MSP vs internal IT: which is right for your business?
An independent, numbers-first comparison of outsourcing to a managed service provider versus building an in-house IT team — what each really costs, where each wins, and why most growing companies end up somewhere in between.
For most businesses under 50 employees, a managed service provider delivers broader coverage and deeper expertise for less than the cost of one internal hire. Larger or specialized organizations often build an in-house team, and many mid-market firms choose a co-managed model that blends both.

The real question is fit, not just cost
“Should we hire IT or outsource it?” is one of the most common operational questions a growing business faces — and it is usually framed as a simple cost contest. It is not. The honest answer depends on your size, how much you depend on technology, your security and compliance obligations, and how much in-person, dedicated attention your environment needs.
There are really three options on the table, not two. You can build an internal IT team of employees who work only for you. You can outsource to a managed service provider (MSP) that runs your IT for a recurring fee. Or you can run a co-managed arrangement, where a lean internal team handles day-to-day needs and an MSP supplies after-hours coverage, security operations, and specialist depth. Most companies past about 50 employees end up in that third category, even if they started at one of the poles.
This guide compares the two pure models head-to-head — on cost, coverage, expertise, scalability, and risk — then shows where the co-managed middle path fits. If your main question is simply how much an MSP charges, start with our MSP pricing guide; if you have already decided to outsource and need to choose a provider, see how to choose an MSP.
The mistake that frames it wrong
Comparing one internal hire’s salary against an MSP’s monthly fee is the wrong comparison. One person cannot cover a helpdesk, security operations, strategy, and 24/7 monitoring at once — so the real choice is between a team you build and a team you rent. Compare capability and coverage, not headcount against invoice.
Definitions
What each model actually means
Before comparing them, it helps to be precise about what you are buying in each case, because the three models cover very different ground.
Internal IT
Employees on your payroll whose job is to run and support your technology — anything from a single “IT person” at a small company to a full department with a director, system administrators, network and security engineers, and a helpdesk. You pay salaries, benefits, training, and the tools they use. Their advantage is dedication: they know your business intimately, sit on-site, and answer only to you.
Managed service provider (MSP)
An outside firm that operates some or all of your IT for a predictable recurring fee, usually billed per user or per device. A good MSP brings a whole bench — helpdesk, engineers, security specialists, and a virtual CIO (vCIO) — plus the monitoring, patching, backup, and security tooling already in place. You trade some control and on-site immediacy for breadth, 24/7 coverage, and a cost that scales cleanly with headcount.
Co-managed IT
A hybrid where your internal staff and an MSP split the work by design. The internal team owns what benefits most from dedication and context — floor support, vendor relationships, knowledge of your line-of-business systems — while the MSP supplies the things that are hard to staff in-house, such as a 24/7 security operations center (SOC), after-hours coverage, and surge capacity for projects. It is the default for mid-market companies that have outgrown a single model.
The real numbers
The true cost of each model
A salary figure is not the cost of internal IT. The real number is fully loaded — benefits, payroll taxes, paid time off, tooling, training, and recruiting — and it buys the coverage of exactly one person. Here is what a single mid-level internal hire typically costs in 2026, before you have covered a single night or weekend.
| Cost component | Typical 2026 annual range | Notes |
|---|---|---|
| Base salary (system administrator) | $70,000–$105,000 | Helpdesk-only runs lower; senior or security roles run higher |
| Benefits, payroll tax, PTO | + ~30% | Health, retirement, employer taxes, paid leave |
| Tools & software | $12,000–$30,000 | RMM, PSA/ticketing, backup, and a security stack |
| Training & certifications | $3,000–$8,000 | To keep one person current across many domains |
| Recruiting & onboarding | $5,000–$15,000 | One-time per hire; repeats with turnover |
| Fully loaded, one person | ~$110,000–$175,000 / yr | Business-hours coverage only; a single point of failure |
Now set that against an MSP. Fully managed IT typically runs $75 to $200 per user per month in 2026 (compliance-heavy practices reach $250 to $300), with a one-time onboarding fee of one to three times the monthly rate. For a 30-person company at roughly $125 per user, that is about $45,000 a year — less than the loaded cost of one mid-level hire — and it buys a whole team with 24/7 monitoring rather than one person who takes vacations.
