IT Documentation for MSPs: Tools, Templates, and Best Practices

Bad documentation costs real money. A tech spends 15 minutes hunting for a password or network diagram that should be in the system. Multiply that across 20 tickets a day, 5 technicians, and 250 working days - you're looking at thousands of hours per year burned on finding things instead of fixing things. Good IT documentation isn't a nice-to-have. It's the difference between an MSP that scales and one that drowns in tribal knowledge.

What IT Documentation Covers

Before comparing tools, it helps to define what "it documentation" means for an MSP. It's not just writing things down. It's building a structured, searchable system that covers:

Client documentation: Network diagrams, IP schemas, hardware inventories, software licenses, login credentials, escalation contacts, SLA details, and site-specific procedures. Every client should have a standardized set of docs that any technician can pick up cold.

Standard operating procedures (SOPs): Step-by-step instructions for recurring tasks - onboarding a new client, setting up a firewall, deploying a new workstation, handling a security incident. SOPs reduce errors and make training faster.

Runbooks: Detailed troubleshooting guides for known issues. "Client X's VPN drops every Thursday" gets a runbook entry with the root cause and fix, so the next tech doesn't start from scratch.

IT infrastructure documentation: Network topology, server configurations, backup schedules, DNS records, certificate expiration dates, and vendor contact info. This is the documentation that saves you during an outage at 2 AM.

Password and credential management: Secure storage for admin passwords, API keys, service accounts, and MFA recovery codes. This overlaps with documentation but often lives in a dedicated vault (IT Glue, Hudu, and Passportal all include password management).

IT Documentation Best Practices That Actually Stick

Most "best practices" articles list obvious advice - "keep it updated," "make it accessible." Here's what separates MSPs with documentation that works from those with a half-empty wiki nobody trusts.

Build Documentation Into the Ticket Workflow

The number one reason documentation goes stale: it lives outside the daily workflow. If a tech has to leave the ticketing system, open a separate tool, find the right article, and update it manually, it won't happen consistently.

The fix: make documentation a required step in ticket resolution. Your PSA or ticketing tool should link directly to documentation entries. When a tech resolves a ticket using a procedure that doesn't exist in docs yet, creating that doc should be part of closing the ticket. Some MSPs add a "Documentation Updated" checkbox to their ticket templates.

Standardize With Templates

Every client environment should be documented using the same template structure. When a tech opens any client's documentation, the layout should be identical - network overview first, then credentials, then SOPs, then escalation procedures.

This matters more than it sounds. A tech working across 30 clients shouldn't have to learn 30 different documentation layouts. Consistency reduces cognitive load and speeds up resolution times.

Core templates every MSP needs:

Client onboarding template: Contact info, network diagram placeholder, IP schema, domain details, critical applications, backup configuration, vendor contacts, SLA terms.

Network documentation template: WAN/LAN topology, VLAN assignments, firewall rules, DHCP scopes, DNS configuration, VPN settings, wireless SSIDs and security.

Server documentation template: Hostname, OS version, role/services, IP address, backup schedule, maintenance window, admin credentials (linked to vault), monitoring thresholds.

Workstation standard build template: OS image, required software, group policy assignments, security baseline, user setup procedure.

Use the 15-Minute Rule

If documentation hasn't been reviewed in 90 days, flag it for review. If a tech spends more than 15 minutes looking for information that should be documented, that's a documentation failure - create or update the entry immediately after resolving the issue.

Some MSPs run monthly "documentation sprints" where each tech spends 2 hours updating and improving docs for their assigned clients. The time investment pays back quickly in faster ticket resolution and smoother client onboarding.

Separate Credentials From Documentation

Passwords and API keys should live in an encrypted vault with access controls, audit logging, and automatic rotation where possible. Storing credentials in the same Wiki or document as your network diagrams creates security risk. Most modern MSP documentation tools include built-in password management, but make sure it uses proper encryption (AES-256 at minimum) and supports role-based access.

MSP Documentation Software Compared

The MSP documentation software market has a clear leader (IT Glue) and several strong alternatives. Here's how they compare on what matters.

IT Glue

IT Glue is the most widely used documentation platform among MSPs. It's cloud-hosted, integrates with most RMM and PSA tools, and provides a structured framework for documenting clients, networks, passwords, and SOPs.

Pricing: $29/user/month with a 5-user minimum ($145/month floor). Enterprise plans run higher. IT Glue was acquired by Kaseya in 2019, and pricing has increased since the acquisition - a pattern Kaseya repeats across its portfolio.

Strengths: Deep PSA/RMM integrations (especially with Kaseya products), structured documentation templates, password management built in, asset tracking, SOC 2 compliance.

Weaknesses: Customer support has declined post-Kaseya acquisition (a frequent complaint on r/msp). Pricing is steep for small MSPs. You're locked into Kaseya's ecosystem, which comes with the same vendor lock-in concerns that affect their RMM and PSA products.

Hudu

Hudu has grown fast as the primary IT Glue alternative. It offers a similar feature set - client documentation, password management, asset tracking, SOPs - at a lower price point.

Pricing: Starts at $23/user/month (cloud) or $35/user/month (self-hosted). The self-hosted option is Hudu's differentiator - you own the data and infrastructure.

Strengths: Self-hosting option, lower price than IT Glue, fast customer support, clean interface, strong API, active development pace. Many MSPs switching from IT Glue cite better support and lower cost as primary reasons.

