Salesforce announced the launch of a new “social help desk” called Desk.com in desktop and mobile versions.

“Desk.com and Desk.com Mobile enable businesses to deliver personal customer service using a help desk that is social, mobile, and easy to use and deploy: key attributes for any SMB today looking to leverage social enterprise technologies,” spokesperson for the company tells WebProNews.

“Desk.com gives companies a simple and affordable help desk they can use to engage customers on social media, email, chat, or phone,” she adds. “Even companies without IT staffs can get up and running over a weekend and for as little as $49. And, with the launch of Desk.com Mobile, companies can carry a help desk in their pocket and answer customers on the go.”

Desk.com is actually a product of Assistly, which Salesforce acquired in September.

“We built Desk.com so that every company can deliver personal customer service in a social and mobile world. Desk.com is social at its core; its mobile app instantly lets any employee, anywhere, deliver awesome customer service; and it can be deployed quickly and easily,” says Alex Bard, VP and GM of Desk.com.

It probably goes without saying that the product includes Facebook and Twitter integration (though no mention of Google+).

The mobile version is built with HTML5, and supports iPhone and Android devices.

Both the desktop and mobile versions are available today. Pricing starts at $49 per full-time agent, per month, for unlimited usage. Flex pricing is also available for $1 per part-time agent, per hour. The mobile version is free with the desktop version.
