I don’t sell on eBay, but my favorite bulk editing program - Vela - just rolled out an eBay version. I use it for Etsy & Shopify.
I have no reviews of the eBay one, but if you could use a bulk editor, I highly recommend - it’s something I’ve used for years & saves me so much time.
Can Vela handle multiple marketplaces at once (push adds/edits/deletes simultaneously to multiple channels)? Is it now being available enough to make you think about eBay?
You switch between platforms when you’re in it. I think there’s some sort of cross-platform syncing but I don’t use it since it doesn’t apply to me. No eBay for me - I sell art, I don’t think it’s a good option there.
Ebay’s bulk editing functions are more than adequate for my needs, and relatively recent charges like the creation of shipping policies have reduced the need for some common bulk editing like raising prices for fixed price shipping.
