Multi-tenant POS and inventory SaaS with Flutter vendor app

Web portals for platform, business and vendor admins pair with a Flutter vendor app for Android and iOS, where store staff run barcode checkout and live stock audits. Each retail tenant is strictly isolated, branch stock is kept in real-time ledgers, and the platform layer tracks subscriptions, tiers and MRR.

Designed and built by Nayesh Daggula as part of TechDino.
