Use this window to get an overview of each customer. You see general information for each supplier such as Supplier ID and name, current balance, and due amount. You can also view all ledger items for the supplier (including all the supplier invoices and supplier payments), with the relevant matching IDs that show the connections between the payments and invoices. Advance payments can be identified in this window, as it is possible to view which payments have been matched with the advance invoices.
