Hi @sharpdrivetek
You are absolutely correct, its a human error indeed, but the problem in our case is that we have a separate billing system which generates the invoices,
At the end of the day, we export the sales invoices in the form of excel and then transfer each and every invoices from the generated excel file to the “Manager” App.
The mediation is done through a dedicated person who is prone to make mistakes such as the one mentioned in this topic. What i feel is generally its best practice if the system is able to track duplicate invoices numbers and fire an error.
The perspective i’ve experienced is maybe just one of many views, there maybe more cases that’d relate to my request.
