Building a Multi-Tenant SaaS Application with Laravel

Building a multi-tenant SaaS application requires careful architecture decisions. In this guide, we'll walk through the key considerations and implementation strategies. ## What is Multi-Tenancy? Multi-tenancy allows a single instance of your application to serve multiple customers (tenants) while keeping their data isolated. ## Architecture Approaches ### 1. Database-per-Tenant Each tenant gets their own database. This provides maximum isolation but increases complexity. ### 2. Shared Database, Tenant Column All tenants share the same database, with a tenant_id column on each table. Simpler but requires careful scoping. ### 3. Schema Isolation Each tenant gets their own schema within a shared database (PostgreSQL only). ## Implementation with Laravel Using Laravel's service container, middleware, and global scopes, we can implement any of these approaches cleanly. ## Subscription Billing Integrating Stripe or Razorpay for subscription management is straightforward with Laravel Cashier. ## Conclusion Multi-tenant SaaS is a proven business model, and Laravel provides all the tools needed to build one effectively.
