Customer relationship management, otherwise known as CRM, is an important part of any business. However, keeping track of a company’s contacts by hand can get to be time-consuming and messy. This is why most people use software for that purpose. However, typical CRM programs can get to be expensive. Vtiger CRM is a great solution to this. It has all the features you’d expect from CRM software, and because it’s open source, it is much cheaper than commercial programs. Even in its free version, it can meet the needs of many companies. It also has the option of vtiger customisation. That way, even if it doesn’t quite have everything you need, you can modify it so that it does.
