Business IT Support

What people actually mean by “business IT support”

Most people start looking for IT support because something is broken and there is nobody obvious to call. By the time a business has a handful of staff, though, IT support has become a job with a lot in it that has nothing to do with fixing.

There is identity and access: who can log in, to what, and whether multi-factor authentication is switched on for everyone or only for the people who volunteered. There is email, which is the system a business can least afford to lose and the one most likely to be attacked. There is backup, and the harder question of whether anyone has ever tested a restore. There is licensing, which quietly bills you for people who left two years ago. There are new starters, who need a laptop, an account and the right file access on their first morning, and leavers, whose access needs to actually stop. There is buying kit that fits what you already run, then setting it up so it joins the estate rather than sitting outside it. And underneath all of it, security and patching.

Fixing broken things is the visible part. The rest is what decides how often things break.

The four ways businesses buy it

Almost every arrangement on the market is one of four shapes. They are not a ladder, and you are not failing if you are on the first rung. Each suits a different business, and each has a real downside.

Break-fix, or ad-hoc

You call when something goes wrong and you pay for the time it takes. No contract, no monthly fee, no commitment either way.

Right for you if you have a small team, everything you use is cloud-based, there is no server in a cupboard, and a day without a laptop would be annoying rather than expensive. Plenty of good small businesses run this way for years, and it is the honest answer for them. A small surgical instrument supplier we work with books an hour when they need an hour — that arrangement has run since December 2024 with no contract at all.

The downside is that nobody is minding the gaps. Nothing gets patched between calls. Nobody notices that the backup stopped running in March. You find out how bad a problem is only once it is already a problem, and the bill is largest in the months you can least afford it.

Managed

A fixed monthly fee covers proactive monitoring, patching and a helpdesk your staff contact directly. Somebody is looking at your systems whether or not you have called.

Right for you if the same faults keep coming back, your team loses real time to IT, or you have obligations — client security questionnaires, insurance, an audit — that need someone able to answer for how your systems are run. The fixed fee also flips the incentive: the provider does better when your systems stop breaking, rather than being paid by the hour to turn up. How managed support works day to day is worth reading if that sounds like you.

The downside is that you pay in the quiet months too, and scope matters enormously. A low monthly fee that excludes projects, hardware and anything labelled out-of-scope has not saved you money — it has moved the cost somewhere you meet it later.

Co-managed

You already employ someone who does IT, and a provider works alongside them rather than replacing them.

Right for you if your IT person is competent and knows the business, but is one person — holidays are risky, specialist work like tenant configuration or firewall changes comes round too rarely for them to stay sharp on it, and half the credentials live in one head. Co-managed support covers absence, escalation, and the projects that will not fit into one person’s week.

The downside is that it only works when the split is written down. Two teams with a vague boundary is worse than one team with a clear one — the jobs that fall between them are the ones nobody picks up.

Fully outsourced

The whole IT function, including strategy, budgeting and dealing with your suppliers — not just keeping the kit alive, but deciding what the kit should be.

Right for you if you are large enough to need IT decisions made deliberately, and not large enough to justify an IT manager on the payroll. Full outsourcing covers that decision, and the handover, in more detail than there is room for here.

The downside is dependency. You are trusting one organisation with the knowledge of how your business runs, so documentation and access transparency stop being nice-to-haves. Ask how you would leave, before you sign.

Remote or on-site is a separate question

The four models describe the commercial arrangement. Delivery cuts across all of them.

Most day-to-day faults are software, accounts or configuration, and remote support handles those without anyone travelling. Hardware failures, cabling, switches and access points, office moves, and any machine that will not power on need somebody physically present — that is what on-site work is for. A remote-only provider will eventually leave you stuck with a dead machine. One who sends an engineer for a password reset is spending your money for you. You want both.

Signs you have outgrown what you have

These are the ones we hear most:

• The same fault keeps coming back and nobody has looked at why
• Nobody in the business knows the admin password for something important
• Someone who left months ago still has an active account or a live mailbox
• There is a backup, but nobody has ever restored from it to check it works
• One person is the only one who understands how anything is set up
• A client has sent you a security questionnaire and you do not know the answers

Any one of these is worth fixing. Two or three together usually means the arrangement stopped fitting a while ago and nobody had time to notice.

What changes as you grow

At around five people, IT is a handful of laptops and a Microsoft 365 or Google Workspace tenant. Almost any arrangement works. The main risk is that nothing is written down, so the business is one lost password from a bad week.

By twenty, the picture changes. Starters and leavers become routine, so a repeatable process is worth more than any individual fix. File permissions start to matter, because not everyone should see everything. Somebody is asking about your security posture, usually a client rather than an auditor. The cost of an outage is now measured in a room full of idle people rather than one desk.

By fifty, you have shape: departments, line-of-business software, probably a server or a network that deserves the name, and enough devices that patching by hand stops being realistic. This is where most businesses either hire internally and back that person with co-managed support, or hand the function over entirely. Doing neither is what produces the tangle we most often get called in to unpick.

Judging a provider when you cannot judge the answers

Nearly everyone shopping for IT support is buying something they cannot personally evaluate. Some questions work anyway, because they test behaviour rather than technical knowledge.

Ask what is not included, and listen for whether the answer is specific or waffly. Ask who actually does the work — the people in the room, or somebody you will never meet. Ask them to explain something technical they have just said; a provider who cannot explain their own work in plain English will not explain it to your staff either. And ask what they would look at first, before selling you anything — anyone quoting a monthly figure without seeing what you run is guessing. Our guide on choosing an IT support company works through this properly.

Where we work

We are based in SW16 and work on-site across South London, Croydon and into Surrey, with remote support wherever your people are — which increasingly means an office in one place and staff at home in others. The areas we cover page lists the towns we reach. If you are not sure which of these four fits, that is a fair thing to want a conversation about.
