Managed IT support
This is the ongoing agreement: a named contact, a route for staff to ask for help, and notes a manager can read after the event. It suits an office that wants the ordinary faults and the ordinary changes handled without starting from nothing each time.
Security, backup and Microsoft 365 can sit inside that agreement or be commissioned on their own. A network replacement or an office move is project work, with its own written scope, even when the same contact remains accountable.
