The comparison is usually framed as cost, and cost is the least interesting part of it. Both models can be made to look cheaper depending on what you include, and the businesses that choose badly rarely do so because they got the arithmetic wrong.
They choose badly because they compared a salary against a monthly fee, which are not the same kind of thing.
What an internal IT hire actually costs
Start with the fully loaded figure rather than the salary. In the New York and Connecticut market, a competent generalist IT administrator — someone who can handle helpdesk, basic networking, Microsoft 365 administration and hardware — sits in a broad band, and the salary is roughly two-thirds of the real number.
Add to base salary:
- Payroll taxes and benefits, typically 30–45% on top
- Recruitment cost, whether agency fees or your own time
- Tooling that an MSP amortises across clients: RMM, ticketing, documentation, backup and security platforms, all of which carry minimum seat counts that a single admin makes expensive per head
- Training and certification to keep skills current
- The cost of coverage during holiday, illness and vacancy
The tooling line is the one most often missed. A managed provider spreads a security and management stack across hundreds of endpoints. A single internal admin either pays small-business pricing for the same tools, or — far more commonly — goes without them, which is the hidden cost that surfaces later.
The coverage problem nobody plans for
One person cannot cover a business. This sounds obvious and is routinely ignored.
A single internal administrator provides roughly 40 hours of availability across a week that has 168 hours in it. They take holiday. They get sick. They attend meetings. And critically, they cannot simultaneously work a project and answer the helpdesk — which means every migration, office move, or security rollout stops ticket response for its duration, or the project never finishes.
This is the structural failure of the single-admin model, and it has nothing to do with the quality of the person. It is arithmetic.
The depth problem
Modern business IT spans network engineering, cloud architecture, identity management, endpoint security, compliance, backup and disaster recovery, and vendor management. No individual is genuinely strong across all of it.
A good generalist covers most day-to-day work well and hits a ceiling on the specialist tasks — which are usually the high-stakes ones. Firewall configuration, tenant security hardening, a migration with no rollback window. That is where a bench matters.
Where outsourcing genuinely fails
The honest version of this comparison includes the cases where an internal hire is the better answer.
- Deep line-of-business knowledge. If your business runs on specialised software that requires real institutional understanding, an internal person who learns it properly will beat a generalist provider.
- Physical presence. Manufacturing, labs, healthcare with on-site equipment, anywhere hands are needed frequently rather than occasionally.
- Scale. Past roughly 150–250 seats, an internal team usually becomes cost-effective, and the calculation inverts.
- Culture and immediacy. Someone in the building who knows everyone's name provides something a ticket queue does not, and for some businesses that matters more than the SLA.
- Confidentiality. Some organisations have genuine reasons to keep systems access internal.
Outsourcing also fails when it is bought as a way to stop thinking about IT altogether. A provider needs a decision-maker on your side. Businesses that fully disengage get technically adequate service and strategically drifting environments.
The option most businesses should consider
Co-managed IT is consistently under-considered, and it fits the situation many businesses are actually in: one capable internal person who is overloaded, unsupported, and a single point of failure.
In a co-managed arrangement the internal person keeps what they are best at — user relationships, business context, day-to-day responsiveness — and the provider supplies what one person cannot: after-hours coverage, holiday cover, specialist depth, enterprise tooling, and a second opinion on architecture.
It is usually cheaper than a second hire and resolves the key-person risk that keeps owners awake, without discarding institutional knowledge that took years to build.
| Factor | Single in-house admin | Outsourced | Co-managed |
|---|---|---|---|
| Coverage | About 40 of 168 weekly hours; gaps for holiday and illness | Provider team covers | Provider covers after-hours and holidays |
| Specialist depth | Good generalist; ceiling on specialist work | A bench to draw on | Provider supplies specialist depth |
| Tooling | Small-business pricing, or goes without | Stack amortised across clients | Enterprise tooling from the provider |
| Business knowledge | Strong institutional and line-of-business knowledge | Generalist provider | Kept in-house |
| Physical presence | Always on site | Occasional, scheduled | Internal person on site |
| Key-person risk | High | Low | Resolved |
How to decide
Three questions settle most cases.
- How many hours per week does IT actually consume today? Under 20, an internal hire is hard to justify. Consistently over 40, one person is already insufficient.
- Does the work require someone physically present regularly, or occasionally? Occasionally is a scheduling problem. Regularly is a hiring problem.
- What happens if the person who handles IT is unavailable for two weeks? If the honest answer is that things gradually stop working, that risk needs addressing regardless of which model you choose.
Most businesses under 100 employees land on outsourced or co-managed, not because it is cheaper but because coverage and depth are structurally difficult to buy in a single hire. The businesses that succeed with internal IT usually have a specific reason — physical presence, specialised software, or scale — rather than a general preference.
