WPC Shared Stock – Attribute Stock & Group Stock for WooCommerce

WPC Shared Stock is the ultimate inventory synchronization solution for WooCommerce. It seamlessly empowers store owners to share the same physical stock quantity across entirely independent Products (Simple & Variable) and dynamically across specific Global Attributes.

🎯 The Pain Point it Solves

In standard WooCommerce, every product and variation acts as an isolated inventory island. But what if you sell wine both as Single Bottles and as part of a Gift Basket Combo? What if you sell Coffee beans packaged in 250g, 500g, and 1kg bags pulled from the same giant barrel?

Keeping these separate product inventories manually synced is a nightmare leading to overselling and chaotic operations. WPC Shared Stock acts as the central brain orchestrating these shared pools.

🌟 Key Features

1. Dual-Layer Mapping (Direct & Dynamic)

Product & Variation Mapping: Manually map absolute combinations. Connect “Product A” and “Variation B” to the same shared “Group X”.
Global Attribute Mapping (Automated): No need to map 1,000 variations manually. Tell the system: “Any product using the Attribute ‘Color: Red’ shares this stock.” Any past or future variations matching that attribute will automatically tap into this shared pool!

2. Multiplier Logic (Consumption Ratios)

Not all items reduce stock equally. You can set customized subtract-ratios when mapping:

• Single Item: Multiplier = 1. Reduces stock by 1.
• 6-Pack Combo: Multiplier = 6. Resolves to the same group but reduces shared stock by 6 units per purchase.
• Wholesale box: Multiplier = 24.

3. Smart Fallback Calculation Engine

We do not just casually copy stock statuses; we accurately process the lowest common denominator. If a user tries to buy a “6-Pack”, and the Shared Group only has 5 physical items left, the “6-Pack” product dynamically evaluates itself as Out of stock while the “Single Item” still correctly shows In stock.

4. Backorder & Threshold Support

Complete compatibility with WooCommerce standard flows. Enforce backorder allowances independently per shared group, and trigger automated Low Stock alerts directly to your email before critical shortages occur.

5. Intuitive Overridden UI

When a product’s inventory is taken over by a Shared Group, the native WooCommerce “Manage Stock” input fields are safely locked, dimmed, and annotated with visual warnings in the backend to prevent accidental manual data entries from breaking the synchronized pool.

📖 Practical Use Cases

✅ Raw Materials Distribution: Sell raw fabric by the meter, but also offer pre-cut 5-meter curtains. Both draw from the exact same physical fabric roll in the warehouse.
✅ Hampers & Bundles: A “Christmas Gift Hamper” relies on physical inventory from independent stand-alone items like “Box of Sweets” and “Wine”.
✅ Print-on-Demand Blanks: You have exactly 100 blank white t-shirts in stock. You have 50 different graphic design products printed on white t-shirts. Map all 50 products using the Attribute: White to a single Shared Group initialized with 100 units.
