Why is IT Support Important in a Business?

Businesses have uptime and downtime measures, and depending on the nature of your product or service, downtime might result in significant losses. This is especially true in businesses where access to IT resources such as cloud computingremote access, and VoIP telephony needs to be consistent. If any downtime happens in those hours of operation, critical errors could be made which ultimately affect ongoing projects, and in the end, the business’s bottom line.

Small business IT support is integral to HSC Systems’ business model because we believe that SMMEs are the engine that drives South Africa’s economy. As such, affordable IT support which is geared towards resolving issues in the most efficient and rapid ways possible is a top priority.
