Unbilled Revenue: Definition, Journal Entries & Examples (2026)
Unbilled revenue is income you have earned but not yet invoiced. Under accrual accounting it belongs on your balance sheet today, not when the invoice goes out. Here is how to record it, how it differs from deferred and accrued revenue, and how to keep it from becoming a cash flow problem.
Unbilled revenue (also called accrued revenue or unbilled receivables) is income earned by delivering goods or services that has not yet been invoiced to the customer. Under accrual accounting, it is recognized when earned, not when billed. The journal entry is: debit Unbilled Receivables (asset), credit Revenue. When the invoice goes out, debit Accounts Receivable and credit Unbilled Receivables. Unbilled revenue sits as a current asset on the balance sheet. It is the opposite of deferred revenue, which is a liability representing cash received before work is done.
Key takeaways
- ✓ Unbilled revenue is earned income not yet invoiced. It is a current asset on the balance sheet under accrual accounting, not something to ignore until the invoice goes out.
- ✓ The journal entry is debit Unbilled Receivables, credit Revenue. When invoiced, debit Accounts Receivable and credit Unbilled Receivables.
- ✓ Unbilled revenue differs from deferred revenue: unbilled is work done but not yet billed (asset); deferred is cash received before work is done (liability).
- ✓ Under ASC 606, revenue is recognized when performance obligations are satisfied, regardless of when the invoice is issued. Unbilled revenue is the direct result of this timing.
- ✓ Unmanaged unbilled revenue creates cash flow gaps, distorts financial reporting, and increases the risk of revenue leakage from invoices that never get sent.
What Is Unbilled Revenue?
Unbilled revenue is income a business has earned by delivering goods or services but has not yet invoiced to the customer. The work is done. The obligation is met. The money is owed. But the invoice has not gone out yet.
This is not an edge case. It is a normal feature of accrual accounting for any business where service delivery and billing do not happen simultaneously. Consulting firms that bill at month-end for work completed throughout the month, construction companies that recognize revenue as project milestones are hit, SaaS businesses that deliver access continuously and bill in cycles, law firms that bill in arrears: all of them generate unbilled revenue routinely.
Under accrual accounting, the revenue belongs on your books when it is earned, not when the invoice goes out. That means unbilled revenue is not a bookkeeping lag to ignore. It is a real asset that needs to be recorded in the period it arises.
Common Names for the Same Concept
Unbilled revenue goes by several names depending on the industry and the accounting system: accrued revenue, unbilled receivables, unbilled accounts receivable (unbilled AR), and contract assets (the term used in ASC 606 contexts). They all refer to the same thing: earned income that has not yet been invoiced.
When Unbilled Revenue Arises
The most common situations that generate unbilled revenue are:
Arrears billing. A law firm completes 40 hours of work in March but sends the invoice at the beginning of April. March has unbilled revenue equal to 40 hours times the hourly rate.
Milestone-based projects. A consulting firm completes 60% of a fixed-price project by month-end but the contract only allows invoicing at 100% completion. The 60% of earned revenue is unbilled.
Recurring services with billing cycle gaps. A SaaS company delivers continuous access in December but the December billing cycle does not run until January 2. December has one day of unbilled revenue.
Work completed after billing cycles close. Any service completed after the billing run for the period creates unbilled revenue until the next billing cycle processes it.
Is Unbilled Revenue an Asset or a Liability?
Unbilled revenue is a current asset. It represents the legal right to collect payment for work already performed. That right exists whether or not the invoice has been issued. Under accrual accounting, the obligation from the customer was created when the service was delivered, not when the paperwork was sent.
It sits on the balance sheet alongside other current assets: cash, accounts receivable, and prepaid expenses. It is typically classified as current because the invoice is expected to be issued and collected within one year.
The key distinction to keep straight: unbilled revenue is an asset because the company has already performed. Deferred (unearned) revenue is a liability because the company has received payment but has not yet performed. The two are mirror images of each other in terms of timing and classification.
Unbilled Revenue Journal Entries
The journal entry process runs in two steps: initial recognition when the work is done, and reclassification when the invoice goes out.
Step 1: Recognize the Revenue When Earned
A consulting firm completes a $5,000 engagement in March. The invoice will not go out until April.
| Account | Debit | Credit |
|---|---|---|
| Unbilled Receivables | $5,000 | |
| Consulting Revenue | $5,000 |
To record March consulting revenue earned but not yet invoiced
Consulting Revenue hits the March income statement. Unbilled Receivables sits on the March 31 balance sheet as a current asset.
