The goal
Flexible content management system with impressive performance in WordPress
oekostrom AG is an established energy supply company specializing in the production, trading, and distribution of energy from 100% renewable sources in Austria.
As part of a brand relaunch, both the design and key functionalities and digital processes of the website and customer portal were completely redesigned by LWND. The goal was to ensure that users could reach their objectives in just a few clicks, while adhering to current standards for user experience and conversion optimization.
From the outset, the client’s preferred CMS for both the website and customer portal was WordPress, largely due to its user-friendliness for editors. As an experienced WordPress agency, we took on the technical realization of both projects.
In addition to WordPress-specific development tasks such as theme and plugin programming, a key focus was on the robust integration of numerous interfaces to ensure that user data is reliably transferred during the switching and ordering processes.
Resonanz is more than just a partner for us — they are truly part of the team. Their reliability and expertise in executing this extensive website project once again demonstrated why we have been working together successfully for many years. Their professionalism and commitment played a key role in bringing our strategy, design, and user journey to life. We look forward to many more successful projects with the Resonanz team by our side.
The path to success
Unique web solutions for individual wishes
Custom content management system
From the outset, it was clear that the website would be a key component of oekostrom AG’s online marketing mix. This brought with it the requirement that the online editorial team should be able to easily adapt and expand the website content. As part of the daily workflow, creating new pages and landing pages needed to be as straightforward as possible.
On the basis of a modern page builder, we developed numerous custom content elements (e.g. sliders, call-to-action boxes, image galleries, and more) that can be seamlessly integrated into the website with minimal effort. A comprehensive manual enhances the user experience and ensures that the online editorial team can work largely independently of agency support.
Fast loading times and accessibility
A convincing user experience requires many components: from the concept and design to programming for high website speed, multiple disciplines are involved. Implementing the site as an accessible website plays a major role here, not only because it can improve search engine rankings, but also because it significantly expands reach by including people with disabilities.
To ensure fast loading times, even during interactions within the customer portal, we used a combination of WordPress for content management and the JavaScript framework Svelte for the frontend. This allows oekostrom AG’s editorial team to benefit from WordPress’s familiar advantages, while customers enjoy the modern user experience of a reactive web application.
Seamless processes through interfaces
Both the order and switching process on the website, as well as the customer portal, needed to integrate seamlessly with existing software for internal contract and customer management. At the same time, all interactions on the digital platforms had to offer an optimal user experience, and content management via WordPress had to be fully functional without any limitations.
Connecting to numerous external interfaces (APIs) was therefore a central part of the project. From calculating the individual installment amount, to contract completion for energy consumers and producers, to the full self-service customer portal: our robust and error-monitored API communication ensures smooth process flows in all areas.
Quick response times and communication on equal terms
Collaboration between many players requires open and clear communication. To implement the project, we relied on proven project management tools that allowed all involved experts to communicate easily and stay organized.
Weekly meetings with our partner agency and the end client contributed to a smooth and high-quality development process. We believe the results speak for themselves!
