What Happens When Your Small Business Is Underinsured?

For small and midsize business (SMB) owners, there’s an important distinction between having insurance and having enough insurance.

Once a policy is purchased or renewed, it’s easy to check the box and move on to the estimated 30-80 operational, financial, and people-related tasks competing for business owners’ attention each day. But that “check the box” moment can be misleading.

Coverage limits, exclusions, sub-limits, and inflation adjustments are often overlooked, and those details largely determine whether your business can recover from a loss.

Underinsurance isn’t obvious, which is why we’re breaking down the most common reasons SMBs end up underinsured, the red flags to watch for, and what to do next.

What Causes Underinsurance for Small and Midsize Businesses?

1. Your business has grown, but your policy hasn’t

As your business grows, your risk profile changes. Common growth triggers that require coverage updates include:

• Hiring additional employees
• Purchasing new tools, equipment, or vehicles
• Expanding to a new location
• Increasing revenue or payroll

Your policy limits should change as your business grows. This also applies to property insurance because replacement costs rise over time, often faster than owners expect.

Next step: Work with your broker to review asset values and exposures at least annually or after major changes.

2. You assume your policy “has you covered” without entirely understanding it

Insurance policies are dense, technical documents, and many SMB owners understandably rely on assumptions rather than a thorough understanding. This often leads to surprises around:

• Exclusions
• Sub-limits
• Waiting periods
• Coverage triggers

If you don’t know what scenarios are excluded or capped, you may be underinsured even with seemingly high limits.

Next step: Ask your broker to explain, in plain language, what is covered, what is limited, and where claims are most likely to fall short.

3. Cost becomes the primary decision driver

Running a lean business matters, but insurance is not the place to optimize for price. As our co-founder puts it, “Cheap is something poorly made or built to fail.”  And that tradeoff only becomes visible after a loss.

Next step: Prioritize good value and the right coverage over the lowest price. 

4. New and emerging risks aren’t accounted for

Owners of small businesses don’t always account for emerging risks, such as: 

• Cybersecurity threats
• Remote and hybrid work exposures
• Supply chain breakdowns
• Climate-related events

For example, SMBs are targeted nearly four times more often than large organizations in cyber incidents, according to Verizon’s 2025 Data Breach Investigations Report (see more). Yet cyber coverage is not typically included in standard business policies.

Next step: Ask your broker which risks are excluded by default, and which require standalone coverage.

5. “So far, so good” thinking

You know when doctors jokingly say they never want to see you again, suggesting that you’ll stay in good health? Similarly, we hope you’ll never have to call us to file a claim due to a catastrophic event. 

But, just as good health today doesn’t guarantee good health tomorrow, past luck doesn’t protect against future losses. Underinsurance often persists because business owners maintain “so far, so good” thinking.

Next step: Ensure your coverage accounts for all scenarios, not just ideal scenarios.

How Do You Know If Your Business Is Underinsured?

The best thing you can do is ask a trusted broker to assess your current policies. It’s also wise to ask for an assessment in response to emerging risks, like new cyber threats, climate-related events, etc. 

Other red flags that may suggest your business is underinsured include:

• You haven’t reviewed policy limits in the past 12+ months.
• Your revenue, payroll, staff size, location, or equipment has changed.
• Your property is insured at its purchase price, not the current value/replacement cost.
• Your business interruption coverage assumes a faster recovery than is realistic today.
• You don’t know your sub-limits. A sub-limit is the maximum an insurer will pay for a specific type of loss, even if your overall policy limit is higher.
• You rely on your partners’ or vendors’ Certificates of Insurance (COIs) to understand coverage. COIs show proof of insurance, not the details, like exclusions, sub-limits, or conditions.
• You couldn’t comfortably pay all deductibles if a loss occurred tomorrow.

If you caught yourself nodding ‘yes’ as you read through this list, you are not alone. These five considerations show up time and again among the SMB and construction SMB business owners we serve.

What Are the Consequences of Underinsurance?

When your business is underinsured, you may face:

• Insurance payouts are far lower than expected
• Extended downtime
• Cash-flow strain
• Broken trust and reputational damage with customers, vendors, lenders, etc.
• And more

What Should You Do Next?

The good news is that you can change your approach to insurance starting now. Here’s what to do next:

• Ask a trusted broker to assess your current policies.
• Request an assessment that considers emerging risks like cyber, climate, supply chain, etc.
• Look for high-value, right-fit coverage for your business today (not your business yesterday).
