Multi-Tenant SaaS ERP System

A modern multi-tenant SaaS ERP platform designed to help organizations manage their core business operations from a single centralized system.

The platform covers sales, purchasing, inventory, CRM, accounting, team management, and workforce operations, with each organization operating inside its own secure tenant workspace. A separate administration panel allows the SaaS operator to manage organizations, subscription plans, and platform-wide settings.

The system was built using a modular monolith architecture, allowing each business domain to remain isolated, maintainable, and easy to extend as the platform grows.

Key capabilities include:

• Sales invoices, quotations, payments, and sales returns

• Purchase orders, purchase invoices, receipts, and supplier payments

• Warehouse, stock, and inventory movement management

• Customer and supplier management

• VAT and financial reporting

• End-of-day business reports

• Product and unit management

• Role-based access control and permissions

• Organization-level data isolation

• Subscription and plan management

• Audit logs and activity tracking

• Document attachments and PDF generation

• Human-readable sequential references for invoices and business documents

• Real-time dashboards and operational insights

The platform includes two dedicated interfaces: an Admin Panel for managing the SaaS platform and an Organization Panel for employees to manage daily business operations.

Built with Laravel 13, PHP 8.4, Filament 5, Livewire 4, Tailwind CSS 4, and a modular architecture powered by nwidart/laravel-modules. The system was designed with scalability, maintainability, security, and future business expansion in mind.
