Different levels of guarantee
A relevant extra option is 'next business day'. As the name suggests, this means that the company must come and repair the hardware, one day after you report the damage. As an example of a guarantee: for a high-end laptop the standard is often 'next business day accidental care for 3 years'.
Then there is 'mission critical on-site', where the supplier is on site within an agreed period. This can be 2, 4 or 8 hours. The supplier is then on site with the replacement parts if necessary. A laptop, for example, can be easily replaced, but a server has a great impact on the employees. A handy addition, therefore.
