help desk coverage, and specialized expertise.
If you are at that stage, IT support strategy for small businesses covers how to think about dividing those responsibilities effectively.
Common Mistakes Businesses Make With This Decision
Waiting until something breaks. Most companies do not revisit their IT model until they have already experienced a serious problem—a breach, a prolonged outage, or a difficult employee departure that left no documentation and a pile of unanswered questions. By that point, the cost of fixing things is always higher than the cost of planning ahead.
Assuming an IT employee means better service. Response speed depends on workload and process, not employment status. An overwhelmed in-house IT person may take longer to resolve a ticket than a managed provider with a staffed help desk and escalation procedures. If your staff regularly waits hours for basic IT help, that is a workflow problem—not something that automatically gets better just because the IT person is full-time.
Treating IT like a cost center instead of a reliability function. Operations managers often focus on minimizing IT spend without quantifying what downtime actually costs. A two-hour outage that affects 30 employees is not just an inconvenience—it is a measurable productivity loss. When you frame it that way, the monthly cost of proactive IT support looks very different.
Not accounting for coverage gaps. In-house IT typically means Monday through Friday, standard business hours. If your systems go down on a Friday evening before a big Monday deadline, your in-house IT person may not engage until Monday morning. Most managed IT agreements include 24/7 monitoring and after-hours escalation. That coverage gap is easy to overlook until you need it.
Practical Questions to Help You Decide
Before committing to either model, work through these questions honestly:
- How often does your team experience IT issues that go unresolved for more than a few hours? If this is a regular occurrence, your current model is not working—regardless of whether it is in-house or outsourced.
- Do you have documented processes for IT onboarding, offboarding, and incident response? If the answer is no, this is a process gap, and a managed provider will typically build that structure as part of their engagement.
- What happens if your IT person leaves tomorrow? If the answer involves significant disruption, vendor confusion, or lost access to systems, you have a single-point-of-failure problem.
- Are you growing? Adding locations, staff, or new applications creates IT complexity quickly. A managed provider can scale with you without requiring you to hire additional IT staff each time.
- What does your cybersecurity coverage look like? Security is a specialized discipline. Very few in-house generalists have the depth to manage endpoint detection, patch management, email filtering, and incident response at a professional level without significant additional tooling and ongoing training.

What This Means for Your Business
There is no universal right answer between managed IT services vs in-house IT—but there is a right answer for your situation based on your size, your budget, and your operational risk tolerance. The mistake is not choosing one over the other. The mistake is not choosing deliberately.
If you are a 20 to 100 person company still relying on a single IT person or a break-fix arrangement, the managed IT model almost always offers better coverage, more predictable costs, and fewer gaps. If you are larger and already have internal IT staff, co-managed IT is worth considering seriously.
Either way, your IT structure should match the demands your business actually places on it—not the demands it placed three years ago.
