An online booking system can make appointments, calendar management, payments, and customer communication much easier. Not every solution fits every business, though. I compared seven strong options for an international audience, from hosted SaaS tools to WordPress plugins.
I compared pricing, free plans, booking limits, online payments, calendar support, WordPress integration, usability, localization, and fit for different business models.
Quick comparison
For most small and mid-sized service businesses, I would choose Reservio as the most balanced option. SuperSaaS is stronger for complex rules and larger teams, SimplyBook.me for a broad feature set, and Amelia if you want the whole booking system to run inside WordPress.
| System | Best for | Free plan | WordPress | Online payments | My rating |
|---|---|---|---|---|---|
| Reservio | most service businesses | Yes – 40 bookings / 30 days | Yes, web/embed | Yes | 9/10 |
| SuperSaaS | larger teams and complex rules | Yes – 50 future bookings | Yes | Yes | 9/10 |

| Amelia | WordPress service businesses | Yes – Amelia Lite | Native | Yes on paid plans | 8.7/10 |
| WP Booking System | day-based rentals | Yes | Native | Yes on higher plan | 8.5/10 |
| WooCommerce Bookings | WooCommerce bookings | No | Native | Via WooCommerce | 8.3/10 |
My pick for most businesses: Reservio. It offers a strong balance of simple day-to-day management, mobile apps, online payments, and client management.
Reservio
Reservio is the most balanced all-round booking system for salons, wellness businesses, gyms, trainers, therapists, and other service companies. It includes a booking website, mobile apps, online payments, client management, and on higher plans calendar sync, memberships, a custom domain, and API access.
Free includes 40 bookings over the last 30 days and 100 clients. Starter raises the limit to 200 bookings, Standard to 500, and Pro provides unlimited bookings. A 14-day premium-feature trial is also available.

SuperSaaS
SuperSaaS is best for businesses that need to combine staff, rooms, equipment, group events, and more complex availability rules. Every paid plan includes the same features, and pricing is driven mainly by the number of future bookings rather than employee count.
Free supports 50 future bookings and 50 registered users. Global paid plans start at $9 per month for 100 future bookings. Staff, locations, and schedules are not billed per seat.

SimplyBook.me
SimplyBook.me is a good fit if you want a broad feature set and many integrations. It supports online payments, deposits, memberships, packages, gift cards, mobile apps, WordPress, and calendar sync.
Free includes 50 bookings per month, one provider, and one premium Custom Feature. With annual billing, Basic is $11.90 per month, Standard $24.90, and Premium $49.90. The booking limits are 100, 500, and 2,000 respectively.

Reservanto
Reservanto is most relevant for businesses that also serve customers in the Czech or Slovak markets. Its Basic plan offers unlimited bookings, clients, and services, while higher tiers add more advanced functionality and API access.
Booking systems for WordPress
If you want more control inside your own website, a WordPress plugin can make more sense than an external SaaS platform. Amelia fits service appointments, WP Booking System works well for date-based rentals, and WooCommerce Bookings is ideal when you already run WooCommerce.
Amelia
Amelia is a strong WordPress-native option for professional appointment booking. It has a free Lite version, while paid licenses add recurring bookings, deposits, calendar sync, payments, service packages, resources, and REST API access. Annual paid licenses start at around $49.
WP Booking System
WP Booking System is best suited to whole-day or date-range bookings. It works well for apartments, vacation rentals, vehicles, boats, and equipment. Personal costs $79/year, Business $149/year, and Developer $249/year.
WooCommerce Bookings
WooCommerce Bookings makes the most sense if you already use WooCommerce and want bookings inside the same cart and checkout flow. The current annual license costs $249 and supports time slots, date ranges, resources, group pricing, and Google Calendar sync.
Choose by need
The best system depends more on your business model than on raw feature count.
- General service business? Reservio.
- Large team or complex rules? SuperSaaS.
- Maximum features? SimplyBook.me.
- WordPress? Amelia.
- Day-based rentals? WP Booking System.

By business type
Choosing by business type is more useful than chasing the longest feature list.
Salons and barbers
I would compare Reservio and SimplyBook.me first.
Fitness and trainers
SuperSaaS, Reservio, and SimplyBook.me are strong starting points.
Doctors and therapists
Beyond the calendar, check data security, privacy, and the regulatory requirements that apply to your practice.
Courses and group classes
SuperSaaS is particularly strong for capacity, waiting lists, and group events.
Rentals
For day-based bookings, I would look at WP Booking System first.
WordPress
For services choose Amelia, for rentals WP Booking System, and for WooCommerce WooCommerce Bookings.
SaaS or WordPress?
For most small service businesses, SaaS is easier to maintain because hosting, infrastructure, and updates are handled by the provider. A WordPress plugin gives you more control over data, design, and store integration.
What to watch for
Do not compare monthly price alone. Check how limits are calculated, how staff are billed, payment support, SMS, calendars, data export, localization, and customer support.
Tip: You can find current promotions and coupons in the deals section.
Summary
For most service businesses, I would choose Reservio today, but there is no single ideal system for every business. SuperSaaS is better for complex rules and larger teams, SimplyBook.me for feature depth, and Amelia for WordPress.
