The Managed IT vs Co-Managed vs In-House talk is often goes unconsidered before it’s too late. Your IT person just put in their two-week notice. Or maybe they haven’t yet, but they are the only one who knows the Wi-Fi password, the backup schedule, and where the firewall documentation lives. For a 50-person company, that single point of failure is not a hypothetical risk. It is Tuesday.
Choosing between managed IT services, co-managed IT, and building an in-house team comes down to coverage, cost predictability, and what happens at 2 a.m. when a server stops responding. This guide breaks down all three models so you can see which one fits your business today and where it is headed next.
Key Takeaways: Managed IT vs Co-Managed IT vs In-House IT
- Managed IT replaces an entire IT department with a dedicated external team for a fixed monthly fee.
- Co-managed IT keeps your internal staff and adds after-hours coverage, security depth, and specialist support.
- In-house IT provides full control but requires multiple hires to cover nights, weekends, and specialized skills.
- WheelHouse IT delivers both managed and co-managed IT with pod-based teams assigned to your environment.
- For a 50-person company, the right model depends on whether you already have internal IT staff.
Managed IT vs Co-Managed IT vs In-House IT: Overview
What Is Managed IT?
Managed IT means an outside provider operates your entire IT function. Help desk, monitoring, patching, backups, security, and strategic planning all fall under one team. You pay a fixed monthly fee and get a full bench instead of one person.
The provider owns every layer of support, from password resets to compliance documentation, so there is no gap when someone is sick or on vacation.
Managed IT Key Features
- 24/7 monitoring and help desk: A staffed operations center watches your systems around the clock, not just during business hours.
- Fixed monthly cost: One predictable fee replaces the unpredictable mix of salaries, tool licenses, and emergency contractor bills.
- Layered security: Endpoint detection and response, email filtering, and threat monitoring are built into the service.
- Compliance support: Audit-ready documentation for frameworks like HIPAA and PCI is maintained year-round, not assembled during an audit.
- Strategic planning: A technology roadmap aligned to your business goals, reviewed on a regular schedule.
Managed IT Pros and Cons
Pros:
- Coverage does not stop when an employee resigns, takes PTO, or calls in sick.
- WheelHouse IT delivers managed IT with a reported average call wait time of 52 seconds and an average ticket resolution of 29.6 minutes.
- Fixed-fee pricing makes IT spending predictable month to month, with no surprise invoices.
Cons:
- You have less direct day-to-day control over IT priorities compared to an in-house employee sitting next to you.
- The provider needs time to learn your specific applications and workflows during the initial onboarding period.
- Some businesses in highly specialized industries may need supplemental on-site support for proprietary equipment.
What Is Co-Managed IT?
Co-managed IT keeps your existing internal IT staff in place and pairs them with an outside provider that fills specific gaps. Your IT person handles the daily support and business context. The provider takes on the work your internal team cannot cover alone: overnight monitoring, security operations, patching, and specialist projects. Nobody gets replaced.
Co-Managed IT Key Features
- Shared scope with defined boundaries: A written scope document spells out where your team’s responsibility ends and the provider’s begins.
- After-hours and weekend coverage: Your internal staff stop carrying the pager because the provider handles nights and weekends.
- Access to specialist depth: Security, cloud, and compliance specialists are available without additional hires.
- Tooling and platform access: Your internal team gets access to enterprise-grade monitoring and management tools.
- Mentoring and escalation: Internal staff have a direct escalation path to engineers with deeper expertise, plus access to structured end-user training programs.
Co-Managed IT Pros and Cons
Pros:
- Your internal IT person retains the institutional knowledge, vendor relationships, and business context that an outside provider cannot replicate overnight.
- Internal staff move from firefighting to projects that grow the business because the tactical load shifts to the provider.
- Coverage gaps during vacations, sick days, and resignations are eliminated because the provider absorbs those hours.
Cons:
- The model requires a clear scope document. Without one, both sides may assume the other owns a task, and the gap surfaces during an incident.
- Your organization still carries the salary and benefits cost of the internal hire alongside the provider fee.
- Coordination between two teams requires regular check-ins and defined communication channels to avoid duplication.
What Is In-House IT?
In-house IT means your organization directly employs the people responsible for technology. You hire a help desk technician, a systems administrator, an IT manager, or a full department depending on size. Your team sits in your office and knows your business inside out.
The tradeoff is straightforward. Coverage is limited to what your headcount can sustain, and at 50 employees that headcount is usually one person.
In-House IT Key Features
- Full control over priorities: You direct every project, escalation, and purchasing decision without going through an outside provider.
- Deep business knowledge: An employee who sees your operations every day understands workflows that an outside team has to learn.
- On-site presence: Hardware issues, cabling, and physical infrastructure get hands-on attention without scheduling a visit.
- Direct accountability: Your IT staff answers to your leadership team, with no intermediary contract between you.
- Proprietary system expertise: For environments with custom applications or specialized equipment, in-house staff develop deep familiarity over time.
In-House IT Pros and Cons
Pros:
- You maintain direct control over staffing, priorities, and the technology roadmap.
- Internal staff build institutional knowledge about your applications and people that compounds over time.
- On-site presence makes physical infrastructure work, from server room access to cabling, faster.
Cons:
- A single IT hire for a 50-person company creates a single point of failure. When that person resigns, coverage drops to zero until the role is filled.
- Providing 24/7 monitoring requires at least three full-time staff to cover shifts, which is rarely realistic for a company this size. Adding disaster recovery and backup testing to that workload stretches the generalist even further.
