This is a great way in which to obtain brand new hardware when it is required, which is something that your staff will appreciate too.
By constantly keeping up to date with IT, you ensure your machines and infrastructure keeps up with your business requirements and the requirements that ever more powerful solutions may incur. Leasing your equipment also reduces your environmental impact, both by using the newest more environmentally friendly machines, but also by reducing the disposal of old IT equipment.
Further benefits include valid warranty periods for your hardware, ensuring any sort of failure is fixed or replaced at no extra cost, often in the same or next business day.
