Our online store development at a glance

The individual components

Below you will find a brief explanation of the software we use and our recipe for success. We are convinced that a website is the flagship of a company. That’s why we invest as much time as necessary in the creation of your online store and think extensively about your business and your customers. Just click on the arrows to learn more.


The Foundation

There is no one solution for all. That is why we have three systems in our portfolio with which we can cover your requirements in the best possible way.

WordPress is the market leader in the field of content management systems, so it offers itself for many to expand your existing website based on WordPress to a store system.

Since there are no license costs and many third-party extensions exist through a large community, WordPress / WooCommerce is a possible store solution for all small and medium-sized businesses. 

Shopify requires less technical know-how than WordPress/WooCommerce to set up a store. It is very easy to set up payment methods and to couple marketing with the store.

For this, Shopify incurs costs in the form of license fees and a revenue share.

Shopify, like WordPress/WooCommerce, is a solution for small and medium-sized businesses.

Shopware 6 is the future of store systems “Made in Germany”.

Many online stores are currently running on Shopware 5 and will be migrated to Shopware 6 in the future. Shopware 6 is still young and therefore uses the latest technologies.

There is the possibility to host Shopware on-premise or in the cloud – we are happy to advise you which solution is right for you and implement it together with you.

Shopware is especially suitable for companies that need a good interface to an ERP system.


Our recipe for success

The approach is crucial for the success of a project – that’s why we are constantly developing here based on our experience.

Together we will discuss your wishes and requirements in our consultation and conceptualize your online store based on them. In doing so, we will give you our tips and tricks so that you can achieve the best possible result for your users.

After that we can make you a concrete offer that you directly know how good our price-performance ratio is.

We provide you with a project plan so that you can see by when you can expect the implementation of individual components as well as the entire store.

This way you will always know if the schedule is met and you can watch the changes live on our development page.

It is of great concern to us that the customer is fully satisfied with his shopping experience. For this reason, we also recommend the support of our experts, so that your online store remains sustainable, efficient and profitable.
