A data model that fits
Your objects, your statuses, your rules. No field forced into a box it was not made for.
Business software
Custom software development Paris, code included
Business software built around your process instead of the other way round. Designed, developed and maintained in Paris, with the source code delivered to you.

The problem
When the spreadsheet quietly becomes the system
It starts as one file to track jobs. Three years later it has eleven tabs, four people editing copies of it, a macro nobody dares to touch, and a monthly figure that takes two days to rebuild. Off-the-shelf software did not fix it, because your process does not look like the one the software was written for, and the workaround became the process.
We develop the tool your work actually needs: quotes, jobs, planning, stock, invoicing, approvals, whatever the sequence happens to be in your business. We start from the real process, including the exceptions people handle by hand, and we build only what you ask for, in the order that helps you first. There is no per-seat subscription growing with every person you hire, and no module you pay for twice.
The software connects to what you already run, so figures are entered once and reconciled nowhere. You get a first usable version in weeks rather than at the end, then modules in your order of priority. At production you receive the source code, the database and the documentation, and you stay with us only for maintenance and new work.
What we build
The parts most projects need
Every project starts with a core, then grows module by module in your order of priority.
Documents and exports
Quotes, orders, invoices and reports in your own layout, plus CSV, Excel and PDF exports that accountants accept.
Automation
Scheduled jobs, reminders, escalations and status changes that fire on rules instead of on someone remembering.
Integrations
Accounting, payroll, e-commerce, telephony or machines on the shop floor, linked through APIs, files or webhooks.
Dashboards
The figures you rebuild by hand today, live: margin, load, delays, activity per team and per period.
Roles and audit trail
Each person sees their scope and nothing else, and every change is logged with who, when and what.
How we work
How a software project runs
Four stages, in this order. You sign off each one before the next starts.
- 1
Scoping
A day with the people who do the work, to map the real process rather than the manual. Deliverable: a priced, prioritised scope.
1 to 3 weeks - 2
Mockups and sign-off
Clickable screens for each path through the tool. You correct the mockup, where correcting is free.
2 to 3 weeks - 3
Development in batches
A testable delivery every two weeks, in your order of priority. You use the core while we build the rest.
8 to 16 weeks - 4
Migration and go-live
Existing data imported, teams trained, then maintenance and new modules. The source code is yours.
Ongoing

Job tracking for a field maintenance company
The same job was entered three times: once on a paper ticket, once in a planning spreadsheet, once in the invoicing software. We built a single job record from the call to the invoice, with the schedule and the accounting export attached to it.

Budget
What custom software costs
The figure depends on the number of modules and on the integrations. Here is the usual starting point.
Software project — from
9 000 €
Indicative figure for a standard scope. Every quote is issued as a fixed price after the scoping phase, with no per-seat fee.
- Scoping and mockups included
- Hosting and go-live
- Data migration and training
- Source code delivered, no lock-in
How it is priced
Software is priced after scoping, not before
Two companies in the same trade never quite run the same process. We look at yours first — including the exceptions your team handles by hand — and then we put a fixed price on what actually has to be built.

After delivery
Maintenance is priced with the project
Business software keeps living: regulations change, your other tools change, your team asks for adjustments. The contract is drawn up alongside the quote, and it can be cancelled.

FAQ
What people ask us most
Is custom software not more expensive than a subscription?
It costs more on day one and less over five years, because there is no per-seat fee growing with the team. The honest test is simple: if a standard product fits your process without workarounds, buy it. We will tell you when that is the case rather than sell you a project.
How soon can our team use something?
A first usable version normally lands eight to ten weeks in. Your team works on the core while we build the remaining modules, which also means the feedback that changes the design arrives early, when changing it is still cheap rather than after everything has been written.
Can it replace only part of our current tools?
Often that is the better plan. We frequently keep the accounting or payroll software in place and build only the missing layer around it, connected through an API or a scheduled export. Replacing everything at once is rarely worth the risk when one weak link is the actual problem.
What happens if we stop working with you?
You keep the source code, the database and the documentation, and the software goes on running. Any competent development team can take it over, which is exactly why we write it with standard tools instead of a framework only we know. We help with the handover if you ask.
