PDF locale
By default, the system uses the language of invoices entered in the "Default settings" of your account whenewer clients' invoices are generated.
Here you may define the language of invoices only for this particular client.
Note: The PDF locale setting entered in a client's profile overrides the default one entered in the "Default settings" of your account.
