[otrs] Different URL, logo and name for different customers

Hi list, I'm new to OTRS. Presently I'm using otrs5. this is my question. If I have three companies as customers to various of my products. How can I have a different customer.pl page for each one of them. Such that a customer user wants to post a ticket He accesses a unique URL and the page which is displayed to him has his company logo and company name. How can I achieve this?
