🧠 What Is the Inventory Management Module in ERP?

It’s the core ERP module that tracks, controls, and optimizes your stock — from raw material to finished goods — across warehouses, batches, and time.

It manages:

  • Stock levels
  • Item movement
  • Locations (racks, bins, floors)
  • Batch/lot tracking
  • Valuation methods
  • Reorder alerts
  • Expiry and QC checks

📈 Everything is updated in real time — with zero manual effort.


⚙️ How the Inventory Module Works – Step-by-Step

1️⃣ Stock Enters the System
Through GRNs, production, returns, or transfers.

2️⃣ Stock Moves Internally
Between warehouses, bins, production lines, and delivery zones.

3️⃣ Stock Goes Out
Via sales, production usage, scrap, or adjustments.

4️⃣ ERP Updates Live Stock
Shows free/reserved/incoming stock, batches, expiry, QC status.

5️⃣ ERP Triggers Smart Alerts
Auto-purchase suggestions, low stock warnings, expiry notifications.
