Most Australian small businesses land in one of two camps when it comes to technology spending. The first camp underspends: they run five-year-old laptops, skip security tools, and only call for help when something is already on fire. The second camp overspends: they're paying for overlapping software subscriptions, unused licences, and premium tools nobody on the team actually opens.
Both camps have the same underlying problem — they don't know what a reasonable IT spend looks like for a business their size. This guide answers that question with real benchmarks, then shows you where the money should actually go.
If you're after the step-by-step process of building the budget document itself — categories, review cycles, who to involve — we've covered that separately in our guide on how to create an IT budget for a small business. This article focuses on the numbers: how much, and on what.
How Much Do Australian Small Businesses Actually Spend on IT?
The most useful benchmark is IT spend as a percentage of annual revenue. Across most industries, small businesses typically spend somewhere between 3% and 7% of revenue on technology. Where you sit inside that range depends heavily on how dependent your business is on IT to earn money.
| Industry | Typical IT Spend (% of Revenue) | Why |
|---|---|---|
| Professional services (accounting, legal, consulting) | 4–7% | Staff are fully dependent on systems and client data; downtime directly stops billable work |
| Allied health & medical | 4–6% | Practice management software, compliance obligations, and sensitive patient data under the Privacy Act |
| Construction & trades | 2–4% | Lower desk-based dependency, but growing spend on job management and field apps |
| Retail & hospitality | 2–4% | POS, payments, and inventory systems — critical but relatively contained |
| eCommerce & online-first businesses | 6–10%+ | The website is the business; hosting, development, and security are core operating costs |
Another way to sanity-check your budget is spend per employee. For an Australian SMB with 5–50 staff, a healthy all-in figure — support, software, security, hardware refresh, and internet — usually lands between $2,500 and $5,000 per employee per year. If you're a 15-person professional services firm spending $12,000 a year in total, you're almost certainly underspending somewhere that will eventually cost you far more.
The underspending trap: A budget that looks lean on paper often isn't. Businesses that skimp on IT still pay for it — in staff hours lost to slow machines, emergency call-out fees, and recovery costs after an incident. The ACSC puts the average cost of a cybercrime incident for an Australian small business at around $50,000. One incident can wipe out a decade of “savings” from a skinny security budget.
Where Should the Money Go? A Practical Allocation
Knowing the total is only half the job. The bigger mistake we see isn't the size of the budget — it's the shape of it. Businesses spend heavily on shiny software while running no tested backups, or buy top-shelf laptops while their website quietly loses them customers.
For a typical 5–50 person Australian business, a well-balanced IT budget roughly breaks down like this:
| Category | Share of IT Budget | What It Covers |
|---|---|---|
| IT support & management | 30–40% | Managed IT services or internal support, monitoring, patching, help desk |
| Software & cloud subscriptions | 20–30% | Microsoft 365, line-of-business apps, accounting software, licencing |
| Cybersecurity | 10–15% | EDR, email security, MFA, backups, security awareness training |
| Hardware refresh | 10–15% | Laptops, monitors, networking gear — replaced on a planned cycle, not when they die |
| Website & digital presence | 5–15% | Website hosting, maintenance, care plans, SEO, and periodic rebuilds |
| Contingency | 5–10% | Unplanned failures, urgent replacements, mid-year staff growth |
A few notes on the categories most businesses get wrong:
Support: predictable beats reactive
If your support spend is entirely ad-hoc hourly billing, your budget is a guess. Fixed-fee managed support makes this line item predictable and shifts the incentive toward preventing problems rather than billing for them. We've broken down typical Australian pricing in how much IT support costs for a small business in Australia — as a quick reference, expect $80–$200 per user per month depending on scope.
Software: audit before you add
Subscription creep is the single biggest source of IT waste in small businesses. Duplicate tools, licences for staff who left months ago, premium tiers nobody uses. Before budgeting for anything new, audit what you already pay for — many businesses discover their Microsoft 365 plan already includes tools they're paying for separately elsewhere. Our guide to Microsoft 365 pricing in Australia covers what each plan actually includes.
