Invoice Guru is a mobile-first invoicing app built for small businesses, freelancers, and tradespeople who want to get paid faster — without wrestling with complex accounting software.

The product is designed around three core principles: speed, simplicity, and compliance. Creating, sending, and managing invoices should take seconds, not minutes, while still meeting country-specific tax and e-invoicing requirements.

Invoice Guru is built for real-world use: on-site, on the phone, between jobs.

Who it’s built for

Invoice Guru is ideal for:

• Small business owners

• Freelancers

• Tradespeople (plumbers, electricians, painters, contractors)

• Anyone who needs compliant invoicing without full accounting software

Why Invoice Guru exists

Most invoicing tools fall into one of two extremes:

• Over-engineered accounting systems that are slow and confusing

• Over-simplified tools that break once compliance becomes mandatory

Invoice Guru sits in the middle:
simple enough for daily use, serious enough for regulations.

The long-term vision is to build a single, mobile-first invoicing platform that works across multiple countries, adapts to local rules automatically, and helps small businesses focus on getting paid — not managing software.
