I thought this plugin would actually split my orders (for e.g. – A customer makes an order that contains one In stock product and one Backordered product) so that the In stock product would be on one order and the backorder product be in a seperate order but instead it just adds a label in the orders page in Woocommerce as the order as a single order, simply titled ‘Backorder’.
It seems I need an actual splitter and partial shipment plugin for my needs.I’ve since deleted this plugin. Hopefully they can improve the features in future,
