Book is metered on the business: free for one staff calendar with unlimited bookings — a real free appointment scheduling app for one person — then $19 a month with every staff calendar included, and $39 for unlimited locations, rooms and chairs. Unlimited bookings and unlimited people on every plan, and no onboarding fee at any tier, ever . Billed in US dollars through Stripe; annual rates are proposed monthly equivalents, billed for 12 months. These prices are proposed — Book is not built and nothing is being charged.

$128 a month, because the plan is the seat Book Pro: $19, everybody included
$61 a month, because the eighth calendar does not fit Standard Book Pro: $19, unlimited calendars
$147 a month, because the meter is the location Book Business: $39 for all three
$29.90 a month, and a good month moves you up a tier Book Pro: $19, bookings never counted
If you are a single consultant taking your own bookings, the free tiers in this category are excellent and you should use one. Cal.com gives one user unlimited event types and calendars for nothing. Setmore is free for up to four users with unlimited appointments, and $5 per user a month on annual billing after that. Calendly Standard is $10 a seat and Acuity Starter is $16 to $20.
Book's argument begins at the second person who shares a diary, and it gets stronger with every one after that. Below that line we would rather say so than sell you something.

One row decides it for a clinic or a salon: what the eighth person sharing the diary costs. Everything else in this table is a detail by comparison.

Because the receptionist, the six stylists and the owner are eight seats and one front desk, and charging eight times for one front desk is how a business goes back to a paper diary. Every staff calendar is included on Pro.
A tool that charges you more when you do more of the thing the tool exists for is not on your side. Bookings are unlimited on every plan, including Free.
Locations are what Business is for, not something Pro should be punished by. Square Appointments is $49 per location per month on Plus; Book Business is $39 for all of them.
Yes: one staff calendar, unlimited bookings, real two-way calendar sync, email reminders and a customer record. A single consultant can run on it permanently. That is deliberate — SimplyBook.me's 50 bookings a month and Calendly's one event type are the two caps that make people distrust free tiers here.
From the second person. Calendly Teams is $16 per seat, so two people are $32 and eight are $128. Book Pro is $19 at any of those numbers.
For one person. Setmore is free for up to four users and $5 per user a month on annual billing after that; Cal.com and Calendly both have real free tiers; Acuity Starter is $16 to $20. If you are a solo consultant, use one of those and come back when somebody else starts sharing your diary.
No onboarding fee is proposed. Confirm the final launch terms before purchasing.
