In order to take a sales executives’ laptop and turn it into money, a process needs to be followed.
The item must be collected and a record made, the item is then cleaned, the data is wiped and the unit is then tested.
Once working a market value can be established and the PC can be sold, at that point there will be cash generated!
Part of which comes back to you and the balance of course will go to a company such as SITR that carries out the process.
Contact SITR to understand what value your old IT has and make sure that all your data is properly destroyed!
