What is Overbilling?

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.

With Siteline, you can easily track whether you’re billing in excess of your costs by pulling your month-to-month incurred costs and comparing them against your billing progress. This real-time visibility helps ensure you’re billing appropriately while maintaining realistic profitability expectations.

Profit Fade

What is Profit Fade?

Profit Fade, in the construction industry, refers to a situation where the projected profit margins on a project decrease as the project progresses. This typically occurs when actual job costs exceed the initial estimates, resulting in a decrease in the anticipated profit. For instance, unforeseen complications, increased material prices, labor overruns, or errors in bidding can all contribute to profit fade. It's essential for construction firms to have systems in place for tracking job costs and updating profit projections to manage profit fade effectively. Proactive financial management can minimize the impact of profit fade and maintain project profitability.

Conditional Lien Waiver

What is a Conditional Lien Waiver?

A Conditional Lien Waiver is a legal document used in the construction industry that states a contractor, subcontractor, or supplier will give up or waive their right to place a lien on a property, under the condition they receive their expected payment. This waiver serves as a protection mechanism for the party responsible for payment, ensuring that once the payment is made, no future lien could be placed on the property for the services or materials provided.

Surety

What is a Surety?

A Surety, in the context of the construction industry, refers to a third-party entity that provides a guarantee or assurance to a project owner or client that a contractor will fulfill all obligations outlined in a contract. It is typically seen in the form of a surety bond, which protects the project owner against financial losses if the contractor fails to perform or complete the project as per their contractual obligations. The surety bears the risk of contractor's default and is legally responsible to either finance the project to completion or find an alternative contractor. The use of surety is common in projects, especially public construction projects, to ensure their successful completion.
