OxfordAQA A-Level Accounting: Verification of accounting records (9615)

This study guide teaches section 3.1.4, Verification of accounting records, of the OxfordAQA International AS and A-level Accounting (9615) specification, Version 1.2, for International AS exams May/June 2025 onwards and International A-level exams May/June 2026 onwards. Section 3.1.4 is International AS content. It is assessed on Paper 1: Introduction to Financial Accounting, which covers sections 3.1.1 to 3.1.6 and 3.1.8. Nothing in this section is International A-level only, but the specification notes that the A-level papers build on the knowledge and skills from the AS course.

Course links: the OxfordAQA A-level Accounting hub, the printable checklist and the free 10-minute diagnostics. After this guide, use the revision notes and the practice questions. For where this topic sits in the course, see the role of the accountant and the OxfordAQA A-level exam preparation page.

The benefits and limitations of verification techniques	Say which errors each technique reveals and which it does not

Errors: revealed and not revealed by a trial balance

A trial balance lists every ledger balance at one date. If total debits do not equal total credits, there is at least one error. The specification names four errors a trial balance reveals:

Error	Meaning	Illustration
Addition	A book of prime entry or ledger account is totalled wrongly	Returns inwards journal added up 100 too high
Partial omission	One half of the double entry is missing	Cash book credited for a payment, expense account never debited
Transposition	Digits swapped in one entry only	3,470 posted to one account as 3,740; the difference, 270, divides by 9
Unequal posting	Debit and credit entered at different amounts	Debit of 800, credit of 880

It names six errors a trial balance does not reveal, because each leaves debits equal to credits:

Error	Meaning	Illustration
Commission	Right amount, right class of account, wrong account	Invoice for L Hartigan posted to L Harrigan
Complete reversal	Right accounts, right amount, sides swapped	Payment to a supplier debited to bank, credited to the supplier
Compensating	Two errors of the same value cancel	Rent account and revenue account both overcast by 50
Omission	Transaction not recorded at all	A credit note never entered
Original entry	Wrong figure in the book of prime entry, used for both sides	Invoice for 1,860 entered as 1,680
Principle	Entry in the wrong class of account	Shop fittings debited to purchases

The specification also says the relevant errors from these lists apply to control accounts and bank reconciliations, so learn them in that wider sense too.

Correcting errors: the general journal and suspense account

When a trial balance does not agree, the difference is placed in a suspense account so a draft set of statements can be prepared. Each error is corrected through the general journal: date, account debited, account credited, amounts and a short narrative.

Rules to keep:

• Only errors that caused the imbalance go through suspense.
• Errors not revealed by the trial balance are corrected between the ledger accounts concerned.
• When every correction is posted, the suspense account must have a zero balance.

Worked example 1: suspense account and corrected profit

Marchetti Print Services, a sole trader, extracted a trial balance at 31 March 2026. Debits totalled 214,895 and credits 213,975. The draft profit for the year was 37,850. These errors were found.

1. The purchases journal was overcast by 1,000.
2. Discounts received of 265 were entered in the supplier’s account but not in the discounts received account.
3. Wages of 3,470 were correctly entered in the cash book but posted to the wages account as 3,740.
4. Carriage outwards of 615 was entered in the cash book but not posted to the ledger.
5. Office equipment bought for 2,800 was debited to office expenses. Ignore depreciation.
6. A credit sale of 1,860 to R Duval was entered in the sales journal as 1,680.

Step 1. Debits exceed credits by 214,895 − 213,975 = 920, so suspense opens with a credit of 920.

Step 2. Journal entries (narratives shortened):

                                       Dr       Cr
1  Suspense                         1,000
     Purchases                               1,000
   Purchases journal overcast
2  Suspense                           265
     Discounts received                        265
   Partial omission corrected
3  Suspense                           270
     Wages                                     270
   Transposition, 3,740 - 3,470
4  Carriage outwards                  615
     Suspense                                  615
   Partial omission corrected
5  Office equipment                 2,800
     Office expenses                         2,800
   Error of principle corrected
6  R Duval                            180
     Revenue                                   180
   Error of original entry, 1,860 - 1,680

Step 3. The suspense account clears.

                   Suspense account
Purchases          1,000 | Balance b/d          920
Discounts received   265 | Carriage outwards    615
Wages                270 |
                   -----                      -----
                   1,535                      1,535

Step 4. Corrected profit.

Draft profit for the year                37,850
Add: purchases overstated                 1,000
     discounts received omitted             265
     wages overstated                       270
     office equipment expensed            2,800
     revenue understated                    180
Less: carriage outwards omitted            (615)
Corrected profit for the year            41,750

The effect of errors on financial statements

For each error ask two questions. Does it change profit? Does it change an asset, liability or capital figure? Then redraft. The specification expects you to redraft statements, not only list effects.

Worked example 2: redrafting the statement of financial position

Marchetti’s draft statement showed the suspense credit as a current liability. Opening capital was 44,590 and drawings 26,000.

                              Draft      Redrafted
Non-current assets
  Office equipment           18,400        21,200
  Vehicles                   22,600        22,600
                             41,000        43,800
Current assets
  Inventory                   9,350         9,350
  Trade receivables          12,470        12,650
  Bank                        3,180         3,180
                             25,000        25,180
Current liabilities
  Trade payables              8,640         8,640
  Suspense                      920             -
                              9,560         8,640
Net current assets           15,440        16,540
Net assets                   56,440        60,340

Equity
  Opening capital            44,590        44,590
  Profit for the year        37,850        41,750
                             82,440        86,340
  Less drawings             (26,000)      (26,000)
                             56,440        60,340

Profit rose by 3,900, and so did net assets: 2,800 equipment + 180 receivables + 920 suspense removed. If the two changes did not match, a correction has been missed.

