Accrued Expenses: Costs You Owe but Haven't Paid

Picture December 31st. The office lights burned all month, the staff worked through the 31st, the auditor finished fieldwork on the 28th — and not a single invoice for any of it has arrived. Has the business incurred costs? Obviously: the power was consumed, the labour was given, the audit work was done. Accrued expenses are accounting's refusal to pretend otherwise. The meaning is pure matching: costs belong to the period that consumed them, not the period the paperwork arrived. So December's books record the electricity, the three days' wages, the audit fee — as expenses with a matching liability called Accrued Expenses — even though every dirham is still unpaid and most of it unbilled. When January's bills arrive, they settle against the accrual. The profit story stays truthful; the cash story follows in its own time. That separation — cost when consumed, cash when paid — is the entire philosophy of accrual accounting in one month-end routine.

The mechanics never vary. Step one, identify: at month-end, ask 'what did we consume but not get billed for?' — utilities, wages for days worked, rent days, interest days, unbilled professional work. Step two, estimate: best basis available — last bill, contract rate, days × daily rate — and document the basis in one line. Step three, book: debit each expense account, credit Accrued Expenses (one liability account, or separate lines for clarity). Step four, reverse: on the first day of the next month, reverse every accrual in full — debit Accrued Expenses, credit the expense accounts. Step five, true up: when actual bills arrive, book them normally into the now-clean month; estimate differences land where they belong. Five steps, same every month, most of it automatable. The routine's beauty is that errors self-correct: overestimate December and January's true-up fixes it automatically. No month-end adjustment is more forgiving — or more foundational.

Numbers make it concrete. Your monthly payroll is AED 54,000 for 30 days — AED 1,800 a day. Payday is the 5th of each month, covering the previous calendar month. On 31 December, staff have worked 29, 30, and 31 December — three days, AED 5,400 — that won't be paid until 5 January. Without the accrual: December's profit omits AED 5,400 of labour cost it genuinely used, and January carries AED 59,400 for a month it only partly worked. With the accrual: 31 December — Dr Salaries Expense 5,400 / Cr Accrued Expenses 5,400. December's profit is honest. 1 January — reverse: Dr Accrued Expenses 5,400 / Cr Salaries Expense 5,400. 5 January — the AED 54,000 payroll posts normally. January's expense: 54,000 − 5,400 (reversal) = AED 48,600 for the days actually worked in January... plus the cycle continues. Every month bears exactly its days. The alternative — no accrual — misstates two months to save one journal. No contest.

The family portrait — three adjustments, three timings. Accrued expense: cost incurred, cash later, obligation certain (December electricity — you know you used it). Provision: cost probable, cash later, obligation uncertain in amount or timing (warranty claims — history says they'll come). Prepayment: cash now, cost later, benefit certain (annual insurance — you paid for future months). Accruals and provisions are both liabilities (you'll pay); prepayments are assets (you've paid). Accruals reverse next month automatically; provisions stand until used or released; prepayments release gradually as benefit arrives. The confusion to avoid: an accrual is not a provision — accruals are near-certain and routine, provisions are judgmental and disclosed. And neither is a payable — payables are invoiced and definite. Four categories, four treatments, one principle: each cost in its own period.

The reversing entry deserves its own section because it's the most skipped step — and skipping it breaks everything. What reversal does: on day one of the new month, it exactly undoes each accrual (Dr Accrued Expenses / Cr Expense), returning the expense accounts to zero for the new month's actual activity. Why it's essential: without it, January's actual electricity bill would double-count — once as December's accrual, once as January's bill. The reversal also creates the self-correcting property: estimated AED 2,200, actual AED 2,310 — the AED 110 variance lands in January automatically, no adjusting entry needed. How to never forget: use your software's reversing-journal feature (it posts the reversal automatically on a date you set), or make reversals the first task of every new month's checklist. The rule is absolute: every accrual reverses. An accrual that doesn't reverse isn't conservative — it's an error accumulating interest in confusion.

