Home/Services/Custom tools

The tool your company needs that doesn't exist on the market.

Internal managers, client portals, business calculators, operational panels. Software designed for your processes.

The problem

You've searched for commercial tools that fit your processes, but none of them does. Or they "almost" fit, and that "almost" forces you to change how you work to adapt to the software.

That makes no sense: software should adapt to you, not the other way around. Meanwhile, your team keeps getting by with spreadsheets, emails and manual processes they've already outgrown.

The solution: software that fits how you work

The exact tool your company needs. Not a generic product with features you don't use. A solution built for your processes, your team and your goals.

Accessible web apps

From any device with a browser. No installations, no manual updates. Your team accesses it from anywhere.

Internal tools

Project trackers, operations management, reporting tools. Designed for how your team works day to day.

Client portals

Your clients access their information, track their orders or interact with your company without relying on emails or calls.

Integrations with your systems

The new tool connects with what you already use. Without duplicating data, without copy-pasting between apps.

User-centered design

The tool is designed around the person who will use it every day. Clear interface, logical flows, minimal learning curve.

Your code from day one

The software belongs to your company. Documented, clean, without proprietary dependencies. If you want another team to maintain it in the future, they can.

Real example: internal management tool

A web app designed for a specific business process. Clean interface, clear flows and data accessible from any device.

Try a custom tool in action

The best way to understand the value of a custom tool is to use it. Here you'll get access to a working example to explore.

Interactive demo

Soon you'll be able to explore a working example tool here. In the meantime, I can analyze your case and show you what the solution would look like.

Expected results

What companies achieve when they move from generic solutions to custom tools.

100%

Adapted to how you work, not the other way around

Days

Working prototype to validate before committing

Yours

Documented code with no proprietary dependencies

A tool your team actually wants to use because it makes their work easier. More efficient processes, fewer errors, and the peace of mind that the software is yours and works exactly as you need.

Ballpark pricing

Every project is different, but these ranges give you a clear sense of the investment.

  • Business calculator
  • Smart form
  • Basic portal

Full project
€5,000 – €10,000
Price to be negotiated for the first 30
  • Multi-user platform
  • Complex business logic
  • Multiple integrations
Tell me about your case

The final price is set after a 30-minute conversation where I understand your case. No strings attached. Pay-per-use of external services (AI, deliveries, payment gateways, third-party APIs) isn't included: that's provider metering billed directly to the client, with a monthly cap if desired.

See in detail what's included and what's not

What's included

  • Process diagnosis and scoping meetings
  • Screen and interface design in Figma before development
  • Development with demos every 1-2 weeks
  • Database and backend (Supabase or similar)
  • User authentication and roles system
  • Initial deployment and configured domain
  • Technical documentation and user manual
  • Support during the first month

What's not included

  • Hosting: optional and separate (from €10/month depending on load) or on the client's own infrastructure
  • Third-party software licenses (Office, Adobe, etc.) if the case requires them
  • Pay-per-use for external APIs (AI, deliveries, payment gateways): billed directly to the client
  • Certifications (ISO, ENS): built to be able to pass them, but the audit is external
  • Maintenance from the second month (€15-60/month depending on complexity)
  • New features after delivery: handled as a new iteration

Common questions

"Custom development is much more expensive than buying a commercial tool."

It depends what you compare it to. If a commercial tool at €200/month doesn't solve your problem and your team keeps losing hours, the real cost is far higher than the monthly fee. A custom tool is paid for once and pays off every day it's used.

"What if I need changes later? I'm locked in with you."

The code is yours from day one. Documented, clean and without proprietary dependencies. If later you want another team to maintain it or to develop it internally, you can do so without restrictions.

"I'm not sure exactly what I need."

That's normal. My work starts by understanding your problem and your processes. From there I propose the solution. We start with a working prototype in days that you can test with real data before making any decision.

"Software projects always run long and over budget."

That happens when there's no prototyping or early validation. Here we work with short deliveries: prototype in days, validation with you, iteration. You see constant progress and if something isn't going the right way, we fix it fast and at minimal cost.
