To define specific localisation settings for one (or some) of your clients, you have to create a new document configuration (under Settings > Document and email configuration) and define these settings in the Settings tab of your new document configuration.
As name for this new document configuration, you can use the name of the client it will apply to, or any other name of your choice.
In the Settings tab, you can see a preview of how the dates and numbers will be displayed based on your selection. You can also select an option to display the currencies as a three-letter code instead of a symbol (so EUR instead of €).
Once you've created your new document configuration, don’t forget to go and select it for each client concerned in the details of the client, so that this document configuration and these localisation settings can be used for all your future documents for this client.
