## 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. [8](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [9](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds") [10](https://www.law.cornell.edu/uscode/text/40/3131 "40 U.S. Code § 3131 — Bonds of contractors of public buildings or works") [11](https://www.chubb.com/us-en/surety.html "Surety Bonds") [12](https://www.harperinsure.com/coverages/surety-bonds "Surety Bonds Insurance")

## What Are the Key Differences Between Marsh McLennan Agency and Nationwide Surety Bonds?

### Commercial Obligations and Contract Bonds

Nationwide describes commercial surety as a guarantee that a principal will meet financial-responsibility or compliance obligations. Marsh McLennan Agency names commercial license-and-permit bonds as well as contract surety for project obligations. That gives MMA’s overview a named construction-related track, while Nationwide’s summary frames the commercial obligation more generally. If the obligee requires a particular bond form, compare its wording with the actual forms each provider can place; neither broad product description establishes that every obligation is eligible. [3](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA") [7](https://www.nationwide.com/business/insurance/bonds/ "Commercial Surety Bonds")

### Underwriting and Starting a Quote

Nationwide says bond form and underwriting depend on the obligation and applicant, and directs prospective buyers to contact an agent or request a quote. MMA likewise invites a conversation with an adviser or surety specialist, while its overview describes customized support for complex risks. Neither page gives a self-service binding route or universal timeline. A buyer can use either contact to identify the right market, but should ask how much financial information, indemnity, and obligee documentation the specific request will require. [3](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA") [7](https://www.nationwide.com/business/insurance/bonds/ "Commercial Surety Bonds")

- Which commercial bond form, penal sum, and underwriting documents will Nationwide require for your obligee? [7](https://www.nationwide.com/business/insurance/bonds/ "Commercial Surety Bonds")
- Which MMA specialist and surety market will review the obligation, and what financial or indemnity material should you prepare? [3](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk | MMA")
