Can I use the HPOS Compatibility Add-on for a WooCommerce Multi-Site setup?
The HPOS Compatibility Add-on works on a per-site basis—meaning it must be purchased separately for each WooCommerce site in a multi-site network. It cannot be used across multiple stores under a single license.
If you manage multiple WooCommerce stores, each store needs its own add-on license to prevent deal mapping failures and ensure smooth data synchronization. Unfortunately, bulk purchase options are not available at this time.
