Where can I see which parents have paid?
The Overview page will show the invoices that are outstanding, which means that if the parents are not listed on that page, they have already paid for their invoices. To find the payment details, you can go to the Transactions page or that parent's Family Ledger to view the information.
To view all parents that have paid, you can apply a filter on the transaction page to view only the payment details.
After you have altered the filter, then the transactions page will only display parents that have paid.
