KOS Design created our new website for Meinhardt's Bangkok office (www.meinhardt.net) and we have been very pleased with the results. The process of development a website that demonstrates our expertise and has a professional image was very interactive and rewarding.

Since it was launched late last year, we have received a lot of positive feedback from our clients and would recommend KOS Design to anyone else interested in setting up or upgrading a website for their business.

We've been working with many IT developers during the past years, none of which has come even close of reaching the high standards that KOS Design provided us with. From planning to execution and continues support throughout the development - they have been nothing but perfect.

The team has built us an amazing eCommerce platform, and continue to support and help us accordingly after completion.

We have finally found a partner we can rely on moving forward that provides us with the highest quality of services in the market in every single aspect of the IT side. Thanks KOS!

We chose KOS DESIGN with reference to the experience they display on their website and I was not disappointed.
The MD came to meet us personally and from then, it was a close partnership to the end. Good reactivity and service from start to the delivery of the finish product.
