Unlike hardware, software cannot be used up. This means: even when buying second-hand, you get a product that is like-new. This is because you are not acquiring any physical goods, just user rights – and these can be resold according to a law passed in 2012.
The main case for using used software is the cost involved: you get the same quality as you would from the manufacturer, including the right to update and downgrade, but you pay a great deal less. This helps you to make significant savings in terms of your IT budget and to optimise the use of resources.
Savings of up to over 50% compared with “new” licences are commonplace when using used software.
