s2-Software has received TÜV Saarland certification for its “Secure License Transfer” process, which is used in the trade of used software licenses. The process certification confirms that license transfers are carried out in a structured, transparent and legally compliant manner, with a strong focus on legal certainty, transparency and customer orientation.
As part of the TÜV audit, our Confirmed License Transfer Process was comprehensively assessed. The aim of the certification was to verify that the license transfer, as a service process, is properly managed and meets all relevant legal and organizational requirements.
Key results of the process certification:
Documented and controlled processes The entire license transfer process is fully documented, versioned and subject to clearly defined authorization and control mechanisms. Operational implementation is ensured by qualified personnel with the necessary expertise.
Legal security and compliance The process meets all legal requirements for software license transfers. All relevant criteria, standards and required evidence are clearly defined, kept up to date and transparently documented.
Quality assurance and risk management An established quality assurance system ensures long-term compliance with the defined standards. In addition, a structured process for identifying, assessing and controlling risks is in place to minimize potential threats.
Customer orientation and transparent communication Customer-related information, texts and documents are prepared in a clear and understandable manner. Complaint handling and feedback processes are clearly defined, and customer satisfaction is regularly monitored and evaluated.
The TÜV Saarland certification confirms that the “Secure License Transfer” implemented by s2-Software meets the highest standards in terms of organization, process management and regulatory compliance. Customers benefit from a reliable, transparent and verified process for trading used software licenses.
s2-Software will continue to monitor and further develop this process to ensure the highest standards in license transfers in the future.
What is the difference between used software and new licences – the quality? No, unlike used cars, programs like Microsoft Office show no signs of usage. Instead, the used software offers the same range of functions as on the first day. However, there is a significant difference in price: if you implement used software from s2-Software in your company, you can save up to 72% compared to purchasing the respective new licences! In other words, with our help, you can significantly reduce your company's IT costs.
You will not have to compromise on functionality or legal certainty: we ensure that the transfer of the used software licences is carried out in accordance with the applicable law and the current manufacturers' specifications. That is why, in addition to the download and the licences, you will receive comprehensive documentation of the legally compliant transfer from us. With these documents, you can prove to the manufacturer that your software was purchased correctly. This gives you full sovereignty and you are no longer dependent on s2-Software – although we will, of course, happily continue to support you if you have any questions.
Buy used softwareUpgrading software in a company involves considerable investment. We give you the opportunity to release some of this capital if you are no longer in need of old licences after the upgrade.
For example, there are currently many companies migrating to the Cloud with programmes like Office 365. This makes on-premise solutions superfluous, but the company still owns them. We help you to avoid such redundancies while also increasing your budget. We are always interested in purchasing used software licences that are no longer needed and would be pleased to prepare a personalised offer for you.
The price we can offer in individual cases depends mainly on the versions offered and the number of licences. In general, however, it is always worthwhile selling software that is no longer needed – even if only a few licences have been freed up through rationalisation.
