Microsoft 365 vs Google Workspace: Which Should Your Business Choose?

Microsoft 365 and Google Workspace do broadly the same job: business email on your own domain, documents, storage and video calls. Their prices are now almost identical too. The real differences are how your team works, which files your clients send you and how much IT help you have. This guide puts the plans side by side and tells you which to pick.

For small businesses, scaling firms and multinational corporations alike, choosing a primary productivity suite is rarely a simple feature comparison. Google Workspace and Microsoft 365 offer functionally equivalent core tools: email, document editing, cloud storage and video conferencing. Their market dynamics, though, reveal a real split in how businesses operate.

At a glance: who fits which suite

Plans and prices side by side

Both companies sell three business plans for up to 300 users, and since Microsoft’s July 2026 price rise their US list prices line up almost exactly. These are per user per month on an annual commitment, before tax.

In the UK, Google lists £5.90, £11.80 and £18.40 plus VAT on annual billing, which I cover in my Google Workspace review. Microsoft’s UK prices vary more between Microsoft and its resellers, and depend on whether Teams is included, so check the price you are actually quoted. Monthly billing costs more on both.

Feature by feature

Which should you choose?

If you only need email on your own domain and none of the documents or meetings, neither suite is the cheapest or most private way to get it. My Fastmail review covers the email-only route.

Why enterprises default to Microsoft

For established enterprises, adopting Microsoft 365 is seldom an active choice. It is an inherited posture. Several deep-rooted factors keep traditional corporations in the Microsoft ecosystem.

The educational pipeline

Higher education, business schools and IT administration programmes overwhelmingly train students on Microsoft systems. System administrators enter the workforce fluent in Active Directory, Exchange and PowerShell, which creates a structural bias towards Microsoft-first environments.

Perceived corporate legitimacy

Google still battles a perception in conservative boardrooms of being a consumer search engine that happens to sell email. Microsoft, by contrast, is viewed as an enterprise software partner.

The “safe choice” fallacy

Choosing Microsoft acts as an insurance policy for senior leaders. If Outlook has an outage, it is treated as an industry-wide event. If an IT director moves a traditional firm to Google Workspace and meets user resistance, it can be judged a management failure.

Compliance and governance

Google Workspace satisfies standard regulatory frameworks, but Microsoft 365’s higher-tier suites, such as E5 with Purview, offer the granular data loss prevention, legal hold and eDiscovery tooling often demanded by heavily regulated sectors. Which features you get depends on your licence, as I explain in my Outlook and Exchange review.

Deep third-party integration

Legacy enterprise resource planning (ERP) platforms, custom financial models and industry-specific software were built over decades to hook into Windows and Exchange. Replacing those connectors can introduce unacceptable operational risk.

Market share: what the numbers do and don’t show

Market share claims depend heavily on what is being counted. Counting organisations favours Google, which has huge adoption among small businesses, startups and education. Counting seats or enterprise revenue tells a different story. Be careful with any single percentage.

Google at enterprise scale

Despite the belief that Google cannot serve scale, large organisations do run on it. Google’s own customer story says Whirlpool moved around 92,000 employees onto its productivity suite, though that story dates from 2019. Check current figures before quoting any customer numbers.

Where Google Workspace wins

When an organisation intentionally rejects the Microsoft default in favour of Google, it is usually driving a cultural and operational pivot towards speed.

• Solopreneurs and early SMEs. For solo workers and micro-businesses, Google is the natural starting line. A founder can set up a custom domain, configure email and deploy collaboration tools quickly, without an external IT consultant.
• Low IT overhead. Managing identity and security policy in Google’s Admin console typically needs less specialist expertise than Microsoft Entra ID and Intune.
• Synchronous collaboration. Google Workspace was built for the browser. Microsoft has added real-time co-authoring to web and desktop Office, but many teams find Google’s document editing produces fewer file lockouts and version conflicts.
• Modern SaaS integration. Early-stage firms rely on tools such as Slack, HubSpot, Jira and Zoom. Google’s open authentication and lightweight APIs connect easily with these, whereas Microsoft tends to encourage staying inside Teams, SharePoint and Dynamics.

The point where growing firms move

Small and medium-sized enterprises frequently reach a crossroads as they scale past 20 to 50 employees.

As an SME scales, external pressure builds. Clients send complex Excel workbooks with embedded macros that break when converted to Google Sheets. External law firms and auditors ask for track changes in native .docx files. Managed service providers (MSPs) often push the business towards Microsoft 365, where reseller margins and remote management tools can be more lucrative and established.

Moving from one to the other

Both sides want your business, so both have free tools to bring mail, calendars and contacts across. Google Workspace has a data migration service in its Admin console, and Microsoft’s Exchange admin centre can migrate mailboxes straight from Google Workspace. Files are the harder part: Google Docs become Word files on the way out, and complex formatting and Sheets formulas need checking. Plan the move by department, not all at once, and keep the old accounts running for a month. My guide to switching email provider covers the order to do things in.

Frequently asked questions

Which is cheaper, Microsoft 365 or Google Workspace?

Neither by much. Since July 2026 the US list prices match at $7, $14 and $22 per user per month. Microsoft gives more storage on its cheaper plans; Google includes Meet and Gemini on every plan. In the UK, compare the quotes you actually get, because Microsoft’s prices vary by reseller and Teams bundle.

Which has more market share, Microsoft 365 or Google Workspace?

It depends on what you count. 6sense’s ranking lists far more companies on Google Workspace, while Microsoft is strongest in large enterprises and seat counts. Figures differ between sources, so check how each is measured.

Why do large enterprises choose Microsoft 365?

Habit, compliance tooling, desktop Office, legacy integrations and the perception of Microsoft as the safe choice.

Can Google Workspace work for a large company?

Yes. Google’s own customer story says Whirlpool moved about 92,000 employees onto its suite, although that story is from 2019.

When should a small business move from Google Workspace to Microsoft 365?

Often when clients, auditors or an MSP need native Office files, or when compliance needs outgrow the current plan, typically somewhere past 20 to 50 staff.

Is Google Workspace secure?

It meets standard regulatory frameworks. My post asking is Google Workspace private? goes into detail, and my Workspace review shows which security tools sit on which plan.

Do businesses switch to save money?

Rarely. Per-user licence differences are small compared with the cost of changing how an organisation works.

The bottom line

Prices are now so close that they shouldn’t decide it, and businesses rarely switch between Microsoft and Google to cut licensing costs by a few pounds per user. They switch when their organisational identity changes. Microsoft 365 remains the default tool for structured, process-driven governance, while Google Workspace serves as the engine for browser-first, collaborative execution.
