Is this online booking system really free?
Yes. The schedule, your public booking page, confirmation and reminder emails, the waitlist, analytics and CSV exports all work on the free plan, with no cap on appointments and no commission. Pro adds logins for your staff, card payments through your own payment provider, and the option to hide the “Online booking by CalculatorAI” line.
Do my clients need an account to book?
No. They open your link, pick a service, a specialist and a free time, leave their name and whatever contact details you ask for, and book. The confirmation comes with a calendar file and a private link where they can move or cancel the visit up to the deadline you set.
How do clients pay, and do you take a cut?
The money never passes through us, so there is no commission. You show your payment details (a Zelle or Venmo handle, a Cash App $cashtag) or your own PayPal.me, Stripe or Square link, ask for the full price, a fixed deposit or a percentage, and confirm when it arrives. Card payments through your own provider are a Pro option, available today in Europe, the UK, Türkiye and Ukraine.
Can two clients book the same time slot?
No. The database itself refuses a second appointment that overlaps the first for the same person, buffers included. If two clients press Book in the same second, one gets the slot and the other is shown the times still free. A repeating series skips the dates that collide instead of double-booking them.
Does it send appointment reminders to clients?
Yes. A client who leaves an email gets a confirmation, a message whenever you confirm, move or cancel the visit, and a reminder about 24 hours before. Clients can also switch on free Telegram reminders with “I'll be there” and “Can't make it” buttons. SMS reminders are not offered.
Can my staff have their own logins?
Yes, with Pro. Invite a specialist by email and choose whether they see only their own appointments or the whole schedule, and whether they can edit or only view. Prices, payments, client cards and settings stay with you. Viewing is free for the colleague; a colleague who edits needs their own Pro.
Can I add online booking to my own website?
Yes. Besides your link and a QR code, the Widget tab builds blocks for your team, your services and a floating Book button. Paste two lines of code into WordPress, Wix, Webflow or any builder that accepts HTML. New prices, photos or people reach your site by themselves, with nothing to re-paste.
Does it sync with Google Calendar?
Not both ways. Clients get a calendar file and an “Add to Google Calendar” link with every booking, and your own visits appear on the workspace calendar on CalculatorAI, where you can confirm a request or mark a visit done. Your schedule is not pushed to or read from an outside calendar.