Why the dollar math usually favors the MSP
Across most of the SMB range, outsourcing wins on raw cost because you are spreading a shared team across many clients instead of paying full freight for dedicated staff plus tooling. Internal teams rarely beat an MSP on pure dollars until you reach a scale and a set of specialized, in-person, or control requirements that an outside team genuinely cannot own — at which point you are paying for dedication and control, not savings. See the full breakdown in our MSP pricing guide.
Side by side
Internal IT vs an MSP, head to head
Cost is only one row. Across the dimensions that actually determine whether your technology helps or hurts the business, the two models have very different strengths. This is the comparison that matters once you have normalized the dollars.
| Factor | Internal IT | Managed service provider |
|---|---|---|
| Cost (30-person org) | One loaded hire ~$110k–$175k/yr, limited coverage | ~$45k/yr fully managed, full team included |
| Coverage hours | Business hours; gaps during PTO, sickness, and turnover | 24/7 monitoring; no single-person coverage gaps |
| Expertise breadth | One or two generalists stretched across every domain | A bench of specialists: network, security, cloud, compliance |
| Scaling up | Recruit, hire, and train — weeks to months of lag | Add or remove seats in days |
| Security operations | A 24/7 SOC is hard and costly to staff in-house | EDR/MDR and SOC available as a service tier |
| Tooling | You buy and maintain RMM, PSA, and security tools | Enterprise tooling included in the per-user fee |
| Continuity risk | Single point of failure; knowledge can walk out the door | Redundant team with documented processes |
| Institutional knowledge | Deep, dedicated, and on-site | Less innate context; offset by strong documentation |
| In-person response | Immediate for physical and hands-on issues | Remote-first; on-site by scheduled dispatch |
| Strategic alignment | Fully dedicated to your goals | Shared across clients; guided by a vCIO cadence |
The pattern is consistent: an MSP wins on breadth, coverage, elasticity, and cost, while internal IT wins on dedication, context, control, and physical immediacy. Neither is “better” in the abstract — the right choice is the one whose strengths line up with what your business actually depends on.
The internal case
When internal IT is the right call
Building or keeping an in-house team makes sense when dedication, control, and physical presence outweigh the cost and breadth advantages of outsourcing. The signals below tend to point toward hiring.
- You are large enough to keep a team busy. Past roughly 75 to 100 employees, a small internal team can be fully utilized and the per-user economics of full outsourcing start to add up.
- Technology is your product or your core differentiator. Software firms, online platforms, and engineering-heavy companies usually need deep, dedicated, in-house ownership of their systems.
- You run complex, proprietary, or in-person systems. Manufacturing lines, labs, custom line-of-business apps, and frequent hands-on hardware needs reward staff who are physically present and know the environment cold.
- You require maximum control and immediate response. When minutes of downtime are costly and you want a named person accountable on-site, dedicated employees deliver that immediacy.
- Your environment is stable and predictable. Steady headcount and a settled tech stack make it easier to right-size a team and keep it efficient.
Even when these signals are strong, very few organizations staff a 24/7 security operations center entirely in-house — which is why most internal teams still pair with an MSP for security and after-hours coverage. That is the co-managed model, covered below.
The MSP case
When an MSP is the right call
Outsourcing makes sense when you need broad capability and reliable coverage without the cost and management overhead of building a team. These signals point toward an MSP.
- You are a small or mid-sized business. Under about 50 employees, an MSP almost always delivers more capability for less than the loaded cost of one or two internal hires.
- You need 24/7 coverage and real security operations. Round-the-clock monitoring, EDR/MDR, and a SOC are difficult and expensive to staff in-house but come standard in an MSP’s upper tiers.
- You are growing or changing fast. Adding seats in days beats a months-long hiring cycle when headcount is moving.
- You have compliance obligations. HIPAA, CMMC, SOC 2, or FINRA work benefits from specialists who do it every day across many clients.
- You want predictable budgeting. One per-user fee that includes tooling is easier to forecast than salaries, benefits, software licenses, and turnover.
- You cannot recruit or retain IT talent. In tight or rural labor markets, renting a team is often the only practical way to get senior expertise.
