BLAISE Pro

Quotes, invoices, and client signatures for construction professionals, freelancers, and independent contractors. Mobile.

You know the drill. The client calls for a quote. You jot it down in a notebook, tell them, "I'll send it to you tonight." That evening, you come home exhausted, open Word, struggle with the legal disclaimers, and send it. Three days later, the client has signed with a competitor.

BLAISE Pro takes your quotes and invoices off the job site, not out of your kitchen.

What the app does in practice:

✓ Quotes and invoices in under 3 minutes, directly from your phone
✓ Client signature with a simple touch, directly on your screen
✓ Automatic conversion of the signed quote into an invoice
✓ Sending the PDF to the client by email, on-site
✓ Integrated SIRENE client search (SIRET number, address, legal structure are automatically filled in)
✓ Catalog of reusable items (hourly rate, square meter rate, flat rate, 25 kg bag of plaster)

Complete Construction Mode:

✓ Subcontracting reverse charge
✓ 5% retention money
✓ Reduced VAT rates of 5.5% and 10% (renovation, energy)
✓ Progress billing (percentage of completion)
✓ Automatic construction legal notices

Overseas Territories:

The app natively handles the VAT rates of the French overseas departments (Guadeloupe, Martinique, French Guiana, Réunion, Mayotte). You invoice with the correct rates right from the start, with no adjustments required.

Factur-X Compliance:

E-invoicing becomes mandatory in France for B2B transactions starting in 2026. BLAISE Pro generates your invoices in the SUPER PDP-validated Factur-X format. You'll be compliant the day it becomes mandatory.

Offline, Anywhere:

The app works even in areas with no network coverage. Create your quote in a cellar, basement, or at the bottom of a garden with no network. Everything synchronizes when you regain connection.

Your Data:

Local encrypted backup in .blaise format. Export it whenever you want and restore it to a new device in 30 seconds. No one but you can access it.

Who is it for?

Masons, painters, plumbers, electricians, landscapers, pool builders, carpenters, tilers. Self-employed individuals, micro-entrepreneurs, sole traders. All those tradespeople who invoice from the field and are tired of juggling Excel, Word, and their own memory.

The publisher:

BLAISE Pro is published by BP Software, based in Apt (Vaucluse, France). Pascal, the founder, is a computer scientist by training. Ten years ago, he retrained in the wood construction industry and spent a decade creating quotes and invoices from the job site. The app wasn't coded by a developer who discovered tradespeople through market research: Pascal knows how to code, and he experienced the need firsthand for ten years. He's the one who answers support emails.

Upon installation, you create your first quote in 3 minutes. No forced registration, no credit card required.

The next client who asks you for a quote? They'll sign before you even leave the job site.
