Used Software Is So Much More Than Just a Licence Key: PREO Will Assist You in Your Quest for Secure Licence Transfers.

If you only buy licence keys for used software, you only buy the equivalent of a car key – you can use it to start the engine, but it does not mean that you own the car.

When buying and reselling used software, we go beyond the documentation obligations required in legal practice (Ruling of CJEU in 2012, Az.: C-128/11 and ruling of German Federal Court of Justice (BGH) in 2013, Az.: I ZR 129/08 und 2014, Az.: I ZR 8/13).

In addition to the licence keys, PREO will provide you with everything that makes your company the rightful owner of the software licences. By disclosing the licence history, we exceed the legal requirements. We provide our customers with information about the first owner and the previous owners, including the contract numbers and deletion confirmations.

Our Commitment to Maximum Transparency Has Three Advantages:

  1. Audit readiness: If any questions arise, you will be in a good position to defend yourself – as the documents we check and hand over to you will confirm that our purchasing processes are compliant.
  2. Optimal control and availability: If internal or external auditors want to check the legally compliant purchase receipts, you can present them immediately without having to request them, which can be time-consuming.
  3. Hassle-free resale: If you later decide to resell some or all used licences, it will be straightforward because you will have all the paperwork ready.

PREO Is a Reliable Supplier of Used Software

Today, PREO is one of the few suppliers of pre-owned software, which offers volume licences tailored to the customer's needs combined with the necessary legal certainty and full transparency.

To meet all the requirements and standards of your internal controllers and external auditors, we will provide you with the following:

  1. On request, the licence agreement with the vendor.
  2. The complete chain of rights, including all previous owners.
  3. The documented update history of the purchased software.
  4. Confirmation of the complete deletion of all previous owners.

Proof of the Quality of Our Processes: Insurance Cover Against Financial Losses of Our Customers

Insurance companies will only cover businesses against third-party liability if they are satisfied that everything is being done in that business to prevent an insured event from occurring.


Sell Unused Software Assets

We are also the ideal project partner for the sale of used software licences. The major advantage we can offer you:

  • our experience and the well-established procedures to complete the sales process in a manner that is professional and audit-ready.

While the sale will not put any organisational burden on your IT department, you will improve your cost efficiency, money will flow back to your budget, and you will have cash to spend on new investments.

Gartner's Recommendation: Businesses Should Resell Used Software Licences Instead of Throwing Them Away

At a certain point, IT purchasing managers will find it difficult to continue reducing the high total cost of software licences through better software asset management (SAM).

As early as 2017, Gartner recommended that European companies should reduce their overall software costs by up to 50 percent through various best practices. Surprisingly, businesses largely overlook or fail to take advantage of these opportunities, even where their stated objective is to improve their IT cost-efficiency.  

These best practices explicitly include the sale of used software licences.

European licensees should investigate reselling licences which are no longer used, on the used software market.
