Client default settings
From Protemos Wiki
Client default settings page: http://cloud.protemos.com/client/change-default?id=ХХХХ (replace XXXX with a valid number)
On this page, you can change your client's default currency, payment conditions, and language of invoices:
Note: Payment methods can be created in Payment methods settings.
PDF locale
By default, the system uses the language of invoices entered in the "Default settings" of your account whenever clients' invoices are generated.
But 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.
