Can I create multiple entities using the same TRN on different account?

In E-invoicing , you cannot have two companies with the same TRN because your TRN as I explained is connected to your TIN which is your participating ID on PEPPOL. Instead you can add other users as Editors.

So, whoever is using the primary account and has access to the main entity will need to go to the app portal, select the entity page where they would like to grant access, and add the relevant users from there.

Once a new user is added to the entity, they will receive an email invitation to accept the access. Please note that the user must have an account created 1st in order to receive and accept the invitation.
