The problem

The client, a footwear manufacturer, ran orders, production, stock and payments across spreadsheets and paper, with no single view of costs or what was stuck where.

What I built

Orders, bills of materials with permanent product codes, and production runs tracked stage by stage
Split orders into batches that flow independently through production, warehouse and invoicing
Warehouse stock (good and defective), material shortages that block production, automatic stock restoration
Procurement: purchase orders, goods received, purchase invoices and vendor payments
Sales invoices, receivables and payables, client / vendor / employee statements
HR: employees, attendance and payroll; asset tracking
12 Excel reports
Role-based access: admins choose exactly which of 21 pages each manager can see
Automatic backups with restore
AI assistant: chat about the business, a daily executive briefing, 10 automatic anomaly alerts (stuck batches, overdue invoices, stock problems), a production planner, and an "autopilot" that can approve or hold orders while the owner is away — every AI decision is logged and reversible with one click

How it's built

React front end with server functions, PostgreSQL with database-level rules and triggers for stock and costs, and the AI assistant reading live business data.
