Could be different in your country, but here in Norway there wouldn't be an invoice in the box. The whole idea is that payment is totally separate. Email invoice or separate invoice per post, unless you pay immediately when ordering.

The shop you ordered from does not know or care how the transaction is done between you and Klarna.

Quite honestly I don't care enough to give it another try. Credit cards work just fine.
