SaaS Development
Scalable Software as a Service platforms designed to handle complex business logic and grow with your user base.
Betty and Selim architect and build SaaS products from the ground up in Brussels: scalable architecture, clean dashboards, and reliable APIs that can support thousands of users without ever needing a rebuild. User accounts, role-based permissions, Stripe billing, and subscription tiers are configured from the start, so you can focus on your product instead of the technical plumbing. Your platform is also built to integrate with external apps, mobile clients, and partner systems from day one, with no workarounds or rearchitecting needed later.

SaaS development at Studio XL starts from €8,000. That starting price fits a focused first version (MVP) with the core functionality you need to reach your first users. The price grows with the number of modules and screens, the complexity of your business logic, and the integrations with other systems.
We define the scope together upfront, so you know exactly what the first version costs and what it contains. Because we design for scale from the start, growing from your first hundred users to your first thousands doesn't mean starting over.
What's Included
Built to Grow, No Rebuilding Needed
We design your platform to support hundreds, then thousands, of users from day one, so you never hit a wall and need to start over as you scale.
Subscriptions & Logins, Built In
User accounts, role-based permissions, Stripe billing, and subscription tiers, all configured from the start so you can focus on your product, not the plumbing.
A Dashboard Your Users Will Love
Clean, intuitive interfaces that make complex data easy to read, designed to feel professional, fast, and as polished as the products your users already trust.
Connects to Any Tool You Need
Your platform is built to integrate with external apps, mobile clients, and partner systems from day one. No workarounds or rearchitecting needed later.
Case Studies
Our Process
Discovery
You send us your project, and Selim gets on a call with you to talk through your business and what the site needs to do. If it's a good fit, we lock in a start date.
Strategy + Design Direction
Betty maps out the structure and strategy, based on a short questionnaire and what you told us on the call. Selim turns that into a visual direction for your brand.
Creation
[OUR FAVORITE PART]Once the direction is signed off, Selim builds it: a website, an app, or whatever the project calls for. You'll see progress along the way, not just a reveal at the end.
Delivery
Once everything is approved, we hand over your files and set you up to run the site yourself. Then it's live, and it's yours.
Frequently asked questions
How much does SaaS development cost? +
SaaS development at Studio XL starts from €8,000. That fits a focused first version (MVP) with the core functionality to reach your first users. The price grows with the number of modules and screens, the complexity of your business logic, and the integrations needed. We define the scope together upfront, so you know exactly what the first version costs.
What is an MVP and why start with one? +
An MVP is a focused first version of your product, limited to the core functionality your first users actually need. It gets you to market faster and lets real usage, rather than assumptions, decide what to build next. Because we design the architecture for scale from day one, extending the MVP doesn't mean rebuilding it.
Can you integrate subscriptions and online payments? +
Yes. Stripe billing, subscription tiers, user accounts, and role-based permissions are configured from the start. Your customers can subscribe, upgrade, and manage their plans without manual work on your side.
Will the platform scale as my user base grows? +
Yes, that's the core of how we build. We design the architecture to support hundreds, then thousands, of users from day one, so growth never forces a rebuild. APIs and integrations are part of the initial design too, so connecting mobile clients or partner systems later requires no rearchitecting.
