SaaS platform development, from architecture to production
Subscriptions, multi-tenancy, roles and billing are where SaaS projects stall. We have shipped all of it — and we build it into the architecture in the first sprint, not after launch.
- 8-14 weeks
- Fixed-price sprints
- Multi-tenant from day one
What we build
Multi-tenant architecture
Isolated data per tenant on shared infrastructure — the model that lets one deployment serve salons, auto shops and clinics at the same time.
Subscriptions & billing
Stripe with EU VAT handling, plan upgrades, trials, invoices and failed-payment recovery.
Roles & permissions
Owners, staff and admins, with access enforced on the API — not just hidden in the interface.
Admin & analytics panels
The internal tooling your team actually runs the business on: usage, revenue and support.
Integrations & automation
Webhooks, document generation, automated notifications and third-party APIs.
Scale & reliability
PostgreSQL, Redis, CI/CD, monitoring and error tracking wired in from the first deploy.
What you get

- Your repository, full code access throughout
- CI/CD, monitoring and error tracking
- Post-launch support and iterations
Stack we use
- NestJS
- Next.js
- PostgreSQL
- Redis

Proof of work
Zapys24 — CRM and Online Booking for Service Businesses
A multi-tenant platform where a booking reserves a set of resources, not just a person. Double bookings are rejected at the database level, clients get reminders, and the business runs everything from the web or the app.

How long does it take to build a SaaS platform?
A focused MVP takes 6-8 weeks. A full multi-tenant platform with billing, roles and admin panels typically runs 10-14 weeks. Zapys24, a multi-tenant booking SaaS, took 14 weeks from spec to production.
How much does SaaS development cost?
We work in fixed-price sprints, so the cost of each stage is agreed before it starts. The total depends on scope — a discovery call and technical spec give you an exact estimate, free and with no commitment.
Do you build multi-tenant architecture?
Yes, and we recommend deciding it up front. Retrofitting tenant isolation into a single-tenant codebase is one of the most expensive rewrites in SaaS, so we design that boundary in the first sprint.
Which tech stack do you use for SaaS?
NestJS and PostgreSQL on the backend, Next.js on the frontend, Redis for caching and queues, Stripe for billing. Proven tools chosen so you can hire for them later.
Do we own the code?
Yes. Work happens in your repository from day one and you have full access throughout. No vendor lock-in, no handover fee.
