Baza Booking Calendar vs Simply Schedule Appointments

Simply Schedule Appointments (SSA) is a WordPress appointment plugin known mainly for its simple setup and a solid free version on WordPress.org. It works well for anyone who wants a basic booking calendar without extra complexity. Baza Booking Calendar takes a different path: more built-in capabilities right in the paid plans, with no need to purchase separate extensions.

In this article we compare both plugins honestly, with no declared winner, based on what your business actually needs.

Notifications

Simply Schedule Appointments covers the basics through email, with SMS available on the paid tier. Baza Booking Calendar’s Pro plan sends notifications across several channels at once: Telegram, Viber, WhatsApp Business, SMS through Twilio, TurboSMS, or Lifecell, plus email with a custom HTML template. For a business whose customers live in messaging apps rather than their inbox, that makes a real difference in how quickly the owner sees a new booking.

Customer account and loyalty

Baza Booking Calendar’s customer account (Pro+) includes its own login system with no third-party plugins, with “My Bookings”, “Loyalty”, and “Profile” tabs, plus a loyalty program that applies a discount automatically based on purchase totals. Simply Schedule Appointments focuses more on the booking flow itself than on building a long-term relationship through a customer account.
