Adding that I would like this feature added as well. The Quickbooks Extension that is mentioned as a solution does not work well because it cannot automatically import service-based products into quickbooks from squarespace. It also does not handle payment processor fees well.
I use the Acodei connector instead, but need product information added to the "Description" field in Stripe in order to do product mapping in Quickbooks.
When customers place orders through Acuity Scheduling and pay with Stripe, the product name as well as the customer name is added to the Description field in Stripe. This works very well and is what is needed for Squarespace products as well.
