Appointment Booking Form

Adding your booking form to a page is as simple as inserting the above shortcode. You can search for it by name or find it in the Ultimate Appointment Scheduling block section. With the block, you can also insert your booking form into any widget area in your theme. Ultimate appointment booking flexibility!


Alternatively, you can simply insert either of the appointment booking shortcodes above into any page to display a responsive booking form. The first will display a booking calendar, from which you can select and reserve an appointment time. The second will allow you choose a date and then display available appointment booking times that are available for you to book a reservation.

Allow your visitors and customers to book reservations for a wide array of services and appointment types. With options to create an unlimited amount of unique appointment services, to specify multiple different appointment locations, and to create service providers and specify the services they do, the booking locations they work at and their hours, all with an easy-to-use reservation form on the front end, Ultimate Appointment Scheduling provides the most simple and effecting booking solution and reservation system that is perfect for both you the admin as well as your site visitors.

The plugin comes with a flexible array of email notification and reminder options. You can configure it to automatically send a notification to the admin and to the customer when a new booking is made.

You can create an unlimited number of custom email messages, which you can assign to your different notifications.

You can also create an unlimited number of reservations reminder notifications, which will allow you to send out emails to your customers at the exact time intervals you need, to help remind them of their upcoming appointments.

  • Set the amount of time between appointments. This, combined with the duration set for a service, will decide when appointment reservations can made.

  • Click on Options and then choose the Basic area
  • Write down your CSS code in the Custom CSS text area
  • Click “Save Changes” to save your changes

How do I add new fields to the booking form?

To create custom fields, you need to go to the Custom Fields tab and simply add a new field. Do not forgot to set their options (slug, type and input values) properly in order to prevent confusion.

Can I redirect to another page after the booking form is submitted?

You can do this in the shortcode. For example: [ultimate-appointment-dropdown redirect_page=”http://google.com/”]

Can I limit booking to a certain number of days before the appointment

To do this, you can use the “Minimum Days in Advance” and “Maximum Days in Advance” settings in the “Basic” area of the “Options” tab.

Can I send email reminders to people about their appointments?

You definitely can. First go to the “Emails” area of the “Options” tab and create your email. Then go to the “Reminders” area of the “Options” tab, create your reminder and choose the email you want to be sent out for the reminder.

Unfortunately the plugin is badly programmed and throws lots of exceptions when you start to debug. I bought the plugin and immediately encountered multiple problems: – after the years, there is still no documentation – appointments form works without selecting a date… support had access to staging enviroment, destroied this completely and then said the database must be corrupt and I have to install WordPress again… this is strange as all other plugins work perfectly, even the new appointment plugin, which I installed afterwards and even is free with great support ! – appointments import does not work, support sent template but this did not work either, then no more response from support – appointment start times are not removed even if time has already gone by, it is not a time zone settings problem on my side, as the new plugin works without a problem There would be many more to mention. Sadly I bought the plugin and wasted over a month trying to fix and improve things with it, until I finally gave up.

There is NOTHING on the product page to indicate that there’s a Premium version of the plugin. As soon as you install it you’re BOMBARDED with crap begging you to buy their Premium version. I mean even worse than Yoast does (and that’s saying a LOT). The basic free version is pretty much useless. Typical bait and switch crap plugin. Save your time and find another solution. I’m off to do that right now myself and I’ll have no problem PAYING for a solution – as long as they don’t try to hide what they’re really trying to do.

A very good plugin. It has some really good features as standard such as acknowledging appointments, holidays and keeping a log of the appointments – albeit in the WordPress environment itself. It’s worth getting the extra features that come with the full version though. Overall, very easy to use and implement. Also very flexible at the same time. The only criticism I have would be that aligning the services and service providers are a bit fiddly at first. Otherwise, all good.
