📦 Inventory Module

Purpose:

  • Tracks quantities, costs, and basic stock movements (e.g., purchases, sales, transfers).
  • Focuses on financial and inventory valuation (e.g., average cost, FIFO).

Key Features:

  1. Item Master Data
    • Manages item cards (SKUs, descriptions, costs, pricing).
  2. Basic Transactions
    • Records purchases, sales, and transfers without detailed location/bin tracking.
  3. Inventory Valuation
    • Calculates COGS (Cost of Goods Sold) and stock values.
  4. Stock Replenishment
    • Generates purchase orders based on reorder points.
  5. Simple Adjustments
    • Uses Item Journals to post inventory changes (e.g., losses, corrections).

When to Use:

  • Small businesses without complex warehousing needs.
  • Companies that only need to track “what” and “how much” (not “where”).

Example:

  • Posting a sales order reduces inventory quantity but doesn’t specify which bin the item came from.

🏗️ Warehouse Management Module

Purpose:

  • Manages physical storage, movement, and logistics within a warehouse.
  • Focuses on efficiency, space optimization, and labor tracking.

Key Features:

  1. Bin and Location Tracking
    • Tracks items by specific bins/zones (e.g., “Aisle 1, Bin 05”).
  2. Directed Put-Away & Pick
    • Automates storage/picking based on bin ranking, FIFO/FEFO, or zones.
  3. Advanced Documents
    • Uses Warehouse Receipts, Shipments, Pick Worksheets, and Put-Away Worksheets.
  4. Mobile Device Support
    • Enables barcode scanning and real-time updates for warehouse staff.
  5. Cross-Docking & Cycle Counting
    • Streamlines workflows for high-volume warehouses.

When to Use:

  • Medium/large warehouses with complex layouts or high SKU counts.
  • Businesses needing traceability (e.g., lot/bin tracking for compliance).

Example:

  • Receiving 100 laptops, assigning them to Bin A-01-01 (Rank 10), and picking them via FEFO rules.
