Accounting and Tax for Professional Services Businesses in the UAE

Revenue leaks before it is invoiced

In a trading business, the product either sells or sits on the shelf where you can see it. In a professional services firm, unbilled work simply evaporates. Time worked and not recorded, recorded and not billed, billed and then written down in a negotiation nobody tracked — each of those is revenue lost at a stage before it ever reached the accounts.

Which means a professional firm’s financial reporting has to start upstream of the invoice. Recorded time, work in progress, realisation, and the gap between the two are the operating reality; the invoice is what survives it.

Firms that manage from invoiced revenue alone are managing the residue and cannot see where it went.

Which businesses this applies to

Management consultancies, marketing and creative agencies, law firms, engineering and architecture practices, IT consultancies, recruitment firms, and advisory businesses of most kinds.

Particularly firms billing on time or on retainer with variable scope, firms with several fee earners where individual performance is invisible in aggregate results, and firms where the founder is still the main revenue generator and the economics of everyone else are unclear.

The work, step by step

What this looks like in practice:

1. Establish time recording as a discipline, since everything downstream depends on it and it is the step firms resist most.
2. Account for work in progress — recorded, unbilled time carried at its expected recoverable value rather than ignored.
3. Track realisation: the gap between time value recorded and amounts actually billed and collected.
4. Measure utilisation by fee earner, which is the other half of the profitability question.
5. Set revenue recognition for retainers and fixed fees, spread across the service period rather than recognised on invoice.
6. Account for disbursements separately from fee income rather than grossing them through revenue.
7. Handle VAT on services, including the place-of-supply rules for overseas clients and the reverse charge on overseas costs.
8. Report profitability by client and by engagement, which is usually where the uncomfortable answers are.

The four numbers a professional firm needs

Most owner-managed firms track revenue and profit and nothing between. The intermediate numbers are where the management information actually is:

• Utilisation — chargeable hours as a proportion of available hours, by fee earner. Low utilisation is a pipeline or a staffing problem
• Realisation — amounts billed as a proportion of time value recorded. Low realisation is a scoping, pricing or delivery problem
• Work in progress — recorded unbilled time, aged. WIP older than a couple of months is very often WIP that will never be billed
• Lock-up — WIP plus receivables expressed in days, which is the true measure of how long cash is tied up in the delivery cycle
• Profitability by client — because in most firms a small number of clients absorb a disproportionate share of unbilled effort
• Recovery on fixed-fee work — time value against the agreed fee, which is the only way to know whether the pricing works

Utilisation and realisation together explain nearly all variance in a professional firm’s profitability, and they point at completely different remedies. A firm looking only at revenue cannot tell which of the two is the problem.

VAT on services, and the export question

For a firm with international clients, the place-of-supply rules determine whether UAE VAT applies, and the analysis is less intuitive than for goods.

Services supplied to a business customer outside the UAE may fall outside the scope or be zero-rated depending on the nature of the service and where it is consumed — and the conditions have to be satisfied and evidenced rather than assumed from the client’s address. Services connected with UAE real estate, and services performed in the UAE, have their own rules that can bring a supply back into scope regardless of who is paying.

On the purchase side, professional firms buy substantially from abroad: software, research subscriptions, overseas counsel and subcontracted specialists. All of it is subject to the reverse charge, and in a firm where the net cash effect is nil the entries are routinely omitted entirely — which is one of the first anomalies noticed on a return.

Disbursements are the other recurring item. Costs incurred as agent on a client’s behalf and recharged at cost generally sit outside revenue; costs incurred as principal and recharged do not. Getting this wrong inflates turnover and distorts every margin the firm reports.

Common mistakes

The expensive mistakes in this area are consistent:

• No time recording, so the firm cannot see where its capacity actually went.
• No work in progress on the balance sheet, understating assets and hiding unbilled work until it expires.
• Retainers recognised on invoice rather than across the service period.
• Realisation never measured, so write-downs happen invisibly in individual negotiations.
• Disbursements grossed through revenue, inflating turnover and distorting margin.
• Overseas client supplies zero-rated by assumption without satisfying and evidencing the conditions.
• No reverse charge entries despite significant overseas software and subcontract costs.
• Profitability by client never calculated, so the client absorbing the most unbilled effort is often the one everyone values most.

Deadlines that apply

Time recording is daily or it does not happen. WIP should be reviewed and aged monthly, because WIP older than a couple of months is usually WIP that will not be billed and the conversation to have about it is not improving with age.

Utilisation and realisation are monthly metrics. Revenue recognition policy for retainers is set at engagement rather than at year end, and corporate tax follows at 30 September 2026 for a December year end.

What lands on your desk

• Time recording established and reported
• Work in progress carried at expected recoverable value and aged
• Utilisation and realisation reported monthly by fee earner
• Lock-up measured in days
• Revenue recognition policy for retainers and fixed fees
• Disbursements accounted for outside revenue where appropriate
• VAT with place of supply established and reverse charge applied
• Profitability by client and engagement

Documents we will ask for

The list is short and you will have most of it already:

• Time recording data, if any exists
• Engagement letters and fee arrangements, including retainers
• Billing history with any write-downs applied
• Unbilled work in progress
• Fee earner costs and available hours
• Details of disbursements and how they are currently recharged
• Client list with location, for the place-of-supply analysis
• Overseas supplier and subscription costs

Fees

Priced on fee earner count and transaction volume rather than on revenue. The setup — time recording, WIP policy, reporting structure — is a one-off fixed fee.

For firms without any time recording, the first two months are the difficult part and the value shows immediately afterwards: the first realisation report is generally the most informative single document a professional firm receives.
