When your business reaches 20-100 employees, IT decisions become critical to your bottom line and growth trajectory. The choice between managed IT vs in house IT isn’t just about preference—it’s about total cost of ownership, scalability, and business continuity. Recent industry data shows that most growing companies underestimate their true in-house IT costs by 30-40%, making this comparison more important than ever.
The Real Cost of Building an In-House IT Team
Building an internal IT department involves far more than just salaries. For a growing company with 25-50 employees, here’s what you’re actually looking at:
Staffing and Salary Costs
- IT Manager/Technician: $90,000-$150,000 annually
- Benefits and overhead: Additional 25-40% ($22,500-$60,000)
- Training and certifications: $2,000-$8,000 per person annually
- Recruitment costs: Often overlooked but can add $15,000-$25,000 per hire
Infrastructure and Technology Costs
- Initial setup: $50,000-$100,000 for basic infrastructure
- Annual maintenance and upgrades: $15,000-$25,000
- Software licensing (monitoring tools, security, backup): $20,000-$50,000
- Emergency repairs and unexpected expenses: Highly variable
Total annual cost for a 25-employee company: $150,000-$200,000
Hidden Costs That Add Up
Many business owners don’t account for the operational risks of in-house IT:
- Coverage gaps during vacation, sick leave, or staff turnover
- Limited expertise – one or two people can’t be experts in everything
- Slow response times outside business hours
- Scalability challenges when you need to grow quickly
Managed IT Services: A Different Cost Structure
Managed IT providers typically charge $100-$300 per user per month, depending on service level and complexity. This predictable monthly fee includes:
- 24/7 monitoring and support
- Cybersecurity management
- Backup and disaster recovery
- Help desk services
- Vendor management
- Proactive maintenance
- Access to specialized expertise
Cost Comparison by Company Size
25 employees:
- Managed IT: $36,000-$75,000 annually
- In-house IT: $150,000-$200,000 annually
- Savings: 50-70%
50 employees:
- Managed IT: $60,000-$150,000 annually
- In-house IT: $300,000-$450,000 annually (2-3 staff members)
- Savings: 60-75%
Why Managed IT vs In House IT Matters for Growth
Growing companies face unique IT challenges that make the managed service model particularly attractive:
Scalability Without Hiring Delays
When you need to add 20 new employees quickly, managed IT can accommodate growth within weeks. In-house hiring typically takes 3-6 months, creating dangerous coverage gaps during expansion periods.
Access to Specialized Expertise
A managed IT provider gives you access to:
- Network engineers for complex infrastructure needs
- Cybersecurity specialists for threat protection
- Cloud experts for migration and optimization
- Compliance professionals for regulatory requirements
Building this expertise in-house would require a team of 5-10 people for most growing companies.
Reduced Downtime Risk
Industry data shows managed IT clients experience 85% less downtime compared to reactive in-house support. When downtime costs the average business $427 per minute, this difference is significant for your profitability.
When In-House IT Makes Sense
While managed services work better for most growing companies, in-house IT might be right if you have:
- Highly specialized or proprietary systems that require deep internal knowledge
- Strict compliance requirements that mandate on-site control
- 100+ employees with complex, custom infrastructure needs
- Sufficient budget for a full IT team (typically $500,000+ annually)
Hybrid Approach: Best of Both Worlds
Some growing companies choose a co-managed model:
- Keep 1-2 in-house staff for daily operations and business alignment
- Partner with a managed service provider for specialized expertise and 24/7 coverage
- Scale the partnership up or down based on business needs
This approach works well for companies with 50-150 employees who want some internal control while maintaining cost efficiency.
Making the Decision: Key Questions to Ask
Before choosing between managed IT vs in house IT, consider:
1. What’s your true total cost of ownership over 3-5 years? 2. How quickly do you need to scale your IT capabilities? 3. What level of expertise do you need across different technology areas? 4. Can you afford the risk of coverage gaps during staff changes? 5. Do you want predictable monthly costs or variable expenses?
What This Means for Your Business
For most growing companies with 20-100 employees, managed IT services deliver better value, reduced risk, and improved scalability at a fraction of the cost of building an internal team. The key is choosing a provider that understands your business goals and can grow with you.
The managed IT vs in house IT decision ultimately comes down to your specific needs, budget, and growth plans. However, the financial data strongly favors the managed approach for companies in rapid growth phases who need reliable, comprehensive IT support without the overhead of multiple full-time hires.
