Online-Shop Development

3, 2, 1… Go! – Experiencing the launch of your own online shop is a very special experience.

_B2C E-Commerce

The optimal and permanent solution for the needs of our customers.

To sell online, it is not enough to set up your own virtual shop. A webshop is a large and complex digital project that takes time and continuously requires resources. The 426 team has extensive experience in this area through the development of a large number of successful, implemented webshops. 

Our software implementation style is based on established technologies from the world of e-commerce, be it for the flexible adaptation of a standard solution or for the personalized development of a web shop.
