InQ, a Los Angeles, Calif. company that provides online chat customer service for companies’ web sites, said it has raised another $5 million in a fourth round of capital.

We wrote about this company here, explaining how it pops up a chat screen on Web sites to handhold customers through their purchase decisions. It provides the service to any company that wants it, and gets paid only when products are sold.

The financing was led by Emergence Capital, and included existing investors Partech International, Dolphin Equity Partners, and Hudson Ventures.

The company says it has helped a Fortune 1000 company improve online sales by 20 percent in three months, citing a Forrester Consulting study that inQ commissioned.
