Overview

White-label SaaS Platform is a multi-tenant application designed to be rebranded and resold. Each tenant (an agency's client) gets their own custom domain, branding, plan, and isolated data, while the platform owner manages tenants, plans, and billing centrally.

It is built for agencies and founders who want to sell a SaaS under their own or their clients' brands — one codebase serving many isolated, individually branded customers with subscription billing.

The problem

Serving many clients from one SaaS means solving multi-tenancy, per-tenant branding and domains, plan management, and billing — the hardest parts of a B2B platform. This delivers that foundation so an agency can rebrand and resell without rebuilding it.

Who it's for

  • Agencies wanting to resell a SaaS under client brands.
  • Founders building a B2B platform for many organisations.
  • Businesses needing isolated, branded tenants with central control.

Features

Custom domain per tenant

Each tenant runs on its own domain with its own branding, so the product looks like theirs.

Tenant isolation

Every tenant's data is isolated, so customers never see each other's information.

Plan management

Define plans and assign them per tenant, controlling features and limits centrally.

Subscription billing

Tenants are billed on subscription plans through Stripe, with the platform managing revenue.

Central admin

The platform owner manages all tenants, plans, and billing from one control panel.

User stories

  • As an agency, I want to rebrand the platform per client so that it looks like their own product.
  • As a tenant, I want my data isolated so that it stays private.
  • As the owner, I want central plan and billing control so that I manage the business in one place.
  • As a tenant admin, I want my own domain so that my users trust the product.

User flow

  1. 1

    Create tenant

    The owner provisions a tenant with branding, a domain, and a plan.

  2. 2

    Tenant uses platform

    The tenant's users access the branded app on their own domain.

  3. 3

    Manage plans

    The owner adjusts plans and limits per tenant centrally.

  4. 4

    Bill subscriptions

    Tenants are billed on their subscription plan.

Architecture

A Next.js application with Supabase and Stripe, designed multi-tenant from the ground up. Tenant resolution maps each custom domain to the right tenant, and data is isolated per tenant with strict access rules.

Plans and feature limits are managed centrally and enforced per tenant, and subscription billing runs through Stripe for each tenant.

The architecture is built to scale to many tenants from one codebase, which is what makes reselling viable.
