Izi-Devis provides AI-powered estimating and invoicing software designed for tradespeople and small construction businesses. Users can dictate or type a job description on a phone or computer, and its assistant, Izou, organizes the client details, work items, quantities, pricing, taxes and required legal information into a professional quote. Documents use the user’s own service and materials prices, with applicable VAT calculated for each line. Customers can approve quotes online without creating an account, and a signed quote can be converted into an invoice with any deposit deducted.

The service also supports invoices, progress invoices and credit notes, payment reminders, and a dashboard that highlights follow-up tasks. Email reminders are sent only after the user confirms them. Izi-Devis says it prepares invoices for upcoming French e-invoicing requirements, including Factur-X and e-reporting. Its tools are aimed at trades such as plumbing, electrical work, painting, masonry, tiling, carpentry, heating and landscaping. The site offers a free first month with no commitment and describes a Pro plan feature for viewing jobs on a map.