The recurring cast, so month-end identification becomes a checklist rather than a memory test. Utilities: electricity, water, telecom — estimate from last bill adjusted for season. Payroll: days worked but unpaid at month-end — days × daily rate. Rent: if the invoice lags occupancy, accrue the days. Interest: loan interest accrued since last payment — principal × rate × days/365. Professional fees: auditor, lawyer, consultant work performed but unbilled — per engagement terms. Bonuses and commissions: earned but payable later — per the scheme rules. Government fees: trade licence amortisation is technically a prepayment release, but accrued fees (unbilled penalties, visa costs incurred) accrue. Insurance: only if the premium invoice hasn't arrived (if paid, it's a prepayment — the mirror). Run this list every month-end; most months only three or four apply, and the amounts barely move. The checklist turns judgment into routine.

Quantify the cost of skipping, because 'we'll catch up' is expensive. A business with AED 12,000 of monthly accruals — utilities, wages for days worked, loan interest, unbilled professional fees — that skips them reports every month's profit overstated by AED 12,000, and the following month, when the bills land, understated by the same. Management sees a sawtooth and can't tell whether the business is improving. Bonuses calculated on unadjusted monthly profit overpay. A lender reviewing quarterly management accounts sees volatility that isn't real. And at year-end, the auditor's first adjustment is the missing accruals — a comment on control weakness that colours the whole audit. The total year's profit is unaffected (it all washes out), which is exactly why skipping feels harmless and is so corrosive: the damage is entirely in the monthly truth that decisions are made on.

Where accruals appear and how readers use them. Balance sheet: Accrued Expenses sits in current liabilities — obligations due within the year. A growing balance isn't automatically bad (it may just reflect growth), but a balance that never moves is either an error or a provision in disguise — investigate. Profit and loss: each expense line carries its true period cost, making margins comparable month to month. Cash flow statement: the change in accruals adjusts profit back toward cash — rising accruals (more cost recognised than paid) are added back to profit in operating cash flow. Readers' lens: analysts check that accruals move sensibly with the business (accruals growing far faster than revenue can signal aggressive expense deferral — though for expenses it's usually the reverse risk: missing accruals flattering profit). For owners, the statement effect to internalise: accruals are why profit can be lower than the bank balance suggests — costs recognised before cash leaves.

The one-liner: 'We used December's electricity in December, so December's profit includes it — even though the bill arrives in January.' For a partner questioning a weak December: 'It's not weak — it carries its full costs, including AED 12,000 we haven't been billed for yet. January will look better when those bills land, but December is the honest month.' For staff: 'record what we used, not what we paid' — the entire accrual instinct in eight words. For the auditor: the accrual working (basis, estimate, reversal) filed monthly — the smoothest part of the audit file. The concept clicks instantly because everyone has lived it: the phone bill always covers last month. Accruals just apply that everyday experience to the whole business, systematically, every month. Once the instinct lands, provisions and prepayments follow naturally — they're the same period-thinking in different directions. The accrual habit, once built, changes how you see every bill. The electricity invoice arriving in January no longer feels like January's cost — you recognise it as December's, already accounted for, merely settling now. That shift — from cash-thinking to period-thinking — is the real prize of the accrual routine. It extends naturally: the rent-free period in a new lease gets spread, the annual bonus gets accrued monthly, the audit fee is recognised as the work happens. Each application is the same instinct: which period benefited? Ask it about every material cost, every month, and the books will tell the truth about performance while cash tells the truth about liquidity — two honest stories, each in its own time, never confused.

You did not start a business to become an accountant, and this guide was never meant to turn you into one. Its job is narrower: to give you enough understanding that you can read your own numbers, ask sharp questions, and spot trouble early. The doing — the daily entries, the reconciliations, the VAT filings, the month-end close — is exactly what our monthly bookkeeping team handles for UAE founders every day. We keep your chart of accounts clean, your accrual accounting correct, and your reports ready before you need them, so the numbers you read are numbers you can trust. If your books are behind, messy, or simply non-existent, that is the normal starting point for most of our clients, not a confession. Bring us the bank statements and the shoebox of receipts; we will build the rest. Book a review and we will show you, on your own figures, what this guide taught you to look for.
