Subcontractor Bid Shopping Prevention Guide 2025: Protect Your Bids
Understand bid shopping practices and how to protect yourself. Learn strategies for subcontractors to avoid being shopped and for primes to maintain ethical practices.
Quick Answer: What is Bid Shopping?
Bid shopping occurs when a prime contractor uses one subcontractor's bid to pressure other subs to lower their prices after the bid deadline. It is unethical, often illegal in public work, and damages the industry. Subcontractors can protect themselves through timing strategies, bid listing laws, and selective prime relationships.
What is Bid Shopping?
Understanding the forms bid shopping takes:
Bid Shopping
Prime uses low sub bid to negotiate even lower prices from other subs after bid deadline.
- • “Can you beat $X?”
- • Disclosing competitor pricing
- • Post-award negotiations
- • Pressuring for reductions
Bid Peddling
Subcontractor offers to undercut competitors after learning their prices.
- • “I will beat any price”
- • Post-bid price reductions
- • Approaching losing primes
- • Last-minute low-balls
The Distinction
Legitimate post-bid negotiations (scope clarifications, value engineering, schedule adjustments) are different from bid shopping. The key is whether competitive pricing information is being used to pressure lower bids.

Protection Strategies for Subcontractors
Time Your Bid Submission
Submit bids close to deadline to minimize shopping time. Many subs submit within the final 30-60 minutes. Electronic submission makes this easier.
Build Relationships with Ethical Primes
Work with general contractors known for ethical practices. Your reputation and theirs become mutually beneficial. Avoid known shoppers.
Include Scope Limitations
Make your bid specific enough that apples-to-apples comparisons are difficult. Include detailed scope, exclusions, and qualifications.
Document Everything
Keep records of all bid submissions, communications, and any shopping attempts. This documentation may be needed for legal action.
Know Your Rights
Understand bid listing laws in your state. Know when you have legal protections and be prepared to enforce them.
Legal Protections
Various laws and practices protect against bid shopping:
Bid Listing Laws
Many states require primes to list subcontractors in their bids for public work. Once listed, the sub cannot be changed without good cause.
States with Strong Laws
- • California (strongest)
- • New York
- • Massachusetts
- • New Jersey
- • And many others
Typical Protections
- • Must list subs over threshold
- • Cannot change without cause
- • Process for substitution
- • Penalties for violations
Other Legal Remedies
- • Promissory estoppel: If prime relied on your bid, they may be bound
- • Tortious interference: Action against parties who interfere with contracts
- • Industry associations: Report unethical practices to AGC, ASA, etc.
- • Licensing boards: Some states can discipline for unethical practices
Ethical Practices for Prime Contractors
Do
- ✓ Honor sub bids used in your proposal
- ✓ Negotiate scope, not just price
- ✓ Maintain confidentiality of pricing
- ✓ Build long-term relationships
- ✓ Pay subs fairly and promptly

Avoid

- ✗ Last-minute price demands
- ✗ Using bids to get free estimates
- ✗ Switching subs for minimal savings

Long-Term Benefits of Ethics
Ethical primes attract better subcontractors, get more competitive bids, experience fewer disputes, and build reputations that win work. Short-term savings from shopping often cost more in the long run.

Frequently Asked Questions
Should I refuse to rebid if shopping is suspected?
Consider standing firm on your original bid. You can decline to reduce pricing without scope changes. However, weigh relationship and future work implications.
Does bid shopping happen on federal contracts?
Yes, though federal regulations discourage it. The FAR requires primes to pay subs fairly. Severe cases can involve false claims issues. Federal work may have less shopping due to oversight.
How can I tell if a prime is a shopper?
Ask other subcontractors about their experiences. Industry associations often have informal knowledge. A prime's reputation usually becomes known over time.
What if my only option is working with shoppers?
Build in appropriate margin, submit late, and document everything. Work to develop relationships with ethical primes over time. Consider whether the work is worth the cost.
