WooCommerce Appointments is the ultimate WordPress appointment booking plugin that seamlessly integrates with WooCommerce and Google Calendar. This powerful plugin offers a wide range of features and benefits for businesses looking to streamline their appointment scheduling process.

Key Features:

1. Built on WooCommerce: With WooCommerce Appointments, you can leverage all the features and extensions of WooCommerce without compromising your shop’s integrity. Accept payments through all the payment gateways supported by WooCommerce.

2. Quick Setup: Installing and using the plugin is a breeze. It is intuitive, user-friendly, and does not require any programming knowledge or staff training.

3. Extra Form Fields: Customize your appointment booking form with add-on fields such as checkboxes, options, inputs, color swatches, and uploads. Each add-on field can include an additional cost and duration for the appointment.

4. 2-way Google Calendar Sync: Keep your appointments synchronized effortlessly with 2-way sync between your Google Calendar and website. Events from your Google calendar will automatically update on your site, and vice versa. Staff members can also sync their own Google calendar with their appointments only.

5. Staff Management Login: Assign multiple staff members to appointments, manage individual calendars for each employee, and allow them to set their availability according to their preferences.

6. Flexible Availability, Capacity, and Pricing Rules: Set custom availability rules for each calendar date, day, or hour. Add breaks for holidays and prioritize availability rules. Adjust the capacity of available slots to accommodate more customers during busy periods or reduce availability when needed. Configure custom pricing rules based on specific dates, days, hours, or combinations, and even set different prices for each staff member or quantity booked.

7. Timezone Conversion: Automatically convert available time slots to the visitor’s timezone. Customers will see appointments in their selected timezone in emails, orders, and account details, while staff will always view appointments in the site’s timezone.

8. REST API: WooCommerce Appointments fully integrates with the WordPress and WooCommerce REST API. This allows you to access and retrieve all Appointments data using JSON format requests. It uses standard HTTP verbs, making it compatible with most HTTP clients.

Additional Benefits:

Licenses

Even though the code is mostly the same as for other vendors, we offer you a free tool to simplify site management and security for you. Most of our plugins are pre-activated. Some need an activation key that we provide for you.
