Choosing between managed IT services vs in-house IT is one of the more consequential decisions a growing company can make—and it rarely gets the attention it deserves. Most businesses default to whatever they’ve always done, or hire based on immediate pain rather than long-term fit. That’s how teams end up with coverage gaps, unexpected costs, and support that doesn’t scale with the business.
This isn’t a question with a universal answer. But there are clear patterns that point one direction or the other, depending on your size, risk profile, and how much your operations depend on technology staying reliable.
What You’re Actually Comparing
On the surface, the comparison looks simple: one full-time IT person versus a monthly contract with an outside provider. In practice, the differences go deeper than headcount.
An in-house IT hire gives you someone physically present, dedicated entirely to your environment. That can feel reassuring—especially when something breaks and you want a person in the room. But one employee also means single-point-of-failure coverage. If they’re sick, on vacation, or leave the company, your IT support disappears with them. Their skills are also fixed. A strong help desk technician may not be equipped to manage your firewall, lead a cloud migration, or respond to a security incident.
A managed IT provider gives you a team—typically including help desk staff, network engineers, security specialists, and a project lead—all under one contract. You’re not paying for one person’s knowledge; you’re paying for the depth of a full team. The tradeoff is that they’re not physically in your office every day, and response times for non-urgent issues depend on how your agreement is structured.
Cost: What the Numbers Usually Show for 25–100 Employee Teams
For companies in the 25 to 100 employee range, this is where managed IT often has a clear advantage—though the math isn’t always obvious at first.
A single experienced IT hire in a major metro area typically costs $65,000 to $90,000 in base salary, plus benefits, payroll taxes, hardware, training, and turnover risk. That investment buys you coverage during business hours, one skill set, and one person’s availability.
A managed IT contract for a company the same size typically runs $3,000 to $8,000 per month depending on scope—which includes monitoring, help desk, patching, security tools, and after-hours coverage. The per-seat cost is predictable and scales with headcount.
The real cost comparison isn’t just salary vs. contract. It’s: what do you get for that spend, and what happens when something goes wrong at 7pm on a Friday? For most businesses at this size, a single in-house hire doesn’t answer that question adequately.
The common mistake here: companies factor in only base salary when budgeting for an in-house hire, then get surprised by the actual total cost—and still end up underserved in areas like security, backup management, and after-hours incidents.
Coverage Gaps That Create Real Business Problems
This is where the in-house model quietly fails companies who don’t realize it until something breaks.
Consider a 40-person professional services firm that relies on one IT generalist. He manages endpoints, handles tickets, and keeps the network running day to day. He’s capable and well-liked. Then he takes a two-week vacation. While he’s gone, a Microsoft 365 misconfiguration causes email routing failures for three of the firm’s client accounts. Nobody internal can diagnose it. A call to Microsoft support takes two days to resolve. Billable work stalls. A client escalates.
This scenario plays out regularly. It’s not a staffing failure—it’s a structural one. One person cannot provide the breadth of coverage a business needs across endpoints, cloud platforms, security, network infrastructure, and vendor coordination.
Managed IT providers are structured to avoid exactly this kind of single point of failure. Tickets get routed to whoever has the right expertise. After-hours monitoring means someone is watching your systems even when your office is closed.
How to Decide: Practical Questions for Non-Technical Leaders
Rather than asking “which is cheaper,” the better questions are:
- How much would one hour of full downtime cost your business? If the answer is “a lot,” you need a support model that takes uptime seriously—with monitoring, documented escalation paths, and after-hours response.
- Does your current IT setup have documented procedures? If the answer is “mostly in one person’s head,” you have a risk problem regardless of whether that person is in-house or external.
- What happens when your primary IT contact is unavailable? If the honest answer is “we wait,” that’s worth fixing.
- Are your systems actively monitored, or do you find out about problems when staff complain? Reactive IT support is a different product than proactive managed services, even if both are called “IT support.”
For companies operating across multiple locations, the calculus shifts further toward managed IT. Maintaining consistent standards, software, and security policies across two or three offices is genuinely difficult to manage with a single hire who can only be in one place.

When In-House IT Still Makes Sense
In-house IT isn’t always the wrong choice. There are situations where it fits.
If your company has more than 150 to 200 employees with complex, custom infrastructure—proprietary applications, on-premise servers requiring daily hands-on attention, or a regulatory environment that demands an always-present IT presence—a dedicated internal team starts making more sense. At that scale, you can also hire specialists rather than generalists.
Some companies also run a hybrid model: a managed IT provider handles day-to-day monitoring, help desk, and security, while a single internal IT manager handles vendor relationships, internal projects, and strategic planning. This works well when the internal hire is senior enough to coordinate rather than execute everything themselves.
What This Means for Your Business
If you’re running a business with 25 to 100 employees and relying on one IT person—or on break-fix support when things go wrong—you’re likely carrying more operational risk than you realize. The gaps aren’t always visible until they become expensive.
The managed IT services vs in-house IT question is ultimately about coverage, depth, and what your business actually needs to stay reliable. For most companies at this size, a managed provider offers more consistent coverage at a more predictable cost.
