WooCommerce Role-O-Matic
The WooCommerce Role-O-Matic plugin (WCRA) is a powerful tool that allows the shop admin to create “assignment rules” that dynamically assigns roles to the customers according to the amounts spent during the configured time periods or according to the purchased products. This tool can be very useful because can be used together with the WooCommerce Pricing! (or any 3rd party plugin) to assign dynamic prices or discounts according to the assigned roles.
