Your QuickBooks subscription invoices are sent via email each month, Simon.
In the "View payment history " section of your account, you should have access to your full billing details, which you can easily download as a PDF file. For more information, please refer to this article: QuickBooks monthly subscription invoice.
Since you're unable to see the download option, let's refresh the page. After that, log out of your QuickBooks account, wait for a few moments, and then log back in.
If there's anything else you'd like to ask, add it to the comments, and we'll assist.
