# Inventory  Module for Concord CRM

## 🏗️ Stock Structure

#### 📝 Basic Information

* **Product**: Pulled from the product catalog
* **Warehouse**: Storage location (optional on creation)
* **Bin**: Sub-location within a warehouse (optional)
* **Quantity**: Total units of the product in stock
* **On Hold**: Units reserved for pending shipments
* **Available**: Actual available quantity (Quantity - On Hold)
* **Created By**: User who initiated the stock creation
* **Cost Price**: Purchase cost per unit from supplier
* **Selling Price**: Calculated selling price including tax

*🗒️ Note: Warehouse and Bin fields can be empty if stock is not yet assigned to a specific location.*

## ⚙️ How Stocks Work

#### 1️⃣ Stock Creation

Stocks are automatically created **after receipt items are confirmed**.

* Each receipt item becomes a stock record
* Stock entry includes:
  * Product information
  * Quantity received
  * Cost and selling prices
  * Created By user
  * Optional Warehouse and Bin if known at time of creation
* Stock records are linked back to the originating receipt
* Available quantity equals total quantity initially

#### 2️⃣ Stock Holding System

When shipments are created:

* System validates stock availability
* Required quantities are placed "on hold" using FIFO method
* On-hold stock cannot be used for other shipments
* Available quantity is reduced by on-hold amount
* Stock is released when shipment is processed or cancelled

## 🔧 Stock Actions

#### 🔄 Put Away

Used to assign or transfer stock to a specific warehouse and bin.

**👇 Action Interface:**

* **Source (optional)**: From existing warehouse and bin (if assigned)
* **Destination**:
  * Warehouse (selectable)
  * Bin (selectable based on warehouse)

**🔁 Logic:**

* If the stock is **unassigned**, it's placed into the selected warehouse/bin
* If already assigned, stock is **transferred** to the new warehouse/bin
* Stock quantity remains the same
* Creates stock ledger entries for audit trail

#### 📉 Stock Adjustment

Used to **increase or decrease** existing stock quantity for various operational reasons.

**👇 Action Interface:**

* **Action Type**: Increase / Decrease
* **Quantity**: Number of units to add or subtract
* **Reason**: Mandatory text input explaining the adjustment

**🧠 Logic:**

* Quantity is adjusted as per user input
* Reason is stored in audit for traceability
* Used for correcting errors, handling losses, or manual adjustments
* Creates appropriate stock ledger entries
