ATTIX – Devis & factures BTP

Benoit LAHAYE

About this app

The leading software for the construction industry. Quotes and invoices, reinvented by AI. On your phone or computer.

ATTIX is the ONLY software that generates a COMPLETE quote by voice, from the job site to the invoice, while adhering to French building standards (DTU).

ATTIX was born from a simple observation: construction managers spend too much time on administrative tasks instead of running their business. Hours wasted every week on quotes, invoices, and data re-entry. ATTIX was built to make management a competitive advantage, not a burden.

Your entire project lifecycle, in one place
Manage your projects from start to finish: quotes, work packages, variations, invoices, amendments, and credit notes. Everything remains linked to your project, from the initial quote to payment. Electronic signatures are integrated to validate your quotes online, without re-entering data.

The quote, designed like a professional's quote
Describe the project. Whether by voice, photo, or keyboard, ATTIX builds the quote based on the actual workflow: the right steps, the right supplies, the right quantities, all in compliance with DTU standards. Variations, options, VAT, electronic signature: the client signs on-site, and you leave with an accepted quote.

Software that learns your workflow
Your previous quotes are analyzed, your prices imported, your methods learned, and your library built. The more you use it, the more it reflects your style.
What sets ATTIX apart isn't having a microphone. It's that the quote it generates is truly yours: your prices, your breakdown, your VAT, ready to sign and already linked to the subsequent invoice.

The most comprehensive invoicing on the market
Down payments, progress reports, interim invoices, balances, credit notes. From the first invoice to the last, the entire financial lifecycle of your project. Integrated Factur-X and Peppol, compliant with 2026 regulations.

Why ATTIX?
The simplest: all the power of construction software, without the complexity. No training required.
The smartest: learns your workflow, integrates your supplies, and updates your pricing.
The most technical: integrated DTU standards, invoicing for deposits, progress payments, and final balances, automatic mixed VAT.
The most mobile: accessible via the app on the job site and via the web application in the office. Always synchronized.

For all construction trades
Roofers, masons, drywallers, electricians, painters, carpenters, plumbers: ATTIX speaks your vocabulary, understands your units, and respects your rules. Designed for freelancers and SME managers alike.
