The details showing in the Debt Report are all based on the invoices you have sent in Famly and the payments you have added to Famly, as well as any Famly Pay payments that have been processed. The invoices appear in the month they were sent in, not the period they are invoicing for.
Below the graph you are able to filter for bill payers with outstanding debt, by payment method, as well as search for a specific bill payer. In order for a bill payer to appear in the filtered payment method list, that payment method must be made automatic via Famly Pay.
The table is organised alphabetically by Bill Payer name and gives details for the previous 3 months. You can click into the invoices for each month to see the details. Additionally, the table shows total outstanding, overdue and 30+ days overdue, as well as the balance of the bill payers account. To quickly find a specific child or bill payer you can use the search box.
Famly doesn't offer a print option because the figures in the report often change due to new invoices and payments, but if you really need to print, just hit CTRL (or Command) + P on your keyboard.
