Receipt collection for Domeneshop
Cardboard automates the collection of receipts for payments made through Cardboard, so you don't have to collect the receipts yourself.
Receipt collection with email
Domeneshop sends receipts to a billing email.
All you need to do to automate the receipt collection is to add the Cardboard subscription's receipt collection email address as the billing email in the service.
Some services support multiple cards but only one billing email. In those cases, set the billing email to your general Cardboard email address.
Receipt fetching with browser extension
The Cardboard browser extension can upload the receipts for this service.
All you need to do is go to the page where you can download or view the receipts. The extension will let you know which of the receipts are missing from Cardboard and you can upload them in one click.
