Overbillings
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.

What is a Lien Waiver?
A lien waiver is a legal document used in the construction industry that is often exchanged between parties involved in a construction project. This waiver essentially absolves or "waives" the claimant's (typically a project participant like a contractor, subcontractor, or supplier) right to impose a lien on the property for the amount they have been paid. It's often used upon payment to ensure that the payer is protected from double payment or any encumbrances on the property related to payment disputes. There are four general types of lien waivers: conditional and unconditional, each of which can be used for progress or final payment. Each type has its own legal implications, so it's important to understand them fully before signing.
What is Working Capital?
Working capital, in the context of the construction industry, is a financial metric which represents the operating liquidity available to a business. It is essential for managing the day-to-day expenses that arise during construction projects. It is calculated by subtracting the current liabilities (what the firm owes within a year) from the current assets (what the firm owns or can quickly convert into cash within a year). These generally include accounts receivable, inventory, and cash on hand. A positive working capital is critically important in the construction industry as it suggests that the company has enough resources to complete current projects without needing additional financing. It also underscores the firm's financial stability in managing its short-term obligations while still growing its operations. Without ample working capital, construction companies may encounter challenges in purchasing materials, paying subcontractors or meeting other immediate expenses.
What is Work in Progress (WIP)?
In construction accounting, work in progress (WIP) refers to the value of construction projects that have started but are not yet completed at a specific point in time. It represents the costs incurred and revenue earned on ongoing projects. Key aspects of WIP include everything from cost tracking, revenue recognition, billing cycles, and financial reporting to schedule monitoring, change order management, retainage tracking, and tax planning.
As mentioned in our WIP Accounting Principles blog post, understanding WIP is a critical component of running a profitable business. This is because it offers several key benefits:
- Financial Health Tracking: WIP reports help to identify potential issues before they spiral to keep projects on track. For example, it can help spot gross margin slippage early on and alert project managers that they need to course correct.
- Cost Management: Comparing work completed to the budget spent will alert subcontractors if project expenses are running too high. For instance, if only 25% of the work is complete, but 40% of the project labor budget has been used, it indicates the need to reel in costs.
- Compliance: WIP reports help ensure that invoices align with work completed, reducing the risk of pay app rejections
- Profitability: WIP reports systematically account for project-related costs and revenue. This gives subcontractors a clear picture of which projects are most profitable and spot trends to help determine the best project types for the business.
Effective WIP management is crucial for subcontractors' financial health. Modern billing and cash flow forecasting software, like Siteline, enhances WIP accounting by centralizing data to increase financial visibility, improve informed decision-making, and optimize cash flow.
