Perth business owners often use these terms interchangeably, but they describe two genuinely different ways of buying IT services, with different pricing models, different response patterns, and very different outcomes when something goes wrong. Here's a plain-English breakdown of both, what they actually cost, and how to tell which one fits your business.
Ad-Hoc IT Support
You call when something breaks. The provider fixes it. You pay for the time spent, usually $130 to $220 an hour in Perth.
- →Pay per incident or hour
- →Reactive - you report the problem
- →No ongoing monitoring
- →Variable monthly costs
- →Best for: very small businesses with minimal IT
Managed IT Services
A fixed monthly fee, typically $99 to $250 per user, covers monitoring, maintenance, helpdesk, and strategy.
- Fixed monthly cost
- Proactive - we spot issues before you do
- 24/7 monitoring included
- Predictable budget
- Best for: businesses that depend on IT to operate
The Key Difference: Reactive vs Proactive
With ad-hoc support, your IT provider only hears from you after something has already gone wrong. By then, you've usually already lost time, and possibly data. There's also no one watching your backups, patching your servers overnight, or noticing that a hard drive is throwing early warning errors before it fails completely.
With managed IT, monitoring agents installed on your servers, PCs, and network devices feed alerts to your provider continuously. A server running low on disk space, a failed backup job, a security patch that hasn't applied, or unusual login activity all get flagged and actioned, often before your staff notice anything different. The provider isn't waiting for the phone to ring.
Think of it like car servicing. Break-fix IT is like only taking your car to the mechanic when it breaks down on the side of the road, you pay more in the long run through emergency call-outs, towing, and consequential damage. Managed IT is like having regular scheduled services, it costs more upfront but consistently prevents the expensive breakdowns from happening at all.
What's Actually Included in a Managed IT Agreement
Managed IT agreements vary between providers, but a properly scoped one for a Perth SMB typically covers:
- Unlimited remote and on-site helpdesk support during business hours
- 24/7 monitoring of servers, workstations, and network equipment with automated alerting
- Patch management for operating systems and common applications
- Backup monitoring, with regular test restores to confirm backups actually work
- Endpoint security (antivirus/EDR) deployment and monitoring across all devices
- A documented IT environment, so you're not locked into one provider's institutional knowledge
- Quarterly or biannual strategy reviews covering upcoming hardware refreshes, licensing renewals, and security gaps
Ad-hoc support typically covers none of this. You're paying for a technician's time to resolve a specific issue when it's reported, not for ongoing oversight of your environment. That's not a criticism of ad-hoc providers, it's simply what the model is designed to deliver.
The Real Cost Comparison
On paper, ad-hoc support looks cheaper because you're only paying when there's a problem. In practice, the businesses we see come from ad-hoc arrangements to managed IT almost always discover they were losing more in staff downtime, emergency call-out premiums, and repeat issues than a flat monthly fee would have cost. One serious incident, a ransomware attack with no tested backup, or a server failure with no monitoring to catch the early warning signs, can easily cost more than a year of managed IT fees in lost revenue and recovery costs alone.
Which is right for your Perth business?
Choose ad-hoc if…
- You have fewer than 5 staff
- IT issues are genuinely rare (less than once a month)
- You have someone tech-savvy in-house for day-to-day issues
- Your budget can't yet support a monthly commitment
Choose managed IT if…
- Your team relies on computers and internet to operate
- You've experienced downtime that cost you money
- You don't have IT expertise in-house
- You want predictable monthly IT costs
- You handle sensitive client data or have compliance requirements
A Hybrid Middle Ground
Some Perth businesses land on a middle path, co-managed IT, where an in-house IT person or part-time contractor handles day-to-day requests, while a managed provider supplies the monitoring, security tooling, and after-hours coverage that's hard to staff internally. This works well for businesses that have outgrown ad-hoc support but aren't ready to outsource IT entirely.
Frequently Asked Questions
How much does managed IT cost for a small Perth business?
Most Perth managed IT providers price per user or per device per month, typically somewhere between $99 and $250 per user per month depending on what's included (helpdesk hours, on-site visits, security tooling, backup management). A 10-person office might land somewhere between $1,500 and $3,000 a month all-in. Ad-hoc support is usually billed at an hourly rate, commonly $130 to $220 per hour in Perth, plus call-out fees for on-site work.
Can I switch from ad-hoc support to managed IT later?
Yes, and it's a common transition as businesses grow. The main upfront step is an onboarding audit, where the new provider documents your systems, sets up monitoring agents on devices, and fixes any existing problems before billing starts properly. Most providers can complete onboarding within one to two weeks without disrupting day-to-day operations.
Does managed IT include hardware and software costs?
Generally no - managed IT covers the service of monitoring, maintaining, and supporting your systems, not the underlying hardware or software licences themselves. Most providers will procure and manage hardware and licensing on your behalf as part of the service, but those costs are billed separately or passed through, not bundled into the flat monthly fee.
What happens if something breaks outside business hours under managed IT?
This depends on the service level agreement (SLA) in your contract. Most Perth managed IT agreements include after-hours monitoring with alerting for critical issues like server outages or security incidents, even if the helpdesk itself operates standard business hours. If 24/7 response matters to your business, confirm it explicitly in the SLA rather than assuming it's included.
