Project overview
A SaaS invoice management system that lets businesses handle all their invoices in one place. It serves business owners and their customers through separate, role-appropriate panels for administration, day-to-day management and payments.
The challenge
Businesses needed one place to create, manage and get paid for invoices, with clear separation between platform administration, business management and the customer's own view.
Our solution
We built the system with PHP, Laravel, Livewire and a SaaS architecture. A Super Admin panel handles users, subscriptions, inquiries and settings; an Admin panel manages categories, products, taxes, invoices and transactions; and a Customer panel lets users view and pay invoices, track transactions and manage their profile. It also supports custom invoice templates, currency management and company settings.
How we approached it
The three panels were modelled before any screen was drawn, because in a multi-tenant product the boundary between super-admin, business and customer is a security boundary rather than a navigation choice. We started with the data model — accounts, subscriptions, invoices, transactions and the relationships between them — then built the admin surfaces on top, and the customer-facing payment view last, once the invoice lifecycle it depends on was settled. Livewire kept the interactive pieces in the Laravel codebase rather than introducing a separate front-end application for what is largely form-driven work.
The results
Delivered a multi-tenant SaaS platform that lets businesses manage invoicing end to end and gives their customers a simple way to view and pay invoices online.
