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.

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

A cleaning company owner spends hours every Sunday night doing admin: sorting receipts, chasing invoices, and preparing accounts. With Invoice Guru, they use the OCR scanner for receipts throughout the week and have automatic payment reminders chase late payers. The bank integration reconciles payments automatically, freeing up their evenings and giving them peace of mind.

The International Contractor

A UK-based builder regularly takes on projects in Europe. They need to invoice in Euros, comply with different local formats, and manage currency fluctuations. Invoice Guru allows them to create invoices in the local language and currency with correct tax settings, presenting a professional image and simplifying their cross-border accounting from a single, unified app.

The Accountant's Client

An accountant manages the books for several trade businesses. Their clients using Invoice Guru can grant them secure "accountant access." The accountant receives perfectly organized, automatic weekly reports summarizing all invoices, expenses, and scanned receipts, drastically reducing the time spent on data collection and entry and allowing them to focus on higher-value advisory work.

This is a mobile-first command centre built from the ground up for tradespeople and small service businesses. If you're a plumber, electrician, painter, cleaner, or builder, this tool was designed with your real-world workflow in mind.

The core promise is brutal, beautiful simplicity: create and send a professional, fully compliant invoice in under 60 seconds from your phone. But it doesn't stop there. Invoice Guru wraps in powerful automation like AI-powered receipt scanning and smart bank payment matching to eliminate hours of admin. Crucially, it's also future-proofed for key regulations like the UK's Making Tax Digital (MTD) and Poland's KSeF, so you're always compliant. This is the essential tool that finally bridges the gap between the skilled physical work you do and the digital paperwork you need to manage, all without needing an accounting degree to operate it. It’s not just software; it’s a productivity partner for your trade.

Can I use it for quotes and estimates as well?

Invoice Guru is a mobile-first invoicing app built specifically for UK tradespeople, designed to cut through the complexity of traditional accounting software. It belongs firmly in the category of job management and invoicing tools, but with a laser focus on the needs of service businesses and sole traders who work from their vans, not a desk. People look for alternatives for all sorts of reasons. Maybe they need a desktop-heavy workflow, require more advanced inventory management, or are simply shopping around based on price. Some businesses outgrow simple tools, while others find their needs are even more basic than what a dedicated app offers. When evaluating other options, your checklist should be clear: does it work seamlessly on a phone? Can it handle VAT and HMRC compliance without a headache? Will it save you time on admin, or just create more of it? The right tool should feel like a helpful apprentice, not a demanding foreman.