Step 2: Reclassify When the Invoice Goes Out
In April, the invoice is issued for $5,000.
| Account | Debit | Credit |
|---|---|---|
| Accounts Receivable | $5,000 | |
| Unbilled Receivables | $5,000 |
To reclassify unbilled receivable to accounts receivable upon invoice issuance
No additional revenue is recognized in April. The revenue was already captured in March. This entry simply moves the balance from Unbilled Receivables to Accounts Receivable, reflecting that the invoice now exists and the formal receivable has been established.
Step 3: Cash Collection
When the client pays in April or May:
| Account | Debit | Credit |
|---|---|---|
| Cash | $5,000 | |
| Accounts Receivable | $5,000 |
To record cash collection against the accounts receivable
Unbilled Revenue vs. Accrued Revenue
These two terms are effectively synonymous. Both describe earned income that has not yet been invoiced. "Accrued revenue" is the broader accounting term; "unbilled revenue" is the operational description of the same thing. You will see both used interchangeably in financial statements, accounting software, and industry literature.
The account on the balance sheet may be labeled "Accrued Revenue," "Unbilled Receivables," "Unbilled AR," or "Contract Assets" depending on the company's chart of accounts and whether they have adopted ASC 606 terminology. The underlying concept and accounting treatment are the same regardless of the label.
Unbilled Revenue vs. Deferred Revenue
These two are often confused but are fundamentally opposite in nature.
Unbilled revenue: Work is done. Cash has not arrived. The company has performed its obligation and is owed money. It is an asset.
Deferred revenue: Cash has arrived. Work is not done. The company has received payment and owes a future performance. It is a liability.
| Concept | Work Status | Cash Status | Balance Sheet |
|---|---|---|---|
| Unbilled Revenue | Done | Not received | Current asset |
| Accounts Receivable | Done and invoiced | Not received | Current asset |
| Deferred Revenue | Not yet done | Received | Current liability |
| Prepaid Expense (mirror) | Not yet received | Paid out | Current asset |
Unbilled Revenue vs. Unearned Revenue
Unearned revenue is another name for deferred revenue: cash received before performance. The company has an obligation to deliver. Until it does, that cash sits as a liability.
A client who pays $12,000 upfront for a year of consulting creates unearned revenue of $12,000 on day one. Each month that the consulting service is delivered, $1,000 moves from unearned revenue (liability) to revenue (income). By the end of the year, the liability is zero and all $12,000 has been recognized.
Unbilled revenue runs in the opposite direction: the service is delivered first, the liability to the company builds up, and the cash arrives later. There is no obligation left to fulfill; what remains is the right to be paid.
How Unbilled Revenue Affects Financial Statements
Balance Sheet
Unbilled revenue sits in current assets, typically labeled Unbilled Receivables or Accrued Revenue. It increases total current assets and by extension working capital. A growing unbilled receivable balance is not necessarily a problem, but it warrants attention: it means the gap between delivery and invoicing is widening. If that gap grows faster than revenue, it signals a billing process problem.
Income Statement
Unbilled revenue increases reported revenue in the period the service is delivered, not the period the invoice goes out. This is the matching principle doing its job: revenue is recognized in the same period as the costs that generated it. For companies that track gross margin by period, this matters. Recognizing revenue only when billed would systematically understate margin in delivery-heavy periods and overstate it in billing-heavy periods.
Cash Flow Statement
An increase in unbilled receivables appears as a use of cash in operating activities (working capital increases, cash decreases). This is one reason companies with fast-growing unbilled balances can report strong net income while simultaneously showing weak operating cash flow. The revenue is real; the cash just has not arrived yet. Understanding this distinction is essential for anyone analyzing a business's cash position separate from its profitability.
ASC 606 and Revenue Recognition
Under ASC 606 (the current U.S. GAAP revenue recognition standard), revenue is recognized when or as performance obligations are satisfied, regardless of when the invoice is issued or cash is received. This is the accounting standard that makes unbilled revenue both mandatory to record and potentially complex to calculate.
The Five-Step Model
ASC 606 requires running through five steps for every revenue contract:
Step 1: Identify the contract. A valid contract exists with defined terms, rights, and payment conditions.
