ACCT90004 Chap.2 Accruals, Double Entry and Trial Balance
Accruals, Double Entry and Trial Balance
Accrual accounting records economic activity when it occurs rather than when cash moves. This chapter translates that principle into debits, credits, ledgers and a trial balance. It links each entry to the accounting equation and treats the trial balance as a control with limits.
The key skill is to identify timing, choose both affected accounts, post their directions and test the closing balances without assuming that equal columns prove every entry is correct.

Accrue an unpaid utility bill
- 1Recognise the resource consumption in June because that is when the expense occurs.
- 1Debit Utilities Expense for $1,200.
- 1Credit Accrued Expenses for $1,200 because payment remains due.
- 1June profit falls by $1,200 and liabilities rise by $1,200.

Accruals, Double Entry and Trial Balance FAQ
Why can profit differ from cash flow?
Accrual accounting recognises revenue when earned and expenses when incurred, while cash may move earlier or later. Credit sales, prepayments, accrued bills and depreciation therefore separate profit from the period's net cash movement even when every journal is correct.
What does a trial balance prove?
It proves that the debit balances and credit balances in the ledger total equally at that point. It does not prove correct classification, timing or measurement because a complete but wrong entry can preserve equality.
How can I choose debit or credit reliably?
Start with the account's statement element and whether it increases or decreases. Assets and expenses normally increase with debits; liabilities, equity and income normally increase with credits. Then confirm the second effect keeps the accounting equation balanced.
How do I audit a journal before posting it?
Confirm the recognition date, accounts, amounts and debit-credit directions, then describe the equation effect in words. Check that the narration matches the evidence and that the entry has not processed cash or performance twice. After posting, reconcile each affected closing balance rather than relying only on equal totals.
Exam move
Practise double entry as a four-stage routine. Write the event and recognition date, identify the two or more affected statement elements, determine each direction and only then assign debit or credit. Use small T-accounts to carry opening balances through several transactions, because isolated journal drills do not test whether you can derive closing amounts.
Include cash sales, credit purchases, accrued expenses, customer deposits and owner funding in the same set. At the end, extract a trial balance and deliberately insert one-sided and two-sided errors to see which controls detect them. Keep an error log that distinguishes direction mistakes from timing, omission, transposition and wrong-account mistakes.
Rework missed entries without viewing the answer, then narrate why each side belongs in the period. Before the exam, complete a mixed case under time pressure and reserve a final check for equality, account nature and whether every fact has been processed once. This sequence turns debit and credit rules into consequences of classification rather than memorised symbols. Extend each drill into an audit trail.
Attach a short source fact to the journal, post it into named ledger accounts and show where each closing balance appears in the trial balance. Work backwards as well: start from a closing balance and a set of movements, derive the missing transaction and state its journal. This prevents familiarity with common entries from replacing actual reconciliation.
Create error sets containing an omitted entry, an entry posted twice, a transposition, a debit to the wrong asset and a correct two-sided amount in the wrong period. Predict whether the trial balance detects each error before checking the columns. For accrual timing, maintain separate cash and expense timelines so a July payment cannot pull a June obligation into the wrong period.
Rehearse compound entries with more than two accounts only after simple directions are secure. Use narration to explain the event and avoid descriptions such as adjustment that reveal nothing. In a timed set, number every source fact and tick it once when processed. Complete three closing controls: debits equal credits, the accounting equation balances and each account's movement agrees with the economic event.
Record which control caught the mistake, because that evidence shows which checking habit deserves more practice. Repeat the same transaction with cash arriving one period earlier and one period later so recognition remains anchored to the event date.
