Inventory & Warehouse Module

1. Module Overview

The Inventory & Warehouse Module gives you complete control over physical stock — from basic stock tracking to complex multi-zone warehouse logistics and distribution. It supports real-time balance tracking, bin-level slotting optimization, pick-path routing, automated replenishment rules, and advanced stock costing methods (FIFO, LIFO, Weighted Average, Standard Cost) with landed cost allocations.

Business Value:

Prevent Stockouts & Overstocking: Real-time multi-location stock visibility and automated reorder points (EOQ, safety stock).
Optimize Warehouse Space: Bin-specific slotting algorithms, put-away rules, and picking wave planning reduce foot travel and storage costs.
Precision Order Fulfillment: Multi-modal picking strategies (piece, case, batch, zone, or voice/RF) ensure shipping accuracy.
Accurate Stock Valuation: Double-entry inventory tracking dynamically updates asset values, including freight, duties, and landed cost allocations.
Traceability & Compliance: Strict serial number, batch/lot tracking, and shelf-life expiration date (SLED) controls support recall procedures.

Core Capabilities

Warehouse Management (WMS): Zone management, Slotting optimization, directed put-away, and pick path planning.
Stock Movement Audits: Complete transaction logs for stock adjustments, inter-location/inter-company transfers, and stock conversions.
Advanced Fulfillment: Wave planning, batch picking, cross-docking (bypassing storage for direct delivery), kitting, and custom packaging.
Multi-Client 3PL Support: Client-segregated inventories, service level agreement (SLA) monitors, and client-specific billing reports.

2. Key Concepts & Terminology

Term	Definition
Stock Balance	The current quantity of an item at a specific location, warehouse, or bin.
Stock Transfer	The movement of inventory between locations (warehouse-to-warehouse or bin-to-bin).
Stock Take	A physical inventory count compared against system records to identify and reconcile variances.
Stock Conversion	Transforming raw materials into finished components or bundling items into kits (Kitting/Assembly).
Stock Reservation	Earmarking specific stock quantities for confirmed sales orders, projects, or production tasks.
Slotting Optimization	The strategic placement of products within warehouse zones based on demand, velocity, and size.
Wave Planning	Grouping multiple customer orders into a single picking wave to optimize picking path efficiency.
Landed Cost	The total cost of an imported product including purchase price, freight, customs, duties, and transport.
Cross-Docking	Unloading incoming materials from a supplier and routing them directly to outgoing shipping docks.
FIFO / LIFO	Costing methods where oldest (FIFO) or newest (LIFO) inventory layers are cleared first.

4. Standard Business Workflows

Workflow 1: Inbound Receiving & Directed Put-Away

Supplier Delivery ──▶ Inbound DO ──▶ Quality Inspection ──▶ Slotting Rules Applied ──▶ Put-Away to Bin

Steps:

Supplier delivery arrives at the dock; staff verify items against the Inbound DO.
Items undergo quality checks (statistical sampling/damage review).
System applies slotting rules based on product weight and sales velocity.
Staff put away goods into the system-directed bin location (e.g., Aisle 2, Bin C-4) and scan the bin code.
Central inventory levels update immediately.

Workflow 2: Wave Planning & Optimized Picking

Release Orders ──▶ Wave Planning ──▶ Pick Path Optimization ──▶ Batch Picking ──▶ Pack & Ship

Steps:

A batch of customer sales orders is released for fulfillment.
Store manager opens Warehouse Management Applet to run a wave planning cycle, grouping orders.
System outputs optimized pick sheets sorting items by warehouse aisle sequences.
Pickers gather multiple orders simultaneously (batch picking) to minimize travel time.
Items are brought to sorting stations, verified, packed, and loaded for shipping.

Workflow 3: Cross-Docking Operations

Supplier Arrival ──▶ Dock Scheduling ──▶ Match Outbound SO ──▶ Staging ──▶ Outbound Dispatch

Steps:

Sourcing team arranges an inbound shipment for backordered customer items.
Upon dock arrival, system maps the inbound items to pending outbound Sales Orders.
Items bypass storage aisles and route directly to outbound staging zones.
Warehouse staff pack items directly into customer delivery vehicles.
System logs the receipt and shipping dispatch simultaneously.

Workflow 4: Cycle Counting & Balance Verification

Trigger Count Sheet ──▶ Physical Count ──▶ Variance Verification ──▶ Post Adjustment ──▶ Ledger Match

Steps:

Stock Take Applet triggers a cyclical count sheet for high-value A-class items.
Staff check bin locations, scan barcodes, and input physical counts.
System flags any variance exceptions between physical counts and system balances.
Supervisor investigates discrepancies and approves the variance.
Stock Adjustment is created and posted, adjusting the balance sheet inventory accounts.

5. Roles & Permissions

6. Prerequisites / Initial Setup

Before going live with the Inventory & Warehouse Module, ensure:

Core Module — Organisation profile, branch networks, and default warehouses exist
Chart of Accounts — Mapped accounts for inventory assets, cost of goods sold, and variance adjustments
Mapped warehouse layouts (aisle, shelf, and bin numbering scheme)
Mapped units of measure (UOM) conversion factors (e.g., Box of 12 to Pieces)
Mapped tax configuration codes matching import/landed cost rules
User profiles created for warehouse operators with mobile/RF scanner rights

Implementation Phasing

Phase 1: Warehouse Foundation: Establish location hierarchies (bins), design slotting/put-away rules, and map supplier catalogs.
Phase 2: Operational Workflows: Roll out inbound receiving, cycle counting matrices, picking paths, and POS/Sales reservation syncs.
Phase 3: Optimization & Costing: Setup landed cost allocations, blanket release workflows, safety stock algorithms, and 3PL multi-client configurations.

7. FAQs & Troubleshooting

Q: Stock Balance shows a negative quantity for an item. How is this possible? A: Negative stock occurs if the system allows transaction posting without checking physical stock availability. Check the Stock Report for the transaction history and run a corrective Stock Take or Stock Adjustment.

Q: A stock transfer was created but the destination hasn’t received the quantity yet. A: Inter-warehouse stock transfers require a two-step confirmation process. The originating site deducts stock (status: “In Transit”), and the receiving site must confirm physical receipt via the Stock Transfer Applet to close the ticket.

Q: How do we allocate landed costs (freight/duty) to inventory? A: Use the Landed Cost Allocation panel inside the Stock Balance Applet or Purchase GRN Applet. Select the inbound GRN shipment, enter the freight invoice amount, and choose to allocate cost by weight, value, or quantity across the line items.

Troubleshooting Common Issues

Pick Path Inefficiencies: Verify location master coordinates in the WMS. If aisle sequences are wrong, the pick sheet will direct pickers to double-back. Re-run slotting optimization to relocate fast-moving items.
Wave Planning Delays: Check queue bottlenecks. Ensure sufficient labor resources are assigned to the wave. If orders contain missing stock items, pause the wave and re-allocate stock via the Stock Reservation Applet.
Sync Integration Failures: If sales orders from E-Commerce fail to reserve inventory, verify API webhook connection statuses. Run the reconciliation reports in Stock Availability to highlight failed allocations.
