For most Australian small businesses, the choice comes down to three Microsoft 365 plans: Business Basic for web-only teams, Business Standard for teams who want the desktop Office apps, and Business Premium for those who need stronger security and device controls. Standard is where the majority land. The harder part is not the plan, it is setting the thing up properly.
Microsoft 365 is sold per user per month, billed annually or monthly, and the tiers stack neatly: each one is the one below it plus a bit more. So the real question is not “which is best” but “where do we stop spending”. Here is how the ladder works.
The three business plans, plainly
Business Basic is the entry point. You get business email through Exchange, the web and mobile versions of Word, Excel, Outlook and PowerPoint, plus Teams, OneDrive and SharePoint. What you do not get is the full desktop apps installed on your machine. For a team that lives in a browser and only needs light document editing, Basic does the job.
Business Standard adds the proper desktop Office apps, the ones you install and run locally with the full feature set. This is the plan most small teams settle on, because plenty of real work still happens in a desktop spreadsheet or a heavily formatted document, and the web versions can feel thin once you push them.
Business Premium is Standard plus a security and management layer. That means tools like Microsoft Intune for managing company devices and Microsoft Defender for added threat protection, along with more control over identity and access. It suits businesses with compliance obligations, sensitive client data, or simply a low tolerance for a laptop going missing with the company’s files on it.
A quick comparison
The table below is a simplified view. Microsoft adjusts what sits in each tier from time to time, and there are user-count caps and add-ons that change the picture, so treat this as a map, not the territory.
| Feature | Basic | Standard | Premium |
|---|---|---|---|
| Exchange email, Teams, OneDrive, SharePoint | Yes | Yes | Yes |
| Web and mobile Office apps | Yes | Yes | Yes |
| Desktop Office apps (installed) | No | Yes | Yes |
| Advanced security (Defender) | No | No | Yes |
| Device management (Intune) | No | No | Yes |
Pricing is per user per month and shifts with currency, promotions and Microsoft’s own changes, so we have deliberately left dollar figures out. Check the official Microsoft 365 business plans page for current Australian pricing before you commit, and remember that an annual commitment usually costs less per month than paying month to month.
How to actually choose
Start with the desktop question. If your team genuinely works in browser tabs and a phone, Basic may be enough and you can always upgrade later. The moment someone says “but I need real Excel”, you are looking at Standard. That single line decides most cases.
Then ask the security question. If you handle health records, financial data, legal files, or anything covered by privacy and compliance rules, Premium’s extra protection and device management earn their keep. The same goes if staff use their own laptops and phones, where you want a way to wipe company data from a lost device without touching someone’s holiday photos.
A few prompts to run through with whoever signs off:
- Does anyone need installed desktop apps, or will the web versions do?
- Do we handle data that carries a compliance or privacy obligation?
- Are staff on company-owned devices, personal ones, or a mix?
- How painful would a lost or stolen device be, realistically?
- Do we want one plan for everyone, or different tiers for different roles?
That last point matters. You do not have to put the whole team on one plan. It is common to give most people Standard and a smaller group, say anyone touching sensitive systems, Premium. Mixing tiers is allowed and often the most sensible spend.
Why the setup matters more than the plan
Here is the part the marketing pages skip. The plan you buy is a fraction of the value. The rest lives in how it is configured: how user identities are created and secured, whether multi-factor authentication is switched on, and how your SharePoint sites and Teams are structured so files end up somewhere findable rather than scattered across personal OneDrives.
Buying the licence is the easy 10 percent. The other 90 percent is identity, security and structure, and that is where most rollouts quietly go wrong.
This is precisely where things go sideways. A team rushes the rollout, skips multi-factor authentication, lets everyone save to their own OneDrive, and six months later nobody can find anything and the security posture is thin. Getting the foundations right, including a sensible document management system and the basics of cyber security for business, is what turns a subscription into an actual platform. If your team is short on in-house IT, it is worth getting help rolling out Microsoft 365 so identity, security and file structure are sorted from day one rather than retrofitted in a panic.
If you are still weighing up the broader toolkit and how Microsoft 365 fits alongside everything else a small firm runs on, our wider guide to choosing business software in Australia puts it in context.
The bottom line
Most Australian small teams should look hard at Business Standard, step down to Basic only if nobody needs installed desktop apps, and step up to Premium when security and compliance demand it, or mix tiers by role. Whichever you choose, budget time for the setup. The licence is a small line item next to the cost of a messy, insecure rollout.
