Proposal Builder

Build proposals the way you think

A drag-and-drop editor that lets you see exactly what clients will see. No more guessing, no more surprises.

Traditional proposal tools force you into rigid templates or leave you wrestling with word processors. You spend more time fighting formatting than actually writing. And you never really know how it’ll look until you send it.
The Prosperus visual builder shows you a live preview as you work. Drag slides around, click to edit content, and watch your proposal take shape in real time. What you see is exactly what your client gets.

Benefits

See it as you build it

Every change appears instantly in the preview. No more toggling between “edit mode” and “preview mode” wondering if it looks right.

Easy as drag and drop!

Rearrange slides with a click and drag. Add new sections from a simple menu. Delete what you don’t need. The structure is completely in your hands.

Click-to-edit- everything

Click any section to open an editor. Make your changes, close the panel, and see it reflected immediately. No hunting through menus or navigating complex interfaces.

Autosave keeps you covered

Every change appears instantly in the preview. No more toggling between “edit mode” and “preview mode” wondering if it looks right.

How It Works

1. Start fresh or use AI
Begin with a blank proposal or let AI generate a draft based on a quick project brief. Either way, you’re starting with something on the page.

2. Add and arrange slides
Use the slide menu to add sections — about, services, timeline, pricing, case studies, custom content. Drag them into whatever order makes sense for this particular pitch.

3. Edit inline
Click any slide to open its editor. Fill in the details, format the text, adjust the layout. Close the editor and your changes appear instantly.

4. Preview and publish
Toggle the full preview to see exactly what clients will see. When you’re happy, hit publish and send.

Use Cases

The quick turnaround
Client calls at 3pm wanting a proposal by end of day. With the visual builder, you can assemble a professional proposal in under 20 minutes using your saved services and case studies.

The complex pitch
Big project with multiple phases, custom terms, and a detailed timeline. Add as many slides as you need, rearrange them to tell the right story, and make sure nothing gets missed.

The repeat client
Clone a previous proposal with one click, swap out the project details, and send. Most of the work is already done.
