Invoice Guru

60-Second Invoice Creation

This is the flagship feature and it delivers exactly what it promises. With a mobile-first interface designed for thumbs, you can generate a professional, branded invoice with your logo, VAT, and payment terms in under a minute. It eliminates the clunky, multi-step processes of other apps, letting you get back to your job instantly. The automatic numbering and dating based on your fiscal year settings are small touches that prevent big headaches.

AI-Powered OCR Receipt Scanner

This is a personal favorite and a massive time-saver. Simply snap a photo of a paper receipt with your phone, and Invoice Guru's AI instantly reads all the details—vendor, date, amount, tax—and logs it as a categorized expense. It completely eliminates manual data entry, turning a stack of crumpled receipts into organized records in seconds, making expense tracking and VAT reclaim effortless.

Smart Bank Integration & Payment Tracking

Stop cross-referencing bank statements with your invoice list. By securely connecting your business bank account, Invoice Guru automatically matches incoming payments to their corresponding unpaid invoices. It gives you a real-time, crystal-clear view of exactly who has paid and what's overdue, transforming your cash flow management from a monthly chore into an automated process.

Multi-Language, Multi-Currency & Compliance Ready

Built for modern, mobile businesses, Invoice Guru supports over a dozen languages and multiple currencies, perfect for tradespeople working with international clients or across borders. More importantly, it's engineered for compliance, with built-in readiness for major regulations like UK MTD for VAT submissions and Poland's KSeF e-invoicing, ensuring your business is always on the right side of the law.

PDF Compiler

Configurable Fields

PDF Compiler allows users to define a variety of fields in their documents, including text inputs, dates, variables, selections, and even Excel-style formulas. This flexibility ensures that all necessary data can be efficiently captured and managed, catering to the unique requirements of each project.

Minimal Input

One of the standout features of PDF Compiler is its ability to minimize user input. Users only need to enter essential data once, and the software automatically populates all linked documents with the appropriate information, adhering to the predefined configurations. This not only saves time but also reduces the likelihood of data entry errors.

Data Linking

With PDF Compiler, any updates made to a field automatically propagate across all PDFs within the project. This means that users can make changes to a single data point, and the software will ensure that all related documents reflect those updates, maintaining consistency and accuracy throughout the entire set.

Automated Workflows

The software enables users to generate complete document sets in mere minutes. With its dynamic calculations and formatting capabilities, PDF Compiler streamlines the entire process of document preparation, allowing users to compile all necessary forms instantly, ready for submission, sharing, or printing.

The On-Site Tradesperson

A plumber finishes a job and wants to get paid before leaving the client's home. Instead of writing a scrap of paper or promising to "send an email later," they open Invoice Guru on their phone. In under 60 seconds, they create a professional invoice, apply a QR code for instant payment via Stripe, and email it directly to the client. Payment is received before their tools are packed away.

The Small Service Business Owner

The bank integration reconciles payments automatically, freeing up their evenings and giving them peace of mind.
