The invoice is generated automatically by Amazon once the order status changes to Complete (after payment is confirmed). If your order is still Pending, please wait until it is paid and fulfilled.
If the invoice does not appear in your account after the order is Complete, you can:
— Contact Amazon Customer Support via Amazon.com/contact-us (for US; for other countries please use the correct domain, for example Amazon.ca for Canada, Amazon.co.uk for UK).
— Or email us at [email protected] and include your Order ID.
We will do our best to assist you with the issue.
