Onsite service
We're normally available for calls between 10am-10pm, 7 days per week however, in a real crisis we'll work on until all is resolved. Modern day virus removals frequently take a long time as the machines are running very slow at the start. Backing up and sanitising a users files can take a while and so we sometimes take these machines to our workshop for overnight service.
If you're a large company you can afford to have one or more people onsite to take care of all things technical. For the smaller company or sole trader though this just isn't viable and yet, if things go wrong, your enterprise can grind to a halt.
