Stockwise: Order Management for WhatsApp Sellers

Selling on WhatsApp is easy. Keeping track of orders, inventory and customers in the middle of all those messages is much harder. Stockwise centralizes everything in under 30 seconds per order.

The problem

Stinova Bijoux managed its orders, customers and inventory in the middle of WhatsApp conversations.

What I built

Stockwise bridges the gap between informal selling on WhatsApp and structured business management. Sellers can create an order in under 30 seconds, track inventory in real time, generate a WhatsApp summary ready to copy and paste, and check their KPIs from a clear dashboard. The architecture follows DDD principles with 6 isolated modules: Auth, Users, Customers, Products, Orders and Dashboard, deployed on Render with 24/7 monitoring.

Key features

  • Google OAuth sign-in, no passwords
  • Multi-product order management with PENDING / DELIVERED / CANCELLED statuses
  • Automatic stock logic: reservation, release and deduction depending on order status
  • Automatic generation of a WhatsApp summary ready to copy and paste
  • Dashboard with real revenue, conversion rate, top products and critical stock alerts
  • PDF and Excel report exports, filterable by date, status and customer
  • 24/7 monitoring with Sentry, Winston and UptimeRobot

Result

Delivered in 3 weeks

An order is created in under 30 seconds, stock updates automatically, and the dashboard shows real revenue, conversion rate and critical stock alerts.
