Product Details On the Receipt on SS or Stripe

I only sell a couple digital downloads from time to time from my SS site.

I had an order for an item and I could not see what the item was for. I sort of knew but I wasn't for sure. So I started digging for info on Stripe and on Squarespace orders. There is no item name or description on the receipt. Where do I add more info that can show up on the receipts? I viewed the receipt on Stripe and there's nothing about what they ordered. Just the cost. I don't know if it's a Stripe issue or SS. 

I have the same curiosity. 
I see that I can actually create my products through Stripe and connect them through links and coding that way, but I wish there was a guide on this to insure that it is done properly.