Weaknesses: Fewer native integrations than IT Glue (though the API helps). Self-hosting requires server management. Newer product, so some features are still catching up.

ITFlow

ITFlow is the open-source option. It's free, self-hosted, and covers client documentation, passwords, network info, and basic ticketing.

Pricing: Free (open source). You pay for hosting and your time managing it.

Strengths: Zero licensing cost, full data ownership, active open-source community, includes basic PSA features (ticketing, invoicing). For MSPs comfortable with self-hosting, ITFlow eliminates documentation software as a line item entirely.

Weaknesses: Fewer features than IT Glue or Hudu. No dedicated support team - you rely on community forums and documentation. Setup requires Linux administration knowledge. Best suited for smaller MSPs willing to trade features for cost savings and data control.

Other Options

N-able Passportal: Cloud-based, strong password management, integrates with N-able's RMM suite. Good if you're already in the N-able ecosystem. $18/user/month starting.

Confluence: Not MSP-specific, but some MSPs use it for internal documentation. Flexible, cheap ($5.75/user/month), but lacks MSP-specific features like password vaults and client-centric structure.

NinjaOne Documentation: NinjaOne added documentation features to its RMM platform. Basic compared to dedicated tools, but it keeps everything in one interface. Good enough for MSPs with simple documentation needs.

Building Your Documentation System

If you're starting from zero or rebuilding a neglected documentation system, here's a practical sequence:

Week 1-2: Pick your tool and set up templates. Choose a platform based on your budget and hosting preference. Create standardized templates for client overviews, network documentation, and SOPs. Don't customize heavily yet - start with the basics.

Week 3-4: Document your top 5 clients. Start with your highest-revenue or most-complex clients. Populate network diagrams, credential vaults, and critical SOPs. This gives you a working model to refine before scaling.

Month 2: Roll out to all clients. Assign each technician a set of clients to document. Set a deadline. Run a weekly check on completeness. Some MSPs gamify this - whoever documents the most clients in a month gets a reward.

Month 3+: Integrate with your workflow. Connect documentation to your PSA so techs can access docs from tickets. Add the "Documentation Updated" step to ticket resolution. Schedule quarterly reviews.

The goal isn't perfect documentation on day one. It's building the habit so documentation improves continuously. A documentation system your techs use at 70% completeness is better than a perfect system nobody opens.

If your PSA is part of the bottleneck, we compared the best PSA software for MSPs - several options integrate directly with documentation tools.

The Vendor Lock-In Problem in Documentation

Documentation is one of the stickiest tools in your stack. Once you've documented 50 clients with thousands of entries, passwords, and network diagrams, switching platforms is painful. Vendors know this.

IT Glue's Kaseya acquisition is the clearest example. Post-acquisition price increases pushed some MSPs to explore alternatives, but the migration effort kept many locked in. Your documentation data - passwords, procedures, client information - becomes leverage for the vendor.

This is why the self-hosted and open-source options (Hudu self-hosted, ITFlow) are worth considering even if they require more setup work. You control the data. You control the infrastructure. If you decide to switch tools in two years, your data is already on your servers.

For MSPs already feeling squeezed by vendor costs across their stack, documentation is a good place to start reducing dependency. Tools like ITFlow prove that core documentation functionality doesn't require $29/user/month. The open-source MSP movement is building alternatives across every category - RMM, PSA, documentation, and more.

FAQ

What is IT documentation?

IT documentation is the organized record of an organization's technology infrastructure, processes, and procedures. For MSPs, this includes client network diagrams, server configurations, credentials, standard operating procedures, runbooks, and vendor information. Good documentation lets any technician resolve issues without relying on tribal knowledge.

What's the best IT documentation software for MSPs?

IT Glue is the most widely used, but it's not the only option. Hudu offers similar features at lower cost with a self-hosting option. ITFlow is free and open source. The best choice depends on your budget, hosting preference, and how many integrations you need. For most MSPs under 10 technicians, Hudu or ITFlow provides enough functionality without IT Glue's price tag.

How do I start documenting IT infrastructure?

Start with templates. Create a standard client documentation template covering network topology, IP schemas, credentials, backup configurations, and escalation contacts. Document your top 5 clients first using that template, then scale to all clients. Assign documentation responsibilities to specific technicians and review completeness monthly.

What should an IT documentation template include?

A complete client documentation template covers: company overview and contacts, network diagram, IP schema and VLAN assignments, server inventory with roles and configurations, workstation standards, backup schedule and verification, firewall rules, VPN configuration, DNS records, credential vault links, SLA terms, and escalation procedures.

Is IT Glue worth the price?

At $29/user/month with a 5-user minimum, IT Glue costs at least $1,740/year for a small team. It's feature-rich and well-integrated with Kaseya's ecosystem, but post-acquisition support quality has declined. MSPs paying for IT Glue should evaluate whether Hudu ($23/user/month with self-host option) or ITFlow (free, open source) could meet their needs at lower cost.

How often should IT documentation be updated?

Review critical documentation (network diagrams, credentials, SOPs) at least quarterly. Update documentation immediately when infrastructure changes - new servers, network changes, vendor switches. Flag any document untouched for 90+ days for review. Build documentation updates into your ticket resolution workflow so updates happen naturally rather than in bulk.
