Feature Comparison
Invoice Guru
Mobile-First Invoice Creation
This core feature is built for speed and efficiency on the go. Users can generate a complete, professional invoice in less than 60 seconds directly from their mobile device. The process involves entering client details and job items quickly, with automatic inclusion of your logo, company information, VAT, and payment terms. This eliminates the need to return to the office or use a computer, enabling immediate invoicing as soon as a job is completed.
AI-Powered OCR Receipt Scanner
This feature automates expense tracking to save hours of manual data entry. By simply taking a photo of a paper receipt with the app's camera, the built-in Artificial Intelligence (OCR) technology reads all the key details such as date, vendor, amount, and tax. It then automatically creates a categorized expense entry within the system. This ensures accurate record-keeping for tax purposes and provides a clear view of business spending without manual input.
Automated Bank Integration & Payment Matching
Invoice Guru streamlines payment tracking by securely connecting to your business bank account. Once linked, the software automatically imports new transactions and intelligently matches them against your outstanding invoices. This reconciliation happens automatically, showing you instantly which clients have paid and clearly highlighting any overdue payments, giving you a real-time view of your cash flow.
Multi-Language, Multi-Currency & Tax Compliance
Designed for both local and international work, this feature supports business growth. It allows you to create invoices in over 12 languages and multiple currencies, catering to a diverse client base. Fundamentally, it ensures your invoices are 100% compliant with local tax regulations, including automatic submissions for UK MTD VAT and compatibility with Poland's KSeF system, providing peace of mind and legal security.
SoloTools
AI-Powered Proposal Generation
The core feature of SoloTools is its intelligent AI engine. It does far more than fill in templates. Based on the brief project details you provide, the AI writes a compelling, tailored proposal from the ground up. It crafts persuasive executive summaries, breaks down the scope of work into clear phases, structures professional pricing tables, and outlines project timelines and terms. This ensures every proposal is client-ready, coherent, and professionally formatted without any manual writing effort.
AI Section-Level Editing
After the AI generates your proposal, you retain full control with smart editing tools. For any section of the proposal, such as the executive summary or scope, you can instruct the AI to refine the text on the spot. You can use simple commands like "Make more persuasive," "Make shorter," "Make more detailed," or "Rewrite in formal tone." This allows for quick, intelligent customization without having to manually rewrite entire paragraphs, saving even more time while perfecting the message.
Client Tracking & E-Signatures
SoloTools manages the entire client interaction after the proposal is created. You can send proposals directly to clients via email with a personalized message. The platform then provides real-time analytics, notifying you the moment a client opens your proposal for the first time. Most importantly, it includes a built-in canvas for clients to provide legally-binding e-signatures directly on the document, streamlining the acceptance process and eliminating the need for separate signing software.
Proposal Analytics & Automation
This feature provides valuable insights into your business performance. You can view a clear conversion funnel showing how many proposals were sent, viewed, accepted, or declined. This helps you understand your win rate and identify where you might be losing deals. Furthermore, the tool offers automation like automatic follow-up reminder emails (set for 3, 5, or 7 days) and the ability to set proposal expiry dates to create urgency, helping you manage the follow-up process without manual effort.
Use Cases
Invoice Guru
For On-Site Tradespeople
A plumber finishing a repair can immediately create and email a professional invoice to the homeowner from their van using their phone. They add parts used and labour, apply VAT, and send it before leaving the property. This speeds up payment, improves cash flow, and presents a highly professional image without any paperwork.
For Small Service Business Owners
The owner of a small decorating company can manage all client quotes and invoices from one mobile app. They can generate quotes during initial consultations, convert them to invoices once the job is approved, and track which invoices are viewed and paid. This centralizes their administrative work and provides clear oversight of all jobs and finances.
For Expense and Receipt Management
A self-employed electrician can use the OCR scanner to photograph all receipts for materials bought throughout the day (wire, fittings, fuel). The AI extracts the data, categorizes each expense, and stores them digitally. At tax time, all expenses are perfectly organized for their accountant, saving evenings spent sorting through paper receipts.
For Ensuring HMRC MTD Compliance
A UK-based tradesperson who is VAT-registered can use Invoice Guru to meet their Making Tax Digital obligations without needing separate software. They record all sales (invoices) and purchases (scanned receipts) digitally in the app, and can submit their VAT return directly to HMRC through the software, ensuring they remain compliant with the law.
SoloTools
Freelance Web Designers & Developers
For freelancers building websites or applications, SoloTools is ideal for quickly proposing projects. By inputting the client's name, project type (e.g., "Website Redesign"), budget, and key requirements, the AI generates a detailed proposal complete with phases like Discovery, UI/UX Design, and Development, including timelines and pricing. This allows designers and developers to respond to client inquiries rapidly and professionally.
Independent Marketing & SEO Consultants
Marketing consultants can use SoloTools to propose campaigns, SEO audits, or content strategy projects. The AI can structure proposals that outline objectives, key performance indicators, service packages, and investment summaries. The ability to track when a client views the proposal is particularly useful in fast-paced marketing discussions, allowing for timely follow-up.
Business & Management Consultants
Independent consultants offering strategic advice can leverage SoloTools to formalize their engagement terms. The AI helps draft a clear scope of work, methodology, deliverables, and a professional fee structure. The e-signature feature ensures the consulting agreement is executed smoothly, providing a clear record for both parties.
Creative Professionals (Writers, Designers, Videographers)
Freelancers in creative fields often need to propose fixed-price projects for specific deliverables like a video series, a branding package, or a set of articles. SoloTools enables them to convert a project brief into a formal proposal with itemized costs for each deliverable, a clear timeline for revisions and final delivery, and standard copyright or usage terms, presenting their creative work as a serious business service.
