Webdesign
Company websites, landing pages, and web platforms: design, SEO structure, GDPR-ready cookies and privacy, and hosting. Same team, same stack as the rest of your software.
Custom Software
Software development agency in Luxembourg
Not another off-the-shelf tool
Generic software makes you adapt. Custom software adapts to you.
Most “business software” forces your team into someone else's workflow, padded with features you'll never use and licence costs that scale against you. Custom software is different: it is built around your process, your data, and your growth.
- Built for your workflow
- No bending your process to fit a template. We design screens, data, and logic around how your team actually works.
- You own it
- No per-seat licence creeping upward as you grow. The code, the data, and the roadmap belong to you.
- Designed in Luxembourg
- Architecture, data handling, and support from a team that understands GDPR and how SMEs here actually work.
Deploy faster
A better workflow
We create modern software solutions tailored to your business, from web apps and platforms to automation systems and integrations. As a full-stack development partner, we simplify the complex and help you scale efficiently.
- Custom software, no bloat.
- Whether you're automating internal workflows or launching a new product, we build exactly what you need, and nothing you don't.
- Websites, web apps & cloud ready.
- From a fast, SEO-ready company website to customer portals and web apps. Everything runs where your users are: in the browser or in the cloud.
- Built for maintainability.
- We follow clean architecture principles, write clear documentation, and support your stack with maintainable, well-tested code.
What we build
Software for the systems your business runs on
We start from one real gap: a process still running on spreadsheets, a customer flow with no self-service, or data locked in two systems that don't talk. Typical projects for Luxembourg SMEs:
Internal tools & back office
Replace spreadsheets and manual hand-offs with a system that matches how your team actually works.
Customer & booking platforms
Portals, booking flows, and self-service tools your customers can use without calling you.
ERP & business systems
A lean ERP built around your processes: orders, stock, projects, and invoicing in one system, without the modules you will never use.
Integrations & automation
Connect your ERP, CRM, and finance tools so data moves once, correctly, without manual re-entry.
Web apps
Customer-facing or internal web applications, built on one shared backend your team can actually own.
Stack
The technologies we actually use
We choose the stack for the job, not a one-size-fits-all template. Code you can read, extend, and hand off.
How we deliver
From discovery call to software in production
A short, honest path. If custom software is not the right investment, we will say so on the first call.
Week 0
Discovery & planning
15 minutes to start. We dig into your goals, current infrastructure, and requirements to scope a solution for cloud, on-premise, or hybrid.
Weeks 1–2
Prototyping & design
Wireframes, mockups, and UX flows validate the direction early, so feedback happens before we write production code.
Weeks 2–8
Development & testing
Automated CI/CD, code review, and full test coverage, built in short cycles so you see real progress every week.
Ongoing
Deployment & maintenance
A smooth launch to cloud infrastructure, your own servers, or a hybrid setup, plus monitoring and a Luxembourg contact for what comes next.
Start with a discovery call
No deck. We look at the process you want to fix and tell you honestly whether custom software is the right investment, or whether an off-the-shelf tool will do.
Book a discovery call
Pick a time that works for you. We'll talk through your project and see how NexClass can help.
FAQ
Questions we hear before the first project
How much does custom software cost?
It depends on scope: a focused internal tool and a customer-facing platform are different projects. After the discovery call we give you a clear estimate before any development starts, not an open-ended hourly quote.
How long does a project take?
A first working version is typically weeks, not months. We build in short cycles so you see real progress early rather than waiting for one big launch.
Do you also build websites?
Yes. Web design is part of our software work: company websites, landing pages, and web platforms, including responsive design, SEO structure, GDPR-ready cookie and privacy setup, and hosting. Same team, same stack, one contact in Luxembourg.
Do we get a say in the technology?
Yes. We recommend a stack based on your team, your existing systems, and long-term maintainability, and explain the trade-offs. The decision stays with you.
Do you build ERP systems?
Yes. ERP is part of our custom software work. We either build a lean ERP around the way you already work, or extend and connect the system you run today, instead of pushing your business into a standard product.
Can you work with our existing systems?
Usually yes. Most projects connect to an existing ERP, CRM, or database rather than starting from a blank slate. We scope integrations during discovery.
Who owns the code once it's built?
You do. There is no licence lock-in: the source code, the data, and the infrastructure are yours.
What happens after launch?
We stay on as your Luxembourg contact for monitoring, fixes, and new features, on a support arrangement that fits your budget, not a mandatory long-term contract.
