The IT documentation every small business should keep
Good IT documentation is not paperwork for its own sake. It lets a business understand what it owns, who can access it, which suppliers matter, how systems connect and what to do when something breaks. Without it, ordinary staff changes or urgent incidents become slower and riskier than they need to be.

The short answer
Maintain a business-owned record of users, devices, systems, cloud accounts, domains, licences, suppliers, network details, backups, recovery contacts and key support procedures. Keep sensitive credentials out of ordinary documents and review the record whenever the environment changes.
What useful IT documentation looks like
Useful documentation is current, accessible to authorised people and written for the decisions the business will need to make. It should make a handover, recovery or provider change easier without exposing passwords or sensitive information.
The essential records
Systems and assets
Users, devices, servers, network equipment, applications, locations and ownership.
Accounts and suppliers
Business-owned domains, cloud tenants, licences, vendors, renewal details and escalation contacts.
Recovery and support
Backup scope, recovery priorities, support process, emergency contacts and key change history.
Who this is for
- Businesses dependent on one person who knows the setup.
- Teams changing IT providers or bringing on new staff.
- Owners preparing for a security, continuity or insurance review.
How to build it
- Start with a system inventory. List what the business uses before trying to document every technical detail.
- Confirm business ownership. Check that accounts, contacts and renewals are controlled by the business rather than an individual.
- Review after change. Assign an owner and update the records whenever systems, staff or suppliers change.

IT documentation questions
Should passwords go in the documentation?
Document where authorised credentials are managed and who controls them, but use an approved password-management process rather than ordinary files or spreadsheets.
Who should own the documentation?
The business should own it, with authorised staff and providers granted access appropriate to their role.
