Well if you have posted the item why do you need to edit the handling fee on the invoice? You send the invoice before you get paid therefore before you post the item? Anyway too alter the postage you use the + and - tools on the invoice to add or subtract, so in your case use the + symbol to add the postage you want then click preview to make sure its right before you send the invoice. You cannot alter the invoice after the buyer has paid.
If it s on a sold item you CANNOT edit the handling fee. If it s an item that is currently running and there are bidders on it, you CANNOT edit any of that. If it s running and has a flat rate for shipping you cannot add an additional handling fee. If it s calculated shipping you can to to revise and click change under the handling cost and a new window will pop up to change it. Make sure there is an actual price in there including dollars AND cents, then click to save. If it s not working after that your best option may be to cancel the listing, edit the changes you want and relist. You may also be able to change browsers (Firefox / Internet Explorer) and try changing it under the different browser. Sometimes there are glitches between eBay software and different browsers.
Ebay have changed the rules on p p costs. For many items such as media (CD s, books etc.) you can t charge for p p. This makes it almost impossible to sell items that are 99p or less. If you build the p p costs into the starting price then you will incur an insertion fee. If the item doesn t sell in the first two attempts you will loose money.
