Somewhere in most growing businesses there’s a meeting that goes a bit like this: someone in finance wants proper Excel because the accountant sent over a spreadsheet full of macros that break in Google Sheets, someone in marketing swears by Google Docs because three people can comment on the same paragraph without anyone emailing a document called “Final_v3_ACTUAL.docx”, and the owner just wants to know why this is even a debate in 2026.
It’s a fair question. Both platforms do email, both do documents, both do video calls, and both will happily take your money every month. But underneath the shiny marketing pages, Microsoft 365 and Google Workspace are built on genuinely different philosophies, and picking the wrong one for how your team actually works costs more than a few quid a month.
If you’re trying to settle the Microsoft 365 vs Google Workspace for small business argument once and for all, the honest answer is: it depends what your team already does, not what a salesperson tells you it should do. Let’s get into why.
Why This Decision Actually Matters
Nobody sits around excited about office software. That’s precisely why so many SMEs pick whichever platform the founder happened to use at their last job, then live with the consequences for the next five years.
Getting it wrong isn’t fatal, but it is expensive in small, annoying ways. Staff waste time fighting file formats. IT support tickets pile up because nobody quite understands the sharing permissions. And switching later, once you’ve got three years of emails, shared drives and calendar invites tangled into one ecosystem, is a genuinely painful migration project, not a quick software swap over a lunch break.
Habits matter too. If your team has spent a decade in Outlook and Word, forcing them into Gmail and Docs overnight will cause more grumbling than any productivity gain justifies. Software should bend to how people already work wherever reasonably possible, not the other way round.
Collaboration and Apps: Browser-First vs Desktop-Deep
Google Workspace was built from day one to live in a browser tab. Docs, Sheets and Slides are fast, genuinely excellent for real-time co-editing, and refreshingly simple. Two people can be in the same spreadsheet at once without anyone panicking about version control. For straightforward, collaborative, cloud-native work, it’s very hard to beat.
Microsoft 365 comes from the opposite direction. Word, Excel, PowerPoint and Outlook started life as heavyweight desktop applications, and that heritage still shows. Excel remains the more powerful tool once you get into complex formulas, pivot tables, or anything an accountant would recognise as “proper” financial modelling. Word handles long, formatted documents (contracts, reports, anything with a table of contents) more gracefully than Google Docs ever has. And crucially, Microsoft’s apps still work properly offline, syncing once you’re back online. If your team travels, works on site visits, or just has patchy broadband (still a very real thing in parts of the UK), that offline strength matters more than it sounds.
Neither approach is wrong. One is simplicity by design, the other is depth by design. The question is which one matches how your people actually spend their day.
File Management and SharePoint
This is where Microsoft quietly pulls ahead for growing businesses. SharePoint, which sits behind OneDrive and Teams, gives you proper structured file libraries, granular permissions, and version history that goes deeper than “who last touched this”. Google Drive is simpler to use out of the box, no argument there, but once you’ve got twenty staff, several departments and clients who need view-only access to specific folders, Microsoft’s permission model gives admins finer control without needing a third-party tool bolted on.
Storage: Not Even Close at Entry Level
Here’s a genuinely stark difference that catches a lot of business owners out. Microsoft 365 Business Basic gives every single user 1TB of OneDrive storage, even on its cheapest tier. Google Workspace Business Starter, the entry plan, gives you 30GB, and it’s pooled across the whole organisation, not per person.
Thirty gigabytes disappears fast once you’ve got design files, recorded Teams calls, or a marketing team that likes high-resolution images. Plenty of small businesses on Google’s starter plan end up paying for extra storage within the first year, which quietly erodes any headline price advantage. Worth doing the maths on this one before you commit, not after.
Communication and Meetings
Microsoft Teams bundles chat, video calls, and file sharing into one app. Once you’re in a Teams call, the relevant files, chat history and shared documents are usually sitting right there in the same window. It’s a genuinely unified experience, even if the app itself can feel a bit heavy on older laptops.
Google splits this job across two tools: Meet for video, Chat for messaging. Both are lightweight and quick to open, which some teams prefer. But you’re juggling two separate apps instead of one, and the file-sharing experience feels a touch more bolted-on than integrated.
