Problems

What's costing you time and money every week

📝

Quotes and invoices eating your time

Each quote takes 30 to 45 minutes. Reminders are done manually. Calculation errors go unnoticed. Result: hours wasted and margins eaten away.

🕒

Timesheets on paper

Your employees jot down their hours on loose sheets. At the end of each month, you copy everything into Excel for the accountant. Hours wasted on re-entry, payroll errors, and no visibility on job profitability.

📦

Stock managed by gut feeling

You order when you run out, you don't know what's left in the van or the warehouse. Result: shortages that delay jobs, or overstock gathering dust.

🙈

Mandatory e-invoicing

Electronic invoicing is becoming mandatory for all businesses. Factur-X formats, submission through the public portal — if you're not ready, you face penalties and payment delays.

Already using a trade software?

Batigest, EBP, ProGBat, Codial — you've hit the ceiling of your current software

You invested in a trade software and it served you well. But as your business grows — more job sites, more employees, more clients — it turns from accelerator into bottleneck.

📱

Not built for the field

Your employees log hours and job site photos from a desktop PC at the office, never from mobile. Result: double entry, delays, missed data. Your tools are stuck in 2010 while your teams live on smartphones.

🔒

Impossible to adapt to your trade

Your quoting process, your job site breakdown, your margin tracking — every tradesperson has their own way. Vendors offer their standard workflow only. Customizing it costs a fortune or gets refused outright.

📈

Your growth is plateauing

You want to launch a second team, track profitability by job type, integrate a CRM, automate reminders. But your software connects to nothing, its reports are rigid, and every change costs months and thousands of euros.

Our approach: we build custom exactly what your current tool will never do. No painful replacement — we extend, we connect, we automate what's holding you back.

Solution

A management tool that gives you full control

We build custom tools for tradespeople: automatic quote and invoice generation, real-time job site tracking, stock and hours traceability. Everything centralized, accessible from your phone or desk.

Result: less time on admin, immediate visibility on which jobs are profitable, and your team always knows where every project stands. You run your business on real numbers.

Client case

César Peinture

Building painting — Brittany, France

Before, timesheets were on paper. At the end of each month, I had to copy everything into Excel for the accountant. Today, my 4 employees log their hours directly, stock is tracked in real time, and the accounting export is one click away.

FAQ

Frequently asked questions

Is my business affected by mandatory e-invoicing?

If you're subject to VAT in France, yes. The obligation to receive electronic invoices applies from September 2026. Issuing becomes mandatory in September 2027 for SMEs and small businesses. Better to prepare now than rush later.

How long does it take to set up a management tool?

A targeted management tool (timesheets, stock, invoicing) can be operational in 1 to 3 months. We start with your most costly pain points and evolve the tool over time.

I only have a few employees, is it worth it?

That's exactly where the gains are most visible. The fewer people you have, the more admin time weighs on everyone. Automating invoicing and timesheets means recovering hours every week — even with just 4 people.
