- Scope and firm quote
I replace the SaaS tool you overpay for with a custom application at a fixed price. The first version is delivered within 2 to 4 weeks of build time, starting from a slot we agree on together. You own the code and the data. The investment typically pays for itself in 12 to 18 months.
AI-assisted development has changed the equation: a simple business application no longer takes months, but a few weeks.
Per-user pricing grows with your team, while the value of the tool stays the same.
Thanks to AI-assisted development and a proven technical base.
No SaaS fits the way you work, so workarounds pile up.
Price hikes, locked features, data that is hard to get out.
Agents connected to your data and approval workflows, billed as a flat fee plus actual usage.
Three typical cases with the calculator's figures, then one page per family of tools (in French). The screens are illustrative mock-ups: your application uses your fields, your steps and your words.
Your stages, your fields, your follow-up rules. No €40-per-person module of which you use a quarter.
Each request follows a defined path based on amount and department, with automatic reminders to the approver.
The technician fills it in on their phone: checklist, photos, client signature. The PDF goes to the office and the client straight away.
Typical cases built from the calculator's scenarios (maintenance and hosting €250/month). Build price includes the 40% launch discount. Indicative amounts in € excl. VAT, firm quote after the audit.
One example page per family of replaceable software: what you get back, what you save, how the migration works. (Pages in French.)
Contacts, pipeline, follow-ups and quotes, instead of HubSpot, Pipedrive or Zoho.
See the exampleTasks, boards, deadlines and reminders, instead of Asana, Monday, ClickUp or Trello.
See the exampleQuotes, invoices and payment reminders. Accounting stays with your accountant.
See the exampleBooking page, calendar and reminders, with no per-appointment commission.
See the exampleReal-time stock, threshold alerts, customer and supplier orders.
See the exampleTickets, shared inbox and canned replies, instead of Zendesk, Intercom or Freshdesk.
See the exampleConstruction, agencies, training, real estate… A line-of-business system built around your files, your fields and your steps.
See the exampleNo day rate, no surprises: each step has a written scope and a fixed price. Prices in € excl. VAT.
For the first four SMEs whose tool falls within my scope (confirmed in a 30-minute call) and who agree to have their case published (figures and name approved by you before anything goes online): free audit and 40% off the build. After that, regular pricing. In return: a demo every week, a testimonial and a case study. Maintenance stays at the regular rate. I take only a few projects a year, so I stay available throughout each one.
Out of scope: payroll, accounting, email, security tools and anything subject to heavy regulatory compliance.
Adjust your current subscription: you see the indicative price of a replacement, the break-even point and your savings over 3 years.
First version in 2 to 4 weeks, full handover in about 6 weeks. You see the application progress every week, and your old tool is only cancelled once the new one is approved.
Process, data export, scope and a written list of exclusions.
Days 1–2A demo every week; your feedback steers what comes next.
Weeks 1–4Migration, then the old and new tools run side by side.
2 weeksTraining, documentation, then cancellation of the SaaS.
DeliveryMonthly security updates, daily backups, reply within 2 business days.

General comparison: results vary by product and provider.
Code, data, continuity: it is all written in black and white in the contract.
Source code, documentation and access delivered. Common technologies (Next.js, Postgres): any developer can take over the project.
GDPR data processing agreement (DPA) provided. Your data stays in Europe.
Daily backups, monthly security updates, your requests handled within 2 business days.
No AI agent acts without explicit approval from your team.
You own the code, the data and the documentation. The stack is standard: any developer can take over the project without depending on us.
It guarantees a realistic scope and a firm price. Its cost is deducted from the build if you go ahead.
Yes, for the first 12 months: it protects your application (security, backups, fixes) and ensures follow-up.
A monthly allowance of hours for small changes is included. Beyond that, a short amendment sets out the scope and price before any development.
In France or the European Union, with daily backups. If you choose the AI assistant option, I state before the project where the data sent to the model is processed.
Typically a tool costing around €8,000/year or more, a per-user price across 15 or more people, or a process run in Excel and email. The price depends on the complexity of the tool to rebuild, not on the number of users: a simple tool pays off sooner, a complex one needs a higher current subscription.
You talk directly with the person who will build your tool: 30 minutes, no commitment, to list your subscriptions and see whether a replacement makes sense, or whether your current subscription remains the right choice.
