You have ever wondered how to avoid underbidding in general contracting? The short answer is this: know your real costs, plan for surprises, and show clients why your work is worth the price. Underbidding offering a price that;s too low might win you the job, but it can quickly.
Here, you will learn why underbidding happens, what it costs you, and the exact steps to stop it from hurting your business. By the end, you will know how to create bids that win work, protect your profit, and build a strong reputation. The goal is to help you win jobs that keep your business strong, not struggling.
Key Points
- Winning a job at the wrong price can drain cash, lower quality, and harm your reputation.
- Include labor, materials, overhead, and a 10–15% contingency in every bid.
- Track past project costs, use estimation software, and monitor expenses in real time.
- Highlight quality, reliability, and long-term savings to justify higher bids.
- Sustainable bidding keeps your business profitable, competitive, and trusted in the market.
What is Underbidding in Construction?
In general contracting, bidding is how you compete for projects. You estimate the cost of labor, materials, equipment, and overhead, then submit a price to the client. If your price is lower than your competitors, you might win the job. That sounds good until you realize you’ve promised to do the work for less than it will cost you. This is called underbidding, and it’s one of the biggest traps in the construction industry.
Why Contractors Underbid
Underbidding doesn’t usually happen because contractors want to lose money. It happens because the numbers are not complete or the pressure to win is too strong.
One of the biggest causes is incomplete cost estimation. A contractor might add up labor and materials but forget about overhead . These fixed costs don’t go away just because they’re not tied to one specific job. Missing them in the bid means you’ll be paying them out of your pocket later.
Many also skip adding a contingency, a safety buffer for unexpected problems like weather delays or sudden price hikes on materials. Without it, even small surprises can eat up all the profit.
Inexperience is another significant factor. New contractors, or those entering a new type of project, often don’t have enough historical data to guide their pricing. They might not know how long a task really takes or how much certain materials usually cost once the job begins. Without past project records to compare against, estimates become guesses.
Then there’s fear-based pricing, which is especially common in slow economies or crowded markets. When jobs are scarce, some contractors lower their bids to make sure they get the work.
How to Avoid Underbidding in General Contracting – Strategies
Avoiding underbidding is not about guess work but means building your bid on solid, detailed information. When you know your actual price and present your value clearly, you can win work without putting your business at risk. Here’s how to make that happen.
Conduct Thorough Cost Estimation
Start by breaking the project into every possible expense. Include fixed costs like equipment payments, rent, and insurance, as well as variable costs like labor, materials, and subcontractor fees. Don’t forget overhead and indirect expenses (things like utilities, office staff salaries, and marketing) because they still need to be paid, even if they’re not tied to a single project. Create a line-item breakdown for each part of the job so nothing gets overlooked.
Leverage Historical Project Data
Keep records of how long tasks took, how much materials cost, and where delays happened. This historical data lets you compare your estimates with real outcomes so your future bids are based on facts, not guesses. For example, suppose you know a particular supplier’s prices went up 5% last year. In that case, you can plan for similar increases in your new bid.
Build in Contingencies
Construction rarely goes exactly as planned. A sudden storm, a backordered material, or an unexpected permit requirement can all cause delays and extra costs. Protect yourself by adding a 10–15% contingency buffer to your total estimate. This way, you have room to handle surprises without dipping into your profit.
Focus on Value, Not Just Price
Clients don’t always choose the lowest bid. They select the bid that gives them confidence. Highlight what sets you apart: your quality of work, your safety record, your ability to finish on time, and your track record of satisfied clients. Show how your bid saves money in the long run, even if it’s not the cheapest upfront.
Use Technology for Accuracy
Modern construction tools make estimating more precise. Estimation software can calculate costs faster and reduce human error. Predictive analytics can forecast price changes in materials, while job costing tools can track expenses in real time. These tools not only save you time but also make your bids more accurate and competitive.

Strengthen Financial Resilience
Even with the best planning, a project might run into cash flow challenges. Keep healthy cash reserves so you can cover expenses without relying on risky short-term loans.
Improve receivables management by sending invoices promptly and following up quickly on late payments. Strong financial health means you can focus on doing great work instead of scrambling for the next paycheck.
The Consequences of Underbidding
Underbidding might be a smart move. But the relief doesn’t last. It starts draining your bank account instead of building it.
Cashflow Burden
In the short term, underbidding creates a severe cash flow strain. You may find yourself borrowing money, delaying supplier payments, or handling invoices to keep the project moving. When there’s no financial cushion, even small surprises like a delivery delay or a price jump in materials can throw the whole job off balance.
Reputational Damage
In the long term, the damage goes deeper. To make up for lost profit, you might cut corners: using cheaper materials, reducing labor hours, or skipping necessary safety measures. This almost always lowers the quality of the work, which clients notice. Over time, that leads to reputational damage.
Decline in Prices
When contractors keep underbidding to win work, the entire market suffers. Prices across the industry drop to unsustainable levels, creating unhealthy competition. According to construction cost analysis from Dodge Data & Analytics, overly aggressive bidding can cut average project profit margins from the healthy 8–12% range down to as low as 2–3%. At that point, even one mistake can wipe out a contractor’s earnings for the job.
FAQs
How do I calculate my break-even point for bids?
Your break-even point is the lowest price you can charge without losing money. To find it, add up all your project costs such as labor, materials, equipment, permits, and overhead (like insurance, rent, and utilities). Then divide that total by the number of units or hours of work for the job. This gives you the baseline price you must meet to cover your expenses. Any bid below this number will cost you money.
