You can offer discounts with the coupon codes that apply either a fixed amount or a percentage off from the initial price of the billing plan.
To create a coupon code please navigate to Dashboard → Billing Plans → +Coupon
You can either offer a percentage discount or a fixed amount off of the initial price. The duration of the coupon defines the billing cycles that the coupon will be applied.
The Name field defines the coupon code that the user should enter in the checkout page to apply the discount.
After creating the coupon you should select the billing plans that can be applied. Open up the properties of the billing plan you intent to offer the coupon and check the tickbox.
The coupon code is now applicable to the specified billing plan through the team workspace billing form and the checkout pages.
