Deferred revenue is cash a SaaS business has collected for software access it has not yet delivered. You record it as a liability when the money arrives and release it to revenue month by month as the subscription period passes. In Ireland there are two further things to get right: the revenue recognition rules in your financial reporting framework, and the VAT point in time, which does not always follow your accounting entries.
This guide explains the mechanics with a worked example, covers the 2026 changes to FRS 102, and shows where VAT and management reporting catch founders out.
TL;DR
- Deferred revenue (also called unearned revenue) is a current liability, not income, until you have delivered the service.
- An annual plan paid upfront is booked to deferred revenue, then released in equal monthly instalments for a typical subscription.
- For accounting periods beginning on or after 1 January 2026, most FRS 102 amendments apply, including a new revenue section built on a five-step model.
- VAT can fall due on payment in advance, even though the revenue is still deferred in your books.
- Bundles of software plus onboarding or training need to be split into separate obligations, each with its own timing.

What deferred revenue means for a subscription business
A SaaS company usually gets paid before, or at the same time as, it delivers. A customer pays €2,400 on 1 January for twelve months of access. On 1 January you have the cash, but you have earned nothing yet. You owe the customer a year of service. That obligation sits on the balance sheet as deferred revenue.
The reason it is a current liability is that the obligation is normally settled within twelve months or the normal operating cycle, as the CPA Ireland technical article explains. Multi-year prepayments are the exception: the part covering more than twelve months should be shown as non-current.
Two points trip up first-time founders:
- Cash is not revenue. A strong month of annual renewals lifts your bank balance and your liability, not your profit and loss account.
- Growth makes the liability bigger. The more upfront annual contracts you sign, the larger the deferred revenue balance. That is a sign of healthy demand, but it also means you carry an obligation to keep delivering.
Deferred revenue versus related terms
Readers often search for the difference between a few neighbouring concepts. In practice:
| Term | What it is | Where it sits |
|---|---|---|
| Deferred revenue | Cash received (or billed) for service not yet delivered | Liability on the balance sheet |
| Service revenue | The portion of the subscription already earned | Profit and loss account |
| Customer advance or deposit | Money received before delivery, often less structured, with no defined service period | Liability until earned |
| Accounts receivable | Amounts invoiced but not yet paid | Asset on the balance sheet |
| Accrued income | Work delivered but not yet invoiced | Asset on the balance sheet |
Deferred revenue and customer advances both represent an obligation to provide future value, and neither belongs in income until earned. The practical difference is that a SaaS subscription has a known service period, so the release schedule is easy to build.
The journal entries, step by step
The double entry is simple. When cash is received in advance, debit cash and credit deferred revenue. As the service is delivered, debit deferred revenue and credit revenue.
A worked example: one annual plan
Take a customer who pays €2,400 (excluding VAT) on 1 January for a twelve-month plan.
| Date | Entry | Debit | Credit |
|---|---|---|---|
| 1 Jan | Cash received for the annual plan | Bank €2,400 | Deferred revenue €2,400 |
| 31 Jan | Release one month | Deferred revenue €200 | Revenue €200 |
| 28 Feb | Release one month | Deferred revenue €200 | Revenue €200 |
| 31 Mar | Release one month | Deferred revenue €200 | Revenue €200 |
At 31 March you have recognised €600 of revenue and still carry €1,800 of deferred revenue. At 31 December the balance is nil and the full €2,400 has passed through the profit and loss account.
If your year end is 30 June, the same contract would show €1,200 of deferred revenue on that balance sheet (six months still to deliver), and that is the number your accountant, your investors and, eventually, a buyer will look at.
Monthly billing is simpler, but not free of adjustments
If you bill monthly in advance, the balance stays small, but you still need to defer any invoice that straddles a period end. A subscription invoiced on 20 June for the period 20 June to 19 July needs part of that invoice carried into July. Month-end cut-off matters even when the plans are small.
