This feature completely removes the tedious chore of manual data entry, saving hours per week and ensuring your expense records are accurate and up-to-date.

SoloTools
AI-Powered Proposal Generation
Go beyond basic templates with an AI that writes and refines your proposals. It doesn't just fill in blanks; it generates compelling executive summaries, detailed scope breakdowns, professional pricing tables, and persuasive terms tailored to your specific project details. You describe the project in a few words, and in about 12 seconds, you have a complete, client-ready draft.
Intelligent AI Section-Level Editing
Maintain full creative control with powerful, context-aware editing tools. For any section of your proposal, you can instruct the AI to "Make more persuasive," "Make shorter," "Make more detailed," or "Rewrite in formal tone." This allows for rapid refinement and customization without starting from scratch, ensuring the final document perfectly matches your voice and goals.
Complete Client Experience & E-Signatures
Manage the entire proposal journey within SoloTools. Send proposals directly to clients via one-click email with a personalized message. Clients can then view the proposal, and you can collect legally-binding e-signatures where they draw their signature directly on the document. Set expiry dates to create urgency and automate follow-up reminders to keep the process moving without manual chasing.
Proposal Analytics & Real-Time Tracking
Gain valuable insights into your business performance. Track every proposal through a clear conversion funnel from "Sent" to "Viewed" to "Accepted/Declined." Receive real-time email notifications the moment a client opens your proposal for the first time, allowing for perfectly timed follow-ups. Understand your win rate and average close time to refine your approach.
Use Cases
Invoice Guru
On-Site Job Completion and Immediate Invoicing
A plumber finishes a repair at a client's home. Before even packing up their tools, they open the Invoice Guru app on their phone, select the client from their list, add the service items, and tap send. The client receives a professional PDF invoice via email instantly. This immediacy impresses clients and dramatically shortens the payment cycle, improving business cash flow.
Streamlining Expense Management for Tax Time
A painter purchases materials from multiple suppliers throughout the week. Instead of collecting a pile of receipts to manually enter later, they use the OCR receipt scanner feature in the app to photograph each one on the spot. At tax season, all expenses are perfectly logged and categorized, making it effortless to generate reports for their accountant or for HMRC compliance.
Managing International or Multi-Currency Clients
An electrician based in the UK regularly works for clients in other European countries. Using Invoice Guru, they can quickly generate invoices in the client's local language and currency (e.g., Euros), with all date and number formats adjusted automatically. This professionalism facilitates smoother transactions and payments from international customers.
Automated Payment Reconciliation for Busy Tradespeople
A busy landscaping company sends out dozens of invoices per month. By using Invoice Guru's bank integration, their incoming payments are automatically matched and reconciled against outstanding invoices. The business owner no longer spends hours each week checking bank statements; they simply open the app to see a clear, updated overview of their financial status.

Create persuasive proposals for campaign-based work like SEO audits, content marketing, or social media management. Leverage the AI's ability to write compelling executive summaries that focus on ROI and business outcomes. Use the e-signature feature to secure contracts for retainer or project-based work swiftly.
