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.

ISSA monthly meeting. Great venue. Good location. Extraordinary buffet at meeting. Interesting discussions.
Accenture goes the mile to support our meetings and I always enjoy working with their team. By the way the view of LA is incredible.

Rutledge Daugette's Review Sourced from Google
We had a great initial project with Ameex before they were purchased by Perficient. Post-support was slow, but acceptable, however as time went on, I stopped getting the level of communication and time itemization I was accustomed to. With Perficient taking over, things devolved pretty quickly, and despite multiple conversations with my account manager - nothing changed, even after bumping up hours to have more dedicated resources. Ultimately, I cancelled the contract this year. Disappointing because their team/work was stellar (and the development team is still solid) before, but the simple asks were continually ignored, and over time, I lost trust that I was getting the hours agreed upon.
Towards the end, there was also what felt like a lot of gaslighting of my concerns, and outside of an initial project, I cannot recommend Perficient for ongoing support.
Edit: I'm now bumping this to a 1 Star because I've spent the last 3 weeks digging into code and it's one questionable decision after another. Really poor.
