Bidding Mistakes Beginners Make

Most first-year losses come from a handful of avoidable bidding errors.

The classics

• Scope gaps — assuming another trade covers something nobody priced (demo, firestopping, cleanup). Read scope carefully; clarify in writing.
• Bidding too low to "get the job" — winning at a loss is worse than not winning. Know your true costs.
• Forgetting overhead and profit — a price that only covers material and labor bankrupts you slowly.
• Math/unit errors — a transposed number or wrong unit can cost thousands.
• Ignoring the fine print — missing liquidated damages, bonding, retainage, or a brutal schedule.
• Unbalanced/last-minute subs — taking a too-good-to-be-true sub quote that's missing scope.

Protect yourself

Use a checklist, leave time to review, document assumptions and exclusions, and walk away from bad work. No job is better than a job that loses money.

Takeaway: Avoid the rookie killers — scope gaps, low-balling, forgetting overhead/profit, math errors, and skipping the fine print — by using a checklist, documenting assumptions/exclusions, and being willing to walk away from a money-losing job.

Educational overview — bid requirements vary by owner and jurisdiction; always follow the specific invitation-to-bid and instructions to bidders.
