I am set up as an agent but haven't registered as an agent for anyone yet (I have access to a lot of companies online through 'shared' log-in details). I want to set up as an agent for a client for payroll, but need to register the company as an employer too. Can this all be done online? It confuses me slightly that you can set yourself up as an agent for a client online as it suggests that you don't need the clients approval to do so....at least the agent form requires the clients signature.
