Salesforce.com Inc. on Tuesday introduced a new e-commerce service based on its $2.8 billion acquisition of Demandware Inc. in July. The Salesforce Commerce Cloud is intended to help customers set up online storefronts and in-store tablets and kiosks, adding commerce functions to the company’s portfolio of software delivered as a service over the internet.

Salesforce will need to adapt Demandware’s software to accommodate sales from one business to another, said Gene Alvarez, managing vice president at Gartner. For instance, the new service will need to tie in to corporate procurement and purchase order systems, he said. It doesn't yet have these features.

By 2020, the U.S. business-to-business digital commerce market is expected to top $1.1 trillion from $780 billion in 2015, a compound annual growth rate of 7.7%, according to Forrester Research.
