SaaS platform development, from idea to launch
We build SaaS platforms from scratch: multi-tenant architecture, subscriptions with recurring payments, self-service onboarding and RO-compliant invoicing. A SaaS MVP typically takes 2–4 months and costs 8,000–25,000 EUR, with the full source code handed over. We work in Next.js and PostgreSQL, with European hosting.
What a properly built SaaS platform includes
A SaaS is not just a web app with a login. The difference is made by the components your customers don't see but do feel: data isolation, payments that run on their own, accounts that manage themselves.
Multi-tenant architecture
Proper data isolation between customers, decided from the start — not improvised when the second customer shows up.
Subscriptions and recurring payments
Stripe for payments, plans and trials, plus RO-compliant invoicing (SmartBill/Oblio, e-Factura).
Self-service onboarding
Sign-up, account setup and first steps without your team's intervention — essential for scaling.
Roles, organizations, audit
Role-based permissions, organization accounts and an audit log for business customers.
GDPR and data in the EU
European hosting, data minimization, export and deletion on request — designed in, not bolted on later.
Code fully handed over
Repository, documentation, CI/CD — the code is yours, no vendor lock-in.
How much SaaS platform development costs
We publish real ranges, not “from 99 EUR”. The final quote comes after a Discovery session in which we define the critical flows together. More details in our guide to SaaS platforms and in the MVP cost guide.
SaaS MVP
8,000–25,000 EUR
Validating the idea: basic multi-tenancy, authentication and organizations, recurring payments, one complete core flow, admin panel
Mature platform
30,000+ EUR
Advanced roles and permissions, public API, multiple integrations, reports, SLA and scaling
Monthly operation
100–500 EUR/month
European hosting, monitoring, backups, security updates — at the start; grows with volume

Frequently asked questions
How long does it take to develop a SaaS MVP?
Usually 2–4 months to the first launchable version. The exact duration depends on the number of critical flows and the integrations required — we set it together in the Discovery session.
How much does a SaaS platform cost?
A SaaS MVP typically costs 8,000–25,000 EUR, while a mature platform exceeds 30,000 EUR. We publish real ranges so you can budget correctly; the final quote comes after Discovery.
Who owns the source code?
You do, 100%. On handover you get full access to the repository, documentation and the CI/CD pipeline — with no dependence on us.
What technologies do you build on?
Our typical stack: Next.js and React for the application, PostgreSQL for data, European hosting (relevant for GDPR). We choose pragmatically, not by fashion.
Does recurring billing work with Romanian legislation?
Yes — we integrate Stripe or another processor for subscriptions and connect RO-compliant invoicing (SmartBill/Oblio, e-Factura) as part of the project, not as an afterthought.
