CalioCalio vs Microsoft Bookings: beyond Microsoft 365
Microsoft Bookings comes bundled with many Microsoft 365 subscriptions, and for teams that live entirely in that ecosystem it is the obvious first step: the booking page hangs straight off Outlook and Teams.
Its limits sit exactly there. Bookings only works with Microsoft calendars, taking payments at booking time is missing, and every staff member who receives bookings needs a Microsoft 365 licence. Calio connects Google and Microsoft calendars, lets guests pay at booking time and has a free plan that does not depend on any licence.

What does it cost?
Microsoft Bookings is not a standalone product: it is included (as of August 2026) with Microsoft 365 subscriptions such as Business Standard and Business Premium, and every staff member who receives bookings needs such a licence. Calio has a free plan that stays free; paid plans start at €8 per user per month billed yearly, with no Microsoft licence required. Always check the vendor’s current pricing.

Why people switch to Calio
Google and Microsoft, even mixed
Bookings requires every host to be in Microsoft 365. Calio connects a Google or Microsoft calendar per host, so a mixed team (or a freelancer on Gmail) joins in just fine, with automatic Meet or Teams links per meeting.
Payments and no-show fees
Bookings has no payments. With Calio guests pay at booking time with iDEAL or card through Mollie, straight into your own account, and you can send a per-event-type no-show fee afterwards as a payment request.
No licence per staff member
Every colleague who receives bookings through Bookings needs a Microsoft 365 licence. Calio’s free plan is independent of that, and the paid plans only charge per Calio user.
Frequently asked questions
I already have Microsoft 365, is Bookings not enough?
For a simple booking page inside a single Microsoft tenant it often is. Calio becomes interesting the moment you need something Bookings does not do: taking payments from guests, a team with both Google and Microsoft calendars, a group poll, AI booking in plain language, or a mail agent that reads along in the cc. Your Microsoft calendar and Teams links keep working throughout.
Does Calio work with my Microsoft calendar and Teams?
Yes. Calio syncs two-way with Microsoft 365, writes bookings into your calendar and creates a Teams link per meeting automatically. For IT administrators, calio.nl/en/microsoft-approval lists exactly which permissions Calio requests and why.
What does Calio cost compared to Microsoft Bookings?
Bookings costs nothing extra if you already hold the right Microsoft 365 licence, but that licence is the requirement, per staff member. Calio has a free plan that stays free and paid plans from €8 per user per month billed yearly, with no licence requirement for you or your guests.
