WPC Shared Stock

WPC Shared Stock is built for WooCommerce catalogues where several listings represent the same physical inventory. Instead of maintaining separate quantities for each product or variation, the plugin links them to a shared stock source and synchronizes the available quantity across the mapped items.

Shared inventory model

The central idea is straightforward: create a stock group, then connect products or selected variations to that group. This fits stores that sell one item through different listings, package formats, or attribute combinations. A sale against one mapped item affects the common inventory rather than leaving the other listings with an outdated quantity.

That arrangement addresses a specific operational problem. Without a shared source, an administrator has to update several product pages after stock changes, with every extra listing creating another opportunity for an incorrect quantity or an oversell. WPC Shared Stock puts the quantity in a group that the mapped products use together.

Mapping products and variations

The mapping tools provide two levels of control. Whole products can be linked to a stock group, while individual variations can be selected when only part of a variable product shares inventory. That distinction matters for catalogues where one colour, size, or other variation uses the same physical item as a listing elsewhere, but the remaining variations do not.

• Create centralised shared stock groups.
• Map multiple products to one inventory source.
• Map specific variations rather than an entire variable product.
• Use global attribute mapping to connect selected terms to stock groups.
• Apply ratio multipliers when one sale consumes more than one stock unit.
• Review backend and frontend stock changes through audit logging.

Global Attribute Mapping is listed as a Premium feature. Its purpose is to map particular attribute terms to stock groups without creating duplicate products, which gives larger catalogues a more compact way to express shared inventory relationships.

Ratios and audit history

Ratio multipliers extend the model beyond a simple one-sale, one-unit relationship. A pack that consumes six single items can use a multiplier of six, so the shared stock group represents the underlying physical units rather than the wording of the product listing. This is useful for stores selling singles, packs, or other formats from the same source.

The audit logging feature records stock modifications made on the backend and frontend and presents them in a dedicated interface. That record gives administrators a way to trace changes while reviewing stock behaviour, rather than relying only on the current quantity shown on a product screen.

Where it falls short

The plugin introduces a stock-group and mapping layer that an administrator has to design and maintain. Stores with a small catalogue and no duplicated inventory have little reason to accept that extra structure; the benefit appears when multiple products or variations genuinely draw from one source.

Attribute-based mapping is also separated from the core feature list as a Premium capability, so the most flexible approach is not available in the same form as basic product and variation mapping. Ratio multipliers add another configuration responsibility: an incorrect consumption ratio would represent the physical stock inaccurately. The supplied details also do not describe safeguards, reporting depth, or how conflicts between mappings are handled, so those points need checking against the store’s workflow before adoption.

Who it suits

WPC Shared Stock suits WooCommerce shops that sell the same stock through several product pages, variable-product combinations, or pack sizes. It is particularly relevant when one physical item appears in both individual and grouped formats, because the ratio feature accounts for different stock consumption while the shared group keeps the source quantity together.

Stores with straightforward, one-to-one product inventory should find the concept unnecessary. For catalogues with repeated listings and a clear need to avoid manual quantity changes, the combination of group mapping, variation selection, ratios, and change history provides a focused inventory-management layer.
