Sales CRM

About the project

Sales CRM is an independent business system connecting customers, the catalogue, orders, inventory and analytics into one workflow. Managers can inspect customer records, sales history and order states, while status changes stay consistent with stock reservations.

The backend uses Go, chi and pgx; Vue and Pinia power the interface, and ECharts provides analytics. The project includes Ukrainian and English localisation, responsive screens and Playwright checks of key workflows.

The challenge

Keep sales and inventory aligned through stock reservations, history and price snapshots at order time.
