Olark makes the conversation with the customer effortless and easy. With a polite bubble ping, the employee is not only notified of incoming messages but also able to reach out to existing users that have yet to reach out. You can push the customer to certain pages as well as allow them to share their screen with you. Simple commands using a "!" at the beginning allow for automated responses created by the admin. Transcripts easily upload into customer management platforms such as SalesForce to allow for documentation practices to be upheld. Each chat offers an opportunity to review at the end. This can be monitored by the admin on the home page when the admin logs in. Low chat scores are easily identifiable. Should off-hours be present or they just barely miss an available agent, the chat is swiftly converted into an e-mail that requires follow-up by an agent.

Works best to support straight forward simple use cases.

Olark is by far the cheapest option out there. They get the job done.
