Small Business IT Support: What Should Be Documented?

Useful IT support documentation helps an authorised person find the right system, owner and recovery path when a business service fails. Keep a concise record of domain, hosting, email and website responsibilities, and update it when suppliers or staff change.

The aim is to reduce guesswork during an outage. Record where information is held and who can approve changes; keep passwords and recovery codes in a suitable password manager with controlled access.

Start IT support documentation with account ownership

Start with a map of who owns the domain, hosting, Microsoft 365 or Google Workspace tenant, DNS provider, website administrator accounts and other critical services. Record supplier contacts, renewal responsibility and recovery methods. This prevents a common support problem where nobody knows which account actually controls a service.

Include DNS and email in IT support documentation

Document nameservers and important DNS records, including MX and email-authentication records. For email, record the platform, administrator account ownership, licence arrangement and any shared mailboxes or forwarding rules. Sensitive credentials should remain in an appropriate password manager rather than an ordinary shared document.

Write down recovery information

Good documentation should explain where backups are stored, how often they run, who can restore them and what to do if the primary administrator is unavailable. Include key website integrations and third-party services so a future technician can understand dependencies without discovering them during an outage.

Keep IT support documentation current

Assign responsibility for reviewing the document after supplier changes, migrations and staff departures. Add a last-reviewed date so an engineer can judge whether information is current. The goal is not a huge technical manual; it is a concise map that lets an authorised person find the right system, owner and recovery path quickly when something fails.

Practical takeaway

Test your IT support documentation by asking whether an authorised colleague could identify the provider, contact the owner and locate the recovery instructions without relying on one employee. Resolve missing ownership details before an outage makes them urgent.
