mightymacros Dat add-in is designed to identify uncaptured duplicate invoices before they become duplicate payments.

If you are looking for a tool that digs deeper to find duplicate invoices and payments, then you have come to the right place. ERP and accounting systems are often heavily relied upon as a backstop, and users rarely understand or question system logic. Large systems, in general, are not specifically designed for detecting duplicate invoices. These systems may provide some assistance, but there are limitations, and duplicate invoices will pass through their safety net. Invoice document information is not always clear and consistent. At times it can be difficult to read and process, resulting in mistakes on entry.
