Creating a manual order from the WooCommerce admin is slow. The customer search misses phone numbers typed a different way and never lists past guests. Adding a product means a popup and a search with no prices. Shipping costs are typed by hand, and taxes only update when you click Recalculate. Advanced Manual Orders fixes the order screen you already use.
New orders open as drafts with WooCommerce’s own “Create” button, exactly like a normal new order. Drafts you never create are cleaned up by WooCommerce after a few days.
