When your business reaches that critical growth phase—somewhere between 20 and 200 employees—the question of managed IT services vs in house IT becomes unavoidable. Your current IT approach that worked for 10 people won’t scale to 50, and what works for 50 may not handle 150.
This isn’t just about cost. It’s about business continuity, security coverage, and operational efficiency. The right IT structure reduces downtime, prevents security incidents, and keeps your team productive. The wrong choice creates bottlenecks, increases risk, and burns out your people.
Cost Reality: Beyond the Sticker Price
When comparing managed IT services vs in house IT, most business leaders focus first on the obvious numbers. But the real costs run deeper than salary versus monthly fees.
In-house IT costs for a mid-level generalist typically run $84,000 to $135,000 annually when you factor in salary, benefits, payroll taxes, and time off. Add another $5,000 to $25,000 for the security tools, monitoring platforms, and training they need to do their job effectively.
That single hire covers help desk, system administration, security monitoring, cloud management, and strategic planning. It’s a lot for one person.
Managed IT services typically cost $100 to $200 per employee per month for comprehensive coverage. For a 50-person company, that’s roughly $60,000 to $120,000 annually—often less than one fully-loaded internal hire while providing access to an entire team of specialists.
The hidden costs matter too. Internal IT means recruiting, managing performance, covering vacation time, and handling turnover. When your one IT person leaves, you lose institutional knowledge overnight and scramble to find coverage.
Staffing Challenges That Kill Productivity
The single point of failure problem hits growing businesses hard. One IT person handling everything means no coverage during vacation, illness, or the inevitable burnout from wearing every hat. Your help desk, security monitoring, and project work all stop when that person is unavailable.
Managed IT providers solve this with team redundancy. Multiple technicians know your environment, and 24/7 coverage means issues get addressed even when your internal team would be off-duty. You’re not managing IT hiring, performance reviews, or the specialized knowledge required for modern business technology.
For businesses in the 20 to 100 employee range, building a properly staffed internal IT team often means hiring multiple roles—help desk technician, systems administrator, security specialist. That’s a significant investment in overhead and management bandwidth.
Expertise Gaps That Create Risk
Modern business IT requires expertise across help desk support, network administration, cloud services, cybersecurity, and compliance. A single internal hire—even a strong generalist—cannot stay current in every domain while also handling daily support tickets.
Security represents the biggest expertise challenge. Cyber threats evolve constantly, and effective protection requires:
- Continuous monitoring and threat detection
- Incident response capabilities
- Compliance documentation and reporting
- Regular security awareness training
- Advanced security tools and platforms
Most growing businesses cannot justify hiring dedicated security staff, but they cannot afford security gaps either. Managed IT providers typically include enterprise-grade security tools, 24/7 monitoring, and incident response as part of their standard service.
The Hybrid Approach
Many successful businesses in the 50 to 200 employee range choose a hybrid model:
- One internal IT manager who understands the business, owns strategy, and manages vendors
- Managed IT support for growing businesses handling monitoring, help desk, security operations, and infrastructure management
This structure provides business alignment and vendor management internally while accessing specialized expertise and 24/7 coverage externally.
Scalability During Growth Phases
Business growth creates IT complexity fast. Adding locations, remote workers, new applications, and integration requirements can overwhelm a small internal team. Growth spurts result in slower response times, longer resolution periods, and more downtime when IT cannot keep pace.
Managed IT services scale smoothly with per-user pricing that adjusts as you add or remove staff. Providers can ramp up support during rapid growth, mergers, or major projects without requiring you to hire additional internal staff or manage workforce planning for specialized roles.
Internal IT scaling means budget approval processes, recruitment cycles, and training periods. Each new hire represents a significant fixed cost that may not align perfectly with your growth timeline or business needs.
Security and Compliance Requirements
Cyber insurance requirements and customer security questionnaires increasingly demand documented policies, security awareness training, incident response plans, and evidence of protective controls. Small internal IT teams often lack the bandwidth to maintain comprehensive security programs while handling daily operational tasks.
Professional managed IT providers typically include:
- Enterprise-grade endpoint detection and response (EDR)
- Email security and web filtering
- Backup and disaster recovery systems
- 24/7 security monitoring and incident response
- Compliance documentation and reporting
These capabilities would cost significantly more to implement and maintain internally, assuming you could find staff with the necessary expertise.
Making the Right Decision for Your Business
Consider managed IT services if:
- You’re in the 20 to 120 employee range without budget for multiple IT roles
- Security and compliance matter but you cannot justify dedicated security staff
- You have remote workers, multiple locations, or expect significant growth
- You’ve relied on one IT person and experienced coverage gaps or burnout
Consider more internal investment if:
- You’re approaching 150 to 200 employees and can afford a small internal team
- You have highly specialized systems requiring deep internal knowledge
- Regulatory requirements demand strict on-site control of systems and data
The hybrid model works well when:
- You need business alignment and vendor management internally
- You want comprehensive coverage without full internal overhead
- You value strategic IT planning combined with operational efficiency
What This Means for Your Business
The managed IT services vs in house IT decision shapes your operational efficiency, security posture, and growth capability. The right choice reduces downtime, prevents security incidents, and frees your leadership team to focus on business objectives rather than IT management.
Most growing businesses find that managed IT services or a hybrid approach delivers better coverage, expertise, and scalability than trying to build comprehensive internal capabilities. The key is choosing a provider that aligns with your business needs and growth trajectory.
