Why do I get a notification saying that my registration number already exists? Follow

InExchange collaborates with several suppliers in the market. Some of these have their systems connected to InExchange to automatically send invoices directly in the system.

What then happens is that we get information from the system supplier that you are using a system that has such an option, these solutions can unfortunately not be combined but you must choose which solution you want to use.

Our recommendation is that you contact the system supplier and discuss the service you already have to send e-invoices. If you continue with this service you save to do double the work with first registrating the invoices in your system and then register invoices in our portal.


If you still want to use the services directly via InExchange please contact our support and we will help you with this.
