Unearned Revenue: What It Is and When It Becomes Income
Sam's List Editorial | 2026-10-05
Unearned revenue is money you have collected for work you have not done yet. It feels like income because it landed in your bank account. On your books, it is a debt to your customer: you owe them the work or the money back.
That gap trips up owners who take deposits, annual prepayments or retainers. Two Sam's List firms sit at the two ends of it. Legal Ease Bookkeeping does law firm bookkeeping, where retainers and trust accounting make unearned fees a daily issue. System Six serves growing small businesses with $1 million to $10 million in revenue that need a monthly close and fractional CFO support. This is an explainer, not a ranking. Every firm named is a vetted Sam's List member. The firms written up below are paid featured members of Sam's List.
What Is Unearned Revenue?
Unearned revenue is cash received before you deliver the goods or service. Under accrual accounting it is recorded as a liability when the cash arrives, not as revenue. Companies that report under US GAAP generally call it a contract liability under ASC 606, the revenue standard. This piece stays at the plain-English level.
The liability shrinks as you deliver. When the work is done, you move that amount out of the liability and into revenue.
The limitation: this describes accrual accounting. A business on the cash method generally counts money as income when it is received, so the same prepayment can look different. Which method you use is a question for your CPA.
Revenue Recognition Timing: When Does Cash Become Income?
Revenue recognition timing follows delivery, not payment. If you sell a six-month service and collect the full price on day one, the revenue is generally earned as you perform the service across those six months. If you ship a product, it is generally earned when the customer receives it.
A simple rule of thumb: ask what the customer paid for, and when you finished it. The date you finished is the date you have earned it.
Two things make this harder than it sounds. Some contracts bundle several promises, such as software plus setup plus support, and each may be earned on a different schedule. And some work is delivered at one moment, while other work is delivered steadily over time.
The limitation: GAAP revenue recognition has detailed rules, and a small business that does not issue GAAP statements may use a simpler, consistent method. Ask your accountant which standard applies to you and to any lender or investor who reads your numbers.
An Illustrative Example: $6,000 Received Up Front
Say a company collects $6,000 on January 1 for six months of service, to be recognized at $1,000 per month. The table below is illustrative only, using simplified entries.
| Date | Entry | Debit | Credit |
|---|---|---|---|
| Jan 1 | Cash | $6,000 | |
| Jan 1 | Unearned revenue (liability) | $6,000 | |
| Jan 31 | Unearned revenue | $1,000 | |
| Jan 31 | Service revenue | $1,000 |
The January 31 entry repeats at the end of each month through June. After three months, $3,000 has moved to revenue and $3,000 remains as a liability. After month six, the liability is zero and $6,000 of revenue has been recognized.
The limitation: real entries involve sales tax, refunds, discounts and contract terms. If the customer can cancel and get money back, the picture changes, so do not copy this table without checking the contract.
Unearned Fees and Retainers in a Law Firm
Law firms have the sharpest version of this problem. Unearned fees and retainers are advance payments from clients for legal work not yet done, and in many states an advance fee belongs to the client until the lawyer earns it. It is generally held in a client trust account, kept apart from the firm's operating money.
That means the cash is not the firm's to spend when it arrives. The bookkeeper tracks it by client and matter, shows the trust balance and the amount owed to each client, and moves money to operating only as fees are earned, usually when the invoice is issued or the work is billed.
Mix these up and the problems are real: spending client money, a trust balance that does not reconcile, or a month-end report that treats a retainer as profit.
Legal Ease Bookkeeping is based in Fort Worth, Texas, was founded in 2016, has 12 employees and works with law firms nationwide. Its profile lists law firm bookkeeping as its specialty and a $500,000 revenue minimum.
Legal Ease has 9 verified client reviews on Sam's List as of 2026-10-02. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences and do not represent an endorsement by Sam's List. Legal Ease is a paid featured member of Sam's List. Ratings and rankings are not indicative of future performance or results.
