Commercial Bid Bond vs Payment Bond vs Performance Bond Matrix
Why this matters
A trade contractor that has only ever worked direct-to-owner residential is bidding a public project, a federally funded project, or a private commercial GC's prime contract for the first time and is being asked for bonds. The three names (bid, payment, performance) describe three different instruments that secure three different obligations at three different points in the project. Confusing them, or telling the customer "I can get a bond" without knowing which one and at what penal sum, is the path to losing the bid (or, worse, winning a bid you cannot bond). This article is the field reference.
The three bonds
A surety bond is a three-party instrument: the obligee (the party protected), the principal (the contractor), and the surety (the bonding company that pays the obligee if the principal defaults, then collects from the principal). Each of the three commercial construction bonds protects a different obligation.
Bid bond: protects the obligee against the principal's failure to enter the contract at the bid price. If the contractor bids, wins, and then refuses to sign or cannot provide the required performance bond, the bid bond pays the obligee the difference between the original bid and the next bidder's bid, up to the bond's penal sum. Penal sum is typically 5 to 10 percent of the bid amount.
Performance bond: protects the obligee against the principal's failure to complete the work per the contract. If the contractor walks, the surety completes the work (either by financing the contractor, taking over and re-letting the work, or paying the obligee the cost to complete), up to the penal sum. Penal sum is typically 100 percent of the contract amount.
Payment bond: protects subcontractors, material suppliers, and laborers from the principal's failure to pay them. If the principal does not pay a sub or supplier, the sub or supplier makes a claim against the payment bond. Penal sum is typically 100 percent of the contract amount.
The performance bond and payment bond are often issued together as a "P&P bond" on a single rider.
When each bond is required
Federal projects: the Miller Act (40 USC Sections 3131 through 3134) requires a payment bond and a performance bond on federal construction contracts above $150,000 (the statutory threshold). For contracts between $35,000 and $150,000, the contracting officer requires payment protection in an alternative form. Sub-tier subcontractors on Miller Act projects do not have lien rights against the federal property; the payment bond is the substitute remedy.
State public projects: most states have a "Little Miller Act" that mirrors the federal statute for state-funded projects, with state-specific dollar thresholds and bond percentages.
Private commercial: bonds are required by the owner or by the prime contractor at the prime's discretion. Common triggers: project size, contractor's bonding history, owner's lender requirement, prime contractor's risk policy.
Public works at the local level: counties and municipalities frequently require bonds on contracts above a local threshold.
Surety underwriting
A surety bond is not insurance; it is a credit instrument. The surety expects to be reimbursed by the principal for any payout. Underwriting evaluates:
- Capacity: the contractor's financial capacity to perform the work.
- Capital: the contractor's net worth and working capital.
- Character: the contractor's history of completed work and history of claims.
The surety reviews the contractor's three most recent years of CPA-prepared financial statements, work-in-progress (WIP) schedule, banking relationship, and personal financial statement of the owner. Personal indemnity from the owner is the standard for closely held trade contractors; the owner is on the hook personally for any surety payout.
Surety capacity (the total bonded backlog the surety will support) typically runs 10 to 15 times the contractor's working capital and 5 to 10 times tangible net worth. The contractor's "single bond limit" (the largest project bondable) is usually 25 to 50 percent of the total capacity.
A bond producer (surety agent) packages the underwriting submission. Establish the relationship a year before the first bond is needed; the surety wants to know the contractor before it needs to write a bond.
Bond rates
Bond premium rates are filed with state insurance departments and are not negotiable in the way insurance premiums are. The premium is a percentage of the bond's penal sum, on a sliding scale by contractor size and project size. Typical commercial bond rates for an established contractor run within a published rate range; new contractors and high-risk contractors pay rate-and-a-half. The premium is paid once at bond issuance, not annually.
Reading the bond form
Standard bond forms used in the industry:
- AIA A310 Bid Bond.
- AIA A312 Performance Bond and Payment Bond.
- ConsensusDocs 260 Performance Bond and ConsensusDocs 261 Payment Bond.
- SF 25 (Standard Form 25) for federal performance bonds.
- SF 25A for federal payment bonds.
Owner-drafted bond forms are common on private work and are heavily one-sided. Read the bond form before signing; the surety's underwriter reads it too and may require modifications before approving.
Practical contractor takeaways
If the contractor is exploring commercial or public work, build the surety relationship and capacity now, not when the first bid is on the table. The surety underwriting process takes weeks at minimum; a bid bond requested the day before bid day will not be issued.
Maintain CPA-reviewed or CPA-audited financial statements (reviewed at minimum; audited for larger capacity). Self-prepared financials shrink surety capacity sharply.
The personal indemnity is real. A bond claim that exceeds the corporate net worth comes to the owner personally. Build the corporate financial cushion before chasing bonded work that stretches capacity.
