Fashion Shop POS

Fashion Shop POS SaaS — Multi-tenant Retail Platform
Challenge

A growing fashion retail chain needed a unified Point-of-Sale (POS) system to manage inventory, sales, and online orders across multiple stores and wholesale operations. Existing solutions lacked seamless desktop-web synchronization, real-time data sharing between retailer and wholesaler workflows, and scalable multi-store support, causing inventory discrepancies and delayed reporting.

The business required a SaaS model to onboard new stores quickly, support both B2C and B2B scenarios, and provide intuitive interfaces for non-technical users. Key objectives included category/product management, automated invoicing, top-customer analytics, and secure payment processing.

Solution

We engineered a multi-tenant SaaS POS with ASP.NET Core APIs, Blazor Server/WebAssembly for a responsive web interface, and .NET MAUI desktop clients for store terminals. Tenant isolation used TenantId-based row-level security on a shared Azure SQL Database. Real-time sync across web, desktop, and mobile was achieved with SignalR.

Core Features
  • Tenant-specific product catalogs and category management
  • Invoice and purchase order automation with wholesaler-retailer toggles
  • Real-time inventory & sales sync via SignalR
  • Stripe payments with per-tenant credentials and webhook ledger sync
  • Interactive dashboards and analytics (Power BI Embedded)
