In my online credit card account, I can expand each purchase and "show digital receipt" to get information about what app/subscription it was for. For all App Store purchases, Apple will also email the account that made the purchase (even if it's me) to let them know the purchase details were requested. That seems reasonable to me--the payer knows what the payment was for, and the purchaser knows the info was accessed.
