Reports for an Accountant

Hi,

My Accountant has asked for a one-page monthly report which has an opening/closing balance so that he can check the feed FreeAgent is importing from Amazon is correct.

Apparently there is a report somewhere that shows this?

On the Payments dashboard, the summary reports are per every settlement period (which in my case is every couple of days). How do you get this report but by month rather than every time you cash out?

Thanks
