Letter of Bondability in Texas
What Is a Letter of Bondability?
A Letter of Bondability is an official document issued by a surety company confirming a contractor’s established line of credit and financial standing for bonding purposes. It demonstrates that a contractor has been pre-qualified for a specific bonding capacity—showing both credibility and financial stability.
This letter is often requested when beginning new relationships with
vendors, municipalities, or project owners and is used to verify that a contractor can obtain payment and performance bonds when required.
Why It Matters
Many municipalities and vendors require proof of bondability before engaging in contract negotiations or awarding new projects. A Letter of Bondability provides reassurance that your company is capable of fulfilling contract and bonding obligations.
It serves as a powerful tool for building trust, particularly when entering new markets or bidding for larger projects. By providing this letter early in the process, contractors can streamline approvals, demonstrate professionalism, and strengthen their competitive position.
What the Letter Includes
A typical Letter of Bondability contains:
- The surety company’s name, rating, and financial strength (for example, AM Best A “Excellent”).
- The contractor’s approved single project and aggregate bonding capacity.
- A statement clarifying that the letter is informational, non-binding, and not a bid bond.
- Contact information for the underwriting representative.
This letter essentially functions as a
pre-approval indicator of a contractor’s ability to secure bonds when needed.

Frequently Asked Questions About Letters of Bondability
What’s the difference between a Letter of Bondability and a Bid Bond?
A Letter of Bondability simply confirms your bonding capacity; it is not a guarantee of future bond issuance. A bid bond, on the other hand, is a legally binding document submitted with a bid to guarantee performance if awarded.
Who issues the Letter of Bondability?
The letter is issued by a surety company—often through your broker, like Ironwood Insurance—and signed by a contract underwriter who has reviewed your bonding line and financials.
How long is a Letter of Bondability valid?
Most letters remain valid for 30 to 90 days, depending on the surety company’s policy and any changes in financial standing. A new letter can be requested if your bonding line or company details change.
Why should I request a Letter of Bondability before bidding?
Having the letter on hand proves your legitimacy and financial readiness to potential clients. It can expedite vendor approvals and help you win projects that require proof of bonding capacity.
