Deferred revenue and contract margin in a managed IT business
A support contract billed twelve months in advance is recognised across the twelve months it covers, with the unearned portion held as deferred income, while the VAT on it falls due by reference to the invoice date instead. This is an illustrative example set in a UK managed service provider billing annual support contracts.

- IT services
- Support contracts are invoiced twelve months in advance and recognised in full when the invoice is raised.
- Engineer time is recorded against tickets in the professional services automation tool but not against contracts, so no contract carries a cost.
- Out-of-scope work gets done and absorbed, because calling it out of scope requires a definition of scope that does not exist in writing.
- Recognising a year's billing on invoice makes the first quarter look strong and the rest of the year look weak. The business looks seasonal and is not.
- Under FRS 102, revenue from a service contract is recognised as the service is provided, so the unearned portion sits in deferred income as a creditor rather than in revenue.
- VAT does not follow the accounting. The tax point on an annual invoice raised or paid up front falls in that quarter, so a full year of VAT is payable long before the revenue is earned.
- Some contracts consume more engineer hours than they generate in revenue, and with no cost per contract there is no way to know which ones.
- Xero has no native deferred revenue schedule, so the deferral is either a monthly release journal driven by a contract schedule or an add-on that maintains one.
- A contract schedule would be built: client, start date, term, annual value, monthly release. Every new contract is added when it is signed rather than when someone notices.
- The full invoice value would post to deferred income on billing, with a monthly journal releasing one twelfth to revenue over the term. Renewals restart the schedule and mid-term changes are pro-rated on it rather than adjusted directly in revenue.
- Engineer time would be recorded against a contract as well as a ticket — ConnectWise, Autotask and HaloPSA all support it — and costed at a fully loaded rate including employer National Insurance, pension and holiday.
- Contract margin would be reported monthly: released revenue against loaded engineer cost, third-party licence cost and any hardware carried on the contract.
- Scope would be written down per tier: what is included, what is chargeable, and what triggers a tier review. Out-of-scope work then becomes a decision rather than a habit.
- The VAT position would be modelled alongside the renewal calendar, because a cluster of annual renewals in one quarter creates a VAT payment with no relationship to that quarter's profit.
- Recognising a year's billing on invoice makes a steady business look seasonal and hides which clients are served at a loss. Deferral across the term and cost per contract have to arrive together; either one alone leaves the picture wrong.
- Getting engineer time recorded against contracts is the harder half, because it changes how the delivery team works rather than how the ledger is kept.
- The business would be able to read a monthly profit figure that reflects the month rather than the billing cycle.
- Each contract would carry its own margin, so renewal pricing is set on evidence rather than on instinct.
- Deferred income on the balance sheet would show what has been billed and not yet earned, which is one of the first figures a buyer or a lender asks for.
What we'd flag
Introducing deferral makes the current year's revenue look smaller, because a portion of what was already recognised moves onto the balance sheet. That is the correct treatment and it is still an awkward conversation with a director who has been reading the old figures for years. Comparatives need restating or the trend means nothing.
