What happens if my IT person quits tomorrow?

When your IT person walks out the door—whether by choice, burnout, or sudden illness, your business doesn’t just lose a single employee. You lose access to passwords, systems knowledge, vendor contacts, and the person who knows what’s duct-taped together behind the scenes. For companies in growth mode, this isn’t just inconvenient, it’s a risk to operations, security, and momentum.

According to a 2024 study by Gartner, 45% of mid-sized companies reported a “critical knowledge gap” when a sole internal IT employee left the organization. That gap can quickly turn into downtime, breaches, or compliance issues.

For SMBs. especially those with no formal IT team or backup plan, the departure of a key IT staff member can halt progress. Projects get delayed. End users lose support. And worst of all, no one knows who has access to what.

This article will explore the specific risks of losing your IT person without a plan, outline proactive strategies to protect your business, and help you evaluate whether your current setup is built for groth, or held together by one employee.

Common Risks When Your IT Person Leaves

When an internal IT employee quits without a transition plan, small and midsize businesses face serious disruptions, many of which go unnoticed until it’s too late.

1. Loss of Institutional Knowledge

Most SMBs don’t have centralized documentation for IT systems, configurations, passwords, or vendor relationships. That information often lives inside the head of the IT person, meaning when they leave, so does critical context.

Only 32% of organizations have formal IT documentation processes in place (Ponemon Institute, 2023).

2. Access and Security Risks

Without clear access controls, offboarding a departing IT employee becomes a scramble. If the person had admin rights or control of your firewall and backups, your exposure multiplies.

3. Compliance Gaps

A lack of IT continuity can trigger security and data compliance violations. If system logs can’t be maintained, backups fail, or alerts go unresolved, the risk extends beyond IT; it becomes a legal liability.

4. Operational Downtime

Without someone on call who understands your environment, even small issues take longer to resolve. Your help desk slows down. Onboarding new staff takes longer. Infrastructure projects stall.

These challenges aren’t theoretical. They happen every week in businesses that rely on a single IT generalist without backup, documentation, or outside support.

How to Protect Your Business Before It Happens

You don’t need to wait for a resignation email to take action. Here are five strategic, practical ways to prepare your organization before you lose your IT person.

1. Build an IT Continuity Plan

What it is: A documented process that outlines how your IT systems will remain operational if your primary staff leaves.

Why it matters: It ensures your business can keep running without interruption, even during a staffing gap.

How to implement:

• Document key systems, vendors, logins, and configurations
• Identify backup personnel or an external MSP
• Review annually as your tech stack evolves

Business impact: Reduces the risk of operational downtime and ensures continuity across teams.

2. Centralize Documentation

What it is: Creating a secure, shared knowledge base with up-to-date information on systems, processes, and contacts.

Why it matters: Documentation is what turns individual knowledge into company knowledge. It allows new team members (or an MSP) to get up to speed quickly.

How to implement:

• Use secure platforms like ITGlue, Confluence, or SharePoint
• Assign documentation ownership
• Update every time a system changes

Business impact: Lowers onboarding time and prevents critical knowledge loss.

3. Standardize Access Controls and Offboarding

What it is: A checklist-driven process for removing access, reassigning credentials, and auditing admin rights.

Why it matters: Reduces insider threats and ensures compliance with data security frameworks.

How to implement:

• Implement role-based access control (RBAC)
• Use MFA and centralized identity management
• Automate offboarding steps for IT personnel

Business impact: Enhances cybersecurity posture and protects sensitive data when roles change.

4. Bring in a Managed IT Services Partner

What it is: Partnering with an MSP to provide supplemental or full-service IT support, documentation, security, and planning.

Why it matters: A good MSP doesn’t just react—they build resiliency into your infrastructure. If someone quits, nothing breaks.

How to implement:

• Evaluate providers with industry-specific experience
• Ask about response time, documentation practices, and embedded support
• Choose a partner who can scale as you grow

Business impact: Gives you 24/7 coverage, built-in compliance support, and removes dependency on a single person.

5. Audit Your Current IT Setup

What it is: A regular review of your tech stack, systems, and staffing to identify points of failure.

Why it matters: Most businesses don’t know how fragile their setup is until it’s tested.

How to implement:

• Conduct a quarterly IT risk assessment
• Identify key-person dependencies
• Flag undocumented systems or tools

Business impact: Empowers leadership to make informed decisions before a problem occurs.
