Some business needs cannot be met by off-the-shelf solutions. MRTN Studio builds custom SaaS applications and internal tools for companies with specific processes to automate, data to centralise or teams that need efficient business interfaces. Our approach combines technical rigour, thoughtful user experience and scalable architecture to create tools that integrate naturally into your day-to-day operations.
Developing a SaaS product or business tool is a long-term investment. It must be built on a solid technical foundation, a clear architecture and decisions that anticipate growth. We work from functional scoping through to deployment, covering interface design and back-end development, to deliver a complete, documented and evolvable tool.
ImmoClass is software we designed, built and run ourselves. It receives an estate agency's paperwork (insurance certificates, property tax notices, leases, diagnostic reports), recognises each document type, extracts the useful information and files it in the right folder.
Its first user is a family-run lettings agency in the Alpes-Maritimes, managed by the father of MRTN Studio's founder. We say so because it is the truth, and because it is what made the product demanding: it was built alongside a team that uses it every day.

Turning an idea or an existing process into a SaaS application requires rigorous scoping. We begin by understanding your workflows, technical constraints and the user profiles who will interact with the tool every day. This analysis lets us define a realistic functional scope, prioritise which features to build first and design an architecture that can evolve without being rebuilt.
Interface design is central to this phase. A business tool must be understood immediately by its users, even without training. We design clear, efficient interfaces that reduce friction and accelerate internal adoption. Our web design in Nice expertise applies fully to SaaS interfaces, with particular attention to dashboard readability and complex form design.
We build SaaS applications with modern, proven technologies: Next.js for the front-end, REST or GraphQL APIs for data exchange, relational or document databases according to project needs, and serverless architectures for scalability. Every technical choice is documented and justified based on your cost, performance and long-term maintainability constraints.
Integration with existing systems is often part of the project: connecting to a CRM, ERP, billing tools or third-party APIs. We manage these integrations with care to ensure reliable data exchange. For projects that also require a public-facing website, our web development in Nice service can complement your business tool.
The goal of a custom business tool is to eliminate repetitive tasks, centralise information and give your teams more time for high-value activities. We identify automatable processes together: document generation, notification sending, data synchronisation, complex calculations or approval workflows. Each automation is designed to be reliable, traceable and easy to evolve.
A well-designed SaaS product quickly becomes a competitive advantage. If your project also involves a digital growth strategy, our digital strategy in Nice page explains how we approach the marketing and SEO dimension. For a comprehensive partnership, our web agency in Nice can manage the entire project.
A business tool is not priced as a flat package: everything depends on scope. Here is how we frame the budget, the schedule and what belongs to you at the end.
Every business tool is unique: the quote is prepared after a free scoping session that defines the functional scope, line by line. As a reference point, a website with a content management back office sits between €3,000 and €3,500.
We prioritise the features that deliver the most value so you get a working first version quickly. The precise schedule is set during scoping, with sign-off milestones at every stage.
The source code is delivered in your name and your data remains exportable at any time. No lock-in: the hosting and maintenance subscription has no minimum commitment, you cancel whenever you decide.
The price depends entirely on the functional scope: number of screens, business logic, integrations with your existing tools. That is why we start with a free scoping session that leads to a detailed, line-by-line quote. As a reference point, a website with a content management back office sits between €3,000 and €3,500.
It depends on the scope. Our approach is to deliver a usable first version focused on the highest-value features, then iterate. The precise schedule, with its sign-off milestones, is handed to you at the end of the scoping phase.
No. If you have one it is a good starting point, but it is not a prerequisite: the scoping phase exists precisely to formalise your workflows, constraints and priorities together. You arrive with a need, you leave with a scoped and priced project.
Yes. Integration with a CRM, an ERP, billing software or a third-party API is often part of the project. These connections are scoped from the start to guarantee reliable data exchange.
You do. The source code is delivered in your name and your data remains exportable at any time. Hosting and maintenance are options with no minimum commitment: you can bring the tool in-house or switch providers whenever you wish.
