The Challenge
Centralize commercial management for businesses with multiple stores. Each client needed to manage inventory, sales, customers, and billing without mixing data with other tenants, and to rely on up-to-date financial reports for decision-making.
The Solution
I implemented a multi-tenant SaaS architecture with per-client data isolation and secure authentication. I built the inventory, sales, billing, and real-time financial reporting modules, along with an interface to manage multiple stores.
