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.

We cannot say enough about this company. Manish has gone above and beyond on multiple projects including upgrading our ecommerce site. All of our issues were answered promptly and all of our projects were completed as quickly as possible and very efficiently. We look forward to doing more business with this company in the future.

If I could give more stars, I would. The team was very easy to work with, compliant, response time very quick, and they listened to what we wanted. I can't praise the Open Source Technologies team enough. We are more than happy with the results and give them the highest recommendation!

I am very happy to have found OpenSource Technologies. I had an issue with an existing website which was based on an old oscommerce platform and was running on a deprecated version of PHP. Because I have multiple sites I was unable to change platforms with my existing host or my site would go down. Therefore I needed to install a new Ecommerce platform and needed some development time without my site going down during that time. Both Vikas and Minash were great about installing my new platform OpenCart 3 and providing a temporary development server to build my site which was going to take a few weeks. They were knowledgeable as I navigated the the new platform and very responsive to questions and suggestions. I am happy with my new site which is now live and thank them for making the project a lot easier than I thought it would be. I highly recommend them and thank them for working on my project.
