Microsoft 365 Licensing: A Plain-English Guide for Small Businesses

Microsoft 365 licensing is one of those topics that makes sensible people’s eyes glaze over. It doesn’t have to. Here’s how to think about it.

The three licences most SMBs need to know

Business Basic gives your team email (Exchange), Teams, OneDrive and the web versions of Office apps. It’s ideal for staff who mostly work in a browser and don’t need desktop Word or Excel.

Business Standard adds the full desktop Office apps. If someone lives in Excel or PowerPoint, this is usually the right call.

Business Premium adds the important bit: advanced security (Defender for Business), device management (Intune) and conditional access. For anyone handling sensitive client data, the upgrade often pays for itself by replacing several separate security products.

Common ways businesses overspend

• Premium for everyone. Front-line or part-time staff who only need email may be fine on Basic.
• Duplicate products. If Business Premium already covers your antivirus and MDM, you may be paying twice.
• Ghost licences. Leavers who still have licences six months later — an audit usually finds them fast.

Common ways businesses underspend (and pay later)

• Basic with no security layer. It works until the first phishing attack, then it becomes very expensive.
• Personal Outlook/Google accounts for business email. Unprofessional, insecure and hard to reclaim when staff leave.

A practical approach

1. Group your staff by what they genuinely do each day.
2. Match each group to the cheapest licence that safely covers it.
3. Make sure someone is reviewing licences at least annually.
