Vtiger
Open source customer relationship management software is a key tool for helping companies to make the most of their existing customer accounts. A customer might not have made an order in a while, which could trigger a CRM tool to send an email encouraging the customer to come back or providing a special incentive for making another order within a certain time frame. The CRM tools made by Vtiger, a top ten open source CRM agency, also helps companies to market related products or services to their clients. For example a plumbing company working with the open source CRM software could use it to send out tips on maintaining clean drains or a discount on a related service, such as a faucet replacement. Vtiger provides consistent customer support for all of its software. Their software is easy for new users to get used to and provides a boost in sales.
