In addition to strong sales through established brands like 1&1, GMX, WEB.DE, IONOS, STRATO and Versatel, United Internet is also known for outstanding operational excellence. Individuals and business customers at United Internet receive landline and mobile internet access products as well as various cloud applications – since the end of 2023, also in their own, modern 5G network. The use of these services is managed through subscription contracts with fixed monthly amounts and variable, consumption-dependent additional fees.


The United Internet Group is represented at around 40 domestic and international locations, generating an annual turnover of approximately 6 billion EUR.

As a leading internet provider with a broad brand and service portfolio ranging from mobile contracts, broadband internet, web hosting, cloud, and e-business services to individual telecommunication solutions, United Internet has an extraordinarily large and growing customer volume. With over 28 million paid customer contracts from both individuals and businesses, the volume of direct debits and transactions that the Treasury systems must handle efficiently is substantial.


However, this is precisely where a challenge presented itself. The existing systems were significantly strained due to the mass of transactions and data, risking system crashes during routine operations such as using search functions. Additionally, the Treasury system landscape was characterized by a multitude of different, non-harmonized ERP systems at various locations, resulting in gaps in system communication and inefficient processes.
