A general contractor who already carries a performance bond on one project assumes she needs the same thing to chase a new municipal contract. She doesn’t. The invitation to bid asks for a 5% bid guarantee, and the performance obligation won’t come into play unless she wins. Buying the wrong instrument at the wrong moment is a common and expensive mistake, because the word “bond” covers several very different promises. Picking the right one starts with being honest about where you actually stand on the project.
Match the bond to the stage you’re in
Surety bonds track the life of a job. A bid bond belongs to the pursuit phase, when you’re competing for work and haven’t signed anything. A performance bond and a payment bond both belong to the construction phase, after you’ve been awarded the contract and the obligations are real. Trying to decide “which bond” in the abstract leads nowhere. Ask instead: what stage am I in, and what promise does someone need me to back up right now? The answer usually points to a single correct instrument.
Just bidding, or already awarded the contract?
If you’re still submitting proposals, the owner’s concern is narrow. They want assurance that if you win, you’ll actually sign the contract at the price you quoted and furnish the bonds they require. That’s a bid bond. It’s small, it’s cheap, and it expires the moment the award is settled one way or another.
Once you’ve signed, the owner’s concern changes entirely. Now they care whether the work gets finished and whether the people who supply labor and materials get paid. The bid bond has done its job; what matters from here is the performance and payment side. Many first-timers conflate the two and either skip the bid bond or expect it to keep protecting them through construction. It does neither.
When a performance bond alone leaves someone exposed
A performance bond guarantees one thing: that the contract will be completed according to its terms. If you default, the surety steps in to see the work through or compensate the owner. What it does not do is guarantee that your subcontractors and material suppliers get paid. That gap matters more than it sounds. On private projects especially, an unpaid subcontractor can file a mechanic’s lien against the property even though the owner already paid the general contractor. The owner holds a performance bond and still faces a claim on their own title. A performance bond alone protects completion, not the payment chain beneath it.
Why owners often insist on P&P bonds instead of a single guarantee
This is why sophisticated owners and lenders rarely accept a performance bond by itself. Pairing it with a payment bond closes the lien exposure: the payment bond gives unpaid subs and suppliers a surety to claim against instead of the project. Lenders in particular treat the pair as a condition of funding, and if you’re financing a build you’ll find that P&P bonds are often non-negotiable before a loan closes. For public work, statute frequently requires both anyway. When someone asks for “a bond” on a funded or public job, they usually mean the combination, even if they only said one word.
Weighing a standalone bond against a combined package
So when is a single bond genuinely enough? Occasionally a smaller private owner cares only about completion and has no lender dictating terms. In that narrow case, a standalone performance bond may satisfy everyone. But the premium savings are modest, because sureties price the two together as a single risk, and the uncovered payment exposure can dwarf whatever you saved. Unless the contract documents explicitly call for performance only, treating the combined package as your default is the safer instinct. Read the bond requirement in the contract word for word before you assume which one applies.
A quick checklist to settle on the right choice
Run through four questions. Have you signed the contract yet, or are you still bidding? If bidding, you need a bid bond and nothing more. If awarded, does anyone fund or own the project who could be hurt by unpaid subs? If yes, assume performance and payment together. Does the contract or statute name a specific bond type? Follow it exactly. Is the penal sum tied to the contract value, and does the owner find your surety acceptable?
Pull out the actual bid or contract documents and read the bonding clause line by line today; that single step tells you which instrument the job in front of you truly requires.
