From product bet to running platform — multi-tenant SaaS development
UP2DATE builds multi-tenant SaaS platforms for EU and US companies — billing, analytics and cloud infrastructure engineered in from day one, so you launch on something that scales instead of a rebuild. A focused SaaS MVP typically ships in 10–14 weeks and runs €300–800 per month in cloud costs at early scale.

We help you define the solution, build it and support it after launch. For requirements and architecture, explore Product Discovery & Solution Blueprint or Business process automation. Together, we agree where to start and how to deliver.
Everything a production SaaS needs at launch
Multi-tenant architecture
Schema-per-tenant, row-level security or shared-schema — we choose the isolation model that fits your security requirements and operational cost, then build it so switching later does not require a rewrite.
Subscriptions & billing (Stripe)
Usage-based, seat-based or flat plans wired through Stripe Billing — trial flows, upgrade prompts, proration, failed-payment recovery and a self-serve customer portal all handled from the start.
Onboarding & admin tooling
Guided sign-up flows, workspace setup wizards and a robust internal admin panel so your team can manage accounts, debug issues and run customer success workflows without engineering involvement.
Usage analytics & metrics
Product instrumentation, funnel analysis and retention metrics wired into a dashboard your team can act on — not a data warehouse that requires a BI analyst to interpret.
Cloud infra & CI/CD
Infrastructure as code on Azure or AWS, preview environments per pull request, automated database migrations and zero-downtime deploy pipelines that ship with confidence from the very first sprint.
Security & data isolation
Tenant data isolation, RBAC, audit logs, secrets management and penetration-test-ready codebases — we treat security as an architecture concern, not an afterthought added before your first SOC 2 audit.
Proven SaaS stack — .NET, Next.js, Postgres, Stripe
We default to .NET on the backend for its mature ecosystem and long-term hiring depth, Next.js on the frontend for SEO and performance, PostgreSQL for relational data with row-level security, and Stripe for everything billing.
Every stack decision is justified against your scale targets, your team's future hiring market and the operational cost of running it in production — not against what is trending at the time of build.
Frequently asked questions
Can we start without technical specifications?
Yes. We start with your business objectives and existing systems. We define requirements and architecture with your team, then deliver in stages. If the scope is already clear, we can start directly with implementation.
Which multi-tenancy approach is right for my SaaS?
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.
How long until an MVP my first customers can use?
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.
How do you handle subscriptions and billing?
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.
What do running costs look like as we scale?
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.
Can you take over an existing SaaS codebase?
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.
