The MSP vs in-house IT question comes up in almost every growth conversation we have with owners across New York and New Jersey. The short answer is that most conventional small businesses should start using professional outsourced IT support at roughly 10 employees, but they do not need a full-time internal IT employee anywhere near that size. Below is the threshold we use, the real cost math behind it, and the point where hiring internally actually pays off.
What does an MSP do?
A managed service provider delivers an entire IT function as a service, rather than a single person with a single skill set. For most small businesses, that covers a wider surface than any one hire could realistically own.
- Help desk and end-user support during business hours, with after-hours escalation
- Endpoint management, patching, and hardware lifecycle planning
- Network and firewall design, monitoring, and maintenance
- Cybersecurity tooling, monitoring, and incident response
- Microsoft 365 and cloud administration, identity, and access control
- Backup, disaster recovery, and business continuity testing
- Compliance support for frameworks such as HIPAA, SHIELD, and NYDFS
- Budgeting, roadmapping, and vendor management
You can see how we structure that work on our managed IT services page.
What does an internal IT employee do?
An internal IT employee is physically present, culturally embedded, and immediately available. That matters most in environments with constant hands-on demand or highly specialized software.
- Walk-up support, desk-side troubleshooting, and same-day hardware swaps
- Onboarding and offboarding staff, especially in high-turnover environments
- Deep knowledge of line-of-business applications specific to your industry
- Coordinating vendors, moves, buildouts, and multi-location logistics
- Serving as the internal owner of IT priorities and internal politics
The true cost of one internal IT employee
Owners usually compare an MSP invoice against a salary figure. That comparison is not accurate. Current labor data shows why.
- The national mean salary for a network and computer systems administrator was $103,680 in May 2025 (BLS occupational wages).
- In the New York and New Jersey metro area, computer and mathematical occupations averaged $67.04 per hour (BLS NY-NJ metro wages), which is roughly $139,000 per year at full-time hours.
- Benefits accounted for approximately 30.1 percent of private-industry employer compensation in March 2026 (BLS employer compensation).
Fully loaded cost illustration
Apply the 30.1 percent benefits load to a NY or NJ market wage and a single internal IT hire lands well above $170,000 per year in total employer cost before you add recruiting, training, certifications, management time, and the software and monitoring tools that person still needs in order to do the job. Internal IT costs in NY and NJ are consistently higher than national averages, which is why the threshold for hiring locally tends to arrive later than owners expect.
Employee-count decision table
This is the table we walk clients through when they ask about managed IT services vs internal IT.
| Company size | Recommended model |
|---|---|
| 1 to 9 employees | On-demand support or basic managed protection. Ad hoc break/fix is still workable at this size. |
| 10 to 74 employees | Fully managed IT provider. This gives you the widest coverage per dollar and is where professional support becomes necessary. |
| 75 to 100 employees | Evaluate an internal IT coordinator, kept alongside your MSP rather than replacing it. |
| 100 to 150 employees | Co-managed IT is frequently the strongest model as complexity grows. |
| 150 to 250+ employees | Consider a multi-person internal team, with specialized outside security support retained. |
Treat this as a practical threshold and not an absolute rule. Industry, compliance exposure, number of locations, and turnover can move it in either direction.
When an MSP is the better choice
Outsourced IT vs in-house IT is largely a question of coverage breadth per dollar. An MSP is the stronger choice when:
- You need security, backup, and help desk coverage at the same time
- Downtime during a single person's vacation or resignation is unacceptable
- You want predictable monthly cost instead of salary plus tooling plus turnover risk
- Your growth curve is uncertain and you need to scale support up or down
This is the profile of most small businesses we support across the tri-state region.
When an internal employee becomes valuable
An internal IT coordinator earns their cost when on-site presence and institutional knowledge become daily requirements rather than occasional ones.
- You are consistently above 75 users, or approaching 100
- You run multiple locations with physical infrastructure at each
- You depend on specialized applications that require hands-on administration
- Staff turnover creates a steady stream of onboarding and offboarding work
- Compliance and audit work needs a dedicated internal owner
The exceptions matter more than the average
A 40-person medical practice, CPA firm, property management company, or multi-location business may need an internal coordinator well before 75 employees. Compliance obligations, specialized applications, turnover, and constant on-site demands all pull the threshold earlier. Employee count is where the conversation starts, not where it ends. Our healthcare, CPA firm, and property management clients frequently fall into this category.
Why one IT employee is not an IT department
A widely used IT staffing ratio is approximately one IT employee per 50 to 75 users, a range supported by NinjaOne’s 2026 staffing analysis. The ratio is a useful planning input, but it hides an important limitation.
One person cannot simultaneously provide help desk, networking, cybersecurity, cloud administration, strategic planning, vacation coverage, and incident response. Those are distinct disciplines with distinct tooling and distinct on-call expectations. When a single internal hire is asked to cover all of them, three predictable things happen:
- Security and strategy get deferred because tickets are always more urgent
- Coverage disappears entirely during illness, vacation, or resignation
- The business becomes dependent on undocumented knowledge in one person’s head
A small business IT department that actually functions is either three or more people, or one person supported by an outside team.
How co-managed IT works
Co-managed IT services split responsibilities so each side does what it does best. In a typical arrangement:
- Your internal staff own walk-up support, onboarding, line-of-business applications, and internal project coordination
- We own security monitoring, patching and RMM tooling, firewall and network management, backup and recovery, after-hours escalation, and incident response
- We share budgeting, roadmapping, vendor management, and compliance reporting
The result is that your internal hire is no longer a single point of failure, and your business gets specialist depth without hiring three more people.
Decision checklist
Work through these questions before you post an IT job listing.
- Do we have daily on-site technology demands that remote support cannot resolve?
- Do we run specialized or compliance-bound applications that need a dedicated owner?
- Who covers nights, weekends, vacations, and resignations if we hire one person?
- Who owns cybersecurity monitoring and incident response after the hire?
- Would co-managed IT deliver the same outcome at a lower total cost?
- Do we have a documented IT roadmap this person would execute against?
If you answered no to the first three questions, an MSP is almost certainly the better use of the budget right now.

Frequently asked questions
How much does one internal IT employee really cost?
The national mean salary for a network and computer systems administrator was $103,680 in May 2025 according to BLS occupational wage data. In the New York and New Jersey metro area, computer and mathematical occupations averaged $67.04 per hour. Benefits accounted for approximately 30.1 percent of private-industry employer compensation in March 2026, so the fully loaded cost of one internal hire in NY or NJ is materially higher than base salary alone.
What is co-managed IT?
Co-managed IT is a shared model where your internal IT staff handle day-to-day, on-site, and application-specific work while an MSP supplies tooling, cybersecurity, after-hours coverage, escalation engineering, and strategic planning. It is frequently the strongest model between roughly 100 and 150 users.
Can a 40-person company need internal IT earlier than 75 employees?
Yes. A 40-person medical practice, CPA firm, property management company, or multi-location business may need an internal coordinator earlier because of compliance obligations, specialized line-of-business applications, staff turnover, or constant on-site demands. Employee count is a starting point, not the whole answer.
