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.

Murali Krishna's Review Sourced from Google
I worked with Sunvera Software on the development of a fitness app for a business. Sunvera delivered the app on IOS and Android platforms. Their development teams were easy to deal with. The app had some complex workflows and Sunvera handled it easily. Weekly reviews kept the development pace on track and kept us informed on the progress.My 5-star review reflects my recommendation of Sunvera for anyone else seeking to develop a solution. However, a well thought-out review must also have identified room for improvement. My suggestion for improvement is their software-bug tracking and closure process to keep the customer better informed. There were times where this was lacking during our project. Team members compensated by stepping up and doing the needful.

Sunvera helped us develop an app for our product, HEYKUBE. They did an outstanding job, managing simultaneous iOS and Android versions, provisioning a backend server, and implementing core development for the app. The app incorporates graphics as well as a custom BTLE stack to communicate with our device. The team is great, and Ram provides steady leadership to make sure projects get done on time. I would highly recommend Sunvera to just get the job done for you.
