Bid Bonds

Updated: 06 May 2026

What Does Bid Bonds Mean?

Bid bonds are financial guarantees that contractors are often required to submit along with their bids for construction projects. These bonds act as a form of insurance for the hiring company, protecting it from significant losses if the contractor abandons the project or fails to complete it properly. In the context of insurance, insurers frequently provide bid bonds to contractors. Bid bonds are one piece of a contractor’s overall insurance and bonding setup, which usually includes general liability, workers’ compensation, and other forms of business insurance.

Insuranceopedia Explains Bid Bonds

Developers often require bid bonds from contracting companies to ensure that the contractor has sufficient cash flow to sustain operations throughout the project. Construction projects can be extremely costly, and bid bonds help guarantee that the contractor will be able to continue paying employees and covering other essential expenses for the project’s duration. If a project halts midway, it could result in significant financial losses for the developer. Bid bonds, therefore, serve to mitigate this risk. Bond premiums are usually a smaller line item for a contractor than ongoing general contractor insurance costs, but both factor into how a company prices a bid.
