The Salesforce West Building in San Francisco. (Salesforce Photo) Salesforce plans to release some previously announced features and introduce a few new ones Thursday for its Sales Cloud product, hoping to stay atop the customer-relationship management heap by giving customers incentives to put more and more of their sales tactics inside Salesforce. Sales Cloud will soon give customers more flexibility over how they manage recurring billing contracts and sales managers more tools to manage inside sales reps, according to Salesforce executives. The company also plans to add machine-learning capabilities that it promises will help users of its Pardot marketing automation software better understand why their customers choose to be customers, and why they decide to walk away. The company is adding two features to its High Velocity Sales Cloud feature designed for inside sales reps, who do a lot of the grunt work and get less of the glory but are an essential part of the sales process inside many companies.