The third option
Co-managed IT: the best of both
Most mid-market companies do not choose one pole — they split the work. Co-managed IT keeps a lean internal team for the things that reward dedication and context, and hands the MSP the things that are hard, expensive, or impossible to staff around the clock. It typically runs $40 to $100 per user per month on top of your internal payroll, because the MSP is augmenting rather than replacing your team.
| Responsibility | Usually internal | Usually the MSP |
|---|---|---|
| Day-to-day helpdesk & floor support | Primary, in-person | Overflow and after-hours |
| Strategy, budgeting & vendor management | Internal IT lead / vCIO | Advisory and benchmarking |
| 24/7 monitoring & after-hours response | — | Owned by the MSP |
| Security operations (SOC, SIEM, MDR) | — | Owned by the MSP |
| Patching, RMM & tooling platform | Co-managed | MSP-provided platform |
| Projects, migrations & surge work | Co-managed | MSP bench depth |
| Line-of-business & institutional knowledge | Internal | — |
| Compliance documentation | Co-managed | MSP specialists |
Done well, co-managed IT gives you the dedication and context of employees plus the breadth, tooling, and 24/7 security of an MSP — usually for less than building all of those capabilities internally. The key is a clear division of responsibilities written into the agreement, so nothing falls through the cracks between the two teams.
By headcount
What’s usually right by company size
Headcount is the single best predictor of which model fits. These are general planning recommendations — your security, compliance, and in-person needs can shift the line — but they hold for most businesses.
| Company size | Usual best fit | Why |
|---|---|---|
| Under 20 employees | MSP (fully managed) | No way to justify or fully use a hire; an MSP team costs less than one salary |
| 20–50 employees | MSP, or MSP + first IT generalist | One internal hire cannot cover breadth or after-hours; the MSP supplies the team |
| 50–100 employees | Co-managed | An internal lead owns daily support and strategy; the MSP supplies depth and security |
| 100–250 employees | Co-managed or internal team + MSP security | Internal team handles the floor; MSP covers 24/7 SOC and project surge |
| 250+ employees | Internal department, often co-managed | Scale justifies a department; most still outsource the SOC and specialized work |
Notice that the recommendation is rarely “pure internal.” Even at enterprise scale, the 24/7 security layer is so hard to staff that co-managed remains the practical default. The transition is usually MSP first, then add an internal IT lead as you cross 50 to 75 employees, then grow that into a team while keeping the MSP for security and surge.
Make the call
Six questions that decide it
If the size guidance leaves you on the fence, work through these six questions. The answers point clearly toward internal, MSP, or co-managed for almost every business.
How much coverage do you need?
If you need after-hours or 24/7 support, one or two employees cannot provide it without burnout. That points to an MSP or co-managed coverage.
What are your security & compliance needs?
A real SOC and documented HIPAA, CMMC, or SOC 2 controls are hard to build in-house. MSP depth or co-managed security usually wins here.
How physical is your environment?
Labs, manufacturing floors, and frequent hands-on hardware work reward on-site staff. Heavy physical needs tilt toward internal presence.
How predictable is your budget?
If you value one forecastable number over managing salaries, benefits, and tooling, the MSP per-user model is easier to plan around.
What is your growth trajectory?
Fast or uneven growth favors the elasticity of an MSP; a stable, settled headcount makes an internal team easier to right-size.
How much control do you need?
Proprietary systems and a need for dedicated, on-site ownership point to internal staff — often kept alongside an MSP in a co-managed split.
Watch out
Decision red flags & common mistakes
Whichever way you lean, these are the patterns that reliably lead to regret — avoid them and the decision tends to age well.
- Expecting one hire to do everything. A single “IT person” cannot be a helpdesk, a security team, a strategist, and a 24/7 on-call resource at once. That expectation burns out good people and leaves gaps.
- Going internal purely to “save money.” If you do not count benefits, tooling, training, PTO coverage, and turnover, the in-house option looks cheaper than it is. Compare fully loaded costs.
- Choosing an MSP on the lowest per-user price. A cheap quote that omits EDR, MDR, MFA, and email security is not a deal. Normalize scope first — see the MSP pricing guide.
