I first check my bank account in case I need to mark an item as paid and then as I use click & send I just log in  and click on import ebay items and a list comes up of all items that are marked with cleared payment, I then go through them one by one, print the labels then parcel up each one matching the item number on the printed label to the item number in my sold items.

I then check in ebay to see if there are any with payment made which C&S have missed (happens sometimes)
