Custom development
Portals, web applications and features specific to your business, built from scratch.
When custom is the answer
Custom development means designing a web application or portal from scratch when no CMS or off-the-shelf software covers your needs: client area, extranet, management tool, calculator, business platform connected to your data. Our developers work in PHP (Laravel, Symfony) and JavaScript (React, Vue, Node), with clear specifications, two-week sprints and code that belongs to you.
Custom or CMS: how to decide?
A presentation website or a standard shop works very well with WordPress or Prestashop: see showcase website design or e-commerce website design. Custom development is the answer when your value lies in a specific process: complex quote calculation, file management, booking with business rules, data dashboard, an application used daily by your customers or staff. In that case, bending a CMS costs more in the long run than building properly.
What we build
- Business web applications: back-offices, dashboards, management tools, approval workflows.
- Portals and extranets: client, partner or staff areas with secure access and roles.
- APIs and integrations: connecting your tools, CRM, ERP, payment, logistics, electronic signature.
- Mobile applications for iOS and Android with React Native or Flutter, sharing your web application’s API.
- Legacy application takeover: migration to current technologies without service interruption.

Our method
- Scoping: workshops, functional and technical specifications, costing per batch. The initial workshop is free.
- Design: UX/UI mock-ups by our designers, architecture, technical choices.
- Development: two-week sprints, demo at every delivery, automated tests, code review.
- Go-live: deployment, training, documentation, three-month warranty then ongoing maintenance.
Technologies and best practices
PHP 8 with Laravel or Symfony, JavaScript with React, Vue or Node, MySQL and PostgreSQL databases, Docker containers, continuous integration, cloud hosting in Europe. Code versioned on Git, documented and tested: you can take it in-house at any time. Security: strong authentication, encryption, protection against common attacks, GDPR compliance.
Budget and timelines
The budget depends on scope. A simple client portal starts at around €6,000, a complete business application at around €15,000 and up. We quote per functional batch after the scoping workshop, with a realistic schedule: allow six weeks to several months depending on ambition. Our offshore rates deliver European-quality development at a controlled cost. We also work on a time and materials basis if you prefer to manage development yourself.
