About Bid Builder Pro

Built to help small contractors quote with more confidence.

Bid Builder Pro is a free browser-based estimating resource created by Francis King. It helps small contractors organize labor, materials, overhead, margin, deposit, optional tax, and contract language before sending a price to a client.

The site is designed as both a practical tool and an educational contractor pricing resource. It is not a law firm, accounting firm, tax advisor, or insurance advisor. Contractors should use professional judgment and confirm local requirements before relying on any estimate or contract language.
