Built for Trade Speed.
Engineered to Get You Paid.
Two breakthrough features designed for boots-on-the-ground contractors that legacy invoicing tools completely overlook.
Type Once, Recall Forever™
Type any custom trade job, labor charge, or specialty fixture once. DoXMitra stores it in your private catalog, ranked by frequency. Next time you're on the job site, type two letters to populate the full line item from an instant dropdown.
Velocity Vanguard™ Copilot
Your revenue copilot and target pacer. It tracks your monthly target, spots past clients due for seasonal maintenance, and queues pre-filled WhatsApp follow-ups with one tap.
Triggered automatically 180 days after their April invoice: 3 commercial clients are due for their 6-month periodic heating & compressor checkup based on your configured service interval. (Sample preview)

Frequently Asked Questions
Everything you need to know about contractor invoicing, receipts, and tax compliance.
An estimate is a non-binding proposal of costs provided before work begins. An invoice is a formal request for payment issued after parts are delivered or services are rendered. A receipt is the final proof that payment has been made in full. All three are standard commercial documents used for record-keeping and tax purposes.
It depends entirely on your region and the type of work. In many US states, labor for residential repair is non-taxable, while commercial repair labor is taxable. However, tangible materials and fixtures are almost always taxable. DoXMitra applies the standard rates for your selected location — always verify the correct treatment with a local tax advisor for your specific situation.
Word and Excel require manual tax calculations, lack professional styling, and don't maintain a centralized record. DoXMitra is purpose-built for tradespeople, meaning it knows the exact line items you need and applies statutory tax rates automatically, exporting a clean, print-ready PDF in seconds.
Yes. DoXMitra offers 100% free, unlimited PDF document generation without any watermarks or forced branding. We believe fundamental business tools should be accessible to every tradesperson.
When filled out with accurate business information, client details, and itemized services, the PDFs generated by DoXMitra are standard commercial documents suitable for record-keeping, invoicing, and tax filing. Legal sufficiency depends on your jurisdiction and specific transaction — always verify requirements with your local tax advisor or accountant.