Security and Admin Controls
Both platforms take security seriously, and both meet standard UK compliance expectations for data protection. But the depth of admin control differs. Microsoft’s admin centre, combined with Entra ID (the rebranded Azure AD) and Purview for compliance, gives IT administrators fairly granular control over conditional access, data loss prevention and device management, even on mid-tier business plans. That’s genuinely useful once you’re handling client data, financial records, or anything covered by GDPR obligations that a regulator might one day ask questions about.
Google’s admin console is cleaner and less intimidating for a non-technical business owner to poke around in, which has its own value. But for a business that’s growing past ten or fifteen staff and starting to think properly about compliance, Microsoft’s ecosystem tends to offer more levers to pull, once someone competent is pulling them.
Pricing and Value
Right, the bit everyone actually wants to know. At the time of writing, Microsoft 365 Business Basic starts at roughly £5 to £6 per user per month, while Google Workspace Business Starter sits in a similar bracket, sometimes very slightly higher depending on whether you commit annually or pay flexibly. Neither is dramatically more expensive than the other at entry level, and both companies adjust pricing periodically, so treat any figure you read (including this one) as a snapshot, not gospel. Check the official Microsoft 365 pricing page and Google Workspace pricing page directly before budgeting, because both have shifted their numbers within the last year.
Where the value equation tips is that 1TB storage allowance on Microsoft’s cheapest tier. Pound for pound, you’re getting considerably more raw storage without upgrading, which matters more than a one or two pound monthly difference once you factor in what Google’s pooled 30GB actually costs you in upgrades down the line.
AI Add-Ons: Gemini vs Copilot
Let’s be straight about this one, because it’s the point where Microsoft genuinely comes off worse. Google bundles Gemini directly into its standard and higher Workspace plans at no extra charge. It’s just there, sitting inside Docs, Gmail and Sheets, ready to go.
Microsoft Copilot, by contrast, is usually a separate add-on with its own monthly fee, and it isn’t cheap. Some newer Microsoft 365 bundles now include a lighter Copilot experience baked in, but the full Copilot capability most businesses actually want still typically costs extra on top of your base subscription. If AI assistance is a genuine priority for your team right now rather than a nice-to-have, Google currently has the fairer, more transparent pricing story. No point pretending otherwise.
Which Should You Choose?
Choose Google Workspace if: your team is small, comfortable working entirely in a browser, doesn’t handle complex spreadsheets or long formatted documents, wants AI features included rather than bolted on, and values simplicity over deep configurability.
Choose Microsoft 365 if: your team already knows Word, Excel and Outlook, needs proper offline access, handles large files or wants generous storage without extra cost, is starting to care seriously about compliance and admin control, or is likely to scale past a handful of staff within the next couple of years.
Neither answer is universally right, and anyone telling you otherwise is selling you something.
The Real Answer Is Proper Setup, Not Just the Platform
Here’s the thing nobody puts in the marketing brochure: the “best” platform for your business is the one that’s set up properly, with sensible permissions, sound backup practices, and someone who actually understands the admin panel rather than clicking around it hoping for the best. A brilliant platform badly configured causes just as many headaches as the wrong platform configured well.
For most growing SMEs weighing up Microsoft 365 vs Google Workspace for small business use, the practical edge tends to sit with Microsoft, mainly down to storage, offline resilience and the depth of admin control as you scale. That said, this only pays off if someone competent handles the setup and keeps an eye on it afterwards, which is exactly the kind of unglamorous, ongoing work an outsourced IT partner like Your IT Department tends to be brought in for. Not to sell you a platform, just to make sure whichever one you pick actually works the way it’s supposed to.
Getting proper guidance at the start, rather than untangling a mess eighteen months in, is the bit that genuinely saves money. Your IT Department and firms like it exist precisely because most business owners have better things to do with their Tuesday than argue about SharePoint permissions.
The Bottom Line
Pick the platform that matches how your people already work, budget honestly for storage and AI extras, and get someone competent to set it up properly. Do that, and the Microsoft versus Google argument stops being a headache and just becomes a sensible business decision.
