What We Build

Every Layer of a Production-Ready SaaS

From multi-tenant architecture to subscription billing and the user-facing product — we build the full SaaS stack so your team can focus on growth, not infrastructure.

Multi-Tenant Architecture

We design scalable multi-tenant systems — shared or siloed data models, tenant isolation, custom domains and white-labelling baked in from day one.

  • Tenant isolation & security
  • Custom domain support
  • White-label capability

Subscription Billing

Stripe or Paddle integration with plans, trials, seat-based pricing, usage metering, invoices, dunning and a customer billing portal — all wired to your feature gates.

  • Stripe / Paddle integration
  • Usage-based & seat pricing
  • Customer billing portal

Auth & User Management

SSO, social login, magic links, multi-factor authentication and a full team management system — invitations, roles, permissions and audit logs.

  • SSO & social login
  • Team & org management
  • Role-based permissions

Product Dashboard & UI

The core application UI your customers use every day — data tables, analytics, settings, notifications, onboarding flows and everything in between.

  • React / Next.js frontend
  • Onboarding flows
  • Admin & customer portals

APIs & Integrations

A public API for your customers, webhooks for events, Zapier or native integrations and an embeddable widget — so your SaaS fits into any workflow.

  • Public REST / GraphQL API
  • Webhooks & event system
  • Third-party integrations

Analytics & Monitoring

Product analytics to understand user behaviour, feature flags to control rollouts, error tracking and uptime monitoring — so you can iterate with confidence.

  • Product analytics setup
  • Feature flags
  • Error tracking & alerts
Why MetaLabs SaaS

Why Founders Choose Us to Build Their SaaS

Building a SaaS isn't just building a web app. It's multi-tenancy, billing, auth, onboarding and scalability — all working together from day one. We've built this stack before.

01

SaaS Architecture From Day One

We don't retrofit SaaS features onto a regular web app. Multi-tenancy, data isolation, plan enforcement and billing are foundational decisions made at the architecture stage — not added later.

02

Billing That Actually Works

Stripe integration with plan tiers, trial periods, seat-based pricing, usage metering, dunning flows and a customer portal — tested against real subscription scenarios, not just happy paths.

03

Built to Retain Customers

Onboarding flows, activation tracking, empty states and in-app guidance aren't nice-to-haves — they're the difference between users who stick and users who churn. We design them in.

04

Scalable Infrastructure

Connection pooling, caching, background jobs and horizontal scaling architecture built in from the start — so your SaaS doesn't need a rewrite when you hit 10,000 customers.

Our Process

From Idea to Paying Customers

A structured process for building SaaS products — from validating architecture decisions early to shipping the features that drive activation and retention.

01
Step 01

Discovery & Architecture

We define your tenant model, billing structure, feature set and integrations — producing an architecture document before writing code.

Auth, Billing & Tenancy

The SaaS foundation — multi-tenant database, auth system, Stripe subscription integration and plan enforcement gates — built and tested before the product UI.

FAQ

SaaS Development Questions

Common questions about building SaaS products with MetaLabs Tech — from architecture decisions to billing and scaling.

Yes — we work with founders from idea to launch. We start with a product discovery workshop to define features, user flows and the MVP scope, then design and build iteratively so you can get in front of early customers as quickly as possible rather than waiting for a perfect v1.

A SaaS product is built for multiple customers (tenants) from the start — with subscription billing, tenant isolation, plan-based feature gating, team management and onboarding flows. A regular web app typically serves a single organisation. Building a SaaS requires specific architectural decisions that are expensive to retrofit later.

We integrate Stripe or Paddle with your chosen pricing model — flat rate, per-seat, usage-based or hybrid. We build the plan enforcement logic into your application, set up trial periods, dunning emails for failed payments, and a customer billing portal for self-service upgrades, downgrades and cancellations.

We implement row-level security (RLS) in PostgreSQL or a separate schema/database-per-tenant model depending on your compliance and scale requirements. Every API route and query is tenant-scoped and access-controlled so one customer can never access another's data, even if an auth token is compromised.

If your product requires it, yes. We build public REST or GraphQL APIs with API key management, rate limiting and full OpenAPI documentation — so your customers can integrate your product into their own workflows and tools.

A focused MVP with auth, billing, core product features and onboarding typically takes 10–16 weeks. Larger products with complex data models, many integrations or custom analytics take longer. We agree the scope and timeline after discovery — and prioritise ruthlessly to get you to market fast.

Yes. We offer ongoing product development retainers — adding features, improving performance, handling infrastructure scaling and iterating based on user feedback and analytics — so you can keep shipping without needing to hire and manage an in-house team from day one.
