Your own IT hire or an external provider?

An in-house IT hire, an external provider, or a hybrid of the two — these are the three options businesses choose between once IT support outgrows something the owner can handle on the side. An in-house hire knows the business, its grown systems and the people involved firsthand, and is available without scheduling ahead. An external provider brings a team with a spread of specialisations and isn't tied to a single person.

A hybrid combines both: an internal contact who knows the business, handles day-to-day issues and talks to staff, and an external team that brings the depth and breadth of expertise a single person can rarely build up alone. In mid-sized businesses with a grown IT landscape, that combination is the most common answer in practice.

A single-person model has a structural problem that has nothing to do with how skilled that person is: if they're out, IT support is out with them. Vacation can be planned around; illness can't — and it's often exactly then that the firewall glitches or a server hangs. Without cover, the business is left without a technical contact for that entire period.

A resignation is worse still. The knowledge behind grown, custom setups, specific configurations and the reasoning behind past decisions often leaves with the person — unless it was written down somewhere. An external provider doesn't remove this risk automatically, but a team spreads that knowledge across several people, so one person being unavailable doesn't stop the whole business.

Network design, firewall configuration, server operations, video surveillance and support for the specialist software in use are five distinct fields that rarely bundle fully into one person in practice. Someone strong in firewalls doesn't automatically have the same depth in server infrastructure or camera systems — each field develops independently and demands its own ongoing training.

Then there's the question of who responds outside office hours. A server failure on a weekend or a security incident in the evening doesn't wait for the next business day. A single person can't be on call around the clock without it wearing them down over time — a team can spread on-call duty so it doesn't fall on one person every time.

Good documentation decides whether cover can actually act in an emergency — regardless of whether IT is handled in-house or externally. Network diagrams, credentials, configurations and the reasoning behind custom setups belong in writing, not only in one person's head. Where that documentation is missing, every staff change becomes a risk that only shows up once something breaks.

Procurement and vendor contact also work differently between the two: an in-house hire usually orders through the business's existing supplier relationships, while a provider often brings its own purchasing channels and direct vendor contacts. Bigger projects — a new server environment or a business-wide network overhaul — also need a clear escalation point: a person or team that can actually make decisions when there are delays or technical conflicts, rather than responsibility bouncing between internal and external parties.
