Service · SaaS Development

Build a SaaS product on foundations that scale.

We build multi-tenant platforms with the parts every SaaS needs — accounts, roles, billing, admin and analytics — so you can focus engineering effort on what makes your product different.

The problem

Every SaaS needs the same infrastructure before it can charge a customer: tenant isolation, authentication, permissions, subscription billing, an admin panel, usage tracking. Building these badly creates security and scaling problems that surface at the worst time.

  • Months spent rebuilding standard SaaS plumbing
  • Multi-tenancy and permissions done wrong are hard to fix later
  • Billing edge cases — proration, dunning, upgrades — eat time
  • No usage data to inform pricing or product decisions
Our approach

We build the platform layer properly once — tenant isolation, auth, role-based access, Stripe billing with the edge cases handled, an admin console and product analytics — then build your differentiated features on top. The architecture is designed for more tenants, more data and more team members from the start.

  • Secure multi-tenancy and role-based access
  • Subscription billing with proration, trials and dunning
  • Admin console for support and operations
  • Usage and product analytics built in
What's included

Inside every SaaS Development engagement

Auth & tenancy

SSO-ready authentication, organisations, invitations and strict tenant isolation.

Billing & plans

Stripe-backed subscriptions, usage-based pricing, upgrades and failed-payment recovery.

Admin & analytics

An internal console plus product analytics to see how accounts actually use the app.

Scalable architecture

Data model, background jobs and infrastructure designed to grow without a rewrite.

How it works

From first call to live in weeks, not quarters

Every phase has a defined output you can review before we move on.

  1. 01

    Product & scope

    We define the core value, the MVP feature set, and the pricing model the billing needs to support.

  2. 02

    Platform foundation

    We build tenancy, auth, roles, billing and the admin console first.

  3. 03

    Differentiated features

    We build the features that make your product worth paying for, in short cycles.

  4. 04

    Launch & operate

    We deploy, set up monitoring, and support the first customers and iterations.

Use cases

Where teams put this to work

New SaaS from scratch

Idea to launched, billable MVP with the infrastructure to grow into.

Internal tool to product

Turning a tool that works for you into a multi-tenant product other companies can buy.

Platform re-architecture

Rebuilding a product that's hit the ceiling of its original architecture.

Technology

Built on tools that hold up in production

We choose the stack for the job. Listing a tool here doesn't imply a partnership.

  • Next.js
  • TypeScript
  • PostgreSQL
  • Stripe
  • Auth providers
  • Vercel / cloud infra
Outcomes

What changes after launch

  • Standard SaaS infrastructure built right, once
  • Engineering time spent on your differentiator
  • Billing that handles the awkward cases
  • Data to guide pricing and roadmap
  • Architecture that scales with the business
