Sole proprietor or system house? Choosing an IT partner for SMEs
Should a sole proprietor handle your IT, or a system house? Both have their place. I am a sole proprietor myself, so here is an honest weighing-up rather than one-sided advertising, to help you make the right decision for your company.

Two models, one goal
Whether sole proprietor or system house, the goal is the same: IT that runs. Both can work to the modern managed service model, looking after IT continuously and proactively from a distance, usually for a fixed monthly fee. That provides predictable costs and contrasts with the classic break-fix approach, where things are only repaired and billed after an outage. The technical basis for it (remote monitoring, patch management) is independent of provider size.
The difference lies less in the what than in the how, and above all in the size and structure of the provider.
My perspective as a sole proprietor
I do not want to sell what I experience as advantages in practice as universal truth, but as what it is: my experience.
- One dedicated contact: you always talk to the person who does the work. No ticket ping-pong, no rotating account manager.
- Short distances: decisions are made quickly, without internal approval loops.
- Everything from one source: software and infrastructure from one person who knows how each affects the other, instead of several providers blaming each other.
- A lean cost structure: no large overhead, no expensive city-centre offices to pay for.
When a system house is the better choice
To be fair, the other side belongs here just as much. A system house can play to strengths a single person cannot offer:
- Scale: with very many sites, hundreds of workstations or parallel large projects, a team brings more capacity.
- Breadth and specialisation: several people cover more specialist areas at the same time.
- Cover and availability: with guaranteed round-the-clock response times and formal SLAs, a larger team has structural advantages.
The honest question about availability
The obvious objection with a sole proprietor is: what if they are out sick or on holiday? A fair question. What matters here is clean documentation, remotely manageable systems and clear agreements on availability. For critical requirements with hard 24/7 SLAs you should raise this openly and, in case of doubt, choose a model with guaranteed cover.
How to base the decision
- How critical is your IT, and what response times do you really need?
- How large and how distributed is your environment (workstations, sites)?
- Do you want a personal contact or an institutional structure with cover?
- How important is it to you that software and infrastructure come from one source?
For many small and medium businesses without their own IT team, the closeness and directness of a sole proprietor is exactly right. For others, a system house is the better choice. If you are unsure, in the initial call I will tell you honestly whether I am the right partner for you, even if the answer is sometimes no.

Frequently asked questions
Is a sole proprietor cheaper than a system house?+
There is no blanket answer. A sole proprietor often has a leaner cost structure, while a system house has more capacity. What matters is what you actually need. Blanket price promises would be dubious.
What happens if my sole proprietor is unavailable?+
That is the most important question. Remotely manageable, documented systems and clear agreements on availability help. For hard 24/7 requirements you should plan for guaranteed cover and clarify it up front.
Do both work to the same model?+
Often yes. Both small and large providers can work proactively to the managed service model with a fixed monthly fee, rather than only reactively on the break-fix principle.
Who is a sole proprietor particularly suitable for?+
Above all for small and medium businesses without their own IT department who value a direct, dedicated contact and short distances.
