Surety bond
A third-party guarantee from a surety, obtained for an annual premium that is a fraction of the required amount. No cash is tied up.
Letter of credit
A bank instrument that lets the beneficiary draw funds on demand. The bank typically requires collateral or uses your credit line for the full amount.
| Feature | Surety bond | Letter of credit |
|---|---|---|
| Cash and credit impact | No collateral for most license bonds; premium only | Usually collateralized or counted against your bank credit line |
| Typical annual cost | A percentage of the required amount, set by underwriting | Bank fees plus the opportunity cost of tied-up cash or credit |
| How claims work | The surety investigates the claim before paying | The bank pays on a conforming draw, no investigation |
| Who stands behind it | A licensed surety carrier | Your bank |
| Effect on borrowing capacity | Generally none | Reduces available credit while outstanding |
Best for
Pick Surety bond
A surety bond fits most businesses that qualify for underwriting, because it satisfies the requirement without tying up cash or bank credit.
Best for
Pick Letter of credit
A letter of credit fits a business that cannot obtain bonding on workable terms, or whose obligee only accepts a bank instrument.
Renting a guarantee versus parking your own money
Both instruments give the beneficiary security, but they load the cost differently. A surety bond is a third-party guarantee: you pay an annual premium, the surety underwrites you, and your cash and bank lines stay free. A letter of credit is your own money or credit standing behind the obligation: the bank typically requires collateral or counts the full amount against your credit line for as long as the letter is outstanding, and charges issuance and renewal fees on top.
Claims behave differently too. A surety investigates whether a claim is valid before paying, which protects you from unfounded draws. A bank pays a conforming letter-of-credit draw on demand and asks questions later. That is why sureties can offer bonds without collateral to qualified applicants, and why a letter of credit is usually the costlier way to satisfy a requirement that accepts either.
When a statute or obligee accepts both, price the two side by side: the bond premium against the bank fees plus what the tied-up cash or credit could otherwise do. Cornerstone Surety can quote the bond leg same day for most license requirements. See all bond types or get a bond quote.
Frequently asked
- Which is cheaper, a surety bond or a letter of credit?
- For most qualified applicants the bond is cheaper in practice, because the letter of credit ties up cash or credit for the full amount in addition to bank fees. Run both numbers for your specific requirement, since underwriting and bank pricing vary.
- Do regulators accept either one?
- Some statutes accept a bond, a letter of credit, or a cash deposit; others name only one instrument. The application checklist or statute wording controls, so confirm before you buy either.
- Does a letter of credit affect my ability to borrow?
- Usually yes. Banks typically count an outstanding letter of credit against your credit line or hold collateral for it, which reduces what you can borrow while it is in force.
