I would like to request client outstanding balance summary and details reports.
It should show total outstanding balance for a customer as of specific date. Customer payment report doesn't work because it requirs the date range so you need to make sure to include ALL days and this in turn produces the list of all the customers including those with 0 balance outstanding.
I like the option in QBO where you can select current or report date aging method. So I could see for example all outstanding invoices as of the last day of the last month that were not yet paid as of now.