The limitation: trust accounting rules vary by state bar, and a bookkeeper does not give legal or ethics advice. Check your state's rules and ask ethics counsel what applies to your firm. The $500,000 minimum also puts smaller practices outside its range.
Unearned Revenue in a Growing Company
Outside law, the same pattern shows up in annual software plans, memberships, customer deposits, tuition, maintenance contracts and multi-month projects billed up front. The cash is real and helps your balance, but part of it is an obligation to deliver.
The practical risk is confusing cash with profit. A company that collects a large annual prepayment in December can look strong on the bank balance and thin on earned revenue. If you plan hires or spending from the bank balance alone, you may be spending next year's work before you have done it.
A monthly close handles this: someone tracks what was billed, what was delivered and what is still owed, and releases the liability on a schedule. A forecast built on that picture shows cash and earned revenue separately.
System Six is a Seattle firm founded in 2009, with about 41 employees, offering bookkeeping and fractional CFO work to small businesses with $1 million to $10 million in revenue. Its profile lists monthly fixed fees from $800 per month. The profile also says it helps organizations modernizing a finance function after an acquisition.
System Six has very few reviews on its profile, so we do not cite a count. Judge it on its stated specialty, tenure and team size, and ask for references.
The limitation: System Six lists a $1 million revenue minimum, so earlier-stage companies fall outside its range. A firm that does both the books and the planning also reviews its own work, so ask who checks the schedule of deferred amounts. Whether unearned revenue handling is in scope is something to confirm in writing.
Tax Timing Can Differ From Book Timing
Your books and your tax return do not always agree on when prepaid money counts. In some cases, rules for advance payments, such as IRC Section 451(c), let certain accrual-method taxpayers defer part of an advance payment to the following tax year. In other cases, the money is taxable when received.
Do not assume the tax answer matches the book answer, in either direction. This is the sort of detail that decides whether a December prepayment creates a tax bill in the current year.
The limitation: whether a deferral is available depends on your accounting method, the type of payment and how the contract is written. Ask a CPA before you rely on it.
Comparing the Two Situations
The two firms in this piece appear to fit different problems, based on their public profiles. Fit is our reading, not a promise.
| Legal Ease Bookkeeping | System Six | |
|---|---|---|
| Fits | Law firm bookkeeping, where retainers and trust accounting are daily work | Small businesses with $1M to $10M revenue needing monthly close and fractional CFO support |
| Unearned revenue question | Whose money is it, and has it been earned? | How much cash is really earned revenue? |
| Location | Fort Worth, Texas | Seattle, Washington |
| Stated minimum | $500,000 revenue | $1M+ revenue |
If you run a law firm, start with trust accounting and your state's rules. If you run a growing company with prepayments, start with a clean monthly close. You can browse fractional CFOs on Sam's List to compare more options. This piece is not a ranking. It describes each firm from its public profile, and no firm is placed above another.
Frequently Asked Questions
Is unearned revenue an asset or a liability?
It is a liability. The cash you receive is an asset, but the obligation to deliver work or return the money is a liability of equal size. As you deliver, the liability decreases and revenue increases. Some small businesses on the cash method do not record it this way, so confirm your method with a CPA.
When does unearned revenue become income?
Generally when you deliver the goods or perform the service, under accrual accounting. A six-month contract paid up front is typically recognized over the six months. Contracts with several parts may follow different schedules. Tax timing can differ from book timing, so ask a CPA about your situation.
Are law firm retainers unearned revenue?
Often they are treated as unearned fees until the lawyer earns them. In many states an advance fee is client money held in a trust account until earned. Rules vary by state bar, so check your state's rules and ask ethics counsel before deciding how to record and move the money.
Can I defer tax on money received in advance?
In some cases. IRC Section 451(c) lets certain accrual-method taxpayers defer part of an advance payment by one year, but eligibility depends on your method, the type of payment and your contract. Do not assume it applies. Ask a CPA before relying on a deferral.
