This article collects the questions people ask before they subscribe. Questions about setup and day-to-day use are in the Cal.com FAQ.
Q: Which calendars are supported?
Cal.com connects to Google Calendar and Outlook Calendar with two-way sync — anything already on your calendar makes the matching slot disappear from your booking page automatically, so it can't be double-booked.
"Two-way" is the important part. With write-only sync the system doesn't know you're already busy, and clashes happen.
Q: What does the booking URL look like? Can I use my own domain?
Every instance gets its own subdomain with automatic SSL. You can also connect your own domain so the booking link sits under your own brand.
That's the most visible difference from SaaS booking tools — you don't have to send customers off to somebody else's domain.
Q: If I switch from Calendly, what happens to the old links?
This is the genuinely hard part of changing booking systems, because those old links are no longer in your hands — they're in customers' address books, in quotes you've emailed out, on your business cards.
The recommended approach is to overlap for a while rather than cancelling the old service the moment the new one is set up. How long to overlap depends on your furthest-out booking and how often you send emails containing the link. The full plan is in migrating from Calendly to Cal.com.
Q: Can a team use it together?
Cal.com supports team features, including scheduling rules like round-robin assignment.
That said, if all you need is "a few people who each have their own booking link", you don't need team setup at all — just create separate event types.
Q: Can I charge for bookings?
Cal.com supports paid bookings. This is typically used for consultations, classes and professional services.
Q: I only book the odd meeting — do I need a whole system?
Honestly: probably not. If all you need is to schedule someone occasionally, Google Calendar's appointment slots may well be enough.
The value of Cal.com is in the rules — multiple event types, buffer times, daily caps, team assignment. If you never use those rules, what you save isn't just the monthly fee but the effort of maintaining a system.
The test is: is "finding a time" actually draining you?
Q: Is self-hosting cheaper?
Cal.com is open source, so you can self-host it. But it differs from other self-hosted services in one way: installing it only gets you to the starting line. What really takes time is the Google Calendar OAuth integration and the notification email setup.
Notification email especially: a self-hosted sender has no reputation history, and if the confirmation email lands in spam, the booking effectively never happened — and neither side finds out. The cost breakdown is in self-hosted vs. managed.

Customer experience
Q: Do customers need an account to book?
No. A customer opens your booking link, picks a slot, enters a name and email address, and that's it — no account required. The confirmation email and calendar invite are sent to them automatically.
Q: What do both sides receive after a booking?
Both sides get a confirmation email and a calendar invite; if you've connected a video service, the Google Meet or Zoom link is attached automatically. Reminder email timing is configurable too, which cuts down on customers forgetting to show up.
Q: What if a customer needs to reschedule at short notice?
The confirmation email contains reschedule and cancel links, so customers can do it themselves, and both calendars update automatically afterwards — no more back-and-forth messages to find a new time, which is usually the most noticeable improvement after adopting a booking system.
Q: Can I try it first?
Yes. Request a free trial on the Free Trial page and our team will set it up for you. No credit card is needed and nothing is charged automatically when the trial ends; paid plans are monthly with no contract. Sending the booking link to a few regular customers and running a real cycle through it is the fastest way to evaluate it.
