Click on the link to 'See your purchase history in the App Store or iTunes Store' [mobile device, computer, or web] --> View your purchase history for the App Store, iTunes Store, and other Apple media services - Apple Support

- Does not include purchases made by others under Family Sharing; those have to be checked from their accounts.

- Web: "To see charges from older purchases, you might need to look at your purchase history in Settings or the App Store."

- iOS device or computer: If you want to see purchases that you made more than 90 days prior, "tap Last 90 Days, then select a different date range."

I you have suggestions for improvements, follow this link --> Product Feedback - Apple

I have seen others ask this and have yet to see a solution. Send feedback to Apple. You should, however, receive an emailed receipt for any purchase you make.
