Which online booking tools charge a flat monthly fee?
5 of 17 tracked booking & scheduling tools charge a flat monthly fee that does not multiply by staff count: TidyCal, Bookeo, Acuity Scheduling, GlossGenius, Square Appointments. The cheapest flat paid entry is TidyCal at $12/mo. Flat pricing is predictable for a multi-staff front desk because adding a team member does not add a per-user charge — though some flat tools still cap staff logins or bookings per tier.

Frequently asked
- What is a flat-rate booking tool?
- It charges one fixed monthly fee regardless of how many staff use it, unlike per-seat tools that bill per user. That makes the bill predictable as a team grows, though the flat tier may still cap staff logins, calendars or monthly bookings.
- Is flat-rate cheaper than per-seat?
- It depends on team size. For one or two staff a per-seat tool can be cheaper; once several people need calendars, a flat fee like TidyCal at $12/mo often undercuts a per-user rate multiplied by headcount.
- Do flat plans cap anything?
- Often yes — a flat tier may limit staff logins, the number of bookable calendars, or appointments per month, with higher tiers lifting the cap. We record the published cap in each vendor profile where the vendor states it.
