E-commerce is
our expertise
We take a holistic approach in e-commerce, combining strategy, data, and market insight. We create solutions that have an impact far beyond the click and help our clients and partners succeed in the long term.
We are deeply rooted in the digital retail sector, and as solute GmbH, we successfully entered the e-commerce market in 2004 with our well-known price comparison site, billiger.de. Over the years, this has evolved into a powerful network – billiger.de solutions – that delivers measurable results for online shops.
Since 2025, the team from Checkout Charlie has been strengthening our group with innovative cashback solutions that engage shoppers and build long-term loyalty. This is how we combine performance with smart incentives – to encourage returning customers, boost sales, and deliver real value.
Our business units operate independently but benefit from the collective expertise of the entire solute Group.
Since 2023, we are part of Ad pepper Gruppe ›
