Contract managing service Apttus has raised a $41m series B round led by Salesforce.com, increasing its total funding to $78m.

Apttus, a US-based company that leverages Salesforce.com’s cloud platform to manage sales contracts, raised $41m yesterday in a series B round led by Salesforce Ventures, Salesforce’s corporate venturing arm.

K1 Capital and Iconiq Capital also participated in the round. Apttus previously secured $37m in a 2013 series A round also backed by Salesforce, K1 and Iconiq.

Apttus has developed an automated contract managing, or quote-to-cash, system native to the Salesforce1 platform that provides businesses with a complete service from quoting prices to interested buyers to completing the transaction and managing renewals.

John Somorjai, executive vice president of Salesforce Ventures, said: “Apttus’ leading quote-to-cash capabilities extend the value of the Salesforce1 platform. We are excited to help the company accelerate its growth and establish a new standard in how companies do business.”