Step 2: Identify the performance obligations. Each distinct good or service promised in the contract is a separate obligation. A software company selling both a license and implementation services has two obligations.
Step 3: Determine the transaction price. The total amount the company expects to receive, including variable consideration, discounts, and constrained estimates.
Step 4: Allocate the price to each obligation. If there are multiple obligations, the transaction price is allocated based on standalone selling prices.
Step 5: Recognize revenue when each obligation is satisfied. Revenue for each obligation is recognized at the point of transfer of control, or over time if the customer simultaneously receives and consumes the benefit.
Unbilled revenue arises naturally from Step 5: when a company satisfies an obligation before it can invoice (because of billing cycle timing, contract restrictions, or milestone structures), it records the earned revenue as unbilled receivables. Accruer automates the recurring journal entries that implement this recognition in QuickBooks Online, ensuring unbilled revenue posts in the right period without manual calculation.
Risks of Unmanaged Unbilled Revenue
Revenue Leakage
The most direct risk: invoices that never get sent. If unbilled revenue is not tracked in a dedicated account and reviewed regularly, it is entirely possible for earned income to fall through the cracks and never get billed. For a company doing $5M in annual revenue, even a 1% leakage rate is $50,000 in lost income per year.
Cash Flow Gaps
Unbilled revenue is an asset, but it is not cash. A company can report strong earnings while simultaneously running short on cash because the receivable cycle is long. This is particularly acute for project-based businesses where large amounts of work complete near period-end but billing does not go out for weeks.
Distorted Financial Reporting
Companies that do not record unbilled revenue properly understate assets, understate revenue, and understate net income in delivery-heavy periods. This distorts gross margin analysis, period-over-period comparisons, and any metric that relies on reported revenue being complete.
Client Disputes
The longer the gap between service delivery and invoicing, the harder it is for clients to connect the invoice to the work. Late billing increases disputes, delays, and write-offs. A client who receives an invoice four months after service delivery is more likely to question it than one who receives it at the end of the month the work was done.
Compliance Risk
Companies subject to audit under GAAP have a clear obligation to recognize revenue when earned. Systematically deferring revenue recognition to the billing date rather than the delivery date is a GAAP violation. For companies seeking financing, investor reporting, or acquisition due diligence, this creates real exposure.
How to Manage and Minimize Unbilled Revenue
Create a Dedicated Unbilled Receivables Account
The first step is visibility. Set up a dedicated Unbilled Receivables account in your chart of accounts, separate from Accounts Receivable. This makes it possible to see the unbilled balance at any time, track its trend month over month, and identify specific engagements or clients where billing is lagging.
Build a Monthly Close Routine Around It
Make unbilled revenue part of your standard month-end close checklist. At the close of each period, every engagement or project should be evaluated: has the revenue been earned? Has the invoice been issued? If yes to the first and no to the second, an unbilled receivable entry is required. This discipline prevents the balance from accumulating silently over multiple periods.
Tighten Billing Cycles
The most effective long-term solution is reducing the gap between service delivery and invoicing. This might mean moving from monthly to bi-weekly billing, automating invoice generation based on project completion triggers, or setting up contracts that allow interim billing at defined milestones rather than waiting for full completion.
Review the Unbilled Balance Weekly
A weekly review of the Unbilled Receivables aging catches stale balances before they become problems. Any unbilled item older than 30 days deserves a specific explanation: is the invoice in progress? Is there a billing hold? Is there a dispute? Aging unbilled receivables that do not have clear answers are a signal of process failure.
Automate Where Possible
Manual unbilled revenue tracking is error-prone. Tools like Accruer automate the recognition entries in QuickBooks Online so that revenue posts in the right period without relying on someone to remember to make the journal entry. This is especially valuable for companies with recurring service engagements where the same unbilled revenue pattern repeats every period.
Common mistakes
Recognizing revenue at invoice date instead of delivery date
This is the most common error and a GAAP violation. Revenue belongs in the period the service is performed or the goods are delivered, not the period the invoice goes out. Billing in arrears does not change the accounting. If work is done in March and invoiced in April, March takes the revenue and the unbilled receivable. April takes only the reclassification entry when the invoice is issued.