- The 2025 ISC2 Cybersecurity Workforce Study found that 88% of organizations experienced a security consequence tied to a skills shortage. One generalist cannot be a security analyst, a cloud architect, and a compliance specialist at the same time.
Managed IT vs Co-Managed IT vs In-House IT: In-Depth Comparison
Coverage and Availability
Managed IT and co-managed IT both provide 24/7 monitoring from a staffed operations center. The difference is who handles daytime support. With managed IT, the provider owns the entire help desk. With co-managed IT, your internal team handles daily requests and the provider covers nights, weekends, and escalations.
In-house IT, for a 50-person company, typically means one or two people working business hours. After-hours coverage requires on-call stipends or overtime, and there is no backup when both people are out. That gap is where incidents turn into outages.
Cost Predictability
Managed IT operates on a fixed monthly fee that bundles help desk, security, monitoring, and strategic planning into one number. WheelHouse IT structures this as a flat-fee, month-to-month program for qualified organizations, so you can forecast your IT budget without long-term contract lock-in.
Co-managed IT adds a provider fee on top of your internal salary costs, but the combined total is often lower than hiring a second or third person. In-house IT looks cheaper on a spreadsheet until you add benefits, tool licensing, training, recruiting costs, and the overtime that follows every after-hours incident.
Security Depth
A managed IT provider typically staffs dedicated security engineers and runs a managed security stack that includes endpoint detection and response, email protection, and threat monitoring. Co-managed IT brings that same security depth to organizations that already have internal staff but lack the specialized skills.
In-house IT relies on whatever your hire happens to know. The 2025 ISC2 Cybersecurity Workforce Study reported that 95% of organizations have at least one cybersecurity skill need. A single generalist protecting a 50-person company is filling multiple specialized roles with one person’s time.
Scalability
Managed IT and co-managed IT scale through scope adjustments. Adding a new office, onboarding 30 employees, or expanding into a second state is a conversation, not a hiring cycle.
WheelHouse IT assigns dedicated pod-based support teams to each client. The people who know your environment are the same people who handle the growth.
In-house IT scales by hiring. That means recruiting, interviewing, onboarding, and ramping, a process that typically takes two to four months. During that window, your existing team absorbs the extra load, which is the same staffing math that created the gap in the first place.
Compliance Readiness
For businesses in healthcare, financial services, or legal, compliance evidence needs to exist before the auditor asks for it. Managed IT providers that support regulated industries maintain documentation year-round. WheelHouse IT has completed a SOC 2 examination, audited against AICPA standards by an independent CPA firm, and maintains HIPAA-aligned controls for healthcare clients.
Co-managed IT splits compliance responsibility in writing so both your team and the provider know who produces which evidence. In-house IT puts the full documentation burden on your staff, and that work often gets deferred until an audit is already scheduled.

Why WheelHouse IT Is the Best Choice for a 50-Person Company
Most 50-person companies land in one of two spots. Either nobody owns IT, and the office manager resets passwords while the CEO calls a friend when something breaks. Or one person carries everything, and the projects that would move the business keep sliding.
WheelHouse IT built both its managed IT and co-managed IT programs around those two realities.
What separates WheelHouse IT from the typical provider is structure, not promises. Every client gets a dedicated pod-based support team that learns your environment, your applications, and your people.
That team is backed by an internal 24/7 Network Operations Center staffed by WheelHouse IT employees. Calls are answered in a reported average of 52 seconds. Most tickets are resolved in a reported average of 29.6 minutes. Over 95% of clients rate their satisfaction above the threshold. Those numbers come from WheelHouse IT’s own service data, measured and published.
WheelHouse IT operates on a flat-fee, month-to-month model for qualified new clients. There is no extended commitment required.
That structure exists because a provider confident in its work does not need a cancellation penalty to retain clients. If you are ready to see which model fits your business, start with a complimentary risk assessment and get a clear picture of where your IT stands today.
FAQs: IT Support Models for a 50-Person Company
What is the difference between managed IT and co-managed IT?
Managed IT means the provider operates your entire IT function, from help desk to security to strategic planning. Co-managed IT means your internal staff stay in place, and the provider fills the gaps they cannot cover alone, like overnight monitoring and specialist security work.
Is in-house IT cheaper than outsourcing for 50 employees?
Rarely. A single fully loaded IT hire covers business hours only, and the total cost of salary, benefits, tool licensing, and recruiting typically exceeds what people expect. Add on-call stipends and turnover costs, and the total often surpasses a managed IT contract that provides 24/7 coverage from a full team.
Can I switch from one model to another?
Yes. Companies move between models regularly. A business that hires its first IT manager often shifts from managed to co-managed IT. WheelHouse IT offers month-to-month programs, so the commitment does not lock the decision in.
How does WheelHouse IT handle after-hours support?
WheelHouse IT staffs an internal 24/7 Network Operations Center with its own employees. After-hours calls go to the same pod-based team that handles your daytime support, not to a subcontracted call center or an overseas queue.
What happens to compliance if I switch IT models?
Under managed IT with WheelHouse IT, the provider owns the security controls and produces the audit evidence. Under co-managed IT, the split is defined in a written scope document before the engagement starts. Either way, the compliance obligation stays with your organization, and WheelHouse IT supports the readiness, documentation, and controls.
Does co-managed IT replace my internal IT person?
No. Co-managed IT is built to keep your internal team and extend their reach. Your staff handle daily support and business context. The provider takes overnight monitoring, patching, and Microsoft 365 administration off their plate so they can focus on higher-value projects.
