Why Sitewerk is the Best Provider for Web and Mobile Apps

Individual Solutions

Sitewerk apps and portals are always individually tailored to your company and your needs. We focus on your customers or the users of the new software and develop solutions with an excellent user experience. No solution is like the other, which sets us apart from industry solutions and off-the-shelf software.

All from a Single Source

With Sitewerk you get a complete, executable, digital solution. We advise you during the first steps and the definition of a possible project. Together with you and your customers, we work out the requirements that the app must meet, implement the first design prototypes, which are immediately tested by the end customer, and implement your app solution. Yes, we always work agile and iterative.

State-of-the-Art Technology

We live and love modern technology and are therefore always up to date with regard to trends and innovations. We use this knowledge every day in the development of web applications. In order to stay on the ball, our employees use 10% of their time for further training.

User-Centric and Responsive Design

Our solutions focus on the future user right from the start. The user experience (UX) and user interface (UI) design of the app or portal combine aesthetics and functionality with user-centricity. More on UX Design.

Interface Integration

We develop interfaces to your existing software so that the new app or the new portal is optimally integrated into your system landscape. The new individual software can be integrated with your ERP, CRM, PIM and other peripheral systems via APIs (interfaces). More about Software Development.

Web, Desktop and Mobile

We develop all apps with web technologies that can be used cross-platform. Whether as a mobile app for the smartphone, as a web application for the browser or as a native desktop application. In addition, with modern web technologies, you only have to develop the app once for all platforms (Android, iOS, Windows). This saves you time and money.

Frequently Asked Questions About Web Applications - FAQs

How much does a web or mobile application cost?

The prices are individual and depend on your specific application, the number of functions, the connections to peripheral systems, as well as the approximate time frame and budget. All of our solutions are modular and expandable.

How long does it take to implement an individual software solution?

Similar to pricing, the time to market depends on the scope and size of the visualization to be created. It is therefore advisable to start with a minimal viable product (MVP) with a minimal set of functions in order to test the solution on the market quickly and iteratively. Continue reading

Can a web and mobile application be integrated into my current technical system/system landscape?

In any case. We optimally adapt the software architecture to your circumstances and integrate the solution into your existing systems. Be it from other apps, website and web shop, to ERP, PIM, CRM and more.

Who owns the software, my assets and content?

You, 100%, all the time. The individual software becomes your property after completion. If required, we offer operation and maintenance services.
