What we do

Websites & mobile apps

Custom digital solutions, from design to deployment.

Everything we offer

One agency, six ways to help you: pick the one that matches your project, or describe your need and we will find the right form together.

Custom websites

EUR 1,000 for a showcase site, EUR 1,500 to 4,500 with features

A showcase site delivered fast and well, or an elaborate site matching exactly what you wanted, with or without a back office to manage your content. Fast, findable on Google town by town, readable by AI assistants.

Ready-to-go sites by trade

EUR 1,500 to 3,500 depending on the trade

We studied a trade, built all its features, and offer them to every professional in it: real estate agency, pizzeria and takeaway, emergency repairs, cleaning, landscaping. The design is recreated for each client.

iOS and Android mobile apps

EUR 2,000 for a showcase app, EUR 4,500 with features

With or without a back office, with or without an associated showcase site. We take care of logic, design, features and future evolutions, and we handle publication on the App Store and Play Store.

Custom software and back offices

On quote, after the first conversation

Software built only for you, applied to your trade: quotes, automatic invoices, customer file, payment tracking, forecasts. Or a complete platform (app, site, back office) from EUR 12,000 to 75,000.

Search optimisation: the guide, the software, the support

SEO INTERACT EUR 25 per month; support EUR 250 per month for six months, then EUR 200

The public guide in 25 elements explains how a site gets found. To go faster: SEO INTERACT, the software to do it yourself (coming soon), or the support to hand it over.

Support after delivery

Complimentary, 1 to 6 months depending on the project

Once the project is live, you are not left alone: small changes, tweaks, questions, unexpected issues, with the same contact. The duration is set in the quote, extendable, never shortened. For quoted projects, support is defined in the quote.

How a project unfolds

Everything starts with a twenty to thirty minute call, by video or phone. We listen to the business need before discussing technology: who will use the tool, for which task, and what success looks like six months from now. That conversation leads to an itemised quote within 48 hours. A written specification is not required to start, though a few scoping notes noticeably cut down the back and forth on pricing.

Design comes next. Before the first line of code, we draw the key screens and the navigation logic, so you approve mockups rather than promises. This is the cheapest moment to change your mind: moving a button on a mockup takes minutes, while the same change after development costs a day.

Development then moves in functional batches. You receive a testable build, openable on your own phone or browser, within the first weeks: no tunnel effect, no big reveal on the last day. Depending on the project, the interface runs on React or React Native, the server on Node.js with a PostgreSQL database. Connections to third-party software, such as a payment gateway or a business tool, are quoted separately because each one carries its own rules and failure cases.

Release closes the cycle. We publish the site, or submit the application to the App Store and Play Store, handling listings, screenshots and store review, then we train whoever will manage the content. Maintenance afterwards is not a decorative extra: mobile operating systems change twice a year, and an app left without updates eventually gets removed from the stores.

What every project includes

  • Full ownership of the result: on delivery and full payment, the source code is yours, with no licence to renew and no lock-in to our studio.
  • A clean technical structure, readable by browsers, search engines and conversational assistants alike. This technical quality is part of the price of the site. To go further, our search optimisation guide is public, and two options exist: the SEO INTERACT software to do it yourself, or our support to hand it over.
  • Careful rendering on phone, tablet and desktop, tested on real devices rather than in a simulator only.
  • Written commitments on deadlines, confidentiality and data hosting inside the European Union.

These four families of work are the whole of what we do, and the studio in one page gives the shortest overview of them.

Price ranges by project type are published on our pricing page, delivered work is described in our portfolio, and the people behind the studio are introduced on the about page. When the scope is clear enough, describe your project and you will get a quote within 48 hours.
