Underbillings
Underbillings represent revenue earned by a company for services or goods delivered that have not yet been formally billed to the client. This creates an asset on the balance sheet.
What is Underbillings?
Underbillings occur when a company has earned revenue for goods or services delivered but has not yet issued an invoice to the client. This situation frequently arises due to contractual terms, project milestones, or specific billing cycles. From an accounting perspective, underbillings represent an asset on the company’s balance sheet.
They are essentially unbilled receivables, reflecting work performed for which payment is due or will become due, even if the formal billing document has not been generated. Managing underbillings is crucial for accurate financial reporting and maintaining healthy working capital. Mismanagement can lead to cash flow issues or misrepresentations of a company’s financial health.
Underbillings refer to revenue that a company has earned by delivering goods or services but has not yet formally billed to the client, representing an asset on the balance sheet.
Key Takeaways
- Underbillings represent earned revenue that has not yet been invoiced.
- They are recorded as an asset, typically “Costs and Estimated Earnings in Excess of Billings,” on a company’s balance sheet.
- Common in long-term contracts, service industries, and project-based work.
- Effective management is vital for accurate revenue recognition, cash flow planning, and financial transparency.
- Differences between earned revenue and billed revenue create underbillings or overbillings.
Understanding Underbillings
Underbillings are a critical concept in accounting, particularly for businesses engaged in long-term contracts, service provision, or project-based work. They typically arise when revenue is recognized over time as work progresses, but the contractual billing schedule dictates invoicing at specific milestones or intervals. For instance, a construction company might incur costs and complete a portion of a project, thereby earning revenue, before it’s contractually permitted to send an invoice. This accounting entry ensures that financial statements accurately reflect the economic activity and earnings of the company, even when billing cycles lag behind service delivery. Properly identifying and accounting for underbillings is essential for maintaining accurate financial records.
Formula
The concept of underbillings can be understood through a comparative relationship rather than a strict mathematical formula. It generally represents the amount where:
Revenue Earned (Recognized) > Amount Billed to Client
For project-based accounting, specifically, it can be conceptualized as:
Underbillings = Total Costs Incurred + Recognized Profit - Total Billings to Date
This calculation highlights the extent to which a company’s recognized earnings on a project exceed the invoices sent to the client. The resulting positive figure signifies an asset that will be converted into a receivable upon future billing.
Real-World Example
Consider a software development firm that enters a contract to build a custom application for $500,000. The contract stipulates monthly progress billing for 80% of completed work, with the remaining 20% billed upon final delivery. In the first month, the firm completes 20% of the project, incurring costs and recognizing $100,000 in revenue based on completion.
However, the billing terms dictate an invoice only after the first major module is complete, which is scheduled for the second month. As of the end of the first month, the firm has earned $100,000 but has billed $0. This $100,000 represents underbillings. It is recorded as an asset on the balance sheet, reflecting the firm’s right to bill for this earned revenue in the future.
Importance in Business or Economics
Underbillings have significant implications for a business’s financial health and reporting. They directly affect working capital management because until an invoice is sent and paid, the earned revenue is not yet converted into cash. High levels of underbillings can strain a company’s funding requirement and liquidity, necessitating careful cash flow forecasting. This also relates to overall efficiency performance in the billing process.
From an economic perspective, underbillings contribute to the accuracy of industry-specific economic indicators. They ensure that the reported revenues reflect the actual economic activity performed, rather than just the timing of invoicing. This distinction is crucial for investors, creditors, and stakeholders to assess a company’s true operational performance and value, impacting business investor relations. Adhering to a robust operations manual for billing and project management can minimize discrepancies and improve capacity management.
Types or Variations
While “underbillings” is a specific term, related concepts often describe similar financial scenarios. One common variation arises from differing revenue recognition methods versus billing schedules. For instance, percentage-of-completion accounting often generates underbillings or overbillings depending on the phase of the project. Retainage agreements, where a portion of payment is withheld until project completion, can also contribute to underbillings.
Another related concept is accrued revenue, which is revenue earned but not yet collected, which often encompasses underbillings. The distinction typically lies in the contractual context; underbillings specifically refer to situations where the right to bill exists but the invoice has not been issued. Conversely, overbillings occur when a company bills a client more than the revenue it has actually earned.

Frequently Asked Questions (FAQs)
What is the difference between underbillings and accrued revenue?
Accrued revenue is a broader term for revenue earned but not yet collected, which can include underbillings. Underbillings specifically refer to situations where revenue has been earned, but the formal invoice has not yet been issued, often due to contractual billing schedules or project milestones. All underbillings are a form of accrued revenue, but not all accrued revenue are underbillings (e.g., interest earned but not yet paid or invoiced is accrued revenue but not underbilled in the typical project context).
How do underbillings affect a company’s financial statements?
Underbillings are reported as a current asset on the balance sheet, typically under an account like “Costs and Estimated Earnings in Excess of Billings” or “Unbilled Revenue.” They represent an amount expected to be converted into a receivable once billed. On the income statement, the corresponding revenue is recognized as earned, even if not yet billed, ensuring accurate reflection of profitability.
Why do companies have underbillings, and how can they be managed?
Companies have underbillings primarily due to timing differences between when revenue is earned (work performed) and when it can be contractually billed. This is common in long-term contracts with milestone-based billing. To manage underbillings, companies should implement robust project tracking systems, align billing cycles with revenue recognition policies, and ensure timely invoice generation upon meeting contractual milestones. Regular review of work-in-progress and client contracts helps identify and address potential billing delays.
