Employee expense reports (Mitarbeiter-Auslagenabrechnung)

I would like to use InvoiceNinja to track expenses of employees and generate expense report invoices (German: Auslagenrechnung) for accounting purposes before reimbursing those expenses.
But when I turn an expense into an invoice, it is billed by the company to a customer - and I need to bill it by an employee (which could be entered in as a client) to the company.

Hi,

The app isn’t designed to work that way but maybe you could duplicate users as client records?

yes I could, but I still need to reverse the invoice - by the client to the company, not the other way around
