More importantly, it's built to keep you compliant, with built-in readiness for key regulations like HMRC's Making Tax Digital (MTD) in the UK, ensuring your submissions are correct and hassle-free.
SoloTools
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.

Frequently Asked Questions
Invoice Guru FAQ
Is Invoice Guru really free to start?
Yes! Invoice Guru offers a Free Forever Starter Plan that allows you to create up to 10 invoices, download them as PDFs, and use basic features. This is perfect for trying out the app or for very small businesses to manage their core invoicing needs at no cost.
How does the AI receipt scanner work?
It's very simple. You just open the app and take a photo of any paper receipt. Our advanced Optical Character Recognition (OCR) technology then automatically reads the text on the receipt, extracts key details like the date, vendor name, and total amount, and creates a digital expense entry in your account. You just confirm the details, and you're done!
Is my financial data safe with Invoice Guru?
Absolutely. Security is a top priority. We use bank-level encryption to protect all your data. Our bank integrations are provided by secure, regulated third-party providers (like Plaid in the UK) that never share your login credentials with us. Your information is always safe and private.
Can I use Invoice Guru for Making Tax Digital (MTD) in the UK?
Yes, you can. The Pro Plan includes features that support MTD for VAT compliance. It helps you keep digital records and can facilitate the submission of your VAT returns directly to HMRC through our MTD-compatible platform, making the entire process much smoother.
SoloTools FAQ
Is there really a free plan?
Yes! SoloTools offers a completely free plan that requires no credit card to start. You can create and send up to 3 full proposals every month at no cost. This includes AI generation, editing, and sharing via link. It's a perfect way to test the tool and see how much time it can save you on your next client pitch.
How does the AI know what to write in the proposal?
The AI is trained on thousands of successful business proposals. When you input your project details—like client name, project type, budget, and scope notes—it uses this context to generate relevant content. It structures industry-standard sections and uses persuasive language tailored to your specific service, ensuring the proposal is both professional and personalized.
Can I edit the proposals the AI creates?
Absolutely. Every part of the AI-generated proposal is fully editable. You can click into any text box and change the wording directly. More powerfully, you can use the AI editing commands per section (like "Make more persuasive") to refine the content without manually rewriting everything, giving you total creative control.
Are the e-signatures legally binding?
Yes, the electronic signatures collected through SoloTools are legally binding. The system creates a clear audit trail that records the client's signature action, their IP address, and a timestamp. This provides a valid record of their intent to accept the proposal and its terms, which is recognized for most business contracts and agreements.
