Elektrohandel Wandelt - Case Study

Elektrohandel Wandelt GmbH is an online shop for high-quality electrical installation supplies with a comprehensive range and customer-orientated service. More than 100,000 customers express their high level of satisfaction  on rating platforms.
As one of the largest specialist electrical shops in Europe with over 80,000 products, Elektro Wandelt is regarded as a leading company on the German and European market. The company stands for favourable prices, competent advice, friendly service and fast delivery.

The company's aim is to offer customers in the B2C and B2B sectors an efficient and best possible shopping experience. The user-friendliness and speed of the company website is a high priority for the company. High-quality website performance is the key to increasing the conversion rate and user-friendliness as well as a better search engine ranking.

The Elektro Wandelt online shop is based on OXID EE. In order to optimise and improve the webshop performance, our OXID eShop agency implemented additional measures:

• Cleaning the website of outdated elements in the code, outdated modules, outdated backups and other „useless“ code left behind by previous developers to prevent hacker attacks and website failures.
• The size of the graphic content has been improved with the Oxid Image Optimiser module for different screen resolutions.
• Static content is cached by Ngnix, which can provide it (directly) very efficiently.
• The use of AJAX when filling the shopping basket makes the shopping experience easier for the user. AJAX allows users to add products to the shopping basket immediately without having to reload the same page several times.
• CSS and JavaScript minimisation to speed up page rendering.
• Time reduction for HTTP requests.
• Installation of the new HTTP/2 protocol, which enables multiple data requests to be sent in parallel and stream prioritisation.
• Development of a  specific module to connect Varnish Cache with Oxid EE.

In order to adapt the e-commerce website to customer needs and add new functionalities, the following measures were developed and implemented in collaboration with the Elektro Wandelt team:

• Optimization of the website design.
• Adjustment of the product card layout (delivery time display, variants, energy label, reviews) on the category page.
• Modification of the product page (anchor navigation, integration of eKomi reviews, OEM articles).
• Implementation of new payment systems (PayPal PLUS, Crefopay).
• Optimization of prepayments, invoices, cancellations, and returns.
• Extension of discount handling functionality.
• Development of a quote capture feature and implementation of the respective customer process.
• Implementation of order tracking for customers.

Our team developed an application for the customer's suppliers based on EspoCRM. This application is aimed at automating business processes and optimizing the delivery process for both suppliers and the company.

The application based on EspoCRM offers:

• Automatic import of CSV files with order data for suppliers.
• Email-driven communication regarding defined data corrections on both the supplier and company sides.
• Configuration of fields for Ajax live search.
• Improved sorting function.
