Business software maker Salesforce.com yesterday launched a slimmed-down version of its customer-management services that existing customers will be able to access for free using high-end mobile phones.

The company that pioneered software as a service - managing customers' information and data remotely on a pay-as-you-go basis - said it could reach one million users with its new Mobile Lite service.

Salesforce already has clocked up 70,000 downloads of its Apple iPhone version in seven months by customers on its more expensive, all-inclusive packages.

Mobile Lite will be available to customers using Research in Motion's BlackBerry smartphones and phones running on Microsoft's Windows software as well as the iPhone, said Salesforce.

"The plan is to make it free. There is no plan to change it," added Salesforce chief marketing officer Kendall Collins.

Mr Collins said he hoped customers using the free service would be tempted to upgrade to more expensive packages that include more mobile functions.

Mobile Lite allows customers, typically corporate salespeople, to access some of their company accounts and data and update them in real time while on the road.

"We don't have a forecast for what's going to happen," Mr Collins said when asked how many people Salesforce expected for the new service. "It's going to really accelerate adoption. We think that the value of upgrading is going to sell itself."

Salesforce's offering is an example of so-called cloud computing, where customers connect via the internet to software and data held for them at remote centres - a model that is rapidly gaining momentum, partly due to economic conditions.

The model - used by Google, Amazon and Microsoft for some of their business - allows users to pay for software as they use it.

The traditional way of selling business software, practiced by Oracle and SAP, for example, involves companies buying expensive licenses and paying regular maintenance fees.

Technology research firm Gartner estimates the cloud-computing market, including Web advertising, will be worth €42 billion this year. Software as a service, the area in which Salesforce operates, is forecast to be worth €4.8 billion.

Salesforce, which expects to make sales of about €973 million this fiscal year, said yesterday it was approaching 10,000 customers in Europe this quarter, an increase of about 70 per cent from a year earlier.

Globally, Salesforce has more than 55,000 customers, including Allianz, Veolia Environmental Services and COLT Telecom, and more than 1.5 million individual subscribers at the companies who are its customers.
