About DoxMitra — The Free Receipt & Invoice Generator Built for Contractors
DoxMitra is the free receipt generator, invoice maker, and estimate builder built exclusively for plumbers, electricians, HVAC technicians, handymen, painters, roofers, locksmiths, and every trade that keeps homes and businesses running. We started with a simple idea: contractors shouldn't need an accounting degree to create a professional, tax-compliant receipt in under 60 seconds.
Why We Built DoxMitra
Every day, millions of tradespeople finish a job and then waste 20 minutes wrestling with Word templates, Google Docs, or overpriced accounting software just to hand their customer a receipt. We watched plumbers in Texas struggle to calculate state sales tax. We saw electricians in California guess at district tax rates. We heard HVAC techs in Ontario ask whether to charge HST or GST. And we noticed contractors in India manually typing HSN codes into Excel sheets.
So we built something better.
DoxMitra is a free online receipt generator that understands your trade, your region, and your tax rules. Whether you need a plumber receipt template for Texas, an electrician invoice with GST for India, a VAT-compliant invoice for UK tradesmen, or an HST estimate for Ontario HVAC, our tool auto-calculates the numbers, formats the document, and exports a clean PDF you can email or print on the spot.
Who We Serve
We built DoxMitra for the self-employed contractor and the small trade business — the folks who wear the tool belt and run the back office.
