A simple comparison to help you pick the platform that fits how your team works.
Both platforms do email, files, and collaboration well. Microsoft 365 tends to fit businesses that rely on desktop Office files, Windows computers, or industry software built around them. Google Workspace tends to fit businesses that work almost entirely in the browser and value simplicity.
Microsoft's admin experience is powerful and more complex. Google's is lighter and easier to navigate. If nobody in-house will administer it, that difference matters less than having someone accountable for it either way.
Entry business plans on both platforms land in a similar range per user per month. Cost differences usually come from the tier you need for security features, archiving, or storage — not the base license.
Migrations are routine when planned: mail, files, calendars, shared mailboxes, and permissions move over on a schedule with a short overlap period. They go badly when they are rushed. Either way, the platform should be a business decision, not a technical preference.
