Welcome Bonnie-Jean,
Yes. When you create a listing in Auctiva, at the very top under Create an eBay Listing, click Store Item. Your listing will then go straight to your eBay Store. Be sure to import your eBay Store Categories to Auctiva first so you can choose which Category it ends up in (Go to: My Account>eBay Settings>Update Store Categories from eBay).
