Recently we encountered a ghost invoice that appears to be from the Dutch Chamber of Commerce. They referred to themselves as the Chamber of Customers, and were using a device that was very similar to that of the Chamber of Commerce. Fortunately the real Chamber of Commerce took immediate action, and prevented 350,000 invoices from being sent. Unfortunately 1.4 million invoices were already sent before this. The amount to be paid to the Chamber of Customers was € 149.- per invoice. It is estimated that one in ten recipients of ghost invoices actually pays them.
