The Product SKU Generator for WooCommerce is a free WordPress plugin that simplifies the process of generating stock-keeping units for WooCommerce products. It automates SKU creation for both parent and simple products, including variations, whenever items are published or updated. This functionality is particularly beneficial for store owners seeking to enhance their inventory management by maintaining organized and consistent SKU assignments.

Key features include the ability to customize SKU formats based on product slugs or IDs and the option to perform bulk updates on existing products. Users can selectively enable or disable SKU generation to prevent overwriting existing SKUs, and they can manually assign SKUs for simple or parent products while allowing the plugin to manage variations. This level of control, combined with automation, makes it a powerful tool for WooCommerce users.
