WooCommerce Bookings is the official WooCommerce extension that lets store owners sell appointments, reservations, rentals, or classes with bookable time or date slots. It supports fixed time slots or flexible ranges, group and individual pricing, and resources — staff, rooms, or equipment — each with its own availability to prevent double-booking. It syncs with Google Calendar and works with any WooCommerce payment gateway. It’s a paid annual extension with a 30-day money-back guarantee.
