Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
OnceHub
Scheduling with a phone number attached
OnceHub does the booking page and the routing every scheduler does, then hands the booking a dedicated phone number, so a call that was always going to happen on the phone gets booked and dialled from one record. Free covers one link and one calendar. Past that it is priced per seat, and the routing tier costs about twice the basic one.
Our note
Against Calendly and Cal.com this is the pick only if the phone number or the routing matters, since both of those do plain scheduling for less. On the free tiers the three are close enough that the deciding factor is which one your calendar prefers.
Square Appointments
Booking and payments in one account
Square Appointments runs a booking site, staff calendars and reminders, and takes the payment through Square rather than through a separate processor. The free plan covers one location with no monthly fee at all, and the processing rate is where Square earns instead. Paying lowers that rate and adds the scheduling controls a team needs. Anybody who only wants a calendar link and never takes a payment is paying attention to the wrong half of this product.
