I am trying to send products to the US from the UK, using UPS to sell on amazon. My package was returned with reason "invoice missing from customs doc pouch." I am completing an invoice to attach but there is so much info required that I am not sure what to write.

Who's information should I put in the 'sold to' field?

What info is being asked for under 'total invoice amount'?

Where do I find the Purchase Order number?

Any help appreciated as I complete an invoice and attach it to re-send and hope it doesn't come back again!
