Prospero

Prospero is a tool for creating professional-looking quotes and commercial proposals in minutes: polished templates, built-in digital signature, and the ability to see exactly when the client opened and read the document.

Prospero is a platform for creating commercial proposals, quotes and contracts, designed for freelancers, agencies and small businesses. The editor lets you build structured documents from ready-made templates — for marketing, design, web development, consulting, photography and many other sectors — customizing text, colors, logos and pricing. Proposal sections are added and reordered modularly: introduction, scope of work, timeline, pricing, terms and conditions. Once complete, the proposal is shared with the client via link or email, who can approve it with a digital signature directly in the browser, with no printing or installation needed. The built-in tracking shows how many times the client opened the document and how much time they spent on each section — useful information to gauge interest level and find the right moment for follow-up. Approved quotes can be converted into invoices directly from the platform. Integrations with Stripe, PayPal and other gateways let you receive an upfront payment directly from the proposal.

For freelancers, agencies and professionals who regularly send proposals and quotes to clients and want a faster process with built-in digital signature and tracking.

Prospero has a free plan allowing 1 active proposal at a time, useful for those who send few proposals per month. Paid plans start at $10 per month and unlock unlimited proposals, more templates, advanced digital signature and branding features. Annual billing offers a discount. A free trial is available.
