In-House IT vs. Managed IT: An Honest Comparison from People Who've Seen Both

In-House IT vs. Managed IT: An Honest Comparison from People Who've Seen Both

We're going to say something you might not expect from a managed service provider: in-house IT is the right answer for some businesses. Not most — but some. And pretending otherwise would be dishonest, which isn't how we operate.

So here's our actual, unvarnished take on when you should hire internal IT staff, when you should outsource, and what the real tradeoffs look like.

The Case for In-House IT

There are real reasons to have dedicated in-house IT staff. The main ones:

You Have Specialized, Complex Infrastructure

If your business runs on highly customized enterprise software, specialized manufacturing equipment with network-connected components, or proprietary systems that require deep institutional knowledge, an in-house person who lives and breathes your environment can be more effective than a generalist MSP technician who sees it once a quarter.

You Have Regulatory Requirements That Mandate Dedicated Staff

Some compliance frameworks and industry regulations expect — or require — dedicated internal IT or security personnel. Certain healthcare contracts and government programs have specific staffing requirements that an MSP arrangement may not fully satisfy.

You're Large Enough That the Math Works

At some headcount, the math shifts. When you have 200+ employees and complex enough infrastructure to keep two or three IT people genuinely busy full-time, building an internal team starts to make economic sense. You lose breadth of expertise, but you gain depth and availability.

The Case for Managed IT

For most businesses in the 20–200 employee range, managed IT offers something an internal hire simply can't: a team of specialists instead of a generalist.

When you hire a single IT person, you're betting that one human can be great at:

  • Help desk and end-user support
  • Network design and management
  • Cybersecurity and threat detection
  • Cloud infrastructure (Microsoft 365, Azure, AWS)
  • Compliance and regulatory requirements
  • Backup and disaster recovery
  • Hardware procurement and vendor management
  • Strategic planning and IT roadmapping

That person doesn't exist. Or if they do, they're burning out and updating their resume.

The Real Cost Comparison

In-House IT (1 person) Managed IT (MSP)
Annual cost $85,000–$130,000 (salary + benefits) $78,000–$150,000 (varies by size/scope)
After-hours coverage On-call (overtime) or none Included (24/7)
Vacation/sick coverage Nobody (or you) Full team, no gaps
Security expertise Generalist level Dedicated security team
Scalability Hire another person Adjust contract
Tool costs Separate line item Usually included

The dirty secret of the in-house IT math is that the salary is just the starting point. Add benefits (20–30%), recruiting costs when they leave (typically 20% of salary), tool and software licenses the person needs to do their job, training to keep their skills current, and the productivity hit while you're finding a replacement — and the real annual cost of one IT employee is often $120,000–$170,000.

The Coverage Gap Problem

Here's the thing about IT people: they get sick. They take vacations. They leave. When your only IT person is out — for any reason — you're on your own. That's fine when things are running smoothly. It's a disaster when your email goes down on a Friday afternoon and your IT person is at a wedding.

This isn't a hypothetical. We've gotten calls exactly like this. The solution in those moments is always to call an MSP. At which point the business owner usually asks: "Why aren't we just paying you people every month so this never happens?"

Good question.

The Hybrid Model

More common than pure in-house or pure managed IT is a hybrid: a company has one or two internal IT staff who handle day-to-day operations, onsite presence, and institutional knowledge — while partnering with an MSP for 24/7 monitoring, security, backup, and specialized expertise.

This works well for businesses in the 100–500 employee range. The internal team handles the human side — building relationships, understanding the business, being present. The MSP handles the infrastructure, security stack, after-hours support, and things that require specialist skills the internal team doesn't have.

The Honest Recommendation

If you have fewer than 75 employees: managed IT almost certainly makes more financial and operational sense than a dedicated in-house hire. You get more coverage, more expertise, and tools you couldn't afford to buy individually.

If you have 75–200 employees: it depends on your industry, your IT complexity, and your culture. The hybrid model often works well here.

If you have 200+ employees: you probably need some in-house IT staff regardless of whether you also use an MSP. The internal team provides relationship and institutional knowledge. The MSP provides scale and specialty.

If you're currently trying to decide, we'll tell you this: the most important thing isn't whether the IT person is on your payroll or ours. It's whether the work is actually getting done — the monitoring, the patching, the security, the backups. We've seen businesses with in-house IT that was genuinely excellent. We've also walked into environments where a company had an IT person on staff for five years and their backups hadn't been tested once. Title doesn't equal outcomes.