Hardware: budget the refresh cycle, not the emergency
A business laptop has a sensible working life of 3–4 years. Divide your fleet by that number and you know how many devices to budget for each year. A 20-person business should expect to replace 5–7 devices annually at roughly $1,500–$2,500 each. Budgeting this way is dramatically cheaper than the alternative: a critical machine dying mid-project and an urgent retail-price replacement. The instant asset write-off rules also make planned hardware purchases more tax-efficient — worth a conversation with your accountant before end of financial year.
Website: it's an IT cost, not a marketing afterthought
Your website is business infrastructure. It needs hosting, security updates, backups, and performance maintenance the same way your laptops do — yet it's missing from most SMB IT budgets entirely. Budget for both the ongoing care (a website care plan typically runs $99–$300/month) and a rebuild roughly every 4–5 years as design standards and performance expectations move on.
The Costs Most Small Businesses Forget
When we review IT budgets for new clients, the same blind spots come up again and again:
- Backup and recovery. Microsoft 365 does not fully back up your data by default — a fact that surprises most business owners. Proper backup for email, SharePoint, and OneDrive is a separate (and modest) line item.
- Staff onboarding and offboarding. Every new hire needs a device, licences, and account setup — typically $2,000–$3,500 in first-year IT cost per person. If you're planning to hire, your IT budget needs to know.
- Licence renewals and price rises. Software vendors raise prices almost every year. Budget a 5–10% increase on subscriptions rather than copying last year's number.
- Security awareness training. Most breaches start with a person, not a firewall. A small annual spend on phishing training delivers outsized risk reduction.
- Cyber insurance. Increasingly expected by larger clients and partners — and insurers now demand evidence of basic controls like MFA before they'll pay a claim.
- Warranty and asset tracking. Knowing what you own, when warranties expire, and when licences renew prevents both surprise costs and paying for gear you no longer use.

Percentages and benchmarks are useful, but your own environment tells you the truth. Here's how each failure mode shows up in practice.
Signs you're underspending
- Staff regularly complain about slow computers, dropped connections, or recurring glitches
- You have no idea whether your backups work, because nobody has ever tested a restore
- Devices are older than four years and get replaced only when they fail
- There's no MFA on email or key business systems
- Every IT cost feels like a surprise, because nothing is planned
Signs you're overspending
- You can't list your software subscriptions from memory — and neither can anyone else
- You're paying for licences assigned to people who left the business
- Two or more tools do the same job (three chat apps, two file-sharing platforms)
- You bought premium tiers “to be safe” but use only the basic features
- Nobody reviews the IT spend annually against what the business actually needs
Interestingly, the fix for both problems is the same: someone needs to own the IT budget strategically, not just pay the invoices. In larger companies that's a CIO. For an SMB, that role is usually filled by your managed IT provider through a virtual CIO arrangement — someone who reviews spend, plans refresh cycles, and aligns technology decisions with where the business is heading.
A Worked Example: 15-Person Professional Services Firm
To make this concrete, here's what a sensible annual IT budget looks like for a 15-person Sydney-based firm turning over roughly $2.5 million:
- Managed IT support (15 users × $130/month): $23,400
- Microsoft 365 Business Premium (15 × ~$35/month): $6,300
- Line-of-business software (practice management, accounting): $8,000
- Security extras (M365 backup, awareness training, dark web monitoring): $3,000
- Hardware refresh (4–5 laptops/year at ~$2,000): $9,000
- Website care plan & SEO: $2,400–$5,000
- Internet & connectivity: $2,400
- Contingency (~8%): $4,500
That's roughly $59,000–$62,000 per year — about 2.4% of revenue, or around $4,000 per employee. Comfortably within benchmark, entirely predictable, and covering every category that matters: support, security, hardware, and digital presence. Compare that to the alternative of running lean until a ransomware incident or a dead server forces an unbudgeted five-figure recovery bill in a single week.
The Bottom Line
There's no single magic number for IT spending, but there are clear guardrails: 3–7% of revenue for most industries, or $2,500–$5,000 per employee per year for a business of 5–50 staff. More important than the total is the shape — a balanced spread across support, software, security, hardware, and your website, with a contingency buffer for the things you can't predict.
The businesses that get IT budgeting right aren't the ones that spend the most. They're the ones that spend deliberately — reviewing annually, auditing subscriptions, planning refresh cycles, and treating technology as the business infrastructure it is. If you'd like help getting there, our managed IT services include exactly this kind of budget planning as standard, and we're always happy to start with a free look at where you stand today.
