Who needs Attribute Stock Manager for WooCommerce?

If you sell product variations with shared elements, parts, or ingredients (attributes) you will benefit from simultaneously tracking the inventory of products and their attributes.

For example, a t-shirt seller who prints various designs on plain t-shirts needs to know how many plain t-shirts they have in inventory. Their stock of plain t-shirts decreases as they print and fulfill customers’ orders for printed designs.

The seller needs to track sales of the variations (assorted printed designs) and the plain t-shirts that designs are printed on (attributes).

Attribute Stock Manager for WooCommerce gives sellers the ability to track the stock of products and their related attributes.

Benefits

Better inventory management

You can easily manage the inventory of products and variations that require inventory sharing.

Increase purchases and prevent backorders and out-of-stock issues

Generally, when a product or variant is out of stock in a particular size, the user will wait until that exact item is available again to purchase. When inventory syncs between products, the users can see what else is available and purchase from all available products associated with the global inventory.

How does it work?

Stock sharing across variations

Once admins configure stocks and attribute stocks, the extension will be ready for use. All the variations associated with the attribute will share the same global inventory.

For example

You sell ground coffee and fill your coffee-powder orders from the same central supply of coffee powder (the attribute). With each order of any size, you diminish the total supply of coffee powder.

When a variant is purchased (for example, 250 grams of coffee), the purchased inventory updates the attribute inventory. Customers see the change across all the variations that share the inventory.

Stock sharing across products

Once admins configure the stocks and attribute stocks, the extension is ready to use. All the products associated with the attribute will share the same global inventory.

With each product purchase, the stock will update the attribute inventory. The change will also reflect across all products sharing the inventory.

If a user tries to purchase products beyond the available inventory, Attribute Stock Manager will prevent them from over-purchasing and show them the quantity available.

Attribute Stock Manager for WooCommerce prevents overselling and encourages customers to purchase available inventory instead of waiting for an out-of-stock product.

By tracking attribute inventory, Attribute Stock Manager relieves stress on store owners and increases customer satisfaction.

Popular Features

1. Shared Inventory Pools Across Products

Link products that share the same attribute value like a fabric, color, or material used across multiple products to a single shared stock pool, so selling any one of them draws from the same inventory.

Key Capabilities:

• Create dedicated Attribute Stock records with their own SKU, stock count, and status.
• Stock automatically shared across every product or variation tied to the same attribute value.
• Notes field on each stock pool for internal reference.

2. Attribute Groups & Matching Rules

Define exactly which attribute/term combinations feed into a given stock pool, with support for matching specific values or any value of an attribute.

Key Capabilities:

• Attribute Rules mapping a specific attribute + term to a stock pool.
• “Match Any” option to apply a rule across all terms of an attribute.
• Multiple groups per stock pool, each with independent matching logic.
• First-matched-rule priority when a product matches more than one rule.

3. Quantity Multiplier per Group

Account for products that consume more than one unit of shared stock per sale (e.g., bundles or multi-packs).

Key Capabilities:

• Configurable quantity multiplier per attribute group.
• Multiplier automatically applied during stock deduction and restoration.

4. Backorder & Low Stock Management

Manage stock pool availability with the same flexibility as native WooCommerce inventory controls.

Key Capabilities:

• Backorder support at the shared stock level.
• Independent low stock threshold per pool, separate from global WooCommerce settings.
• Stock status control: in stock, out of stock, or on backorder.

5. Product, Category & Tag Filtering

Control exactly which products participate in a shared stock pool using flexible include/exclude filter rules.

Key Capabilities:

• Include or exclude by product category.
• Include or exclude by product tag.
• Match-all-groups toggle to require every configured group to match before stock is shared.

6. Per-Product Opt-Out

Give individual products the ability to bypass attribute-based stock sharing entirely.

Key Capabilities:

• “Ignore Attribute Stock” checkbox directly on the product’s Inventory tab.
• Product reverts to its own native WooCommerce stock management when ignored.

Keep shared stock pools accurate through the full order lifecycle — no manual adjustment needed.

Key Capabilities:

• Automatic stock reduction when an order is placed.
• Automatic stock restoration on cancellation or refund.
• Restocking on refunded line items, and safe handling when order items are edited or deleted.

8. Seamless WooCommerce Core Integration

Shared stock pools behave exactly like native product stock everywhere in the store.

Key Capabilities:

• Overrides core stock fields (manage stock, stock quantity, backorders allowed, in-stock status, sold individually) at both product and variation level.
• Cart-level validation prevents adding more than the shared pool has available.
• Fully compatible with WooCommerce Cart and Checkout Blocks.
• High-Performance Order Storage (HPOS) compatible.

9. Automated Email Notifications

Keep store admins informed the moment shared stock needs attention.

Key Capabilities:
