GSP Do I wait until the buyer has paid?

[nicolehlyon]

Hi!

I have 2 items that I recently sold as part of the Global Shipping Program. It still shows that payment is not completed - and I can not send an invoice as it indicates that is not available through GSP. Do I just wait until it shows payment is received and then I send it to the US GSP Hub?

Thanks for your help!  I read through the help pages and it wasn't clear to me and just wanted to make sure I wasn't missing something.
