At some point, every growing business faces the same question: hire someone in-house to handle IT, or bring in a managed IT provider? Both models work. The right answer depends on your size, your budget, and what you actually need IT to do for your business. This post breaks down the real cost and tradeoff differences so you can make a clear decision.
What You Are Actually Comparing
The most common mistake in this comparison is treating it as a salary versus an invoice. That framing misses most of what matters. A single in-house IT hire gives you one generalist working 40 hours a week, with one area of expertise, during business hours. A managed IT provider gives you a full team with specialists across security, networking, cloud, and compliance, plus enterprise-grade tooling and 24/7 monitoring.
Those are not equivalent things at the same price point. The right question is not “which costs less on paper” but “what does your business actually need covered, and which model covers it?”
If you’re not yet clear on what a managed provider actually delivers day to day, the breakdown of what managed IT services include covers the full scope before you start comparing it to an internal hire.
The Real Cost of In-House IT
A network or systems administrator earns a median salary of $96,800 per year, according to BLS data (2024). Add benefits, payroll taxes, health insurance, paid time off, and annual training, and the fully loaded cost of a single IT hire typically runs $130,000 to $150,000 per year. That number is often a surprise to business owners who are only looking at the salary line. [1]
Beyond the base cost, you’re also taking on coverage risk. One person covers 40 hours a week. When they’re sick, on vacation, or leave the company, your IT coverage goes with them. IT employee tenure in small and mid-sized businesses averages under three years, according to CompTIA workforce research, which means turnover is not a rare event. Replacing an IT employee costs $15,000 to $25,000 in recruiting, onboarding, and lost institutional knowledge. [2]
Whether that investment makes sense depends heavily on what you get in return. The post on whether managed IT services are worth it walks through the value calculation from the other direction.
The Real Cost of Managed IT Services
A comprehensive managed IT package typically runs $100 to $200 per user per month, depending on the scope of services and the size of your business. For a 50-person company, that puts you somewhere between $60,000 and $120,000 per year, fully covered, including monitoring, security, helpdesk, and patching.
What’s bundled into that monthly rate matters as much as the number itself. Enterprise-grade tooling like remote monitoring and management (RMM) software, endpoint detection, and security information and event management (SIEM) platforms would cost tens of thousands per year to license independently. With a managed provider, those tools are part of the package.
If you see pricing under $100 per user per month, look carefully at what’s actually included. At that price point, you’re usually getting monitoring only, with helpdesk and security sold as add-ons. For a full breakdown of what drives pricing, the guide on managed IT services cost covers what to expect at different price tiers.
Where In-House IT Actually Wins
Managed IT is the right model for most small businesses, but not all of them. There are real scenarios where in-house IT has a genuine edge, and it’s worth being honest about them.
Businesses with more than 100 employees, complex on-site infrastructure, or proprietary systems that require deep institutional knowledge often benefit from having internal IT staff. A hospital with custom clinical software, a manufacturer with specialized production systems, or a law firm with a complex on-premise document management environment may need someone who has spent years learning exactly how those systems behave.
Physical presence is also a real advantage in certain environments. When hardware fails on-site, response time matters. A managed provider can remote in immediately, but if a server needs to be physically rebooted or a cable needs to be replaced, someone has to be there. For businesses where that comes up regularly, the case for at least some on-site IT capability is stronger. If you have internal IT staff already and are wondering how to extend their coverage, the guide on co-managed IT services describes how the hybrid model works.
The Hybrid Option: Co-Managed IT
Co-managed IT is the middle path most businesses don’t know exists. In a co-managed arrangement, your internal IT person handles the work that requires knowing your business: helpdesk support, user relationships, and business application management. The MSP handles the rest: 24/7 monitoring, security, patch management, compliance, and escalation when things go beyond one person’s bandwidth.
The sweet spot for co-managed IT is typically small-to-medium businesses with 50 to 200 employees, with one to three internal IT staff. At that size, you have enough complexity to need more than one person can handle alone, but not so much that building a full internal IT department makes financial sense.
If your internal IT person is drowning in tickets and can’t get ahead of anything, co-managed IT often provides better coverage at a lower cost than hiring a second full-time person. You get the specialist expertise and 24/7 coverage without doubling your headcount cost. See how the model works in practice in the full breakdown of co-managed IT services.
How to Decide: 3 Questions to Ask Yourself
If you’re still weighing the options, three questions cut through most of the noise.
First, how many employees do you have? For businesses under 75 people, managed IT almost always wins on cost when you count all the expenses. You’re getting broader coverage, better tooling, and no single point of failure for less than the fully loaded cost of one hire.
Second, do you run specialized or proprietary systems that require deep on-site knowledge? If the answer is yes, a fully managed model may not be the right fit on its own. A co-managed or hybrid arrangement, where an internal person handles the specialized systems and the MSP covers security and monitoring, often works better for these environments.
Third, does 24/7 coverage matter to your operations? If your business runs outside of normal business hours, whether that’s e-commerce, healthcare, manufacturing, or anything that can’t wait until Monday morning, you need coverage that doesn’t stop at 5 pm. The most expensive IT mistake is waiting until after a security incident to re-evaluate your model. By then, the average cybersecurity incident for an SMB under 500 employees costs $3.31 million, according to IBM’s 2025 Cost of a Data Breach Report. That figure tends to change the conversation quickly. [3]
See Which Model Makes Sense for Your Business
The managed IT vs. in-house IT decision comes down to cost, coverage, and complexity. For most businesses with 75 to 100 employees, managed IT covers more for less. For larger businesses or those with specialized systems, a hybrid model often strikes the right balance. And for businesses already running internal IT that’s stretched thin, co-managed IT is usually the most cost-effective path forward.
Systems Integration works with small and mid-sized businesses across Connecticut and New England to figure out which model fits their situation and build from there.
