Live chat is a common feature with some of these online support desks. For e-commerce businesses, live chat can be a powerful shopping cart tool for unsure customers. This feature can reduce cart abandonment rates and increase conversion by allowing customers to ask questions and resolve concerns. Popular solutions include Help Scout, Zendesk, and Groove, which offer monthly subscriptions with tiered rates depending on the level of service you require. You can also automate nearly every element of customer interactions, such as email, using a tool like Zapier.
