What we build in a SaaS platform

A SaaS product is more than its main feature. Around the core workflow it needs sign-up and onboarding, accounts and team members with roles, subscriptions and billing, an admin area for your own team, emails and notifications, and the security to keep each customer's data separate.

We scope which of these your first release needs, and build the rest in phases. Most SaaS MVPs launch with the core workflow, one or two roles, and simple billing, then add team features and reporting as customers ask for them.

Multi-tenant architecture and data security

In a SaaS product every customer's data lives in the same system, so separating it correctly is the most important technical decision. We typically use PostgreSQL with row-level security policies, so the database itself enforces which organisation can see which rows — not just the frontend code.

This is one reason we often build SaaS backends on Supabase, which runs on Postgres. Our Supabase vs Firebase comparison explains when each backend fits a SaaS product.

Tech stack for custom SaaS development

Our standard SaaS stack is Next.js and TypeScript for the web app and marketing site, PostgreSQL through Supabase for data, authentication, and storage, and a payment provider such as Stripe for subscriptions where it is available. When a SaaS product also needs a mobile companion app, we add React Native so the whole product shares one language.

Next.js matters for SaaS because your public pages need to rank on Google while your logged-in app stays fast. Our guide to Next.js vs React explains why we start new SaaS products on a framework.

SaaS development cost

A focused SaaS MVP — core workflow, accounts, and basic billing — usually falls in the standard or advanced MVP band, roughly $8k to $40k depending on roles, integrations, and reporting needs. Larger platforms are delivered in phases so you start earning before every feature exists.

FAQ

Can you add a SaaS product to our existing website?

Yes. We can build the SaaS app alongside your current site, or rebuild both on Next.js so the marketing pages and the product share one codebase and design system.

Do you build B2B SaaS with teams and roles?

Yes. Organisations, team invites, roles and permissions, and per-organisation data separation are standard parts of the B2B SaaS products we build.

Do you make us SOC 2 certified?

No. We can design security-conscious architecture that supports future compliance work. Formal audits are a separate program with specialized partners.

Web only or mobile too?

Either or both. Many SaaS products start on web and add React Native later; we plan APIs accordingly.
