Inventory update with supplier Excel list

Hi everyone,

I hope someone help me with this Problem:
I become a list of 600 products from a supplier every 2-3 days as an update to his inventory.
I am dealing with him per dropshipping-methode. Can anyone tell me how to upload this list to my ebay/online shop effectively and what information must the list include? How can I also change the price into mine?
I did some research in google but it seams complicated.
I wonder how some of you deal with this ? How you place the order in your supplier system ?
Do you need any software?

Note: I am talking about 600 - 1000 different products and not just few.

I will be more than happy if someone share with me his experience.

Best Regards

Hello qwertz,

While reading your post only one thing comes to my mind - Link hidden: Login to view

Turbo Lister is free, easy-to-use software that helps you create multiple item listings all at once on your computer and upload them to eBay. You can download the software from the Link hidden: Login to view.

Turbo Lister is designed for medium- to high-volume sellers.

Hope this helps you with your eBay store's product listings/updates.

Cheers!
