The Debtors Control account produces a summary analysis of the movement on the Debtors Ledger in the specified period.
Provisional invoices are not taken into account for the purposes of the report.
The Debtors Control Account Opening Balance reflects the Aged Debtor Balance at the start of the day. So if you want the Aged Debtor report to tally with the Debtors Control Account Opening Balance on 1 December 2009, you should run the Aged Debtor report for 30 November 2009.
