Deferred Revenue
Last Updated: October 5, 2026Deferred revenue is money you have collected for work you have not yet done, and it is a liability rather than income. It is the single most common place subscription, service and project businesses overstate their performance — because the cash is in the bank and it feels like a sale.
Why It Is a Liability
If a customer pays twelve months up front, you are holding their money and you owe them a year of service. Until that service is delivered, the money is an obligation. Revenue is earned as the obligation is discharged.
Recognising it all on receipt overstates the month it arrived and understates every month after. In a business with annual billing that distortion is severe: a strong month may simply be a renewal month, and growth becomes unreadable because the figures move with billing cycles rather than with the business.
It also creates a specific risk when the customer leaves. If someone cancels in month three of a twelve-month term with a refund due, revenue you already recognised has to come back out — and that reversal lands in a different period from the original overstatement.
Where It Shows Up
Subscriptions and retainers billed in advance.
Annual maintenance or service agreements — common in trades, where a membership plan is sold up front and delivered across a year.
Customer deposits on work not yet started. A deposit is the simplest form of deferred revenue and the most frequently misrecorded.
Gift cards and prepaid packages, where revenue is earned on redemption rather than sale.
Sponsorship and advertising paid before the content runs.
What Goes Wrong
Never recorded. Cash accounting in disguise.
Recorded and never released. The balance grows and nobody can explain it. Usually because the monthly release entry was set up once and then stopped.
Not unwound on cancellation. Refunds and mid-term churn have to reverse the unearned portion, or the balance accumulates a residue that never clears.
Not split between current and long term. Multi-year contracts have a portion earned beyond twelve months, and a reviewer will expect to see that split.
Confused with accrued revenue. They are opposites: deferred revenue is paid and not earned; accrued revenue is earned and not yet billed.
Deferred Revenue FAQs
Is a customer deposit revenue?
No. A deposit is money received for work not yet performed, which makes it a liability until the work is done. It is the simplest form of deferred revenue and the most commonly misrecorded — and in any business with lead times it affects every month end.
Why does our deferred revenue balance keep growing?
Usually one of two things: the monthly release entry stopped being made, or cancellations and refunds were never unwound against the balance. A credit against a partly-earned subscription reduces deferred revenue as well as current revenue; posting it all to the current month leaves a residue that never clears.
