What is a Final Lien Waiver?

Underbilling refers to a scenario in the construction industry where the actual costs incurred on a project surpass the billed amount for a specific time period. Often occurring unintentionally due to unexpected cost variations, it results in a deficit situation for the contractor. It is essentially an imbalance where the contractor has delivered more work or materials than they have billed the client for. Underbilling can strain cash flow and disrupt project schedules if not addressed promptly. While this might prove beneficial to the client in the short term, contractors need to ensure that they identify and rectify underbilling to maintain project profitability and financial stability.

A Performance Bond is a type of surety bond issued by an insurance company or a bank to guarantee satisfactory completion of a project by a contractor. In the construction industry, a Performance Bond is often required to protect the client if the contractor fails to complete the contract or does not meet the agreed standards or time frame in performing the project. It is essentially a safeguard tool that ensures the project owner will not incur financial loss due to the contractor's inability to fulfill the contract. This bond provides assurance that the contractor has the necessary resources and competencies to execute the project according to the stipulated terms.

Overbilling (or billing in excess of costs) occurs when you’ve invoiced your client for more work than you’ve actually completed or incurred costs for. In other words, it represents getting paid ahead of your work schedule.

Here’s how it works: If you’re a concrete subcontractor on a $100,000 job and you bill 50% upfront ($50,000) but have only completed $30,000 worth of work, that $20,000 difference is your billings in excess of costs. You owe your client that work, and until you complete it, that $20,000 remains as a liability on your balance sheet.

For subcontractors, understanding billing in excess of costs is essential because it can be a strategic cash flow tool when used carefully. For example, when bidding on a job, you can be smart about how you structure your schedule of values (SOV)—breaking work down into more detailed line items that allow earlier billing. However, this strategy requires regular monitoring to ensure:

• Your billing somewhat aligns with your actual percentage complete, and 
• The remaining contract value will still cover your remaining costs.

The biggest risk of overbilling is thinking your margins look better than they are, simply because you’re collecting cash faster. Surety companies and lenders also scrutinize overbillings closely, as excessive amounts can signal poor project management or potential cash flow problems down the road.
