Online booking / appointment scheduling

Also known as: online booking, appointment scheduling, online scheduling software, self-service booking

Online booking (appointment scheduling) software lets customers self-book a time slot on a business's calendar over the web — seeing real-time availability, picking a service and staff member, and confirming — without phone tag. It manages availability, reminders, rescheduling, and often payment, replacing the manual appointment book.

Online booking turns scheduling into self-service. A customer visits a booking page, sees only the slots that are actually free (synced to staff calendars and service durations), chooses a service and provider, and confirms — getting an automated confirmation and reminders. The business stops playing phone tag and reduces no-shows through reminders.

Unlike telephony tools, booking software is not metered by calls or minutes. It is priced per staff seat or as a flat monthly fee, and many vendors offer a genuine free tier for a single user. The real cost drivers are headcount (for per-seat tools), whether the features a business needs — multiple staff calendars, class/group booking, payments and deposits, no-show fees, branded/white-label pages, reminders — sit in the free or entry tier or are gated above it.

For a buyer, the comparison is less about a sticker price and more about the model (per-seat vs flat) at their team size and which capabilities are included where. A free tier that omits reminders or payments can cost more in missed appointments than a paid plan that includes them.
