Set Add-on Charge Rules
For multi-day services, you can choose how an Add-on is charged based on the booking duration, number of participants, or both.
This gives you more flexibility when offering extras such as equipment rental, meals, additional services, or other optional products.
For example, an equipment rental can be charged per participant, per day, while another Add-on can be charged only once for the entire booking.
⚙️ Set up an Add-on charge rule
Open the app > go to Services > open the multi-day service you want to edit
Scroll down to Questions & Add-ons
Click Add questions to create an Add-on field, or edit an existing Add-on
In the Add-on settings, find How customers will be charged? > choose the charging rule that best matches how you want to price the Add-on
You can choose from:
Per participant, per day
One-time

💰 Understand each charge rule
Let's use the same example to see how each option works.
Example setup
Service: Studio rent
Booking duration: 3 days
Participants: 2
Add-on: Lighting equipment
Add-on price: $20
Per participant, per day
The Add-on is charged for each participant for each day of the booking.
With our example:
$20 × 2 participants × 3 days = $120
The Add-on total is $120.
This option is useful when the Add-on cost depends on both the number of people and the booking duration.
One-time
The Add-on is charged once for the entire booking, regardless of the booking duration or number of participants.
With our example:
$20 = $20
The Add-on total is $20.
Even though the booking is for 3 days and 2 participants, the Add-on is only charged once.
Per participant
The Add-on is charged once for each participant, regardless of how long the booking lasts.
With our example:
$20 × 2 participants = $40
The Add-on total is $40.
The 3-day booking duration does not increase the Add-on price.
Example uses:
Registration fee per person
Equipment assigned to each participant for the whole booking
Welcome package for each guest
Per day
The Add-on is charged once for each day of the booking, regardless of the number of participants.
With our example:
$20 × 3 days = $60
The Add-on total is $60.
The number of participants does not affect the Add-on price.
