Case Study by signundsinn GmbH
Description
EAGO Germany is one of the world's leading manufacturers of high-quality wellness products. The manufacturer's range includes a comprehensive selection of saunas, whirlpools, fittings, showers, and more. Functionality and quality are the top priorities right from the product development stage. The result is a comprehensive range of exclusive bathroom furnishings. EAGO Germany offers a product portfolio specially tailored to the German market.
Solution
Our solution was to carefully replicate the recognizable design in the new shop system and develop custom plugins to ensure a smooth migration of functions. We then carried out thorough speed and SEO optimizations and integrated Google Analytics for comprehensive analytics tracking. Our tasks included Shopware migration, custom plugin development, performance optimization, and ongoing support.
Results
The new Shopware store faithfully reproduces the existing design and ensures seamless transfer of all functions thanks to individually developed plugins. Targeted performance and SEO optimizations have significantly improved loading speed and increased visibility in search engines in the long term. The integration of Google Analytics also enables comprehensive tracking and in-depth analysis of user behavior. The result is a high-performance, future-proof Shopware store that runs smoothly from a technical standpoint and is optimally positioned for further growth.

FAQ
What does signundsinn GmbH do?
My name is Sebastian Theiss and I am Sales & Marketing Manager at signundsinn GmbH. With our team, we see ourselves as partners at eye level in joint projects. We work transparently, economically and with very good codes. We are no friends of escalation management, which is why we communicate a lot and continuously with our customers and partners in all ways to achieve the best result.
What sets signundsinn GmbH apart from the competition?
Clearly, our response times and personal communication. We have a guaranteed response time of 15 minutes. Even if not every problem is solved in 15 minutes, our partners always know that their request will be taken up and processed in a short time. Furthermore, our customers are not ticket numbers, but people with whom we want to achieve the best possible result for their tasks and wishes in joint communication.
What is the project approach of signundsinn GmbH?
Similar to the above point, the current status of a project is always analyzed, what preliminary work, ideas, etc., have already been done. Based on this assessment, a strategy meeting is held in which a common workflow is developed. As soon as the project or support is started, our customers are supported by our professional account management team and can approach the project via real-time chat or any other communication channel with us.
How does signundsinn GmbH calculate scope, time & budget?
At signundsinn there are fixed hourly rates of 110,00€ net. However, the real calculation takes place only after a strategy meeting, in which the needs have been elicited and clearly communicated, so that an estimate can be given as accurately as possible. In the end, the actual time spent is always billed. This system of estimates, combined with our project management software, means that our customers are always aware of all processes and costs and that the final decision-making power always lies with them.
Who is the typical client of signundsinn GmbH?
Medium-sized companies with initial experience in e-commerce
