For certain business who only open by appointment our online booking tool allows your customers to add in their preferred drop-off and pick-up time(s). For other business you can add in your opening and closing times for the day. The request by feature can be used in combination if your customers want to select a time outside of your standard opening and closing times.
To enable this feature head over the Settings area and click on the Opening Hours page
On this page you can set your opening hours for your various services that you offer.
At the top of the page you can turn on the ability for customers to choose a time outside of these standard opening hours by enabling the [By Special Request] toggle option.
Then on the online booking tool your customers can add in their preferred times.
