What is Donizo?

Donizo is quoting and invoicing software for the building trades: plumbers, electricians, painters and more. Describe the job by voice from your phone: Donizo structures the line items, applies the right VAT rate and hands back a send-ready PDF quote in about thirty seconds.

Your customer signs online, the invoice follows in Factur-X format, mandatory for French professionals since September 2026, and payment reminders go out without you chasing them. 7 days free, no card required.

Quotes, invoicing and payments, all in one place.

Adrien Ragiot, founder of Donizo

Built by someone who came up on site

Adrien Ragiot came up in the trade. As a plumber, he spent his days on site. Back then his best friend worked for himself. An excellent plumber, sunk by the paperwork.

He built Donizo so that good tradespeople stop going under because of admin. He is one of them, and he knows what this craft deserves. Now the admin is automatic and optimized, and the tradesperson stays on the craft.
