At minimum: help desk support for your staff, monitoring and patching of computers and servers, backups that are tested, security tools such as endpoint protection and multi-factor authentication, and a named contact. The agreement should state response times, support hours and what counts as out of scope.

How long are managed IT contracts?
Often one to three years, sometimes month to month. Check the notice period, any early-termination fee and how the firm hands over passwords, documentation and data when the contract ends.
