SaaS Products

End-to-end SaaS development. We design, build, and ship subscription products — from blank canvas to paying customers.

What's included

  • Product discovery and roadmap
  • UX, UI, and design system
  • Authentication and authorisation
  • Billing and subscription management (Stripe, Paddle)
  • Multi-tenant architecture and data isolation
  • Admin tooling, observability, and analytics
  • Production deployment and ongoing support

Typical stack

  • TypeScript + Next.js or SvelteKit
  • Postgres (Supabase or Neon) for primary data
  • Stripe for billing
  • Resend or Postmark for transactional email
  • Vercel or Fly.io for hosting
  • Sentry + Plausible for observability

We use what we build.

Lumarix — our own ERP for accountants — is built on the same stack and approach we bring to client work.
