<h4>User friendly booking plugin</h4>
<p>With its reactive calendar widget and a step-by-step reservation process, TheBooking allows customers to book your services in a snap!</p>
<h4>Availability schedule</h4>
<p>TheBooking implements an intuitive weekly planner to define availability hours, vacations and day offs.</p>
<ul>
<li><strong>Weekly working hours</strong>: define the available time intervals for each day of the week.</li>
<li><strong>Closing dates</strong>: configure the day offs.</li>
<li><strong>Booking time frame</strong>: define (if needed) both reservation opening and closing time independently for any of your services</li>
</ul>
<h4>Reservation form</h4>
<p>Define and customize a reservation form for each one of your services. TheBooking ships with a flexible <strong>form builder</strong>.</p>
<ul>
<li><strong>Custom fields</strong>: add your desired fields in the reservation form to collect the data you need (even <strong>files</strong>!)</li>
<li><strong>Conditional fields</strong>: fields can be configured to show/hide or being required in consequence of values of other fields.</li>
<li><strong>Validation</strong>: apply the desired validation rule to any text field, if needed.</li>
</ul>
<h4>Zoom meetings and Google Meet</h4>
<p>TheBooking integrates with Zoom and Google Meet to automate meetings creation and management for your services.</p>
<h4>Google Calendar 2-ways and 3-ways integration</h4>
<p>Connect your Google Calendar to see all your reservations there and to block available timeslots when busy. TheBooking is the <strong>only</strong> plugin that also allows you to <strong>plan the availability directly through Google Calendar</strong> (3-way) without the need to use the plugin backend to define time slots and opening hours.</p>
<h4>Locations</h4>
<p>Each service can have one or more locations that customer will be able to select during the booking process.</p>
<p><strong>Google Maps</strong> is also supported.</p>
<h4>Notification email messages</h4>
<p>TheBooking is very powerful when it comes to build the perfect notification system for your booking system.</p>
<ul>
<li><strong>Complete stack</strong> of notifications for any action: confirm, cancel, reschedule, approve, decline etc.</li>
<li><strong>Differentiate by service</strong>: any notification can be configured independently for each service</li>
<li><strong>Dynamic content</strong>: use placeholders to put dynamic data inside notification templates, such as service details, reservation details and customer’s data</li>
<li><strong>Advanced email content editor</strong>: create amazing HTML email content thanks to the clarity and power of TinyMCE editor</li>
</ul>
<h4>Service restrictions</h4>
<p>You can configure services to be booked by registered users only. Services can also be configured to require <strong>approval</strong> of the bookings.</p>
<h4>Data export</h4>
<p>Reservations and customers can be <strong>conveniently exported</strong> in *.CSV format.</p>
