BA Book Everything

78 Quality Score

Active Installs

18/30

Popularity is modest at 10,000 active installs, which is a fraction of category leaders like Amelia (90,000) and Simply Schedule Appointments (60,000).

Update Freshness

25/25

Maintenance is perfect: last updated within days of this review, and the plugin already supports WordPress 7.0.1 ahead of most of the ecosystem.

User Rating

13/15

User ratings are solid at 84 out of 100, though based on only 20 reviews, so the sample is thin.

Support Health

8/15

Support health is a concern with zero support threads recorded, meaning there is no public track record to gauge how issues are handled.

WP Compatibility

15/15

Compatibility is excellent, requiring PHP 8.1 and WordPress 6.0+, and tested against the latest 7.0.1 release.

What It Does

BA Book Everything is a developer-oriented booking and rental engine that lets you configure custom reservation flows for assets like tours, cars, events, apartments, and yachts. Rather than shipping a fixed appointment UI, it provides the building blocks a developer needs to wire booking logic into any custom theme. It is built for speed and flexibility over an out-of-the-box scheduling experience.

Who It's For

This plugin is best for theme authors, agencies, and developers building bespoke rental or booking sites where the standard calendar-plus-form plugins are too rigid. It suits projects that need a tailored frontend, complex availability rules, or multi-asset inventory like vehicles, properties, or vessels. Non-technical site owners looking for a quick scheduling widget will not get the same value here.

Who Should Skip It

If you run a single-location salon, clinic, or consultancy that just needs an appointment calendar with payments and reminders, this is overkill. Choose a turnkey solution like Amelia or Simply Schedule Appointments instead.

The Bottom Line

BA Book Everything scores 78.01 out of 100, with standout maintenance and compatibility but weaker signals on popularity and public support. It is a sensible pick for developers who need a flexible booking engine for custom rental sites, not for non-technical users wanting a quick appointment widget. Treat the zero support threads as a flag and validate the developer documentation before committing.

Pick this if you want a polished, no-code appointment scheduler with strong UX and 60,000 installs proving it at scale.

Amelia 83/100

Pick Amelia when you need a full-featured appointments and events system with payments, SMS, and a 90,000-install track record.

Bookly 82/100

Choose Bookly if you want a configurable appointment booking plugin with a wide add-on marketplace and a familiar admin UI.

SimplyBook.me 81/100

Pick SimplyBook.me if you prefer a SaaS-backed booking system with built-in client management and industry-specific templates.

Fluent Booking 81/100

Choose Fluent Booking if you are already in the Fluent ecosystem and want a modern scheduler with deep integration.
