Manager support submission of electronic documents in several countries via their localisation. In all cases I’m aware of this is done via the users submitting the Manager formatted data to a third party who then submit it to their government.
What companies offer this service in the UAE? Do they support cvs (comma separated values) file uploads? A local doing some research may increase the chances of Manager supporting UAE. I believe in the longer term such functionality will be generated entirely by local users writing localisation for Manager.
