In July the company will release a suite of mobile applications that allow employees to check their pay statements, benefits and other data from a smartphone. Another app will let workers clock in and out from their phones, using geolocation data to make sure they are actually at work when they do so.

Then in October, ADP will refresh its entire suite of on-demand services to give them a more up-to-date, Web 2.0-style interface, CTO Michael Capone said in an interview Wednesday. It will also bring more integration to what are, today, a fairly disconnected set of services.

"When I meet with clients they tell me, 'We love your products, they're deeply functional, everyone gets paid on time -- but they look a bit tired.' And they're not as integrated as they'd like," he said.

The company aims to fix that with the October release, called Vantage. It will also start to sell analytics services that allow companies to see if, for example, they are paying their employees the going rate for their industry in their region. It can do this using the payroll data it manages for its 550,000 clients.

ADP, properly called Automatic Data Processing, sees itself as one of the original cloud providers, before that term became popularized. It stopped selling on-premise software about a decade ago and provides its outsourced services from two data centers in the U.S.
