Microsoft 365 vs Google Workspace — Which Is Right for Your Business?

If you’re setting up a business, or finally moving off a tangle of personal Gmail accounts and an old server in the corner, you’ll quickly hit the same fork in the road: Microsoft 365 or Google Workspace? They’re the two dominant platforms for business email, documents and collaboration, and both are genuinely good. The honest answer to “which is better?” is “it depends on your business” — but that’s not much help, so let’s make it concrete.

What you’re actually buying

Both are subscriptions, charged per user per month, and both give you the same core things: professional email on your own domain (you@yourbusiness.co.uk), the documents-and-spreadsheets suite, shared calendars, video calls, cloud file storage and a set of admin and security controls. Getting either one set up on your domain is what proper business email setup is all about — it’s more than just creating a few mailboxes.

Where they differ is in character.

Where Microsoft 365 wins

You live in Office. If your business runs on Excel and Word — and a great many do, especially anywhere with serious spreadsheets, formatting-heavy documents or accounting work — Microsoft 365 gives you the real, full-featured desktop apps your team already knows. Google’s equivalents are capable, but a heavy Excel user will feel the difference immediately.

You want the desktop, not just the browser. Microsoft’s apps install on your PCs and Macs and work naturally offline, syncing when you’re back online. Google is browser-first by design.

Compatibility with the outside world. Because so many businesses, accountants, solicitors and clients use Office formats, staying in the Microsoft ecosystem means fewer “the formatting went wrong when I opened it” moments when files travel back and forth.

It’s the default in many sectors. Professional services, finance, law and similar fields lean heavily Microsoft. If your clients and partners all use it, matching them removes friction.

For most traditional UK small businesses, this is why Microsoft 365 tends to be the natural home.

Where Google Workspace wins

Everything is collaborative by default. Google was built for several people working in the same document at once, from a browser, on any device. If your team is younger, more remote, or simply lives in a web browser all day, Workspace can feel lighter and faster to work in.

Simplicity. The admin side is generally cleaner and less sprawling than Microsoft’s. For a small, non-technical team that just wants email and docs to work without a lot of moving parts, that’s a real benefit.

Gmail. If your staff already know and like Gmail, Google Workspace gives them the same experience with your business domain and proper business controls behind it.

The comparison at a glance

• Best if you’re spreadsheet- and Office-heavy: Microsoft 365
• Best if you’re browser-first and collaboration-heavy: Google Workspace
• Best desktop apps: Microsoft 365
• Simplest to administer: Google Workspace (marginally)
• Most common among UK professional firms: Microsoft 365
• Security when set up properly: effectively a tie

The mistakes people make

Choosing on price alone. The headline monthly figures are close enough that they shouldn’t be the deciding factor. The cost of picking the wrong fit — a team that fights the tools every day, or an expensive migration a year later — dwarfs a pound or two per user per month.

Assuming the cloud means you don’t need backups. This is the big one. Both platforms are reliable, but “the provider keeps the lights on” is not the same as “your data is backed up.” Delete the wrong folder, get an account compromised, or fall victim to ransomware, and you’ll want your own backup to fall back on. Microsoft and Google are explicit that this is your responsibility, not theirs.

Setting it up halfway. A rushed setup — no multi-factor authentication, sloppy sharing permissions, personal accounts still floating around — undermines whichever platform you chose. The platform is rarely the weak point; the configuration is.

So which should you choose?

If your business runs on Excel, deals with professional-services clients, or wants full desktop apps, Microsoft 365 is usually the safer default. If your team is browser-native, collaborative and values simplicity, Google Workspace may suit you better. Both will serve a small business well for years.

What matters far more than the badge is that it’s set up properly on your domain, secured with multi-factor authentication, backed up independently, and migrated cleanly from whatever you’re using now. That’s the part worth getting right — and the part we handle day in, day out for businesses across South London and Surrey.
