Deferred Revenue vs Unearned Revenue vs Deferred Income

Deferred revenue, unearned revenue and deferred income are the same thing. A customer has paid — or been invoiced — for goods or services you have not yet delivered, so the money is not income. It is an obligation to perform, and it sits on the balance sheet as a liability until you do.

If you only need one sentence, that is it. The rest of this page is why the three names exist and what to do with the balance.

Why three names

Term	Where it is used	Emphasis
Deferred revenue	US GAAP practice, SaaS metrics, investor reporting	The revenue is postponed
Unearned revenue	Textbooks and US-influenced writing	The revenue has not been earned
Deferred income	IFRS and EU statutory accounts, UK usage	Income of a future period

Some frameworks also say contract liability (IFRS 15), which is the technically precise term when the amount arises from a contract with a customer. In the Lithuanian chart of accounts the balance normally sits in ateinančių laikotarpių pajamos (income of future periods) or, where it is a prepayment against a specific order, in 4440 gauti išankstiniai apmokėjimai — advances received.

There is no accounting difference between the terms. Anyone who tells you deferred revenue and unearned revenue are distinct concepts is describing a house style, not a rule.

Why it is a liability

The instinct is that money received is income. It is not, because you still owe something.

A customer pays 2,400 € in January for twelve months of service. On 31 January you have delivered one month. If you recognized 2,400 € of revenue in January, you would be reporting eleven months of work you have not done, and if the customer cancelled in February you would owe most of it back. The obligation is real, which is what makes it a liability.

Account	Debit	Credit
2710 Bank	2,400
4440 Advances received / deferred income		2,400

Then, each month, 200 € of the obligation is discharged by delivering the service, and only then does it become revenue:

Account	Debit	Credit
4440 Advances received / deferred income	200
5001 Service revenue		200

Twelve of those entries retire the liability exactly as the year is delivered. This is the same deferral mechanic as prepaid expenses, pointed the other way — and the mirror image of accrued revenue, where the work comes first and the invoice second.

VAT does not wait. In most EU cases the VAT on a prepayment becomes due when the advance invoice is issued or the payment received, not when the service is delivered. So the deferred-income balance and the VAT liability move on different schedules, which is exactly why an advance invoice is a real document while a proforma is not.

Reading the balance

For a subscription business the deferred revenue balance is one of the more informative numbers on the balance sheet:

• It is a leading indicator. Deferred revenue rising faster than recognized revenue means bookings are outpacing delivery — growth that has been paid for but not yet reported.
• It is not cash. Some of it is; some was invoiced and never collected. Deferred revenue and bank balance are different questions.
• It is a real obligation. In an acquisition or a wind-down, the buyer or liquidator inherits the duty to deliver, which is why it is scrutinized in diligence.
• It distorts naive margin maths. Cash collected in January against costs incurred all year makes January look wonderful, which is precisely the illusion accrual accounting removes.

How Nordlet handles it

This is automated. Invoice lines carry a recognition method, and the revenue recognition engine builds a schedule for anything not recognized at a point in time — straight-line over a period, or on milestones. At issue the deferred portion is held rather than taken to revenue, and the engine releases each tranche on its scheduled date, posting the entries above.

Two details worth knowing. The release runs automatically when an accounting period is locked, so closing a month also recognizes everything earned in it — a period cannot be closed with revenue silently left unrecognized. And schedules are visible through POST /v1/sales/recognition-schedules/list, filterable by invoice, status and date, so the deferred balance is explainable line by line rather than being a single number someone has to defend.

Modifications — an upgrade or cancellation mid-term — adjust the remaining schedule rather than rewriting history, which keeps closed periods intact.

FAQ

Is deferred revenue the same as unearned revenue?

Yes — along with deferred income and, under IFRS 15, contract liability. They are different names for money received or invoiced for goods and services not yet delivered, recorded as a liability until delivery.

Is deferred revenue an asset or a liability?

A liability. You hold the customer's money but still owe them the goods or services, so the obligation is what appears on the balance sheet — not income.

When does deferred revenue become revenue?

As the performance obligation is satisfied — typically evenly over a subscription term, or at milestones for project work. Each release moves an amount from the liability to revenue.

Does deferred revenue affect VAT?

The VAT usually falls due earlier, when the advance invoice is issued or the prepayment is received, rather than when the service is delivered. So the VAT liability and the deferred-income balance move on different timelines.

Is deferred revenue the same as cash received?

Not necessarily. The balance can arise from an invoice that has not been paid, in which case there is a receivable and a deferred income balance at the same time — one saying the customer owes you, the other saying you owe the customer delivery.
