IT Documentation Best Practices for MSPs
How to build and maintain IT documentation that actually gets used — templates, processes, and the tools that make it sustainable.
Every MSP knows documentation is important. And yet, most MSPs have documentation that's incomplete, outdated, or scattered across spreadsheets, shared drives, and the brains of senior techs. The problem isn't motivation — it's process and tooling.
What to Document
Per-Client: Network topology diagrams. Server configurations. Application stack. Admin credentials (in an encrypted vault). Contact information. SLA terms. Backup procedures. Disaster recovery plan. Vendor contacts and account numbers.
Per-Asset: Hardware specs. Software inventory. IP addresses. Warranty information. Physical location. Related documentation. Linked tickets.
Organizational: Standard operating procedures (SOPs). Runbooks for common tasks. Onboarding/offboarding checklists. Security incident response procedures. Change management processes.
Knowledge Base: Solutions to common problems. How-to guides for client-specific applications. Troubleshooting decision trees. FAQ articles for the client portal.
The Documentation Decay Problem
Documentation has a half-life. The moment you write it, it starts becoming outdated. Server configs change. Passwords get rotated. Procedures evolve. If you don't have a system for keeping documentation current, it becomes worse than no documentation — because techs will follow outdated procedures and make things worse.
The solution: expiration flags and review cycles. Every document should have a review date. When that date passes, it gets flagged as potentially stale. Assign document owners who are responsible for periodic reviews. Your documentation platform should surface stale documents on a dashboard so nothing falls through the cracks.
Making Documentation Sustainable
The key insight is that documentation should be a byproduct of work, not extra work. When a tech resolves a ticket, the solution should flow directly into the knowledge base. When a new server is deployed, the configuration should be automatically captured by your RMM. When a password is changed, the vault should be updated as part of the change process.
This is why integrated documentation — built into the same platform as your RMM, ticketing, and asset management — dramatically outperforms standalone documentation tools. The data is already there; you just need to organize and enrich it.
