## Aon vs Harper Surety Bonds Summary

Aon: construction surety bonds and describes them as financial security intended to guarantee contractor performance and payment to specified subcontractors, laborers and material suppliers. Actual bond obligations depend on the bond form and its terms. Harper: surety bonds rather than underwriting them: it says a bond is a promise, backed by a separate bond company, that the applicant will do what a license or contract requires, and Harper places that promise, it does not stand behind it. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. [1](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [2](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## What Is Harper Insurance?

Harper suits hard-to-place businesses such as contractors, care providers, manufacturers and transportation firms; standard small businesses seeking direct quotes should compare online carriers. Its workers’ compensation service helps classify payroll for audits.

## What Are Surety Bonds?

A surety bond guarantees that your business meets a specific obligation to a customer, contracting party or government agency. If a contract, license or permit requires one, get its exact form and amount; a bond is not insurance for your own losses. [7](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [8](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds") [9](https://www.law.cornell.edu/uscode/text/40/3131 "40 U.S. Code § 3131 — Bonds of contractors of public buildings or works") [10](https://www.chubb.com/us-en/surety.html "Surety Bonds") [11](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

## What Are the Key Differences Between Aon and Harper Surety Bonds?

### Bond forms for the stated obligation

Aon describes its global construction practice designs and places risk solutions and uses broking experience and a global network across construction insurance lines. For construction surety, this is evidence of Aon’s brokered market offering; the page does not identify the insurer for a buyer’s placement. Harper describes four categories of bonds: license and permit bonds required by a state or city, contract bid/performance/payment bonds, DMV dealer bonds placed with its garage program, and court or fiduciary bonds for estate or court obligations. A bond protects the obligee under the named obligation, so compare the required form and conditions against the contract or license before choosing a route. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

### Applicant profile and service model

Aon identifies its global construction and infrastructure practice as serving contractors, owners, developers, engineers, architects, designers, financiers and investors, and says it works with organizations of varied sizes and complexity. Harper identifies bonds are required across many industries and use cases, naming auto dealers, contractors and notaries as examples of businesses that need them for licenses, permits or contracts. A contractor or business should ask whether its trade, financial profile and bond amount fit the stated market and what documentation will be needed. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") [6](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

| Risk Services | Aon describes project risk-advisory services to understand project-specific risks and develop risk-transfer, management or mitigation strategies. It also describes a global construction team and market access. These are company-reported brokerage and advisory services, not coverage benefits. [3](https://www.aon.com/en/capabilities/risk-transfer/construction-and-infrastructure-insurance-and-risk-management "Construction and Infrastructure Insurance and Risk Management") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | Harper says it places bonds alongside the insurance program they usually travel with, rather than as a bond-only transaction.

| How to Apply | Confirm in your quote. | Harper says most license and permit bonds issue the same day or the next day, while contract bonds take longer because the bond company reviews the job first; it asks for the deadline and says it works to it. [6](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance") (Evidence: Company-reported; scope: Surety bonds FAQ 'How fast can I get a bond?'; timing is a company statement, not a guaranteed turnaround..) |
