SaaS development from idea to first hundred customers

It depends on your compliance requirements and the size differential between tenants. Schema-per-tenant gives the strongest isolation and easiest per-tenant restores but carries higher operational overhead as you grow past a few hundred tenants. Row-level security on a shared schema scales further with less overhead but demands rigorous policy auditing. We walk through this trade-off in discovery and recommend based on your specific regulatory exposure and growth projections.

A focused SaaS MVP — core feature set, auth, multi-tenancy skeleton, Stripe billing and a basic admin panel — typically takes 10–14 weeks with our team. We use weekly demos from sprint one so you can redirect scope based on early user feedback rather than waiting for a big reveal. AI-assisted code generation on boilerplate and test scaffolding shaves another 2–3 weeks off that baseline.

We integrate Stripe Billing with your plan structure — whether that's flat monthly, per-seat or usage-metered. This includes trial periods with automatic conversion, upgrade and downgrade flows with correct proration, Stripe webhook handling for payment events, a customer self-serve portal for card management, and retry logic for failed payments with dunning emails. Billing is always a first-class feature in our SaaS builds, not bolted on late.

For a typical early-stage SaaS serving a few hundred active tenants, monthly cloud costs on Azure or AWS run €300–800 depending on compute and storage profile. We size infrastructure conservatively at launch and include auto-scaling policies so costs track actual usage rather than over-provisioned capacity. We also provide a cost model with estimates at 1k, 10k and 100k tenants so you can forecast before you are in that situation.

Yes — we do this regularly. The first step is a two-week audit covering architecture, test coverage, security posture and technical debt density, delivered as a written report with a prioritised remediation roadmap. From there we either staff into your existing team or take full ownership of the codebase depending on your preference. We will tell you honestly if the codebase warrants a partial or full rewrite rather than continued patching.
