Hi Andre,
Thanks for submitting this idea.

The Transaction Description will display "Shopping Cart" for orders placed via cart.php. Subsequent invoice payments will have the relevant invoice ID. This is due to the way the Stripe Elements API works; the client submits their card details directly to Stripe on the checkout page, creating the Payment Intent before the invoice exists. In these cases we set the description "Shopping Cart" so you can identify the source on some level.
