What should I check before hiring an IT support company?
Verify credentials such as vendor certifications and relevant experience, and ask about response times, escalation procedures, and data-handling practices. Get a clear scope of work and a written service agreement that outlines uptime expectations, support hours, and exit terms.
What do typical IT support services cover?
Common offerings include helpdesk support, routine maintenance and patching, network monitoring, data backup and recovery, and endpoint protection. Some firms also provide project work like migrations or security audits, but make sure any project scope is agreed in writing.
