Invoice Guru is a mobile-first invoicing app built specifically for tradespeople and small service businesses. Most invoicing tools are designed for desktops and office work. Invoice Guru is built for people who work on-site — painters, plumbers, electricians, and other trades — who need to create and send invoices quickly from their phone. The app focuses on speed, simplicity, and real-world automation. Users can create invoices in seconds, track payments, and reduce admin work with features like automatic accountant reports, bank integration with payment matching, and OCR receipt scanning for expenses. Invoice Guru is designed with upcoming regulations in mind, including UK MTD and Poland’s KSeF, so users don’t need to switch tools when compliance rules change. The product is built by a tradesperson who understands the day-to-day challenges of running a small business, not by a desktop-first accounting company.
