## Insureon vs THREE by Berkshire Hathaway Inland Marine Insurance Summary

Insureon describes contractor tools and equipment as inland marine property; THREE lists the line within its Business Owners Policy and routes prospects to an online quote and licensed advisor. [3](https://www.insureon.com/small-business-insurance/contractors-tools-equipment "Tools & Equipment Insurance for Contractors - Get Online Quotes") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [5](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") [4](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway")

## What is Insureon?

Insureon describes a small-business insurance agency and broker route with online quote entry and agent support. Its pages market several coverage types, but do not establish which insurer, policy form, state availability, or eligibility applies to a particular buyer. [1](https://www.insureon.com/about-us/how-insureon-works "How Insureon Works") [2](https://www.insureon.com/small-business-insurance/general-liability "General Liability Insurance - Get Online Quotes")

## What Is Inland Marine Insurance?

If your business moves equipment between sites or ships goods, inland marine can cover those property exposures; installation and other forms address different property categories. Match the quote to what you own, rent or hold for others. [7](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [8](https://www.dms.myflorida.com/content/download/132333/823484/SoF_Policy_CE_17-18_UM00056635MA17A.pdf "Inland Marine Policy: Contractors’ Equipment")

## What Are the Key Differences Between Insureon and THREE by Berkshire Hathaway Inland Marine Insurance?

### Product Structure

Insureon markets a contractor tools-and-equipment line under the inland marine label and offers an online quote request. THREE places inland marine within its combined Business Owners Policy rather than describing it as a separate standalone policy. If you want to consider equipment protection in the context of a broader small-business policy, THREE’s packaging is explicit; with Insureon, ask whether the offered coverage is separate or tied to another policy before comparing totals. [3](https://www.insureon.com/small-business-insurance/contractors-tools-equipment "Tools & Equipment Insurance for Contractors - Get Online Quotes") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### What the Public Descriptions Establish

Insureon gives examples of mobile tools and equipment at jobsites, in transit, or off-site, including theft or damage. THREE’s product page lists Inland Marine as a category in the package but does not establish which losses or items the category covers for a particular buyer. Those descriptions are not interchangeable: ask THREE to point to the quote’s inland marine terms and ask Insureon which scheduled property and locations the proposal covers. [3](https://www.insureon.com/small-business-insurance/contractors-tools-equipment "Tools & Equipment Insurance for Contractors - Get Online Quotes") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Limits and Purchase Route

THREE directs small-business buyers to an online quote and licensed advisors, with limits and deductibles listed in the quote-specific insurance summary; its public page does not give a separate inland marine amount. Insureon’s public overview likewise does not supply the buyer’s limits or deductible. Compare the actual summaries, not the product labels, and check that the scheduled property values fit your equipment. [3](https://www.insureon.com/small-business-insurance/contractors-tools-equipment "Tools & Equipment Insurance for Contractors - Get Online Quotes") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

## What Should You Confirm in Insureon and THREE by Berkshire Hathaway Inland Marine Insurance Quotes?

- Which specific tools, equipment, transit routes, and off-site locations are covered under each proposed form? [3](https://www.insureon.com/small-business-insurance/contractors-tools-equipment "Tools & Equipment Insurance for Contractors - Get Online Quotes") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")
- In THREE’s package summary, what separate inland marine limits and deductibles apply, and is that category included in your particular quote? [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

The quote and issued declarations control the buyer-specific limit and deductible..) |
| How to Apply | The cited Insureon product page provides an online quote request path; that route does not identify the insurer or guarantee that a quote will be offered or bound. [3](https://www.insureon.com/small-business-insurance/contractors-tools-equipment "Tools & Equipment Insurance for Contractors - Get Online Quotes") (Evidence: Company-reported; scope: Insureon’s public marketing page and quote route documents this description.

[4](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product. It does not show whether Inland Marine will be offered for a particular business or whether a customer can bind that line without an issued policy..) |