- Treating it as all-or-nothing. Many companies agonize over internal versus MSP when co-managed solves their actual problem — daily presence plus 24/7 security — better than either pole.
- Keeping no documentation. If everything lives in one employee’s head, that knowledge walks out the door when they leave. Require documented runbooks whether the team is internal or outsourced.
- Outsourcing without keeping the keys. Always own your Microsoft 365 and security tenants and hold your own admin credentials, so you can change providers without being held hostage.
Questions
MSP vs internal IT FAQs
For most small and mid-sized businesses, yes. Fully managed IT typically runs $75 to $200 per user per month in 2026, so a 30-person company pays roughly $45,000 a year and gets a whole team with 24/7 monitoring. The fully loaded cost of one internal mid-level hire — salary plus benefits, tooling, training, and recruiting — is often $110,000 to $175,000 a year and still only covers business hours.
Internal teams rarely beat an MSP on pure dollars until you reach a scale and a set of specialized or in-person requirements that an outside team cannot own. At that point you are paying for dedication and control, not for savings.
Internal IT is staff on your payroll who work only for you; you pay salaries, benefits, training, and tools. A managed service provider (MSP) is an outside firm that runs your IT for a recurring per-user or per-device fee, bringing its own team and tooling.
The practical difference is dedication versus breadth. Internal staff know your business deeply and are on-site, but cover only business hours and a limited skill set. An MSP supplies a bench of specialists, 24/7 coverage, and enterprise tooling, but with less innate context and a remote-first model.
As a rule of thumb, businesses under about 50 employees are usually best served by an MSP, because one or two internal hires cannot match a team’s breadth or coverage. Between 50 and 100 employees, most companies add an internal IT lead and move to a co-managed model. Past 100 to 250 employees, a full internal team becomes viable, though almost all keep an MSP for security operations and after-hours coverage.
Size is the best single predictor, but security, compliance, and in-person needs can move the line in either direction.
Co-managed IT is a hybrid where your internal staff and an MSP split responsibilities by design. The internal team typically owns day-to-day support, vendor relationships, and knowledge of your line-of-business systems, while the MSP supplies 24/7 monitoring, a security operations center, tooling, and surge capacity for projects.
It usually costs $40 to $100 per user per month on top of internal payroll, because the MSP is augmenting your team rather than replacing it. Co-managed is the default for mid-market companies that have outgrown a single model.
For most small and mid-sized businesses, yes — a fully managed MSP can own the entire IT function, from helpdesk and patching to security and strategy through a virtual CIO. Many companies under 50 employees run with no internal IT staff at all.
Larger organizations, or those with heavy in-person, proprietary, or control requirements, usually keep at least an internal IT lead and shift to a co-managed split rather than full replacement. The MSP still handles the hard-to-staff layers like 24/7 security, but an employee owns strategy and institutional knowledge.
Neither is universally better; it depends on fit. An MSP wins on cost, breadth of expertise, 24/7 coverage, and the ability to scale quickly. In-house IT wins on dedication, deep institutional knowledge, control, and immediate in-person response.
Match the model to what your business depends on. Smaller, fast-growing, or compliance-driven companies usually favor an MSP; larger, technology-centric, or hands-on operations lean internal; and a large share of mid-market firms get the best of both with a co-managed arrangement.
The main risks are less in-person immediacy, less innate knowledge of your business, and dependence on a vendor. You can manage all three. Insist on documented runbooks and response-time SLAs, keep ownership of your Microsoft 365 and security tenants and admin credentials, and confirm clear offboarding terms before you sign.
Choosing a provider with strong references and transparent scope removes most of the downside. Our guide on how to choose an MSP walks through the due diligence, and the Trust Score methodology explains how we evaluate providers independently.
Start by documenting your environment and defining the scope you want the MSP to own — full management, or a co-managed split where your team keeps daily support and the MSP takes security and after-hours. Expect a one-time onboarding period of a few weeks while the provider documents systems, deploys tooling, and remediates gaps, billed at one to three times the monthly rate.
If you have internal staff, redraw responsibilities in writing so nothing falls between the teams, and keep your tenants and credentials in your own name throughout. Then shortlist providers from our MSP rankings and compare quotes on equivalent scope.
