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.

Lien

What is a Lien?

A lien, particularly in the construction industry, is a legal claim or right that a contractor, sub-contractor, or supplier places on a property at which they have rendered services or supplied materials, but haven't been paid. Essentially, it's a security interest granted over an item of property to secure the payment of a debt or performance of some other obligation. If the property owner does not fulfill the financial obligation, the lien holder may seek legal action to enforce their rights and might even result in the compulsory selling of the property to pay off the debt. Liens are crucial elements in construction law, ensuring parties are fairly compensated for their work and supplies provided.

Request for Proposal (RFP)

What is a Request for Proposal (RFP)?

A Request for Proposal (RFP) within the construction industry is a comprehensive document that outlines the specifics about a particular construction project. It's a call to bidders, helping interested contractors and construction firms understand the project details, timelines, expectations, and criteria for selecting the winning bid. An RFP in the construction industry typically includes information such as project scope, schedule, required materials, budget, and other relevant factors. It acts as a formal invitation, allowing companies to bid on the project by proposing a plan that meets or exceeds the listed requirements. This inherently ensures competition, dedication towards the job and best value for money for the project owner.

Completed Contract

What is a Completed Contract?

A completed contract, in the context of the construction industry, is a concept relating to the financial recognition of a project. In specific accounting terms, it represents a method where all the costs and profit related to the contract are recognized only after the project has been finished and fully executed. This means neither revenues nor expenses are recorded in company books until all the work stipulated in the contract is fully accomplished. This approach contrasts with the percentage-of-completion method, which requires ongoing recognition of revenues and costs as the project advances. The completed contract method is often chosen for projects where outcome and costs are uncertain, essentially to prevent financial discrepancies.
