Unbilled receivables are amounts a business has earned by delivering goods or services but has not yet invoiced the customer for, so the revenue is recognised in the accounts before any bill has gone out. They sit on the balance sheet as an asset, representing money you are entitled to but have not formally requested. The moment you raise the invoice, the balance moves out of unbilled receivables and into ordinary accounts receivable.
They arise whenever work is done ahead of billing. Think of a consultancy part-way through a fixed-fee project, a SaaS business that has delivered a month of service it bills in arrears, or a contractor who has hit a milestone but invoices monthly. In each case the revenue has been earned, the accounting recognises it, but the paperwork to collect it has not yet been issued.

Suppose a consultancy delivers 10,000 of work in March under a contract it will not invoice until April. The revenue is earned in March, so under accrual accounting it must be recognised in March, even though no invoice exists yet. Here is how the entries flow.
March: recognise the earned revenue (no invoice yet)
| Account | Debit | Credit |
|---|---|---|
| Unbilled receivables (asset) | 10,000 | 0 |
| Revenue | 0 | 10,000 |
April: raise the invoice, reclassify to accounts receivable
| Account | Debit | Credit |
|---|---|---|
| Accounts receivable | 10,000 | 0 |
| Unbilled receivables (asset) | 0 | 10,000 |
Notice that revenue is recognised only once, in March, when it was earned. The April entry does not touch revenue at all; it simply moves the balance from one asset account to another now that a formal invoice exists. When the customer pays, a final entry clears accounts receivable and increases cash. This is accrual accounting doing its core job: matching revenue to the period it was earned in, rather than the period you happened to bill or get paid in.
Unbilled receivables and accrued revenue describe the same thing from two angles: accrued revenue is the income statement view of revenue earned but not yet billed, while unbilled receivables is the balance sheet asset that represents it. When you accrue revenue you have not invoiced, the credit lands in revenue and the matching debit is the unbilled receivable. They are two sides of one entry, which is why the terms are often used interchangeably. If there is a shade of difference in practice, it is emphasis: accountants reach for "accrued revenue" when talking about recognising the income, and "unbilled receivables" when talking about the asset sitting on the balance sheet waiting to be invoiced. Both point to work done but not yet billed.
The difference is the invoice: unbilled receivables are earned but not yet invoiced, while accounts receivable are earned and already invoiced, with a bill sent and payment now due. They are consecutive stages of the same money, moving from earned, to billed, to paid.
| Aspect | Unbilled receivables | Accounts receivable |
|---|---|---|
| Invoice status | Earned but not yet invoiced. | Earned and already invoiced. |
| Is money formally owed | No, the customer has not been billed. | Yes, a bill is sent and payment is due. |
| Can it be chased | No, there is nothing to chase yet. | Yes, it can be aged and collected. |
| Your priority | Invoice it promptly. | Follow up until it is paid. |
Revenue is earned and recorded as an unbilled receivable; you raise the invoice and it becomes a normal account receivable; the customer pays and it becomes cash. An unbilled receivable cannot be chased, because the customer owes nothing formally yet, so the priority is to invoice it promptly. Once it is in accounts receivable, the clock on your payment terms starts and it can be tracked, aged and collected like any other invoice through your receivables ledger.
Unbilled receivables are normal in any business that does work ahead of billing, but a growing pile of them is worth watching, because every unbilled balance is revenue you have earned but not yet asked to be paid for. The causes split cleanly into two groups: structural ones that are harmless, and operational ones that signal a problem.
Milestone or arrears billing built into the contract.
Monthly invoice runs that batch up the period's work.
Contracts that bill only on completion.
A slow or disorganised billing process.
Missing approvals holding the invoice up.
Finished work that sits unbilled because nobody raised the invoice.
That distinction matters because unbilled revenue is the very start of your cash cycle, and time spent here is pure delay: an invoice you raise two weeks late is paid two weeks late, on top of whatever your terms already allow. Left unmanaged, a large unbilled balance quietly lengthens your billing cycle and starves cash flow while the accounts still show healthy revenue. The fix is rarely complicated, it is speed: bill as soon as the work is done or the milestone is hit, so the balance converts to a real invoice and the payment clock actually starts.
Unbilled receivables sit under current assets on the balance sheet, separate from accounts receivable, because the two represent different stages of the same earned income. Keeping them in their own account matters for a clean read of your numbers: it shows reviewers how much revenue you have recognised that is genuinely invoiced and due, versus how much is still waiting to be billed. Lump the two together and you lose that signal, and your aged receivables report becomes misleading, because it would show balances that no customer has actually been asked to pay.
Accounting platforms like Xero and QuickBooks are built around the invoice as the trigger for accounts receivable, so they do not track unbilled revenue automatically. In practice teams handle it with a manual journal to an unbilled receivables or accrued revenue account at period end, then reverse it and raise the real invoice in the next period. The key discipline is consistency: recognise the unbilled balance the same way each period, and clear it promptly by invoicing, so the figure always reflects genuine work-in-progress rather than a billing backlog hiding in the accounts.
Controlling unbilled receivables comes down to shortening the gap between earning revenue and invoicing it. Converting unbilled revenue into cash is a two-step race: bill fast, then collect fast. Run through this checklist.
Track what is unbilledA balance nobody is watching is one nobody is clearing, so review it as deliberately as you review overdue invoices.
Set a tight billing rhythmBill on a predictable schedule so work does not sit waiting for an invoice run that is weeks away.
Tie invoicing to a clear triggerA delivered milestone, a closed period or a completed job, so nothing relies on someone remembering.
Make follow-up just as promptOnce an invoice is out, accounts receivable software chases it automatically the moment it is raised, so quick billing is not undone by slow collection.
The whole aim is to keep money moving from earned, to billed, to paid, with as little dead time as possible at each step.
