Simply Schedule Appointments

Simply Schedule Appointments

Looking for a scheduler that works inside your WordPress site? Simply Schedule Appointments is a plugin that keeps bookings on-brand and in-house. See why it's a favorite among WordPress users.

If your website runs on WordPress and you’re looking for a scheduling tool that integrates beautifully without extra platforms, Simply Schedule Appointments could be your perfect match.

Unlike other schedulers that live on external pages or dashboards, this tool is designed specifically as a WordPress plugin. That means you don’t need to send your clients off-site or juggle third-party tools — you control the booking experience directly from your own website.

Why People Love It

  • It’s WordPress-native: You install it like any other plugin, and everything — from setup to booking to reminders — is managed right inside your WordPress dashboard.

  • Easy to customize: From fonts to colors to layout, it’s built with customization in mind, so your booking pages feel 100% on-brand.

  • Great user experience: Clients can book seamlessly, and the backend is designed to be clean and beginner-friendly for business owners.

  • Multiple calendar integrations: Works with Google Calendar, Outlook, and more.

  • Developer-friendly: For advanced users, there’s even API access and custom hooks for deeper integrations.

Pricing

Simply Schedule Appointments operates on a yearly billing model (not a one-time payment or monthly subscription). There’s a free version that you can check out here with basic features, but most users upgrade to one of their paid plans to unlock advanced scheduling options, team calendars, Zoom integrations, and more.

Plans start around $99/year, depending on your needs, and all paid plans include premium support and updates.

Who It’s Great For

  • Coaches, consultants, and service providers with a WordPress website.

  • Designers or developers building booking functionality into client sites.

  • Solo business owners who want branding control without monthly SaaS fees.

A Quick Heads Up

Because it’s a plugin, you need to be using WordPress to make the most of it. If you’re on Squarespace, Wix, or Webflow, this one isn’t for you — but for WordPress users, it’s a dream. To learn more about how Simply Schedule Appointments can help, click here.
