Rishi Kumar Sr. Servicemax and Salesforce Developer at Boston Scientific
4.7★
Salesforce Review from Rishi Kumar
I had the opportunity to work with Accenture on implementing Salesforce with ServiceMax. Their expertise and dedication were impressive. Accenture's work on implementing Salesforce and the ServiceMax managed package was invaluable, significantly benefiting our organization's operations and efficiency. However, one area for improvement would be the documentation process. It was challenging to access comprehensive documentation, which slowed down certain aspects of our project. Nonetheless, I recommend Accenture as their talented team delivers exceptional results.
