If you have payed your order directly, you will not recieve an invoice.
You will recieve an reciept of the order (order confirmation) to your email within a few minutes after the order has been placed.

If you have payed by invoice though Klarna or Paypal, the invoice is usually sent to the email address you provided at the time of purchase.

If you pay as an Business customer, you can write to our support at [email protected] in order to recieve an invoice! 

You are always welcome to contact us if you have any questions.
