Here is the procedure to return the invoice to a member.
Click on the Transaction tab in the member's profile
Click on the Action button in the right side panel
Click on Resend Invoice
A Success message will appear at the top of the page indicating that the email has been sent.
It is also possible for the parent to access these invoices in My Account.
The parent must go to the Purchase tab in My Account and click on the printer next to a partially or fully paid transaction to print a copy of the receipt that they normally receive by email.
