Custom development: back offices, client portals, integrations

When no-code isn’t enough, we build the tool you need: a back office designed around your trade, a portal for your clients, an integration between pieces of software that refuse to talk to each other. Fixed price, with the team that ran the audit.

Off-the-shelf tools cover most of what a small business needs. The rest is where you lose time: the spreadsheet that stood in for proper software, the double entry between your business software and your accounting, the clients who call to ask how their file is going.

Custom development takes care of the rest. We build lean, fast web applications hosted in Europe, designed to last and to evolve. And because it’s the same developers from start to finish, you only have to explain your business once.

Who it’s for

  • 01

    Your business runs on a spreadsheet that has hit its limits.

  • 02

    Your clients or partners are asking for a space where they can follow their files, orders or documents.

  • 03

    Two pieces of software you can’t do without don’t talk to each other, and someone re-enters data between them.

  • 04

    You have a no-code tool that grew too fast and is becoming fragile.

What’s included

  • Business back office

    An internal application to manage your files, schedules, stock or quotes, with your rules and nothing superfluous.

  • Client or partner portal

    A secure space where your clients follow progress, upload documents, sign or pay. Fewer calls, fewer emails.

  • Complex integrations

    Connecting your business software, your accounting, your bank or a platform without a proper API. Reliable syncing, errors flagged.

  • Built-in AI where it makes sense

    Document extraction, search across your data, text generation. Inside the tool, not off to the side.

How it works

  1. 01

    Functional scoping

    Together we write down what the tool must do, screen by screen, including edge cases. This is the document that sets the price.

  2. 02

    Fixed-price quote

    A firm price, a timeline, milestones. No billing by the hour, no surprises.

  3. 03

    Built in stages

    You see a usable version every two weeks. You test it on your real cases, and we adjust before going further.

  4. 04

    Delivery and handover

    Source code, documentation, hosting in your name. You own what we built.

What you walk away with

  • A web application in production, hosted in Europe, accessible from any browser
  • The source code and technical documentation, in your name
  • GDPR compliance built in: access rights, logging, retention periods
  • A maintenance plan for future changes, if you want one

Frequently asked questions

How much does custom development cost?

On quote, at a fixed price. The price depends on the number of screens, the integrations and the business rules. It is set after functional scoping, before the first line of code, and it doesn’t change along the way.

Why not a no-code tool?

Often, that’s the right call. When an existing tool or an automation is enough, we tell you, because it’s cheaper. Custom development makes sense when the business rules are specific, when volume grows, or when reliability and data ownership matter.

Which technologies do you use?

Standard, proven web technologies that another developer could easily take over if you ever want them to. European hosting. We specify them in the quote.

Who owns the code?

You do. The source code and access are in your name from delivery.

Shall we talk?
