Picking the right Microsoft 365 plan comes down to three things: how many people need email, whether you need the desktop Office apps, and what level of security your business requires. Most small businesses do well with Microsoft 365 Business Basic or Business Standard, while organisations with stricter compliance needs or more than 300 users should look at the Enterprise tiers.
That's the short answer. But let's break down what actually differs between plans so you can make a confident choice without overpaying—or finding out six months later that you're missing something critical.
What's actually included in every Microsoft 365 business plan?
All the business-tier plans share a core set of tools:
- Exchange Online email with a 50GB mailbox and custom domain support
- OneDrive cloud storage (1TB per user)
- Microsoft Teams for chat, video calls and meetings
- SharePoint for internal sites and document collaboration
- Web and mobile versions of Word, Excel, PowerPoint and OneNote
The differences come in when you ask: do I need the full desktop apps? Do I need advanced security? How many licences do I actually need?
How do the Business plans compare?
Here's a straightforward breakdown of the three main plans for organisations with up to 300 users:
| Feature | Business Basic | Business Standard | Business Premium |
|---|---|---|---|
| Web & mobile Office apps | Yes | Yes | Yes |
| Desktop Office apps (Word, Excel, etc.) | No | Yes | Yes |
| Email & calendar (Exchange) | Yes | Yes | Yes |
| Teams, OneDrive, SharePoint | Yes | Yes | Yes |
| Webinar hosting & attendee registration | No | Yes | Yes |
| Microsoft Bookings | No | Yes | Yes |
| Advanced threat protection (Defender) | No | No | Yes |
| Device management (Intune) | No | No | Yes |
| Azure Information Protection | No | No | Yes |
Business Basic works if your team mostly uses browser-based apps and you've already got desktop software sorted—or simply don't need it.
Business Standard is the sweet spot for most offices. You get the full desktop apps, plus tools like Bookings (handy if clients schedule appointments with you) and proper webinar features in Teams.
Business Premium adds serious security: anti-phishing, safe attachments, device management, and data loss prevention. If your industry has compliance requirements—legal, healthcare, finance—this is usually where you need to be.
When should you consider Enterprise plans instead?
The Business tiers cap out at 300 users. If you're larger, or you need features like unlimited archive mailboxes, eDiscovery for legal holds, or advanced analytics with Viva Insights, you'll be looking at E3 or E5.
Enterprise E5 also includes the full Microsoft Defender suite, Power BI Pro, and audio conferencing dial-in for Teams meetings—useful for organisations with distributed teams who sometimes join calls from regular phone lines.
What about Microsoft 365 Apps for Business?
This one trips people up. Microsoft 365 Apps for Business gives you the desktop Office apps and OneDrive—but no Exchange email, no Teams, no SharePoint. It's designed for businesses that already have email elsewhere (maybe you're using Google Workspace for mail but prefer desktop Word and Excel). Niche, but it exists.
How do you figure out what your organisation actually needs?
Walk through these questions:
- Do staff need to work offline in Word, Excel or PowerPoint? If yes, you need Standard or higher—Basic only includes web apps.
- Are you handling sensitive client data or regulated information? Business Premium's security tools aren't optional extras in those cases.
- How many people need licences? Over 300 means Enterprise territory.
- Do you already have email? If you're migrating from an existing mail system, any Business plan includes Exchange. If you're keeping your current mail provider, Apps for Business might be enough.
- Will you run webinars or client-facing virtual events? Standard and Premium include attendee registration; Basic doesn't.

Frequently asked questions
Can I mix different Microsoft 365 plans in one organisation?
Yes. You might put most staff on Business Basic and give managers or client-facing roles Business Standard licences. Microsoft allows mixing within the same tenant.
Is there a free trial?
Microsoft offers 30-day trials for most business plans. It's worth testing with a few users before committing.
What happens to my data if I downgrade later?
Your files stay in OneDrive and SharePoint. If you drop from a plan with desktop apps to one without, users lose access to those apps but their documents remain intact.
Do I need to buy licences annually?
Monthly and annual billing options exist. Annual commitments typically cost less per user, but monthly gives you flexibility if your headcount changes often.
