For most businesses under about 50 employees, outsourced managed IT costs less than a single in-house technician once salary, benefits, tools, training, and coverage gaps are counted, and it delivers broader skills and after-hours support the lone technician cannot. Between 50 and 150 employees, the honest answer is usually co-managed IT: one internal person for hands-on and institutional knowledge, backed by an outsourced team for security, projects, and coverage. Above that, a real internal department starts to make sense, often still with outside specialists.
In-house IT vs outsourced IT: what the salary number leaves out
Owners compare a technician's salary to a managed services quote and conclude the hire is cheaper. The comparison is incomplete. A fully loaded internal IT position includes:
- Salary and payroll costs. Employer taxes, health insurance, retirement match, and paid time off typically add a widely reported 25 to 35 percent on top of salary.
- Tooling. Remote monitoring, endpoint security, backup software, email filtering, password management, documentation, and ticketing are all subscriptions a managed provider already owns and spreads across many clients. An internal hire has to buy them at single-company prices.
- Training and certifications. Technology changes fast; a technician who is not learning is falling behind, and that costs time and money.
- Recruiting and turnover. Good technicians are in demand across the Treasure Coast, and replacing one takes months during which the business is exposed.
- Management time. Someone has to supervise, prioritize, and evaluate the position, and that person usually does not have an IT background.
- Coverage gaps. One person is available roughly 220 working days a year, during business hours. Vacation, sick days, and evenings are uncovered. Ransomware and hurricanes ignore the schedule.
- Skill breadth. No single person is expert in networking, security, Microsoft 365, servers, cloud, compliance, and phones. An internal generalist will be strong in some and learning the rest on your systems.
What does a managed IT provider include?
A typical managed services agreement for a small business is a per-user or per-device monthly fee covering help desk, monitoring, patching, endpoint security, backup management, vendor coordination, and regular reviews, with after-hours emergency coverage. Projects such as a server replacement or an office move are usually quoted separately. The provider brings a team with specialists, a mature toolset, documented procedures, and, in the good cases, a strategic role through vCIO services that an internal technician rarely has time for.
The honest downsides: you share the team with other clients, so during a regional event such as a hurricane everyone needs help at once; institutional knowledge of your quirks lives in documentation rather than in a person down the hall; and if the provider is poor, the relationship is harder to fix than a single employee's performance. Vetting matters.
A worked comparison: 25-seat company
Consider a 25-person professional office in Vero Beach: cloud email, a line-of-business application, a few servers or hosted equivalents, and compliance pressure from insurers.
In-house
One mid-level technician. Add the payroll burden, the tooling subscriptions bought at retail, training, and some management time. Coverage is business hours only, with no backup when the person is out. Security, compliance, and project work are done to the best of one generalist's ability, or contracted out anyway.
Managed IT
A per-user fee covering the full stack and 24x7 emergency support. Total cost is usually well below the fully loaded cost of the hire, and the business gets a team rather than a person. At this size, the fully loaded internal hire is typically the more expensive option by a clear margin, and the coverage is worse.
Verdict at 25 seats: outsourced managed IT wins on cost, coverage, and skill breadth. An internal hire only makes sense if the role includes substantial non-IT duties.
A worked comparison: 75-seat company
Now a 75-person organization, perhaps a multi-location medical group or a manufacturer in St. Lucie County, with more devices, more applications, and daily hands-on needs.
In-house
Two people at minimum to provide coverage: a technician for daily support and a more senior administrator for systems and security. Fully loaded, that is a significant six-figure annual commitment before tooling, and it still lacks deep specialists and true after-hours coverage.
Managed IT
The per-user fee scales with headcount, so the monthly number is larger than the 25-seat case, but it remains competitive with two fully loaded salaries plus tooling. The risk is that daily hands-on tasks, such as walking to a workstation on the shop floor, are slower than having someone on site.
Co-managed IT
One internal technician handles daily support, hardware, and the relationships; an outsourced team provides monitoring, security operations, patching, backups, projects, after-hours coverage, and escalation. The internal person gets a team behind them and time off without exposure. This is frequently the lowest total cost at this size because it avoids the second senior hire while keeping someone on site. Our co-managed IT service is designed for exactly this situation.
Verdict at 75 seats: co-managed usually wins, with fully outsourced a close second for organizations without shop-floor or clinical hands-on demands.
Is outsourced IT cheaper than in-house IT?
For businesses under about 50 seats, almost always, once the costs are fully loaded. Between 50 and 150 seats, the cheapest and most resilient model is often a hybrid. Beyond 150, an internal department becomes cost-effective for daily operations, though specialists for security, cloud, and compliance are still commonly outsourced. Anyone who tells you one model is always cheaper is selling that model.
Questions that decide the answer for your business
- How much hands-on, on-site work is there every day? Warehouses, clinics, and shops with equipment need presence; offices mostly do not.
- What happens when your one IT person is on vacation during a ransomware event?
- Do you need security and compliance expertise that a generalist will not have?
- Are you buying tools at retail that a provider already owns?
- Who is thinking about your IT strategy and budget a year out?
- What is your growth plan? The right model at 20 people may be wrong at 60.
