Which balance sheet classification best describes unbilled receivables?

• A. Liability
• B. Asset
• C. Equity
• D. Revenue

Answer: (B)

Unbilled receivables are earned revenue that hasn’t yet been billed to the customer. In construction accounting, revenue is often recognized as the work progresses (percent‑of‑completion), which creates a right to collect cash even before an invoice goes out. That right to cash is an asset on the balance sheet, usually shown as a current asset or as “unbilled revenue” within receivables.

For example, if you recognize $100,000 of revenue for work completed this period but haven’t billed the client yet, you would debit unbilled receivable and credit revenue. When you later issue the invoice, you reclassify that amount from unbilled receivable to accounts receivable.

So, unbilled receivables best fit an asset because they represent an expected future cash inflow you’ve earned, not an obligation (liability), nor ownership (equity) or income (revenue) at the moment of recognition.
