How Much Should a Small Business Spend on IT?
"How much should we spend on IT?" is one of the most common questions small businesses ask us — usually right after something has gone expensively wrong. There's no single magic percentage, whatever the industry surveys claim. But there are sensible, practical ways to think about IT spend so it supports the business, stays predictable, and stops being a series of unpleasant surprises. Here's the framework we walk our own clients through.
Move from break-fix to planned spend
Many small businesses only spend on IT when something breaks. It feels cheaper — no monthly cost, pay only when needed — but it's a false economy three times over: emergency call-outs cost more than planned work, problems are only ever fixed after they've already stopped someone working, and nothing is ever done to prevent the next failure. Treating IT as a planned, ongoing cost — like rent, insurance or the accountant — flips that. Budgeting becomes straightforward, downtime becomes rare, and the money shifts from firefighting to prevention, which is where it earns its keep.
What a complete IT budget covers
- Hardware — computers and equipment replaced on a sensible three-to-five-year cycle rather than run until they fail at the worst moment. Spreading replacements across the year (a few machines per quarter) turns a painful lump into a steady, plannable cost.
- Software and subscriptions — email, productivity tools, line-of-business apps and licences, reviewed yearly so you're not quietly paying for seats nobody uses. Most businesses we audit find at least one forgotten subscription.
- Security — protection, backups and staff awareness training. Always dramatically cheaper than the ransomware incident or fraud loss it prevents.
- Support — someone to call when things go wrong, and to keep things maintained so they go wrong less often.
- A small contingency — because something unexpected happens every year, and a budget with no slack becomes a crisis budget.
A simple way to size it
Rather than chasing an industry percentage, start from what your business actually depends on. Count your devices and users. List the systems you'd genuinely struggle without — email, accounts, the job-management system, the till. Then ask the clarifying question: "what would it cost us if this stopped for a day?" Lost billable hours, missed orders, staff paid to wait, customers let down. That number — not a survey average — tells you where protection money is well spent and where a cheaper option is fine. A business that would lose four figures in a down day should not be protecting itself with a three-figure annual budget.
The real cost is downtime
The visible IT costs — kit, licences, support — are easy to see on an invoice. The invisible one is downtime, and it's almost always bigger: when systems are down, staff can't work, customers can't be served, and the costs mount quietly by the hour with nothing to show for them. Spending modestly on prevention — monitored backups, maintenance, updates, decent hardware — almost always costs less than the disruption it avoids. It's the IT equivalent of servicing the van rather than waiting for it to die on the motorway with a full load.
Watch the hidden money-leaks
Two budget-killers hide in plain sight. The first is too-old equipment: a slow machine quietly taxes its user every single day — minutes lost per hour add up to real money that never appears on any IT invoice (an SSD upgrade is often the cheapest fix). The second is the DIY IT person: when the office manager spends hours each week resetting passwords and fixing the printer, you're paying a salary for work that isn't theirs — one of the classic signs a business has outgrown DIY IT.
Review it once a year — briefly
An IT budget isn't a one-off exercise; businesses change, and last year's sensible plan quietly drifts. Once a year — perhaps alongside your accounts — spend an hour on four questions: What did IT actually cost us, including the emergencies? What subscriptions and licences are we paying for that nobody uses? Which machines will pass the sensible replacement age next year? And has anything changed — new staff, new premises, new software — that shifts what we depend on? That single hour keeps the budget honest, catches the money-leaks early, and turns next year's spending from guesswork into a plan.
Predictable IT, predictable cost
This is exactly the problem managed IT services exist to solve: support, monitoring, security and maintenance wrapped into a fixed monthly fee, so your IT spend is known in advance with no surprise bills — and your provider's incentive is keeping things running, not billing for breakdowns. Backed by our business IT support when you need extra hands, it turns the whole question of "how much should we spend?" into a number you can actually plan around.
