Contract assets versus unbilled receivables
Unbilled revenue can sit in receivables or contract assets. The test is whether payment waits only on invoicing and time, and it shapes how you collect.
Treat an unbilled balance as a receivable only when nothing stands between you and payment except invoicing and the passage of time. If payment depends on a milestone or another condition, treat it as a contract asset. Collecting it is then project work, not dunning work. Settle the label per contract type before you design collection or reporting. This rests on a comment-letter response filed with the SEC about unbilled receivables and on revenue notes in interim filings for 2020.
Why does our unbilled balance carry two different names?
Most finance teams carry revenue that is recognized but not yet invoiced. Some call it unbilled receivables, some call it contract assets. The label decides which line it sits on, who is asked to collect it and what an outside reviewer will question. In a comment letter, SEC staff asked a company to clarify whether its unbilled receivables were contract assets as defined in ASC 606-10-20. The alternative was receivables due unconditionally for services already rendered except for physical invoicing and the passage of time. Staff also asked how removing $18,434,000 of contract assets from a table was appropriate, since that amount appeared necessary to tie to total accounts receivable, net on the balance sheet.
What decides the label?
The company answered that its unbilled receivables are receivables, because they are due unconditionally for services already rendered except for physical invoicing and the passage of time. It said it had revisited the definition and believed it had no assets that satisfy it. It kept the $18,434,000 in the table and changed the name from contract assets to unbilled receivables. The same response revised its remaining performance obligations: the $34.7 million at March 31, 2019 had been calculated as all remaining potentially billable amounts under existing fixed rate contracts. After reassessment, it amounted to $16.9 million of consideration received or invoiced for per claim or fixed fee services not yet rendered.
A filing for the three months ended March 31, 2020, from a company reporting testing, repair and maintenance services, draws the same line. Its trade accounts receivable include billed and unbilled amounts currently due and represent unconditional rights to receive consideration. Its contract assets include unbilled amounts typically from fixed-price contracts under the cost-to-cost method, where revenue recognized exceeds the amount billed and the right to payment is conditional on something other than the passage of time.
Where does each label show up?
In that 2020 filing, contract assets sit in the Prepaid expenses and other current assets line. A filing for the six months ended June 30, 2020 describes contract assets typically from retail wireless contracts with a multiyear service period and a promotional discount. It reports $2,217 thousand current, in prepayments and other current assets, and $651 thousand noncurrent, in other assets.
This means the same unbilled amount is either collectible once an invoice goes out, or only after a condition is met. Unbilled receivables are a billing backlog. Contract assets wait on progress or a milestone, so the owner is usually the project or contract manager. Fixed-price, milestone-billed work at EPC and engineering firms tends to produce the second kind.
Which label fits your unbilled balances?
The decision is which contract types produce receivables, which produce contract assets, and who works each.
| Option | We would choose it when | What we would check first |
|---|---|---|
| Unbilled receivable | Only invoicing and time stand before payment | Invoicing trigger per contract, age of unbilled items |
| Contract asset | Payment waits on a milestone or other condition | Which condition, who confirms it, current or noncurrent |
| Split by contract type | Time and materials and fixed-price work run side by side | Revenue method per contract, mapping to balance sheet lines |
| Rename, keep the balance | The amount ties to accounts receivable, net | That the definition supports it, as in the SEC response |
What to do this quarter
- Pull the unbilled balance by contract and tag each item: waiting on an invoice, or waiting on a condition.
- Name one owner per tag: billing for invoice-ready items, project controls for milestone items.
- Measure days from service rendered to invoice for unbilled receivables, separately from DSO.
- Check where billing triggers are captured at order entry, because the label starts there; see quote-to-order.
- Reconcile the labels in your notes with the balance sheet lines they tie to.
What this means for a bottleneck worth $1M or more
If unbilled items pile up because invoices wait on manual checks, milestone confirmations or missing contract data, the work spans billing, projects and collections. That is one domain to redesign, not a reporting fix. We would use rules for the predictable, AI for the messy, such as reading contracts and progress evidence to propose a label, and people for consequential decisions: classification, write-off, credit hold. AI never decides alone. This sits in customer-to-cash.
Limits of this evidence
These filings show how the filers described and classified unbilled balances, and one SEC staff challenge. They do not show how often staff raises this question. They show no collection results, aging or DSO for either label. They cover services and wireless contracts, not other industries or contract types. They are not a benchmark for unbilled balance size and not accounting advice for your contracts.
Questions buyers ask
Is an unbilled receivable the same as a contract asset?
Not in the filings discussed here. An unbilled receivable is due unconditionally except for invoicing and the passage of time, while a contract asset's right to payment is conditional on something other than the passage of time.
Where do contract assets appear on the balance sheet?
A filing for the three months ended March 31, 2020 included contract assets in the Prepaid expenses and other current assets line. A filing for the six months ended June 30, 2020 put the current portion in prepayments and other current assets and the noncurrent portion in other assets.
Does the label change collection work?
In our view, yes. An invoice-ready receivable needs a bill sent, while a contract asset needs its condition met first, usually by the project or contract owner.
