Growing Your Business? An IT Roadmap From 5 to 50 Staff

The IT that works for five people usually starts to creak at fifteen and becomes a genuine business risk at thirty. Shared passwords, a mix of personal and work accounts, laptops bought one at a time and a “tech-savvy” staff member fixing things between real work all hold up for a while. Then one day they do not.

This roadmap sets out what a growing small business should put in place at each stage, so technology keeps pace with the business instead of holding it back.

Stage 1: 1 to 10 staff, get the foundations right

At this size the goal is simple: every person has their own secure account, and nothing important lives on one person’s laptop.

• Business email and files in Microsoft 365 or Google Workspace, on your own domain, not free personal accounts.
• Multi-factor authentication on every account, starting with email and banking.
• A password manager for shared logins, instead of spreadsheets or sticky notes.
• Backups of email and files, separate from Microsoft or Google.
• A record of who owns what: domain name, website hosting, software subscriptions and admin logins, all in the business’s name.

Mistakes made here are cheap to fix now and expensive later. The most common one we see is a domain or Microsoft 365 tenancy registered to a former staff member or web developer.

Stage 2: 10 to 20 staff, standardise

This is where ad-hoc IT starts costing real time. New starters wait days for a laptop, nobody is sure which software licences are in use, and the person “who does the IT” is losing hours from their actual job.

• Standard devices bought from business ranges with warranty, set up the same way every time.
• Device management (such as Microsoft Intune) so laptops and phones can be configured, updated and wiped remotely.
• Onboarding and offboarding checklists so access is granted and removed properly.
• Organised file structure in SharePoint or shared drives, with permissions by team rather than by person.
• A helpdesk staff can call or email, so problems are logged and fixed properly.

Most businesses move from break-fix support to managed IT around this point, because the cost of interruptions overtakes the cost of a fixed monthly fee.

Stage 3: 20 to 35 staff, secure and document

With more people, more devices and more client data, the business becomes a more attractive target, and customers start asking security questions in tenders and supplier forms.

• An Essential Eight baseline: patching, application control, restricted admin rights, MFA and tested backups. Our Essential Eight guide explains each control.
• Email security: SPF, DKIM and DMARC on your domain, plus filtering to stop phishing and invoice fraud.
• Security awareness training and simulated phishing for staff.
• Written policies: acceptable use, AI use, remote work and incident response, kept short and practical.
• Cyber insurance reviewed against the controls you actually have. See what cyber policies really cover.

Stage 4: 35 to 50+ staff, plan and measure

At this size IT should be planned like any other part of the business, with a budget, a roadmap and regular reporting.

• A 12 to 36 month IT roadmap covering device replacement, software changes and security improvements, with costs ex GST so they can be budgeted.
• Quarterly reviews with your IT provider covering tickets, risks, upcoming renewals and projects.
• Business continuity planning: how long you can be without each system, and how you would recover.
• Multiple sites or remote teams connected securely, with consistent standards everywhere.
• Automation of repetitive admin using tools you already pay for, such as Power Automate or Copilot. See how to use AI to automate everyday tasks.

Signs your IT is already behind your growth

• New starters cannot work on day one.
• The same problems keep coming back.
• Nobody can say quickly which staff have access to what.
• A key system depends on one person’s knowledge or login.
• You are not sure your backups would work.
• Clients or insurers are asking security questions you cannot answer.

If several of these sound familiar, read key signs your business needs a reliable IT partner.

What it costs

For most growing businesses, fully managed IT in Sydney sits between $100 and $250 per user, per month, ex GST, depending on what is included. Our managed IT pricing guide explains what drives the difference and how to compare quotes.
