I listed my shirts onto Ebay about an hour ago. When I go onto my ebay account I do not see the shirts listed in my sellers account. Does it take a certain amount of time before my items will appear on my ebay account? Will my shirts even appear on my ebay account?

Short answer: immediately.

Long answer: your account needs to accept the international selling agreement. Post an item individually (not using the bulk uploader) to see the error. You can google for the link, or follow this link (that came in your error message):

I am a new seller to ebay. So I had to load my shirts onto ebay manually. It took some time but the only problem I am having now is the customers can't pick sizes or colours. is there a way to do this manually? maybe i am missing something

Selling with a new ebay account is hard. You're only given 10 variations a month to list. So listing 1 shirt with 5 sizes means you can only list 2 shirts.

See how variations work here:

You have to sell more and maybe contact eBay to raise limits.

You can list with sizing through tshirtgang by adjusting the quantity available to 1 or greater (also counts towards variations) and selecting which sizes you want to list.

Thanks for the response. I have been reading all day and learning the ropes. I've already had two people message me why I don't have sizes available and colours. I just need to make a few sales and then move onto ebay pro
