To add applicable addons and charges to a plan, follow these steps:
Click Product Catalog > Plans. Select the plan for which you are adding applicable addons and charges.
In the Plan details page, scroll to the Applicable Addons and Charges section. All addons and charges are set as applicable by default. You can click Change and select specific addons and charges to be applicable.
Click +Attach and select Addons or Charges from the drop-down.
Attaching Addons: In the Attach an addon popup, select the addon that you want to attach to this plan from the drop down and select an applicable option and save
Attaching Charges: In the Attach a charge popup, select the charge that you want to attach to this plan from the drop down and select an applicable option and save.
The addon and charge attachment happens at a plan level, and any new price point that is added automatically inherits the applicability and conditions without any manual intervention.
