Proposa allows you to create quick, slick online proposals. But be aware that some of the advertised features on AppSumo are not yet available.

The user interface has limited editing functions, making it easy to learn. It took me about 30 minutes to create my first proposal. With the ability to save specific sections, I imagine it might only take a few minutes to produce future proposals.

You can create a proposal from scratch or use one of the ready-made templates. It doesn't matter which template you start with because you can change the theme after adding your content and easily rearrange the different sections.

Stock images from Unsplash are available within the program, and you can import graphics and artwork from your linked Dropbox and Google Drive accounts.

The Viewport shows you what your proposal will look like on smartphones and tablets. You can check this while editing the content to see how it flows on different platforms.

When you finish the proposal, you can copy a link to the online and PDF versions to send to your clients. Or can send the proposal directly from the software. But be aware you can not edit that email. You don't even see a preview of the message. (See additional comments below.)

Some things you need to know:

Proposa's videos and documentation show you how to animate the text in your proposals (fade-in, slide-in, etc.) That function is not yet available in the software. The templates have animation built-in, and currently, you can not adjust or delete the animations.

There are three license tiers available on AppSumo. Tiers 2 and 3 are supposed to include White Labeling and Behavior Analysis.

Regarding White Labeling, Proposa's website (https://proposa.io/features/white-labeling/) says, "Your Brand. Not Ours. There will be no mentions of Proposa anywhere." That's only partially true. There is no Proposa brand anywhere on the actual proposal. Still, the email comes from Proposa and includes Proposa's logo and links to Proposa's social media and customer support site. I sent a test proposal to two colleagues. One of them deleted the email because it looked like junk mail.

The Behavior Analysis (https://proposa.io/features/heatmaps-behavioral-analysis/) only partially works. You get notification emails every time your client looks at the proposal. However, the heatmap function is not currently available to AppSumo subscribers.

There seems to be some disconnect between the software developers and the marketing team. Some advertised features are not yet available. I contacted customer support about the discrepancies and was told "engineers are working on it," and the features will be available soon.

Compared with the cost of other digital proposal software options, Proposa on AppSumo is a good deal! But the software feels like it's three-fifths finished, so that's what I'm giving it for a rating at this time.