Lumping unbilled receivables into accounts receivable
Unbilled receivables and accounts receivable are different things. Accounts receivable represents invoiced amounts owed. Unbilled receivables represent earned but uninvoiced amounts. Mixing them makes it impossible to see how much revenue has been earned versus how much has been invoiced, obscures billing lag, and creates reconciliation problems when invoices eventually go out. Maintain separate accounts for each.
Not reviewing the unbilled balance at month-end
Unbilled revenue that is not reviewed monthly accumulates silently. Engagements complete, months pass, and the invoice never goes out because nobody was tracking the open balance. A standing month-end review of unbilled receivables aging is the process control that prevents revenue leakage. Without it, earned income can sit in the asset account indefinitely and eventually get written off as uncollectible.
Confusing unbilled revenue with deferred revenue
Unbilled revenue is an asset: work done, cash not yet received. Deferred revenue is a liability: cash received, work not yet done. Misclassifying one as the other produces a balance sheet that is wrong in both directions: assets are understated or overstated, and liabilities are misstated accordingly. The question to ask is always: has the work been performed? If yes, it is unbilled revenue (asset). If no, it is deferred revenue (liability).
Failing to account for unbilled revenue in cash flow analysis
A growing unbilled receivable balance increases reported revenue and net income while consuming cash. Companies that focus only on profitability metrics without tracking the unbilled balance can be surprised by cash shortfalls even in periods of strong reported performance. Cash flow from operations will show the working capital build as a use of cash. Understanding this linkage between unbilled revenue and operating cash flow is essential for accurate financial planning.
Stop recording unbilled revenue entries by hand every month
Accruer posts the unbilled revenue journal entry automatically in QuickBooks Online. Write the amount and the period, and it handles the recognition, the reclassification on invoice, and the period-end reversal. No missed periods, no manual spreadsheet, no GAAP exposure from late recognition.
See AccruerFrequently asked questions
What is unbilled revenue?
Unbilled revenue is income earned by delivering goods or services that has not yet been invoiced to the customer. Under accrual accounting it is recorded as a current asset (Unbilled Receivables) in the period the work is performed, not the period the invoice is issued. It is also called accrued revenue, unbilled AR, or unbilled receivables.
Is unbilled revenue an asset or a liability?
It is a current asset. The company has performed the service and has a legal right to collect payment. That right exists regardless of whether the invoice has been issued. Deferred (unearned) revenue is the opposite: cash received before performance, which creates a liability because the company still owes the work.
What is the journal entry for unbilled revenue?
When work is completed but not yet invoiced: debit Unbilled Receivables, credit Revenue. When the invoice is issued: debit Accounts Receivable, credit Unbilled Receivables. No additional revenue is recognized when the invoice goes out; the revenue was already captured in the period of delivery. Cash collection clears Accounts Receivable against Cash.
What is the difference between unbilled revenue and deferred revenue?
They are opposites. Unbilled revenue: work done, not yet invoiced, cash not received. It is an asset because the company is owed money. Deferred revenue: cash received, work not yet done. It is a liability because the company owes future performance. Both involve timing differences between cash and work, but in opposite directions.
Does unbilled revenue affect cash flow?
Yes. An increase in unbilled receivables appears as a use of cash in the operating section of the cash flow statement (working capital increases, cash decreases). This is why companies with fast-growing unbilled balances can report strong net income while showing weak operating cash flow. The revenue is real; the cash just has not arrived yet.
When does ASC 606 require recognizing unbilled revenue?
Under ASC 606, revenue is recognized when or as performance obligations are satisfied. If a company satisfies an obligation before it can issue an invoice (due to billing cycle timing, contract restrictions, or milestone structures), it recognizes the revenue immediately as an unbilled receivable. The invoice date is irrelevant to the recognition date under ASC 606.
What is the difference between unbilled revenue and accounts receivable?
Accounts receivable is invoiced revenue owed by customers. Unbilled revenue is earned but not yet invoiced. Both are current assets, but they represent different stages of the billing cycle. Unbilled receivables convert to accounts receivable when the invoice is issued. Maintaining them in separate accounts makes it possible to track billing lag and identify revenue recognition timing.
How do I reduce unbilled revenue in my business?
The most effective approaches are: create a dedicated Unbilled Receivables account so the balance is visible, build a month-end close routine that includes reviewing the unbilled aging, tighten billing cycles to reduce the gap between delivery and invoicing, set up milestone billing in contracts to allow invoicing before full project completion, and automate recognition entries so revenue posts in the right period without manual intervention.
