Unexpected issues that occur on systems can have costly labor rates on top of the cost of lost productivity or missed deadlines.  And since you never know when you are going to have issues or how often, it makes it nearly impossible to budget for.

Standard support includes the services of Basic Support and is best for companies that need assistance with hardware or software issues that are above updates and viruses, but want to avoid labor charges regardless of the number of issues that may occur.  This is also a good choice for companies that do not need the additional services that are typical with a full helpdesk.
