Prospero review

Prospero aims at freelancers and small studios that want good-looking proposals without per-document limits. Pricing starts at $12 a month on annual billing, or $19 month to month, for an individual, and the price rises with the number of team members you select. Every plan includes unlimited proposals and proposal emails, a generative AI assistant that can change tone, length and wording or generate images, analytics that show who opened a proposal, for how long and on what device, and automated reminders. The editor offers more than 100 templates, variables, version history, an interactive pricing module, file attachments and PDF export. eSignature works on desktop and mobile and records timestamp, IP and device information for two signers. Integrations cover Stripe, QuickBooks, FreshBooks, Xero, Make, Zapier, Slack and Monday.com. Team features include user management, content locking and proposal tags. Sales teams that need CRM-driven quoting or approval rules will find more in PandaDoc or Proposify.
