Unbilled Revenue

Unbilled revenue is revenue recognised for goods or services transferred to a customer before an invoice is sent. Under IFRS 15, the related right may be a contract asset or a receivable, depending on whether it is conditional on more than time.

It is not the same as cash earned.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

An engineering firm completes work in March but issues its invoice in April, and if the work satisfies the revenue recognition requirements in March, the firm may record revenue then even though it has not sent a bill. The corresponding balance is a right to consideration, not cash in the bank.

Under IFRS 15, revenue is recognised when or as a performance obligation is satisfied by transferring control of a promised good or service, so work performed does not automatically mean all contract revenue has been earned, and the agreement and the measure of progress need checking. The balance sheet label depends on the right.

IFRS 15 describes a contract asset when the right to consideration for transferred goods or services remains conditional on something other than time, while an unconditional right is shown separately as a receivable. That distinction is easy to miss: a bill that has not yet been prepared may still be a receivable if only time must pass before payment is due, and conversely, sending a document called an invoice does not eliminate a substantive contractual condition.

Start with the contract: identify what the customer was promised, when it receives the benefit and how the transaction price is allocated, then compare recognised revenue with the amount already billed or due. 'Revenue earned minus amount invoiced' is a planning shortcut, not a complete IFRS formula, because advance invoices, contract liabilities, modifications and conditional rights can make the simple subtraction misleading.

For a straightforward illustration, suppose $500,000 of revenue has been recognised and $380,000 has been billed for that same work, so a remaining $120,000 may be unbilled, although its proper balance sheet presentation still depends on the contractual right. Do not recognise every hour logged as revenue, since a fixed-price project may require an appropriate progress measure and estimates of total work, while a time-and-materials contract may have different evidence for completed services and enforceable payment.

Milestone billing can lag work performed, as a contract might permit an invoice only after customer acceptance even though some revenue is recognised over time. Determine whether the acceptance condition is substantive before classifying the asset.

Keep a contract-by-contract schedule showing opening balance, revenue recognised, invoices, cash collections, adjustments and closing balance, and reconcile it to the general ledger, because a single unexplained total makes errors difficult to find. Support the estimate with evidence such as approved work records, delivery confirmations, milestones or reliable progress data; invoices issued after period-end may help check an earlier estimate but do not replace evidence of performance at the reporting date.

Review aged balances too, since a long-outstanding contract asset may reflect unresolved acceptance, disputed scope or a weak progress estimate, and ageing by project and reason is more useful than treating all old amounts as a billing-team problem. A timely billing process can reduce the time between performance and an invoice where the contract allows it, but it cannot create an unconditional right sooner than the contract permits.

Cash flow can remain strained while reported revenue grows, because wages and supplier bills may be paid before the customer owes cash, so forecast invoice eligibility, due date and actual collection separately, and remember that IFRS 15 requires assessment of a contract asset for impairment under IFRS 9. For owners, unbilled revenue shows a gap between accounting performance and customer billing, so understand why that gap exists, which rights are conditional and when the business can actually invoice and collect.

In practice

Real-world examples.

1

Example

A consultancy completes $60,000 of work in March that is eligible for revenue recognition but bills in April. March revenue includes the $60,000 and the balance sheet carries an unbilled amount at the month-end. The April invoice then moves it into billed receivables.

2

Example

A utility estimates delivered service through month-end before reading every meter. It recognises revenue for the estimated usage and records the unbilled amount, then adjusts when the meter readings and bills are issued.

3

Example

A contract asset remains conditional on customer acceptance of another stage. The firm keeps it separate from receivables and reports it as a contract asset until acceptance removes the condition.

Formula

Calculation

Illustrative same-contract gap = recognised revenue for transferred work minus related amounts billed. $500,000 - $380,000 = $120,000; classification depends on the right. Worked classification: suppose $50,000 of the $120,000 can be invoiced only after the customer accepts a later stage, so the right is conditional on more than time, while the other $70,000 needs only the passage of time before it is due. The $50,000 is a contract asset and the $70,000 is a receivable, and $50,000 + $70,000 = $120,000 reconciles to the gap.

Case study

Seen in the real world.

This entirely fictional example follows Sandstone Engineering, an invented firm whose month-end unbilled balance kept growing. It reconciled each project to contract milestones and found a mix of delayed invoices and conditional acceptance rights. The firm sped up invoices where permitted and tracked acceptance separately. It did not assume every unbilled balance was immediately collectible.

Watch out

Common mistakes.

  • Recording all work in progress as revenue without checking performance obligations.
  • Calling every unbilled amount a contract asset rather than checking whether the right is unconditional.
  • Assuming recognised revenue will become cash as soon as an invoice is created.
