Every growing company hits the same wall eventually: the office manager can't keep resetting passwords between other tasks, the server in the closet needs real attention, and someone has to own IT. The question is whether to hire your own IT staff or hand the job to a managed service provider (MSP). Both can work. The right answer depends less on philosophy and more on your size, your growth rate, and how much risk you're willing to concentrate in a single person.
This guide breaks down the real costs on both sides, the trade-offs that don't show up in a quote, and the hybrid model most companies end up running.
What an MSP actually gives you
An MSP runs your day-to-day IT for a flat monthly fee, usually priced per user or per device. Instead of a person, you get a team and a toolset:
- A helpdesk staffed by multiple technicians, so someone answers even when others are busy
- Remote monitoring and management tooling that patches and watches your systems automatically
- Backup management, vendor coordination and procurement support
- Processes refined across dozens or hundreds of client environments
- Coverage through vacations, sick days and staff turnover — theirs, not yours
The fee looks like a line item, but what you're really buying is redundancy: no single resignation, illness or vacation stops your IT support.
What hiring in-house actually takes
An in-house hire gives you something an MSP can't: a person who sits in your business every day, knows your systems and your people, and can be redirected at a moment's notice. But the true cost is more than the salary on the job posting.
- Fully-loaded cost: benefits, payroll taxes, equipment, training and certifications typically add 25–40% on top of base pay
- Recruiting: agency fees or months of search time, plus the risk of a bad hire in a field you may not be equipped to interview for
- Management: someone has to set priorities, review work and plan a career path, and in most small companies that someone is a busy executive
- Tooling: ticketing, monitoring, backup and documentation platforms that an MSP would have brought with them
- Coverage gaps: one person still takes vacation, gets sick and eventually quits, taking institutional knowledge with them
None of this argues against hiring. It argues for budgeting honestly.
The real cost comparison
| MSP | One in-house hire | |
|---|---|---|
| Annual cost | Predictable monthly fee, scaled to headcount | Salary plus 25–40% in benefits, taxes and overhead |
| Coverage | Team coverage, often with extended hours | One person, business hours, minus vacation and sick days |
| Breadth of skills | Helpdesk, network, cloud and projects across a team | Deep in some areas, thin in others |
| Knowledge of your business | Built over time, shared across their team | Deep and immediate |
| Continuity risk | Low: the provider absorbs turnover | High: one resignation resets everything |
| Management overhead | Review a monthly report and an annual plan | Recruit, manage, develop and retain an employee |
The honest comparison is rarely "MSP fee vs. one salary." It's "MSP fee vs. the first hire plus the backup plan for when they're unavailable." For most companies under 50 employees, a single hire costs more than an MSP and still leaves gaps. Somewhere past 100 employees, dedicated in-house staff usually earn their keep.
Beyond cost: coverage and continuity
Who answers at night and on vacation?
IT problems don't respect business hours, and neither do employees' lives. An MSP spreads that load across a team. A solo hire concentrates it in one person, which works until the email system fails during their two-week trip.
Depth vs. breadth
IT spans helpdesk, networking, cloud administration, security basics and vendor management. No single hire is strong in all of them. MSPs hire for breadth because they can spread specialists across many clients. In-house hires trade that breadth for deep familiarity with your environment.
The bus factor
When your only IT person leaves, passwords, network diagrams and vendor relationships can leave with them. Insist on documentation either way — it's simply easier to enforce with a contract than with an employee.
When each option wins
Five factors usually decide it.
Company size and growth
Under roughly 50 employees, an MSP is almost always more economical. Between 50 and 150, the hybrid model dominates. Past 150 to 200 with steady demand, a small in-house team, often still backed by an MSP for overflow and after-hours, becomes the norm. Fast growth favors MSPs because capacity scales without recruiting.
How central IT is to your product
If technology is your product — you run a SaaS platform, for example — in-house expertise is core to the business and worth investing in early. If IT is infrastructure that keeps the real business running, outsourcing it is like outsourcing payroll: sensible and common.
Compliance and security pressure
Regulated industries need documented processes, access reviews and evidence either way, and a good MSP helps with the IT side of that. Note that security monitoring and incident response are a separate decision from IT support entirely. Our MSP vs. MSSP comparison covers that distinction.
On-site vs. remote work
Mostly remote staff on cloud tools need little hands-on support, which favors an MSP. Offices full of hardware, conference rooms and printers create daily physical work that argues for someone on site.
Your appetite for managing IT people
Someone has to own the relationship either way. With an MSP, that's a vendor review cadence. With a hire, it's full people management. Be honest about which your leadership has the time to do well.
The hybrid model most companies land on
The most common end state isn't either-or. It's an internal owner, often an IT manager, plus an MSP doing the operational heavy lifting:
- In-house: strategy, budgeting, vendor oversight, business relationships, on-site presence where it matters
- MSP: helpdesk, patching, monitoring, backups, projects and after-hours coverage
This splits risk nicely: the company keeps control and institutional knowledge, while the MSP absorbs staffing churn in the trenches. If you go this route, put the division of responsibilities in writing, and be just as explicit about what happens in an emergency. A tested incident response plan is where those handoffs get defined before they matter.

Questions to ask before deciding
Work through these before you sign a contract or post a job. Vague answers, including your own, are a signal in themselves.
- What does the MSP quote actually include, and what gets billed extra?
- What would a fully-loaded first hire cost us, including tools, training and recruiting?
- How much hands-on, on-site help do we genuinely need each week?
- Who covers IT when our person is on vacation, sick or gone for good?
- How fast are we growing, and what does IT demand look like in two years?
- Who will manage IT priorities and vendors if we outsource, and who manages the hire if we don't?
- What happens to our documentation, admin credentials and data if we change providers, or if the hire leaves?
- Who handles security monitoring and incident response under each option?
Frequently asked questions
How many employees justify a first in-house IT hire?
A common range is 50 to 100 employees, but the real triggers are when your MSP bill approaches the fully-loaded cost of a hire, when you need hands-on help on site most days, or when IT decisions need someone who lives in your business full time.
Can one IT person replace an MSP?
Rarely. One hire gives you presence and deep knowledge of your environment, but can't cover vacations, sick days and after-hours issues, and won't span helpdesk, network, cloud and security alone. Most first IT hires work alongside an MSP rather than replace one.
Does an MSP cover security too?
Baseline hygiene, yes: patching, antivirus management and MFA rollout are standard. Round-the-clock threat monitoring and incident response, usually no. That is what an MSSP or MDR service provides, and it is a separate buying decision.
Key takeaways
- Compare an MSP's fee against the fully-loaded cost of a hire, not just base salary.
- One hire gives depth and presence but no redundancy; an MSP gives breadth and continuity.
- Under roughly 50 employees, MSPs usually win on cost; past 150, in-house teams usually earn their keep.
- The hybrid model, an internal owner plus an MSP for operations, is the most common end state.
- Whichever you choose, document responsibilities, credentials and incident handoffs in writing.
