How Do I Move an Item From One Invoice to Another?

Lots can be moved from one unpaid invoice to another by clicking on the arrow icon to the right of the desired item:

From the subsequent menu, select the name of the bidder whose invoice the item will be moved to:

Once the bidder has been selected, clicking 'Move Item' will move the item to the destination invoice. Please note that only bidders registered to the same auction can be selected; if the bidder is not registered for the auction, you'll need to register them, then carry out this process.
