Most IT Services providers will provide Break Fix services and many will also provide some form of Proactive services too.
It’s the a proactive arrangement that’s most important if your business relies on Information Technology to continue operation. It’s also essential if you wish to make better use of IT in the organisation.
If a provider offers break fix services in any form then avoid them as their business model is one where they are paid if you break down. Naturally this leaves no incentive for them to make your systems reliable.
