FAQs

Common questions.

Does Colorado law require supply bonds?

Usually the contract or the buying agency sets it, not a statewide law. The bid or contract documents state the amount.

What does it cost?

You pay a premium, not the bond amount. The surety sets the premium after it reviews your application, usually as a percentage of the bond amount. We show you the terms before you commit.
