This article is in the Projects > Design section of the App.
Within the Design tab, you are able to view and apply incentives to a project . Incentives that are set-up in the Control zone (see How To Set Up Incentives) as a default will be applied automatically, but you can override this and apply any incentives from your list on a per-project basis.
Note: For projects in the US, the 26% ITC is set as a default incentive for all projects. You can edit this in the Control zone.
To override incentives, first ensure that the System Option that you wish to override the incentives for is selected by clicking on the system tab in the top toolbar. Once you've done this, see Pricing & Payment Options on the left hand side-bar and click the drop down menu under Incentives:
Click on "Override Default Incentives", and this will assume that no incentives are applied. Your entire list of incentives will appear for you to choose from. You can then manually select the incentives you would like to include for this system design.
You can also create custom incentives within Design, which will be applied only to the project you are currently working on, by clicking on the "+" icon. Enter a title and dollar value, which can be claimed by either the installer or the customer.
