Cost Plus Billing
What is Cost Plus Billing?
Cost Plus Billing in the construction industry refers to a method where the customer agrees to cover the actual costs, expenses and other direct costs of the construction project plus an additional sum for contractor’s overhead and profit. These typically include costs of materials, labor, and subcontractor charges. The agreement clearly establishes and defines what is constituted as cost, the overhead percentage, and the profit percentage, reducing the risk of any surprise costs. Essentially, the 'Cost' represents the direct costs of the construction, while the 'Plus' is the contractor's fee and is usually agreed upon as a fixed percentage of the total costs or as a target price with a shared savings clause.

What is Overhead Allocation?
Overhead Allocation in the construction industry refers to the process of distributing indirect costs or overheads related to a project, amongst the various direct cost items within the project. This process allows all associated project costs to be accurately reflected, providing a holistic understanding of a project's total expenses. Overhead costs could include equipment rents, electricity, insurance costs, etc. The allocation can be based on certain criteria like the rate of resource consumption. It's a fundamental aspect of financial management, allowing the accurate pricing of projects, assisting in budgeting, and providing key insights that can guide decision-making.
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, andÂ
- 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 an Estimate?
An estimate in construction is a calculated projection of the costs, time, and resources required to complete a specific project or scope of work. It includes direct costs like labor, materials, and equipment, as well as indirect costs such as overhead, insurance, and profit margins.Â
Construction estimates serve as the foundation for project planning, budgeting, and decision-making, helping both contractors and clients understand the financial commitment required. Estimates can range from rough preliminary assessments to detailed breakdowns that are often refined as project details become clearer or circumstances change.
Accurate estimating is essential for subcontractors to win profitable work while maintaining healthy margins. Many successful subcontractors develop standardized estimating processes that incorporate historical cost data, current market rates, and lessons learned from previous projects to improve bid accuracy and build credibility with general contractors.
