At some point, most growing businesses hit the same fork in the road. The IT has become too much to handle off the side of someone's desk, and the question lands: do we hire someone to look after it, or do we bring in a company to do it for us? It is a genuinely important decision, and I want to give you an honest way to think about it, including the parts that are not in my interest to mention. After twenty-two years on the provider side of this conversation, I have seen both choices work and both choices go wrong, and the difference is almost always in how the decision was made rather than which way it went.
So let me lay out the real trade-offs, not the sales-deck version.
The hidden cost of one internal hire
The instinctive sum people do is this: a managed provider quotes a monthly fee, an IT person costs a salary, compare the two. It feels tidy, and it is almost always wrong, because the salary is only the visible part of what an internal hire actually costs.
Add it up properly. On top of the salary there is the cost of recruiting them, the tools and software they need to do the job, their ongoing training to stay current in a field that changes every month, the management time to look after them, and the cover for when they are on leave or off sick. A single IT hire is meaningfully more expensive than their salary line suggests, and the gap is wide enough to change the answer. When people compare a provider's all-in monthly fee against a bare salary, they are not comparing like with like at all.
The risk nobody costs in: key-person dependency
Here is the bigger problem, and it is one I have watched bite good businesses hard. When all of your IT knowledge lives in one person's head, that person becomes a single point of failure for the entire company. They know where everything is, how it all connects, and what the passwords are. And then they take a holiday, or they get sick, or they hand in their notice, and suddenly nobody can do the things only they knew how to do.
This is not a knock on internal IT people, who are often excellent. It is just the nature of one of anything. One person cannot be on call around the clock, cannot be expert in every specialism a modern business needs, from networking to cloud to cyber security, and cannot be in two places at once when something breaks while they are already busy. The strength of an individual is also their fragility, and most businesses do not see that risk until the day it arrives.
When in-house genuinely makes sense
I am not going to pretend in-house is always the wrong call, because it is not. There are businesses where a dedicated internal person is exactly right. If you are large enough to keep a whole team properly busy and resourced, if your technology is so specialised or so central to what you sell that you need it owned in the building, or if you simply want someone on-site every day who lives and breathes your particular setup, then in-house can be the better answer.
The honest test is scale and specialism. A single hire struggles to cover the full breadth a business needs and carries that key-person risk. A proper internal team, several people deep, solves both of those, but it is a serious investment that only makes sense once you are big enough to justify and sustain it. Below that line, one hire is usually trying to do the job of five, and that is where it strains.
When a managed provider wins
For most small and medium businesses, a managed provider simply gives you more for the money, and the reason is breadth. Instead of one person and their one set of skills, you get a whole team and every specialism in it, for a predictable monthly fee that is often less than a single salary once you have counted the true cost of that salary. There is always someone available, holidays and sick days are somebody else's problem to cover, and the deep expertise across security, cloud, networking and the rest is there when you need it without you having to hire and retain all of it yourself.
You also get the things a single hire structurally cannot provide on their own: round-the-clock coverage, a documented setup that does not vanish when one person does, and the buying power and tooling of a larger operation. If you want the full side-by-side, we have written it out in detail on our managed IT versus in-house comparison, which walks through the costs and trade-offs without the spin.
The middle ground most people miss: co-managed
Here is the option that gets forgotten, and it is often the best of the lot. It is not actually a choice between your person and our company. You can have both. Co-managed IT means your internal person, or small team, keeps doing the on-the-ground, knows-the-business work they are good at, and a provider sits behind them with the broader expertise, the after-hours cover, the security depth and the backup for when they are away or out of their depth.
This solves the two big problems at once. Your internal person is no longer a single point of failure, because there is a whole team behind them, and they are no longer expected to be expert in everything, because the specialist work has somewhere to go. They get to focus on what they enjoy and do well, and you get the breadth and resilience of a provider on top. For a lot of growing businesses, this is the sweet spot, and it is worth understanding properly before you decide. We have laid out how it works on our co-managed versus fully managed page.
The strength of one brilliant IT person is also their fragility. One person cannot be on call around the clock, expert in everything, and in two places at once.
The simple version: compare the true cost of a hire, not just the salary, and take the key-person risk seriously. In-house wins when you are big enough for a real team. A managed provider wins on breadth and resilience for most businesses. And if you already have a good internal person, co-managed often beats both. If you want help working out which line your business actually sits on, that is a conversation we are glad to have, with no obligation at the end of it.