Credit notes, refunds and mid-term upgrades
Most real SaaS ledgers are messier than the example above:
- Upgrades: a customer moves from a €200 plan to a €350 plan halfway through. Release the old plan up to the change date, then start a new schedule for the remaining term.
- Refunds and cancellations: reduce the remaining deferred revenue and the cash or receivable, and keep a record of why.
- Free trials and discounts: a discount or free period changes the amount allocated to each month, so the schedule should be built from the contract, not from the invoice alone.
- Unpaid invoices: if you invoice an annual plan but have not been paid, you may book a receivable against deferred revenue. Your balance sheet grows on both sides, but no cash has arrived, which matters for cash flow forecasts.
What changes in 2026: FRS 102 and the new revenue section
Most Irish private SaaS companies report under FRS 102 rather than full IFRS. In March 2024 the FRC published its second periodic review, and most of its amendments take effect for accounting periods beginning on or after 1 January 2026. For a company with a calendar year end, that means the 2026 accounts are the first set prepared under the new rules.
The key change for software businesses is the new Section 23, which introduces a single five-step model for revenue from contracts with customers, aligned in proportion with IFRS 15. In plain terms, the question moves from what type of contract you have to what you have promised the customer.
The five steps, in practical form:
- Identify the contract with the customer.
- Identify the separate promises (performance obligations) in it.
- Determine the transaction price.
- Allocate that price across the promises.
- Recognise revenue as, or when, each promise is satisfied.
Where bundles bite
A plain monthly subscription is usually one obligation satisfied evenly over time, so little changes. The difficulty arrives with bundles. If you sell platform access together with implementation, data migration or training, each element may need its own treatment. Access is recognised over the term, while a one-off set-up might be recognised when it is completed, if it is genuinely distinct from the software. The FRC explainer is the best place to start; if you want sector commentary, the FRC factsheets page lists a factsheet on revenue from contracts with customers.
A few questions to ask about each contract:
- Could the customer benefit from the set-up work without the subscription, or is it only useful with it?
- Is the price for each element stated in the contract, and is it reasonable compared with what you charge separately?
- Are there usage-based fees, discounts or credits that vary the price over time?
- Does the contract allow termination, and what happens to prepayments if it does?
If you are a micro-entity or a small company applying a different regime, the details may differ, so confirm which framework your accounts follow before changing anything.
VAT: the timing that does not follow your journals
Deferral is an accounting concept. VAT has its own timing. Revenue states that where no invoice is issued, VAT becomes due on the date of supply or the date you receive payment in advance. Where you do issue an invoice, VAT generally becomes due earlier than the supply date, so read the full Revenue guidance for how invoice dates interact with payments.
The effect for a SaaS business is that a prepaid annual contract can create a VAT liability in the VAT period when you invoice or are paid, while the revenue in your management accounts is spread across twelve months. Your VAT return and your profit and loss account will therefore not match, and that is normal. What is not acceptable is guessing.
There is a second layer. Software delivered electronically is an electronically supplied service, and place of supply rules can differ from your revenue recognition timing. Whether you charge Irish VAT, apply the reverse charge or account for VAT in another member state depends on who the customer is and where they are. Record the customer's location and business status at the point of sale, because retrofitting this later is slow and error-prone.
A sensible practice is to keep a simple reconciliation that runs from invoices and receipts to deferred revenue, then to VAT. If you can explain each difference between the three, a Revenue query becomes much easier to answer.
Why investors and lenders care about it
Deferred revenue changes how your financial health reads:
- Profit: revenue recognised is lower than cash collected in a fast-growing annual-billing business, so profit can look weaker than cash suggests.
- Cash: annual prepayments flatter your bank balance. Without a schedule, it is easy to spend cash that you still owe in service.
- Working capital: a large deferred revenue balance depresses net current assets, which can matter for covenants or when you apply for credit.
- Valuation: buyers and investors will test whether your revenue is truly recurring and whether the deferred balance has been calculated properly.