Bank reconciliation statements

The cash book (bank columns) and the bank statement record the same account from opposite sides. They differ because of timing (unpresented cheques, outstanding lodgements), items the business has not yet recorded (bank charges, credit transfers, direct debits, dishonoured cheques) and errors on either side.

Method:

1. Update the cash book for items on the bank statement not yet recorded, and correct cash book errors.
2. Balance the updated cash book.
3. Reconcile: start with the bank statement balance, add outstanding lodgements, deduct unpresented cheques, and arrive at the updated cash book balance.

Worked example 3: Heronsgate Bakery, 30 June 2026

The cash book showed a debit (favourable) balance of 3,860. The bank statement showed bank charges 75, a credit transfer from a customer 1,240, a direct debit for insurance 310 and a customer’s cheque of 520 dishonoured. A cheque for 486 to a supplier had been entered in the cash book as 468. Cheques for 1,430 and 695 were unpresented; a lodgement of 1,890 had not yet reached the bank statement.

            Cash book (bank columns), updated
Balance b/d        3,860 | Bank charges           75
Credit transfer    1,240 | Direct debit          310
                         | Dishonoured cheque    520
                         | Cheque error           18
                         | Balance c/d         4,177
                   -----                       -----
                   5,100                       5,100

Bank reconciliation statement at 30 June 2026
Balance per bank statement                 4,412
Add: outstanding lodgement                 1,890
                                           6,302
Less: unpresented cheques (1,430 + 695)   (2,125)
Balance per updated cash book              4,177

The 4,177 goes in the statement of financial position, not the bank statement figure.

Trade receivables and trade payables ledger control accounts

A control account totals a whole ledger from figures in the books of prime entry. In this specification the control accounts are memorandum records: the individual customer and supplier accounts carry the double entry. The closing balance of the control account is compared with the total of the list of individual balances.

Trade receivables ledger control
Debit	Balance b/d (debit), credit sales, interest charged on overdue accounts, dishonoured cheques, refunds to customers, balance c/d (credit)
Credit	Balance b/d (credit), receipts, discounts allowed, sales returns, irrecoverable debts, contra entries, balance c/d (debit)

Trade payables ledger control
Debit	Balance b/d (debit), payments, discounts received, purchases returns, contra entries, balance c/d (credit)
Credit	Balance b/d (credit), credit purchases, refunds from suppliers, balance c/d (debit)

The four items the specification names:

• Contra entries. A firm that is both a customer and a supplier can have its two balances set off: debit trade payables control, credit trade receivables control.
• Interest charged on overdue accounts increases the customer’s debt: debit receivables control.
• Credit balances in the receivables ledger (a customer has overpaid) and debit balances in the payables ledger (you have overpaid a supplier) are carried down on the opposite side. Never net them off against the main balance.
• Cash sales, cash purchases and provisions for doubtful debts are left out: they do not change what any credit customer or supplier owes.

Worked example 4: Corrigan Hardware, April 2026

Receivables ledger balances on 1 April: debit 24,560, credit 380. Credit sales 41,720; cash sales 5,300; receipts 36,940; discounts allowed 820; sales returns 1,150; irrecoverable debts 690; interest on overdue accounts 145; dishonoured cheque 610; contra 2,300; increase in provision for doubtful debts 400. Credit balances on 30 April: 260.

             Trade receivables ledger control
Balance b/d            24,560 | Balance b/d              380
Credit sales           41,720 | Bank (receipts)       36,940
Interest charged          145 | Discounts allowed        820
Dishonoured cheque        610 | Sales returns          1,150
Balance c/d               260 | Irrecoverable debts      690
                              | Contra                 2,300
                              | Balance c/d           25,015
                       ------                         ------
                       67,295                         67,295

Cash sales and the provision are excluded. The list of debit balances totalled 25,195. The difference of 180 was traced to an invoice posted twice to one customer’s account. Corrected, the list agrees at 25,015.

Benefits and limitations of the verification techniques

Technique	Benefits	Limitations
Trial balance	Reveals addition, partial omission, transposition and unequal posting errors; gives a starting point for the financial statements	Does not reveal commission, complete reversal, compensating, omission, original entry or principle errors
Bank reconciliation	Checks the cash book against an independent record; finds unrecorded bank items and cash book errors such as a wrong amount	An error made identically in both records, such as a cheque written for the wrong amount, stays hidden; only checks the bank account
Control accounts	Localise errors to one ledger; give a quick total of receivables and payables; deter fraud when a different person keeps them	An error of original entry or a total omission flows into both the control account and the ledger, so they still agree; commission errors between two customers are not revealed

Agreement shows the arithmetic is consistent. It does not prove the records are correct.

Common errors to avoid

• Putting every correction through suspense, including errors of principle and commission.
• Netting a credit balance in the receivables ledger against the debit balance.
• Including cash sales or the provision for doubtful debts in a control account.
• Reconciling from the original cash book balance instead of the updated one.
• Changing profit for an error that touches no income or expense account, such as a commission error between two customers.
