CUSTOM

Custom Development

WHEN CMS SOLUTIONS
ARE NOT ENOUGH,
WE CODE YOUR SOLUTION.

Your project outgrows the limits of WordPress, Webflow or Shopify. You need a SaaS platform, a client portal, a business dashboard, a marketplace or a complex web application. That is where custom development makes all the difference. We design and develop web solutions tailored to your specific needs, with the most modern technologies on the market. React and Next.js for fast and reactive interfaces. Node.js and Python for robust backends. APIs that connect your tools together. An architecture designed to scale with your growth. No technical limits, no functional compromises — just the exact solution your business needs.

The problem

THE LIMITS HOLDING BACK YOUR GROWTH

When your business outgrows the capabilities of a CMS, it is time to go custom.

block

Your CMS is holding you back

You spend more time working around your CMS limitations than growing your business. The plugins do not do exactly what you need, the workflows are clunky, and every new feature is a hack. Custom development eliminates these constraints: every feature is built to precisely match your business processes.

trending_up

Your platform does not scale

Your website crashes when traffic increases. Your database slows down with volume. Your architecture was not designed for growth. A custom application is architected from the start to absorb increased load. Microservices, caching, CDN, load balancing — everything is designed so your platform grows with your business.

integration_instructions

Your tools do not communicate

Your CRM, your ERP, your invoicing tool, your support platform — each lives in its own silo. Data is entered twice, errors multiply, and nobody has a complete overview. Custom development connects all your tools via API. A single ecosystem, synchronized data, tenfold efficiency.

speed

Performance is mediocre

CMS platforms generate generic code to cover every use case. The result: heavy pages, unnecessary database queries, and load times that frustrate your users. Custom code contains only what your application needs. Every query is optimized, every component is performant.

Our process

HOW WE DEVELOP YOUR CUSTOM SOLUTION

An agile process with incremental deliveries. You see progress at each sprint.

Discovery & Specs

Scoping workshops to understand your business processes, users and objectives. We write the functional and technical specifications. Solution architecture, technology choices, timeline and budget validated before a single line of code.

Week 1-2

Design & Prototyping

Wireframes of main screens, then high-fidelity mockups in Figma. Interactive prototyping to test user journeys before development. Design system to guarantee visual consistency across the entire application.

Week 2-4

Agile Development

2-week sprints with functional deliveries at each iteration. You test the features as you go. Front-end, back-end, API and integrations developed in parallel. Code reviews and automated tests at each commit.

Week 4-14

Production & Evolution

Final testing, performance optimization, deployment to production with CI/CD. Monitoring and alerts activated. Technical documentation and source code transfer. Maintenance plan and evolution to grow your platform over time.

Week 14+

Frequently Asked Questions

EVERYTHING ABOUT CUSTOM DEVELOPMENT

When should I opt for custom development? expand_more

Custom development is the right solution when classic CMS platforms (WordPress, Webflow, Shopify) are no longer sufficient to cover your needs. The most common signals: you need specific business features that no plugin covers, you need to connect multiple systems via API, you manage large data volumes, or you are building a SaaS product. Booking platforms, client portals, analytics dashboards, marketplaces, business applications — if your project does not fit within the constraints of a CMS, custom is the answer.

What technologies do you use? expand_more

We use a modern and proven technology stack. For the front-end: React and Next.js with TypeScript for fast, reactive and maintainable interfaces. For the back-end: Node.js (Express or NestJS) or Python (FastAPI, Django) depending on needs. For databases: PostgreSQL for relational data, MongoDB for unstructured data, Redis for caching. Deployment on Vercel, AWS or dedicated servers depending on performance and data sovereignty requirements. The technology choice is always justified by the concrete needs of your project.

How much does a custom development project cost? expand_more

Custom projects start at 8,000 euros for a simple web application (portal, dashboard). Medium-complexity platforms (basic SaaS, advanced client portal) range between 15,000 and 30,000 euros. Ambitious projects (marketplace, multi-tenant SaaS, complex business platform) range from 30,000 to 50,000 euros and above. Every project is unique and the budget depends on features, integrations and technical complexity. We provide a quote after a detailed brief and you receive transparent pricing with a precise timeline.

How long does custom development take? expand_more

A custom project generally takes between 8 and 16 weeks from specification to deployment. Simpler projects (client portal, dashboard) can be delivered in 6 to 8 weeks. Complex platforms (SaaS, marketplace) require 12 to 20 weeks. We work in agile 2-week sprints with incremental deliveries: you test the features as you go and can adjust priorities at each sprint.

Do I own the code? expand_more

Yes, 100% and without restriction. Upon project delivery, you receive the entirety of the source code hosted on your own Git repository (GitHub or GitLab). You also receive complete technical documentation, API documentation, and access to all services (hosting, database, monitoring). The code belongs to you fully. You can have it evolve with us, with an internal team or with another provider. No lock-in, no dependency.

Do you offer maintenance and project evolution? expand_more

Yes. We offer monthly maintenance and evolution plans adapted to every project. The maintenance plan includes bug fixes, dependency security updates, performance and availability monitoring, and backups. The evolution component includes a monthly volume of hours dedicated to developing new features. Your application grows with your business and adapts to your new needs. Plans start at 500 euros per month depending on project complexity.
