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 there by accident rather than by plan. They hire their first IT person when things get chaotic, or they sign a managed services agreement after one too many outages. Neither approach is wrong by default, but choosing the wrong model for your size and situation will cost you in ways that aren’t always obvious upfront.
This guide is for businesses with roughly 25 to 100 employees that are actively weighing both options, or questioning whether their current setup is still the right fit.
What Each Model Actually Looks Like in Practice
An in-house IT hire means one or more employees whose full-time job is managing your technology. At smaller headcounts, this is often a generalist — someone who handles everything from resetting passwords to managing your server room. At larger headcounts, you might have a small team.
A managed IT provider is a third-party company you contract with to handle some or all of your IT needs. Depending on the agreement, that can include help desk support, cybersecurity monitoring, network management, backup oversight, and vendor coordination.
There’s also a middle path: co-managed IT, where an internal IT person or team works alongside an external provider. This is often the right answer for companies that have an IT manager but need additional coverage, specialized skills, or after-hours support they can’t staff internally.
The right model depends on a few things: how complex your environment is, how much downtime your business can tolerate, what your IT budget looks like, and whether your needs are steady or vary by season or growth phase.
The Real Cost of In-House IT at Small Scale
Hiring a full-time IT person makes intuitive sense. You want someone available, accountable, and focused on your business. The problem is what you actually get for that investment at the 25-to-50 employee range.
A mid-level IT generalist in Dallas or Austin runs $60,000 to $85,000 per year in salary alone — before benefits, payroll taxes, training, and turnover risk. For that, you get one person with one skill set, one schedule, and no backup when they’re sick, on vacation, or leave the company.
More importantly, a single IT hire typically can’t cover everything. Security monitoring, backup management, network troubleshooting, cloud administration, and help desk support are four different disciplines. When one person handles all of them, something usually gets neglected. The most common blind spot is backup testing — businesses assume their backups are working because no one has told them otherwise. A backup failure usually gets discovered at exactly the wrong moment.
This doesn’t mean in-house IT is wrong. It means the economics only start making sense once you have enough complexity, enough volume, and enough budget to staff it properly.
Where Managed IT Tends to Win
For most companies in the 25-to-100 employee range, a managed IT agreement provides coverage that’s difficult to replicate with one or two internal hires.
A few areas where the difference shows up in day-to-day operations:
- After-hours support. If your staff works outside normal business hours — or if a server issue surfaces at 9 PM — an in-house hire is not answering that call. Managed providers with a staffed help desk are.
- Multi-location environments. If you have offices in more than one location, coordination across sites, ISPs, and network configurations gets complicated fast. Managed providers handle this routinely.
- Vendor management. When your internet goes down, do you know exactly who to call, what your account numbers are, and how to escalate? Vendor coordination during outages is something a good managed provider handles on your behalf.
- Microsoft 365 administration. Most businesses assume Microsoft backs up their email and files. It doesn’t — not in the way most people expect. Licensing, configuration, and third-party backup for Microsoft 365 requires ongoing attention that often falls through the cracks without dedicated oversight.
A Common Mistake: Waiting Too Long to Reassess
One of the most frequent problems growing companies run into is sticking with a support model that made sense two years ago but doesn’t fit anymore.
A business that started with a break-fix IT vendor — someone you call when things break — often keeps that arrangement well past the point where it’s costing them. Break-fix works when your environment is simple and downtime is a minor inconvenience. It stops working when your staff relies on cloud applications, your data has real compliance sensitivity, or you’ve added a second location.
The sign that you’ve outgrown break-fix isn’t one dramatic failure. It’s the accumulation of recurring issues — the same Wi-Fi drops, the same Microsoft 365 sync problems, the same slow performance complaints — that never quite get resolved because your vendor only shows up when called.
Recurring IT problems are usually a process problem, not a device problem. A managed provider doing proactive monitoring catches these patterns early. A break-fix vendor only sees the symptom after it becomes an emergency.
If your team is filing the same support tickets month after month, that’s worth examining.
Practical Decision Guidance: Which Model Fits Your Situation
Use these scenarios as a rough guide:
Consider managed IT if:
- You have 25–75 employees and no dedicated internal IT staff
- You’ve had recurring outages or unresolved support issues in the past 12 months
- You’re planning an office move, significant hiring, or a new location
- Your current IT support has no defined response time or service agreement
- You’re unsure whether your backups have ever been tested
Consider in-house IT (or co-managed) if:
- You have 75–100+ employees with complex, specialized infrastructure
- You need an IT leader who can own vendor relationships and internal IT strategy
- You have an internal IT manager who needs deeper coverage or specialized support without replacing them
Consider co-managed IT if:
- You have one internal IT person who is overwhelmed or lacks specific expertise
- You need after-hours or weekend coverage you can’t staff internally
- You want to keep internal IT ownership but add a layer of security monitoring or backup management
For growing companies that are evaluating outsourced IT support options, the co-managed model is often underexplored. It’s worth asking about before assuming it’s a binary choice.
What This Means for Your Business
There’s no universal answer here, but there is a practical one: the right IT support model is the one that matches your current size, your risk tolerance, and your growth trajectory — not the one you defaulted into.
If your IT support hasn’t been formally reviewed in more than a year, that’s a reasonable place to start. Look at your open ticket history, your last incident, and whether your current setup has a documented disaster recovery plan or a tested backup. If the answer to any of those is unclear, that tells you something.
