AI-Powered Proposal Generation
This is the core magic of SoloTools. You simply describe your project in a few words, and the AI does the heavy lifting. It doesn't just fill in templates; it writes a unique, tailored proposal from scratch. It crafts persuasive executive summaries, breaks down the scope of work into clear details, structures professional pricing tables, and outlines logical timelines—all customized to your specific project details and client.
AI Section-Level Editing
Get precise control over your proposal's tone and content. For any section, like the executive summary or scope, you can ask the AI to refine it on the spot. Use simple commands like "Make more persuasive," "Make shorter," or "Rewrite in a formal tone." This allows you to perfect each part of the proposal without starting over, ensuring the final document perfectly matches your voice and your client's expectations.
Client Tracking & E-Signatures
Move seamlessly from sending to getting paid. Send proposals directly via email from within SoloTools and then track their journey. You'll get real-time notifications when a client views your proposal for the first time. Clients can review, ask questions, and sign the document electronically with a simple drawn signature, making the acceptance process legally binding and incredibly fast, all without chasing them down.
Proposal Analytics & Automation
Gain valuable insights to win more deals. The dashboard shows you a clear conversion funnel, tracking how many proposals were sent, viewed, accepted, or declined. This helps you understand what's working. You can also set automatic follow-up reminders and proposal expiry dates to create urgency, so you never have to send an awkward "just checking in" email again.