For a practical take on what to track alongside deferred revenue, such as annual recurring revenue, churn and billings, a monthly management pack does the job better than a year-end spreadsheet. We cover that on our management accounts page.
Our perspective: treat revenue as a system, not a year-end task
Most of the deferred revenue problems we see in Irish SMEs do not start with the accounting standard. They start with disconnected processes. Billing sits in one tool, bookkeeping in another, VAT is prepared from a third set of numbers, and the year-end accounts are assembled from all of them in a rush.
The approach we take is to keep these tasks connected. The invoice that triggers VAT should be the same record that feeds the deferred revenue schedule, which should be the same record that shows up in your management accounts. When one number changes, the others change with it, and everyone can see why. That visibility is what makes the figures accountable, and it is the difference between a balance sheet you can defend and one you hope nobody asks about.
For a SaaS founder, we would put three habits first:
- Build the schedule from the contract, not the invoice. Start date, end date, price and any separate elements all live in the agreement.
- Reconcile monthly. Deferred revenue per the ledger should equal the sum of unreleased amounts on your schedule. Differences are far easier to find in a month than in a year.
- Decide the policy once, in writing. How you treat set-up fees, trials and refunds should be documented, so your accountant, your auditor and your next hire apply the same rules.
Our accountants are ACCA-qualified and work on cloud platforms such as Xero, QuickBooks and Sage, which means schedules and journals can live next to the transactions that create them.

Common mistakes in SaaS deferred revenue
- Booking annual cash straight to revenue. It overstates profit in the first month and understates it afterwards. This is the most frequent error in early-stage accounts.
- Ignoring the period end. Even a simple monthly plan can need a cut-off adjustment at year end.
- Treating set-up and subscription as one line. Under the revised Section 23 thinking, distinct elements may need separate treatment.
- Assuming VAT follows revenue recognition. As above, payment in advance can bring VAT forward.
- No reconciliation. If nobody ties the schedule to the balance sheet, errors compound quietly.
- Forgetting multi-year deals. The balance beyond twelve months belongs in non-current liabilities.
- Not keeping contract evidence. A schedule without the underlying contract is hard to defend.
A simple monthly process you can run
You do not need specialist revenue software on day one. A small SaaS company can run this in a cloud accounting package plus a spreadsheet, as long as it is disciplined:
- Export the month's invoices and receipts from your billing system.
- Add each new contract to the schedule with start date, end date and amount excluding VAT.
- Calculate the release for the month and post the journal (debit deferred revenue, credit revenue).
- Check that closing deferred revenue on the schedule equals the ledger balance.
- Reconcile VAT on sales to invoices and payments in advance for the VAT period.
- Review the movement: new billings, releases, refunds and any contract changes.
Once volumes grow past a few hundred active subscriptions, specialist billing and revenue tools earn their place, but the process stays the same, so it is worth getting right early.

FAQ
What does deferred revenue mean in accounting?
It is money received, or billed, for goods or services you have not yet delivered. It is recorded as a liability on the balance sheet and moved to revenue as you deliver. It is not profit at the point you collect it.
How do I account for subscription revenue?
For a typical subscription, spread the price over the service period. Debit cash and credit deferred revenue when you are paid, then each month debit deferred revenue and credit revenue. From accounting periods beginning on or after 1 January 2026, check whether the contract has several promises that need separate timing under the new FRS 102 revenue section.
What is the difference between deferred revenue and service revenue?
Deferred revenue is the part of the price you have not yet earned, so it sits on the balance sheet. Service revenue is the part you have earned by delivering the service, so it sits in the profit and loss account. Each month, a slice moves from the first to the second.
Is deferred revenue subject to VAT in Ireland?
VAT follows its own timing rules, not your deferral schedule. Revenue says that VAT can be due on receipt of payment in advance, so a prepaid annual plan may create a VAT liability before the revenue is recognised. Your accountant should confirm the position for your invoicing and customer mix.
