AddressTwo CRM is a simple, usable and affordable CRM tool for small firms. Compared to bigger firms, customer relationship is more important in a large business. You cannot afford to take a blanket approach. You must treat every customer on a personal level. A CRM like AddressTwo helps create and build relationships, and also track relationships that matter the most. Since it’s a CRM meant to be simple, the user interface is quite straightforward and there’s no training required to get started with it. A little bit of guidance here and there would suffice.
