Bookly Custom Duration

Important: All add-ons for Bookly require Bookly Pro add-on installed and activated.

Custom Duration add-on for Bookly allows you to create services with flexible duration. While booking an appointment, your customers will be able to choose its length from the predefined options, and the price will be adjusted respectively.


Setup and configuration

1. Purchase, download and activate add-on in Plugins.

2. In Bookly menu > Appearance > Service step, make sure that the box next to the Show custom duration option is checked. If so, the service duration field will be displayed on your booking form. Check Show service price next to duration if you want to display the cost for each duration option.

3. Go to Services, pick up a service and select Custom from the Duration drop-down. Once you’ve done that, you’ll see additional fields below to be configured.


Unit duration – the length of a single time step. Available options for the unit duration depend on the Time slot length (configured in Settings > General).

Minimum units – minimum quantity of time steps.

Maximum units – maximum quantity of time steps.

In the Unit price field specify the cost of one unit, so the total cost of the service will increase linearly with the increase of its duration.


Service Massage
Unit duration 30 min
Unit price $50
Minimum units 2
Maximum units 5

You’ll got the following configuration:

1h = $100

1h 30min = $150

2h = $200

2h 30min = $250

4. If you change the price of a time-flexible service in Staff Members > Services tab, you should specify the Unit price.

Important: Bookly Custom Duration add-on is not compatible with Packages add-on and Compound Services add-on.
