Deferred revenue: why an annual prepayment isn’t revenue yet

01Billed, collected, earned#

Three things happen to a subscription contract, usually at three different times. You bill it: an invoice, and a receivable until it’s paid. You collect it: cash. And you earn it, a little each day, by providing the service. Under US GAAP revenue follows the third, not the first two. ASC 606 recognizes revenue as you satisfy your obligation to the customer, which for a subscription means ratably across the service period.

On the day the annual invoice goes out, the journal entry is a debit to accounts receivable and a credit to deferred revenue, both $12,000. Each month after, $1,000 moves from deferred revenue to revenue. At the end of the year the deferred balance is zero and the whole contract has been recognized, one month at a time.

Check it at any date: on March 31 three months are earned, so revenue to date is $3,000 and $9,000 is still deferred. When the cash arrives the receivable is cleared, debit cash, credit accounts receivable, and revenue doesn’t move at all. And when a contract doesn’t divide evenly, the last month absorbs the rounding: a $10,000 annual plan releases $833.33 for eleven months, $9,166.63 in all, and $833.37 in the twelfth, so the schedule ends at exactly zero.

02Why it sits with the liabilities#

Deferred revenue is a liability because that’s what it is: if you stopped providing the service tomorrow, you’d owe most of that money back. ASC 606 calls it a contract liability. The opposite case, service delivered but not yet billed, is a contract asset or an unbilled receivable.

A deferred balance that grows quarter over quarter is usually good news: customers are paying you in advance for more and more future service. A balance nobody can explain is not. The fix is a schedule behind it that lists, for every open contract:

• Each contract’s start date, end date and total value.
• The amount recognized each month, with the final month absorbing any rounding.
• The closing balance, tied every month to the deferred revenue line on the balance sheet.
• Anything due to be earned more than twelve months out, split out as non-current.

03Where it goes wrong#

The most common mistake is booking the whole invoice as revenue in the month it’s paid. That month looks excellent, the next eleven look flat, and revenue stops agreeing with ARR. The second is treating billings, cash and revenue as one figure in a board deck. The third is a mid-term change, an upgrade, a downgrade or a refund, handled by editing the original entry instead of booking the change in the month it happens.

Setup fees, usage charges and multi-year deals each need a policy decision. Write it down once, apply it the same way every month, and the schedule does the rest.
