You have two options when applying a discount to an event.
The first option is adding the discount to a picklist line which discounts the item or the item’s total along with any applicable taxes and fees (i.e. sales tax, gratuity). To add this, you will click on the ellipsis to expand the picklist line item you’re looking to discount. Then, you will click “+ Add Discount” to input a percentage or dollar discount on the item or the total item’s price.
The second option is to add the discount at a flat rate to the event’s grand total. To do this, you will find the billing widget in the editing document and click Add A Row > Discount. You will be able to input a percentage or dollar amount to discount the grand total.
Here is also a video that shows you each method to add a discount:
