What you get

End-to-end SaaS

Auth, subscriptions, billing, dashboards, admin and integrations — the full platform, not just a front end.

Multi-tenant architecture

Built to serve many customers securely from day one, so growth doesn't force a rebuild.

Subscription billing

Stripe or Paddle billing, plans and usage limits wired in and working, not left as a to-do.

Dashboards & analytics

Clear product analytics and admin tooling so you understand and act on how customers use your app.

AI features

Add AI-powered features — assistants, generation, search — where they create real value.

Secure & compliant

Sensible security defaults and EU-friendly data practices from an Estonian company.

Why founders choose us

  • One senior team for design, frontend, backend and infra
  • Modern, maintainable stack you can hire for
  • Fixed scope and transparent pricing up front
  • Billing and subscriptions that actually work at launch
  • Estonian software company (160418 OÜ) with EU compliance
  • A platform you fully own

What SaaS development includes beyond the app itself

A SaaS product is a business system, not just a UI. Alongside the core feature set you need multi-tenant data isolation, authentication and roles, subscription billing with trials and proration, an admin back office, usage analytics, transactional email and a support path. Skipping these is how a promising v1 stalls after the first ten customers.

We build all of that as part of the platform, on architecture that keeps your per-customer cost flat as you grow.

  • Multi-tenancy and row-level security so one customer can never see another's data.
  • Stripe or Paddle billing: plans, trials, upgrades, dunning, invoices and EU VAT handling.
  • Roles, teams and invitations — the feature every B2B buyer asks about in the demo.
  • Product analytics and event tracking so you can see activation and churn, not guess at them.

How long a SaaS platform takes to build

A focused SaaS MVP with auth, billing and one strong core workflow is a matter of weeks. A full platform with integrations, an admin suite and enterprise requirements takes longer — and should, because rebuilding a rushed data model later costs far more than designing it once.

We sequence releases so you have something sellable early: launch the paid core first, then expand along the roadmap your customers actually pull you toward.

Choosing a SaaS development company

Ask any prospective partner three things: what happens to the code and infrastructure if we stop working together, how do you handle billing edge cases, and can we see a product you built that is still live and paying. You own everything we build — repository, cloud accounts, domains — from day one.

Who this is for

  • Founders with a defined problem and users to talk to, who need a senior team to design and build the product.
  • Companies that need an external product team to own delivery end to end, not staff augmentation.
  • Teams replacing a prototype or no-code build that has hit its ceiling.

Who this is not for

  • Projects looking for the cheapest possible hourly rate — we work in scoped phases with senior people.
  • Briefs with no decision maker available during delivery; we need weekly decisions to move fast.
  • Requests to "just add developers" to an existing team without a clear product scope.

What drives the cost

We quote per phase after a scoping call. These factors move the number up or down.

  • Scope depth — how many user roles, flows and states the first release really needs.
  • Integrations — payments, auth providers, third-party APIs and anything with certification steps.
  • Platforms — web only, or web plus iOS and Android with store review cycles.
  • Data and AI — model usage, evaluation work and the infrastructure around it.
  • Compliance and legal constraints in your market, which change design and delivery time.

Risks, and how we handle them

Scope grows during delivery

We fix the phase scope in writing, keep a visible backlog, and take new ideas into the next phase instead of stretching the current one.

The first release misses what users need

We define what success means before the build, ship in weekly increments and adjust from real usage rather than assumptions.

Handover leaves you dependent on us

Your company owns the repositories, infrastructure and accounts. We document the architecture and can hand the codebase to your own team at any phase boundary.

Timeline slips on external factors

Store reviews, third-party approvals and content dependencies are tracked as explicit dates in the plan, not assumed away.

Frequently asked questions

What does a SaaS development company do?

A SaaS development company designs, builds and launches software-as-a-service products — cloud web applications that customers pay for by subscription. That includes accounts and auth, billing, dashboards, integrations and the infrastructure to run it reliably.

Can you build a SaaS MVP first?

Yes. We usually start with a focused SaaS MVP so you can get real paying customers quickly, then expand it into the full platform on the same scalable codebase.

Do you handle subscriptions and billing?

Yes. We integrate subscription billing (Stripe or Paddle), plans, trials and usage limits so revenue works from day one.

What tech stack do you use?

A modern, widely-supported stack for web, backend and data, chosen so your product is fast, scalable and easy to hire for later.

How much does SaaS development cost?

It depends on scope. We define a clear, fixed scope and price before starting, and can phase the build to match your budget and funding.
