Wholesale and B2B stores often cannot accept an order the moment it is placed. Prices need a check, stock needs confirming, credit terms need a sign off, or a large order needs a second look. WooCommerce has no approval step, so the order is paid and marked processing straight away, and you end up refunding, cancelling and chasing customers by email.
B2B Order Approval for WooCommerce adds that step. The right buyers go through approval and everyone else checks out as normal, which suits mixed retail and trade stores.
