Unbilled revenue is an accounting asset representing revenue recognized for goods or services already provided when the business does not yet have an unconditional right to invoice the customer. The exact recognition and presentation depend on the contract and applicable accounting policy.
How is unbilled revenue calculated?
A practical contract-level roll-forward is closing unbilled revenue = opening unbilled revenue + revenue recognized before billing − amounts newly invoiced from that balance ± approved adjustments.
Illustrative unbilled-revenue roll-forward
| Calculation step | Amount | Explanation |
|---|---|---|
| Opening unbilled revenue | $30,000 | Prior-period balance |
| Revenue recognized before billing | $45,000 | Performance recognized this period |
| Amount invoiced | ($50,000) | Previously unbilled value moved to receivable |
| Closing unbilled revenue | $25,000 | $30,000 + $45,000 − $50,000 |
The illustrative $25,000 is not cash and is not automatically an overdue receivable. It remains subject to the company’s recognition policy and contract evidence.
Unbilled revenue versus accounts receivable
Accounts receivable usually reflects an unconditional right to consideration after invoicing or when only time is required. Unbilled revenue remains conditional on another event or billing milestone.
What evidence supports the balance?
Link the contract, performance obligation, milestone or usage evidence, recognition calculation, billing schedule, approvals and subsequent invoice.
What risks should be reviewed?
Unsupported completion estimates, delayed billing, contract changes, disputes and duplicate recognition can overstate the asset. Reconcile balances to subsequent invoices and investigate aging.
