As you enter the Purchase Order Receipt (and also earlier on when entering the Purchase Order), ApeksOPS allows you to view the new Margin % and to update the Product’s Retail Price if necessary (i.e. the WooCommerce Regular Price). If you alter the WooCommerce Regular Price this will be reflected immediately in your online store. (Note: if you have a Sale Price set in WooCommerce, this will not be affected, and will stay in effect).
