OPERATIONAL BREAKDOWNS

Why Default WooCommerce Stock Timing Breaks in Production

By default, WooCommerce couples inventory reduction to order creation or payment complete triggers. For stores with delayed wire payments, manual fraud review, or warehouse staging, this inflexible logic creates severe operational friction.

01

Premature Deduction on B2B & Wire Transfers

Net-30 or invoice orders lock up warehouse inventory before purchase orders are confirmed. If the invoice expires, stock was blocked for real paying customers, directly costing you sales.

02

Warehouse Staging vs Payment Confirmation

Stores managing physical fulfillment staging need stock reduced only when orders enter a custom staging status, not at initial checkout. Default WooCommerce provides no status-level configuration.

03

Ghost Stock on Unpaid Order Cancellations

When an unpaid order is cancelled, default WooCommerce code can inadvertently restore inventory that was never deducted in the first place, artificially inflating your warehouse count.

04

Multi-Status Double-Deduction Risks

Moving orders through intermediate statuses (such as Processing → Dispatched → Completed) risks duplicate stock deductions unless an explicit idempotency safety check is enforced.

ENGINEERED FOR PRODUCTION

Surgical Precision Across Every Product Type

Built to integrate cleanly with WooCommerce core without introducing custom database structures or conflicting with existing extensions.

STORAGE ENGINES

HPOS & Classic Storage

Declares explicit compatibility with High-Performance Order Storage (HPOS / Custom Order Tables) while maintaining fallback compatibility with classic wp_posts storage.

MATHEMATICAL SAFETY

Protected Against Duplicate Reductions

Every status change verifies the native _order_stock_reduced order metadata flag. Moving between multiple reduction statuses (e.g. Processing → Completed) protects against decrementing inventory twice.

VARIABLE PRODUCTS

Variation-Level Stock Accuracy

Correctly decrements and restores stock for variable products whether stock is managed at the parent product level or individually on each variation.

REFUNDS

Respects WooCommerce Partial Refunds

Correctly accounts for line-item refund restocking. If an order with partial refunds is subsequently cancelled, only the remaining unrefunded units are returned to stock.

GHOST STOCK PREVENTION

Prevents Phantom Restorations

Cancelling or failing an order that never reduced stock (such as an unpaid order on hold) will not increment warehouse inventory.

EXTENSIBILITY

Custom Order Status Discovery

Any custom order status registered through standard WooCommerce filters (e.g. wc_get_order_statuses) is automatically detected and populated into selection lists.

PERFORMANCE

Zero Custom Database Tables

Saves settings in 3 standard wp_options entries. Creates zero custom database tables and cleans up all options on uninstall.

MULTI-SITE

WordPress Multisite Compatible

Compatible with WordPress multisite installations. Each subsite on the network configures and maintains its own stock rules independently in its WooCommerce settings.

Configuring your inventory rules takes less than 60 seconds inside WooCommerce › Settings › Products › Stock Rules.

QUESTIONS & ANSWERS

Frequently Asked Questions

Practical answers to common merchant and technical questions.

No. The plugin includes built-in idempotency protection. It checks WooCommerce's native _order_stock_reduced order metadata flag before taking action. If stock has already been decremented, subsequent matching statuses simply confirm the state without reducing inventory again.

Yes. The plugin is HPOS compatible and declares explicit support using WooCommerce's FeaturesUtil::declare_compatibility API. It functions identically whether your store uses custom order tables or traditional WordPress post storage.

Yes. Any custom order status registered through standard WooCommerce filters (e.g. wc_get_order_statuses) is automatically detected and populated into both the Reduce and Restore status selection lists.

The plugin natively inspects line items via standard WooCommerce CRUD methods. If a variation manages its own stock, the individual variation's inventory is decremented or restored. If stock is managed at the parent variable product level, the parent stock is updated accordingly.

When partial refunds are processed in WooCommerce, core handles restocking for selected line items. Our plugin respects those adjustments so that if the order is subsequently cancelled, only the remaining unrefunded units are returned to stock, avoiding inventory overcounts.

In default WooCommerce, cancelling an order can inadvertently restore stock that was never decremented, creating phantom inventory. Our plugin verifies whether stock was actually reduced for that order prior to executing any restoration logic, preventing ghost stock.

No. The plugin stores its configuration in standard WordPress wp_options. It creates zero custom database tables, zero background cron queues, and deletes its options cleanly upon deletion.

Yes. Your license includes use on local development domains (e.g. .local, localhost, .test) and staging environments (e.g. staging.yourstore.com) alongside your single production domain.

Because the plugin is 100% GPLv2 software, it will continue to function on your store indefinitely. An active commercial license is required only for automated software updates, compatibility patches for future WooCommerce releases, and direct technical support.

Yes. The plugin integrates directly with native WooCommerce actions and filters (such as woocommerce_order_status_changed and woocommerce_payment_complete_reduce_order_stock) and provides opt-in debug logging to WC_Logger under WooCommerce › Status › Logs.
