Receipt collection for Google Ads
Cardboard automates the collection of receipts for payments made through Cardboard, so you don't have to collect the receipts yourself. Some services, like Google Ads, do not offer to send emails with receipts, so Cardboard solves this with a browser extension.
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.
Since Google Ads has different billing URLs for different accounts Cardboard stores the urls on your subscription. This enables the extension to take you directly to the right page after you have done the first upload.
