Here's how to view a report of your Aged Debtors on FreeAgent.
They're customers who owe you money on a particular day, because you've sent them an invoice before that day and, as at the report date, they hadn't paid you.
From the Accounting menu choose Aged Debtors.

This brings up the Aged Debtors screen.
You can see that all the customers who owe you money are listed here.

You can choose which date you want to see this report at, from the drop-down menu on the right-hand side of the screen.

You can also change the dates in your browser if you wish.
For each customer there's a total of how much they owed you. The column headers (0-30 Days etc) tell you how long before the report date you issued that invoice.
There's also a breakdown of the total that each customer owes, by invoice. You can click the arrow by the customer's name to show or hide this information.

Be aware though, that if you have more than fifty customers who owe you money, you'll only see the totals, not the breakdown.
There's also a grand total of how much your customers owed you at the bottom of the screen.
It means you have even more information about who owes you money and can chase the laggards, so that your business won't run out of cash.
