Managed IT Services vs. In-House IT: A Real Cost Comparison for 10-50 Person Firms

If you run a growing firm in San Mateo County, you’ve probably had this conversation more than once: should we hire an in-house IT person, or outsource to a managed IT services provider? It’s a fair question. The honest answer is that cost drives the decision, though not the cost people expect first. The salary line on a budget is easy to compare. The full picture is a lot messier, and for firms in the 10–50 person range, it usually points in one direction.

What in-house IT really costs

Let’s start with the number everyone quotes. A solid IT support hire in the Bay Area runs $85,000–$130,000 in base salary, not to mention benefits, payroll taxes, and overhead on top. That’s still before recruiting costs, which for a technical role in this market can easily run into five figures.

There’s another cost that doesn’t show up on the budget line: one person can only be in one place. When they’re on vacation, your help desk is closed. When they’re firefighting an outage, your strategic projects stall. No single hire brings equal depth across security, cloud infrastructure, compliance, and day-to-day support. You end up paying a generalist salary for coverage that still has gaps. For a 30-person accounting firm or law office, that’s a lot of money for a lot of single points of failure.

What managed IT services actually include

A managed service provider (MSP) works on a predictable monthly per-user fee — typically $125–$200 per employee per month for a firm of your size. For a 25-person firm, that’s roughly $40,000–$60,000 a year, and it covers a lot more than one person ever could:

• A full team, not a single hire — help desk coverage during business hours, specialists in security, cloud, and networking, and no coverage gap when someone takes a day off
• Proactive monitoring and maintenance, so problems get caught and fixed before they become downtime
• Security built in — patch management, endpoint protection, multi-factor authentication, backup and disaster recovery, and support for compliance requirements like CPRA
• Predictable budgeting — one flat monthly line item instead of surprise project costs, emergency invoices, and turnover-driven re-hiring expenses

The comparison math gets pretty stark: a fully loaded in-house hire costs two to three times what a managed IT contract runs for most 10–50 person firms, and the MSP brings more people, more expertise, and more hours of coverage.

When in-house still makes sense

To be fair, there are situations where hiring internally is the right move. Firms with highly specialized, proprietary systems, or those large enough to justify a full IT department with a director and staff, can build real advantages in-house. Additionally, some firms use a hybrid model with one internal person who knows the business deeply, backed by an MSP for security, after-hours coverage, and specialized projects. That hybrid setup is increasingly common among professional services firms in San Mateo, is Burlingame, and Foster City, and it often delivers the best of both worlds when feasible.

The bottom line

For most 10–50 person firms in the Bay Area, managed IT services deliver broader expertise, stronger security, and predictable costs at a fraction of what a single in-house hire truly runs. The question isn’t really “can we afford an MSP?” — it’s whether you can afford the gaps that come with a team of one.
