IT Services Review from Stephanie Volk
Results Technology has provided us with the technology expertise we did not have internally. They are helping us create an overall IT strategy and have provided us with improved productivity and increased security and compliance. We are extremely pleased with their services and their friendly team. We love having access to the latest technology and IT best practices from a team that knows what they are doing. Not to mention the added benefit of predictability in terms of expenses.

Results Technology was great in helping me get my new laptop set up. They were able to transfer over files that I needed and get many of my daily programs configured so I could use them same day. Thanks!

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.

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.

So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis.

Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.
