To get started, fist click New Proposal in the upper-right hand corner of the screen.
Depending on the type of proposal you are creating, you will click either New Event Proposal or New Wedding Proposal
After this, simply fill out the information as needed for the proposal. Fields are not required, so you can use fields you need and ignore those you don't!
Please note: Settings may need to be setup under Settings > Event Settings for customizing your proposals.
