Hi bak2bakmarketing,
Welcome to Auctiva! Our service provides a robust set of listing and management tools so, if you are taking full advantage of Auctiva, you should be able to do just about anything you would normally do through your eBay account through your Auctiva account. However, using Auctiva will not change the functionality of your My eBay page, so you will still be able to do whatever you'd like through your My eBay page as well.
When you list items through Auctiva, you are still responsible for paying the standard eBay fees, however, you can save quite a bit of money when listing through Auctiva through the use of our free cross promotional scrolling gallery, free unlimited image hosting, free templates, free scheduling, free super-sized images, integrated checkout, and more. You can also place as many images as you'd like in each listing through Auctiva without being assessed any additional image fees by eBay.
The delays in listings showing up in eBay's search results pages that other have mentioned are actually not associated specifically with their use of Auctiva. When you post listings to eBay, depending on the details of your seller account and the types of items you are selling, it may take a few hours from when your items are posted for them to show up on eBay's search results pages due to eBay's "indexing" procedures. Additional information on this topic is available on the following page of eBay's help index: http://pages.ebay.com/help/find/questions/wheres-my-item.html
Any additional questions or concerns? Please feel free to contact our customer support team using the appropriate link on our help page: http://www.auctiva.com/free-auction-software-help/help.aspx
