There are basically 3 Models of IT support.
Break/Fix
In the break/fix scenario, an IT repairman is called when a device or software malfunctions. The technician makes his/her money when things are going wrong in your business processes.
Retainer or Block Hours
This model is very similar to the break/fix model in makeup and results. The difference here is that you have pre-paid someone to be available for your breakdowns rather than panicking to find someone when your technology goes wrong.
Managed IT Services
The Managed IT Services model is superior to the previous two models we have discussed because it is proactive in nature and incentivises the IT support company providing the service to keep your IT systems running optimally at all times. Managed IT Services is a subscription IT support offering based on a set monthly subscription payment. One stable monthly payment gives the client complete, continuous IT management, maintenance, and operational/security monitoring.
