Surety bonds for small businesses: types, costs and SBA guarantees

If you bid on government work, larger construction projects or some licensed trades, you may be asked for a surety bond. Bonds can open the door to bigger contracts, but they work very differently from insurance, and it is important to understand what you are promising.

What a surety bond is

A surety bond involves three parties:

The SBA explains that surety bonds help small businesses win contracts by giving the customer a guarantee that the work will be completed, and that many public and private contracts require them.

Bonds are not insurance

Insurance protects you against losses. A bond protects the obligee. If you fail to meet the obligation and the surety pays a claim, the surety will normally expect you to repay it, often under an indemnity agreement you sign when you get the bond. Read that agreement carefully. You still need insurance; see general liability insurance.

Contract bonds and commercial bonds

The SBA describes two broad groups:

Commercial bonds are often tied to licenses, such as some contractor licenses, and to certain public officials, such as notaries in states that require a notary bond.

Types of contract bonds

The SBA lists these categories:

How sureties decide

Before issuing a bond, a surety assesses whether you can complete the work and pay your obligations. Expect questions about:

Good bookkeeping and up-to-date financial statements make bonding easier.

What bonds cost

Bond premiums are usually a percentage of the bond amount, set by the surety based on the bond type and your risk profile. Shop around through surety agents, and remember to build bond costs into your bids.

SBA surety bond guarantees

The SBA guarantees bid, performance, payment and ancillary bonds issued by certain surety companies. This lets those companies offer bonds to small businesses that might not meet their normal criteria. The process the SBA describes:

  1. A small business contacts an SBA-authorised surety agency.
  2. The agent secures bond approval from an SBA surety partner.
  3. The SBA guarantees the bond for a qualified small business.

The SBA charges a guarantee fee on performance and payment bond guarantees, which it states as 0.6% of the contract price, and no fee for bid bond guarantees. The SBA guarantees contract bonds but not commercial bonds. Check eligibility and current terms on the SBA's surety bonds page.

Managing bonds

Bonds, insurance and certificates

Customers may ask for both a bond and proof of insurance. A certificate of insurance shows your insurance; a bond is a separate document from the surety.

Getting bonded for the first time

If you have never been bonded, start before you need a bond for a specific bid. Talk to a surety agent, prepare financial statements and a list of completed projects, and ask what bonding capacity you could get. Starting with smaller bonded jobs builds a track record that makes larger bonds easier later.

Questions to ask a surety agent

A surety bond guarantees your obligations to the customer or agency, not to you; know whether you need a contract or commercial bond, prepare clean financials, price bonds into bids, understand the indemnity you sign, and ask SBA-authorised agents about guaranteed bonds if you struggle to get bonded.

Questions people ask

Is a surety bond the same as insurance?

No. Insurance protects you; a bond protects the party requiring it. If the surety pays a claim, you are usually expected to repay it.

What are the main contract bonds?

Bid bonds, payment bonds, performance bonds and ancillary bonds.

What is a commercial bond?

A bond required by a government agency to make sure laws and regulations are followed, protecting the public against things like fraud.

Can the SBA help me get bonded?

The SBA guarantees certain contract bonds issued by participating surety companies for eligible small businesses.
