The Analyse Debtors window allows you to view detailed information about the customers who owe you money and how long they've owed it to you. The window has three views. The information in them is based upon the entries you make in the Ageing Date - Analyse Debtors window found by clicking the Filters button.
This analysis includes all invoices and payments. To see your debtors account balances as at a past date use the Debtors Reconciliation report.
The Sale Detail view of the Analyse Debtors window displays all the transactions assigned to the sale that appears in the Sale Detail field for the customer whose name appears in the Customer Detail field at the top of the window.
