Stock Multiplier for WooCommerce solves a critical inventory challenge: selling products in packs while accurately tracking individual units. Whether you sell 6-packs of beverages, bundles of 3 items, wholesale cases, or fabric by the meter – this plugin automatically calculates the correct inventory reduction and tracks every single stock movement with a complete audit trail.

The Problem: You sell a 12-pack of soda, but WooCommerce only reduces your inventory by 1. You need to manually track that you actually sold 12 individual cans.

The Solution: Set a stock multiplier of 12. When someone orders 1 pack, your inventory automatically reduces by 12 units. Plus, you get a complete history of every change – who made it, when, and which order caused it.

Perfect for online stores selling bundles, packs, wholesale quantities, bulk products, or any multi-unit items where accurate inventory tracking is essential for business operations.

Key Features

Stock Multiplier System:
* Custom Multipliers for Any Product – Set different multipliers for simple products and each product variation independently
* Automatic Calculation – Stock automatically reduces by (quantity ordered × multiplier) – no manual math needed
* Smart Inheritance – Variations without a multiplier automatically use the parent product’s setting
* Works for All Product Types – Simple products, variable products, and every variation individually

Complete Inventory History & Audit Trail:
* Track Every Stock Change – Automatic logging of all inventory movements (orders, manual updates, refunds, etc.)
* Detailed Audit Information – See date/time, before/after quantities, who made changes, and which order caused it
* Dedicated History Tab – View last 100 stock movements directly in the product edit page
* Order Linking – Click any order number to view the full order details
* Notes System – Add context and notes to manual stock adjustments

User Experience:
* Zero Configuration – Works immediately after activation, no setup pages or complex settings
* Native WooCommerce Integration – All settings appear naturally in existing WooCommerce tabs
* Lightweight & Fast – Minimal database queries, no performance impact
* Translation Ready – Full internationalization support

Real-World Use Cases

  • Beverage Industry – Sell 6-packs, 12-packs, or cases while tracking individual bottles/cans
  • Food & Grocery – Manage bundles like “3-pack yogurt” or “dozen eggs” with accurate unit tracking
  • Fabric & Textiles – Sell by the meter or yard, track in centimeters or inches
  • Wholesale & B2B – Different pack sizes (case of 24, box of 50) with proper inventory deduction
  • Product Bundles – “Starter Kit” with 5 items reduces inventory by 5 automatically
  • Multi-unit Items – Sock sets, furniture sets, or any product sold as multiples
  • Craft & Art Supplies – Sell paint sets of 12 colors, track individual tubes
  • Pet Products – Dog treat packs, cat food multipacks with unit-level tracking
  • Office Supplies – Pen packs, paper reams sold by case but tracked by unit
  • Subscription Boxes – Each box contains 8 items, inventory reduces by 8 per order
  • Compliance & Auditing – Full audit trail for inventory accountability and loss prevention
  • Warehouse Management – Track which orders depleted stock and when for better forecasting

How It Works

Stock Multiplier:
1. Set a “stock multiplier” value on any product or variation
2. Customer places an order for that product
3. Plugin calculates: stock reduction = ordered quantity × multiplier
4. Inventory is reduced by the calculated amount
5. Change is automatically logged to inventory history

Inventory History:
1. Every stock change is automatically tracked and logged
2. View complete history in the “Inventory History” tab on product edit page
3. See date/time, product/variation, action type, before/after quantities, order links, and user information
4. Add notes to manual stock adjustments for future reference

Example: A 12-pack of soda has multiplier set to 12. Customer orders 2 packs. Your inventory reduces by 24 cans (2 × 12 = 24), and the history shows: Order #123 reduced stock from 100 to 76 (-24).

Configuration

Setting Stock Multiplier

For Simple Products:
1. Go to Products > Edit Product
2. Click on the “Inventory” tab in the Product Data section
3. Find the “Stock reduction multiplier” field
4. Enter your desired multiplier value (minimum: 1)
5. Save the product

For Variable Products:
