Microsoft 365 vs Google Workspace for Small Businesses

The short answer

Choose Microsoft 365 if your team works heavily in desktop Excel and Word, uses industry software that plugs into Outlook, or runs Windows laptops you want to manage centrally with Intune. Choose Google Workspace if your team works mainly in the browser, collaborates on documents in real time, and uses Chromebooks or Macs.

Both are mature, secure and widely used by UK businesses. The wrong choice is rarely a disaster, but switching later takes time, so it is worth deciding on how your team actually works rather than on headline price.

Side-by-side comparison

Where Microsoft 365 wins

Microsoft 365 is hard to beat for businesses tied to Office files. Accountancy, legal, engineering and finance software often depends on Outlook add-ins or Excel. Clients and suppliers send complex Word and Excel documents that render perfectly only in desktop Office.

For security, Microsoft 365 Business Premium bundles Intune device management, Defender for Business and Conditional Access, which let you enforce encryption, updates and sign-in rules across Windows laptops and phones from one place. Teams is the standard for meetings in many UK sectors. See Microsoft 365 support and Intune device management.

Microsoft 365 also handles shared mailboxes, room calendars and complex email routing well, which suits offices with reception teams, shared enquiry addresses and meeting rooms to book.

Where Google Workspace wins

Google Workspace is simple, fast and built for working together in real time. Several people can edit the same document or spreadsheet at once with no version confusion, and everything runs in a browser, so new staff can be productive on any device within minutes.

Gmail's search and spam filtering are widely liked, and the admin console is straightforward for small teams. It pairs naturally with Chromebooks, which are inexpensive and easy to manage. For creative and startup teams on Macs, it avoids some of the friction of Windows-centred tools. See Google Workspace support.

How to decide in practice

Ask three questions. First, does any software you rely on need Outlook, Word or Excel on the desktop? If yes, Microsoft 365 is usually the answer. Second, what devices does your team use? Windows laptops point towards Microsoft, while Chromebooks point towards Google, and Macs work well with either. Third, how do people collaborate? Teams that edit the same documents together all day often prefer Google, while teams exchanging finished documents with clients often prefer Microsoft.

If the answers are mixed, Microsoft 365 is generally the safer default for UK professional services, because clients and suppliers expect Office files. Google Workspace remains an excellent choice for browser-first teams that value simplicity. You can also trial either with a few users before committing the whole business.

What is the same either way

Whichever you pick, a few things do not change. You need MFA on every account. You need SPF, DKIM and DMARC on your domain so your email is delivered and harder to spoof. You need sensible sharing settings so files are not left open to anyone with a link. And you need a separate backup, because neither provider's retention is a full backup you control.

We set up, secure and support both. Moving between them is a project that covers mailboxes, calendars, contacts, files and sharing permissions, and is quoted. See cloud migration and our pricing.
