Sugar CRM is perhaps the best choice for small businesses and startups trying to find their way in the foggy and often misleading world of customer relationship management software. With so many options out there, it can be hard to know who to trust. Sugar CRM is often rated the top piece of software in the industry, and there are several reasons why the customers have spoken in such a decisive voice. Sugar CRM is entirely open-source, which means it can be totally customized and changed to meet the specific criteria of any business. Not only is the software incredibly flexible, but it gives small startups the opportunity to compete on the same level as larger established businesses. This is because Sugar CRM also offers a software suite for enterprise-level brands, and that range of market research gives them a unique perspective on the world of customer relations management software.
