This feature eliminates the need for cumbersome Excel or Word templates, providing a streamlined, mobile-ready solution tailored to the user’s needs.

Automatic Invoice Numbering

Invoice Guru automatically numbers and dates each invoice according to your fiscal year settings. This feature ensures that your invoices remain organized and compliant, helping you maintain a clear financial record without manual tracking or data entry.

OCR Receipt Scanner (AI Recognition)

The innovative OCR receipt scanner allows users to take a photo of their receipts, enabling the app’s AI to extract vital information such as the supplier, date, amount, and VAT. This feature simplifies expense tracking and reporting, making it easier than ever to manage business costs while reducing the risk of data entry errors.

Smart Payment Tracking

With smart payment tracking, Invoice Guru automatically matches incoming bank transactions with unpaid invoices. Users are instantly notified of which clients have paid and which invoices are overdue, allowing for efficient cash flow management and timely follow-ups without additional manual effort.

SoloTools

AI-Powered Proposal Generation

This is the core intelligence of SoloTools. The AI does not merely fill in templates; it writes compelling, context-aware content tailored to your specific project. It crafts persuasive executive summaries, detailed scope breakdowns, professional pricing tables, and appropriate terms based on the brief information you provide. This feature eliminates the blank page syndrome, ensuring you start with a high-quality, structured document in approximately 12 seconds, which you can then refine.

Intelligent Editing & Refinement Tools

Beyond initial generation, SoloTools offers powerful, section-level AI editing commands. For any part of the proposal—be it the executive summary or scope of work—you can instruct the AI to "Make more persuasive," "Make shorter," "Make more detailed," or "Rewrite in formal tone." This allows for rapid iteration and fine-tuning to perfectly match your client's expectations and your personal voice without manual rewriting.

Complete Client Engagement Suite

SoloTools manages the entire client interaction post-creation. You can send proposals directly via email with a personalized message, set expiry dates to create urgency, and collect legally-binding e-signatures where clients can draw their signature directly in the platform. The system also includes automated follow-up reminders, helping you nudge clients without sending awkward manual emails, and tracks the entire journey from sent to signed.

Proposal Analytics & Tracking

Gain valuable insights into your business development process. SoloTools provides real-time notifications the moment a client opens your proposal for the first time. You can view a conversion funnel (Sent, Viewed, Accepted/Declined) to identify where deals are being lost. This data, including win rates and average close times, empowers you to understand what's working and optimize your approach for winning more business.
