How to choose a managed IT service provider

  1. Ask for a sample service-level agreement and compare response times, support hours and exclusions.
  2. Check how backups are done and tested, and ask when they last restored a client’s data.
  3. Ask which security tools are included and which cost extra (MFA, endpoint protection, email filtering, staff training).
  4. Make sure you, not the firm, own your accounts, domain names and licences.
  5. Ask for two or three references from clients of your size and industry, and call them.
  6. Get the scope, response times and price in writing before you sign, including how you leave and get your data back.

Questions to ask a managed IT service provider

  • Is the price per user, per device or a bundle, and what is not included?
  • What are your response times for urgent, normal and low-priority tickets?
  • Is your help desk in-house or outsourced, and what are its hours?
  • How do you back up our data, how often do you test restores, and where are the copies kept?
  • Which security tools are included, and do you monitor alerts after hours?
  • What happens to our passwords, documentation and data if we leave?
  • Can you give us references from clients of our size and industry?

What does a managed IT service provider do?

Managed IT service providers (MSPs) run a business’s computers, servers, network, Microsoft 365 or Google accounts, backups and help desk for a monthly fee, or provide IT support by the hour.

What should a managed IT agreement include?

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.

Is managed IT priced per user or per device?

Both models are common, and some firms sell tiered bundles. Per-user pricing suits staff with several devices; per-device pricing suits shared computers. Compare quotes on the same number of users, devices and servers.

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.
