There are four main sections of the App, seen at the bottom of the screen. MyEnergy is the third section, where you can view the proposal as your customer will see it.
When you send a proposal out via email to a customer, MyEnergy is the interactive proposal page they will see. From this page, customers can view different system and payment options, see financial results corresponding to system options, and accept the proposal. The proposal can also be downloaded as a PDF, and is completely customizable.
See Crafting and Sending Proposals for more information about how to use this section of the App.
