      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. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

      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.

      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.

      I they do not care about their customers!I have been with them for over 40 years! I was just notified I was no longer wanted as a client.I called and text 3 people I knew there, asking why they were canceling my simple tax account.NO ANSWERES. Then a month later I got an email saying they were down sizing!Is this how you treat a loyal customer of over 40 years that does a simple tax return? I always relied on this company and the people in it. I feel so disrespected. I would never trust them again.

      Computer technology has vastly improved many of our lives, even in the non-profit world. The issues are cost, reliability and maintenance. It is too much for a small business owner to become an expert in these areas. I'm not even sure it is possible. Having a partner - a paid vendor, yes, but a still a partner that respects your budget, responds quickly to problems as they arrive, and proactively seeks to protect your network from crashes and malware is invaluable. We feel like we have that partner with Whittlesey Technologies. Every year we meet to discuss vendor agreements and performance. Whittlesey Technologies has never been considered for replacement. They are our partner.
