I have a fully-functional ERP written in core PHP with a MySQL backend. The next milestone is an Inventory Management module dedicated exclusively to stock tracking. No supplier or order features are needed at this stage. What I need built • Database changes to record products, stock movements (in, out, adjustments) and current on-hand quantities. • Clean, responsive PHP screens that blend with the existing UI for item setup, stock transactions and a real-time stock level dashboard. • Basic search, filter and export to CSV so staff can pull quick counts. • Low-stock thresholds with email alerts (SMTP already configured in the system). • Clear install/merge instructions and brief user documentation. Acceptance The module must install without breaking existing ERP functions, display accurate stock counts after sample transactions, and meet simple code-review standards (PSR-12, parameterised queries, no raw SQL injections). I will provide a code snapshot, database schema and access to a staging server. If this initial stock-tracking phase goes smoothly, we can discuss adding supplier or order processing down the line.
