I think what you're asking isn't possible, simply because all QB's reports are date driven. If you pull an Open Invoice Report to show what is outstanding as of your year end, it will not show any payments after the year end date. If you pull a report to show payments since the year end, it will also include any invoices charged to clients within that date range. The only thing I can think of is if you export your basic report to Excel, then add a column for the payments received since year-end manually.
The other option is to provide your accountant with two reports. One open invoice report showing your outstanding receivables at year end, and another to show all payments received since year end.
To get an accurate Open Invoice report as of your year end which matches your A/R balance in the G/L, make sure you click on 'Customize Report', then 'Advanced' in the lower right corner of the modify report window, and choose 'Report Date'. Otherwise, the report will not show outstanding amounts as of year end, but will only show outstanding amounts as of current date.
To get a list of all payments received since year-end for year-end amounts, pull a Customer Balance Detail report. Go to 'Customize Report', then 'Filters', then search filters for 'Transaction Type'. Choose 'Payment' from the list, or, if you want to show all customer credit items, choose 'Multiple Transaction Types' and then choose 'Payment' and 'Credit Memo' from the list. Enter the date range since your year end that you want to capture payments for.
