In construction accounting, understanding overbilling and underbilling is essential for contractors. While underbilling may lead to cash flow deficits, overbilling can have significant legal and financial consequences if not managed carefully. Contractors need to balance their billing practices to maintain healthy cash flow, adhere to contractual terms, and avoid unnecessary risk.
This article will explain what overbilling is, why contractors use it, and how it can affect your construction firm’s financial health and reputation.

What is Overbilling in Construction?
Overbilling occurs when a contractor invoices a client for more than the value of the work completed at that point. In Percentage of Completion (POC) Accounting, overbilling happens when the contractor charges for a portion of the project that exceeds the actual progress made.
For example, if a contractor has physically completed 40% of a project but invoices for 60%, the additional 20% is considered overbilled. This creates a situation where the contractor has billed more than the work completed, which results in a liability on the balance sheet (Billings in Excess of Costs and Estimated Earnings) and could lead to financial and contractual complications.
Why Do Contractors Use Overbilling?
While overbilling might sound like a risky practice, it can sometimes be a necessary financial tool to manage cash flow and ensure project continuity. Below are the key strategic reasons contractors utilize overbilling:
To Maintain Liquidity:
Construction projects often face inherent delays in client payments. Overbilling helps contractors secure upfront funds to cover immediate expenses like ongoing labor, materials, and mobilization costs, ensuring the project can continue smoothly without financial interruptions.
To Improve Working Capital:
Overbilling provides immediate, internal funding, reducing or eliminating the need for high-interest short-term loans or credit lines to cover initial project mobilization and procurement costs.
To Keep Projects on Schedule:
Access to upfront capital allows contractors to purchase materials and engage subcontractors quickly. This proactive funding helps mitigate delays caused by slow payments, keeping the project moving forward as planned.
While overbilling can provide short-term benefits, it must be done carefully to avoid financial mismanagement and potential issues with clients.
Why Contractors Should Be Careful with Overbilling
Although overbilling can help with cash flow management, if not done with proper oversight, it can lead to significant problems:
Legal Risks:
If overbilling violates the explicit terms of the contract, contractors could face legal action or penalties. Depending on the severity and contractual language, overbilling could be considered a breach of contract, leading to lawsuits and significant damage to the business's bonding capacity and reputation.
Damaged Client Relationships:
Billing significantly in excess of work completed can lead clients to feel overcharged or misled. This destroys trust, often leading to delays in future payments or the loss of future projects with that client. Maintaining transparency is key to avoiding these issues.
Impact on Future Cash Flow:
If overbilling is not accurately tracked, contractors might face a negative cash flow reversal when the project nears completion. Since little or no money will be due at the end, contractors may struggle to meet obligations or reinvest in subsequent projects.
How to Manage Overbilling Effectively
Managing overbilling effectively involves clear communication, accurate billing, and detailed tracking. Here are some key practices to avoid the negative consequences of overbilling:
Align Billing with Actual Work Progress
Make sure your billing is closely aligned with the actual physical progress of the project. Overbilling should be reserved only for securing initial mobilization costs or covering material costs allowed under the contract.
Best Practice: Utilize Job Costing and project management software to ensure invoices are tied directly to verified physical work completed.
Maintain Clear Communication with Clients
Transparency is essential. Always discuss billing milestones with your clients ahead of time and ensure they understand how billing relates to project progress, especially concerning materials stored on-site.
Best Practice: Develop a detailed project schedule that includes milestones and agreed-upon billing terms, and provide clients with regular progress reports.
Ensure Accurate Tracking of Costs
For accurate billing, ensure that your cost tracking is up-to-date and includes all project-related costs. Any discrepancy between your actual costs and billed amounts could lead to mismanagement.
Best Practice: Integrate Job Costing software with your Accounts Payable system to ensure real-time tracking of committed costs, preventing miscalculations.
Follow Contractual Terms Strictly
Review your contract and confirm that your billing schedule and the use of overbilling (e.g., for materials stored) are explicitly allowed. Sticking strictly to these terms is vital to avoiding legal risks.
Best Practice: Consult with a legal advisor to ensure that your billing practices align with the contract and state regulations.

Overbilling can be an effective tool for managing cash flow in construction, but it must be executed cautiously and in strict alignment with the contract terms.
