John Kittrell's Review Sourced from Google
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.
