In complex scenarios, especially in the capital goods industry, sometimes there is no direct link between payments and invoices. You send invoices to your Customers and your Customer sends you block payments or payments based on some schedule that is not linked to your invoices.
In this tool, you can select an account (your Customer’s account) and click on “Pull Payment Entries” and it will select all un-linked Payment Entry and Sales Invoices from that Customer.
To cancel off some payments and invoices, select the Invoices and Journal Vouchers and click on “Reconcile”.
