Booknetic – an online booking plugin for WordPress websites.

With this plugin, you can create an unlimited number of staff members, service lists, and descriptions, and translate them into your desired languages. It seamlessly integrates into the design of your website.

It provides email notifications and flexible text settings. Additionally, you have the option to connect an SMS module to notify clients about their booked appointments. You can also enable/disable payment modules and sync booked appointments with Google Calendar.

Additional features include:
– Ability to add discount promo codes.
– Payment options through PayPal, Stripe, and WooCommerce-integrated methods.
– Setting employee days off.
– Specifying a break time after the completion of a service before accepting the next booking.
Booked time slots are removed from the available list to prevent double bookings.
