Update the cash book for items appearing on the bank statement but not yet in the cash book

What this dot point is asking

SEAB wants you to update the cash book for items that appear on the bank statement but are not yet in the cash book. This is the first step before preparing a bank reconciliation statement. The central insight is that the bank often knows about transactions before the business records them, so the business must bring its cash book up to date before comparing it with the bank statement.

The answer

Why the cash book needs updating

The bank processes some transactions automatically: it deducts charges, pays standing orders, and adds interest, without the business writing them up first. These appear on the bank statement before they reach the cash book. Before reconciling, the business records them so the cash book is current.

Items the bank knows first

Payments reduce the cash book balance (credit side); receipts increase it (debit side).

The dishonoured cheque

When a customer's cheque bounces, the receipt the business recorded never really happened. It is reversed by crediting the cash book (reducing the balance), and the customer's account is debited again because they still owe the money.

After updating

Once these items are entered, the cash book shows the corrected balance. Only then do you prepare the bank reconciliation statement to deal with timing differences (the next dot point).

Examples in context

Example 1. A surprise charge. A business is confident its cash book is right, but the bank statement shows a \60$account fee it never recorded. Because the bank deducted it automatically, the business credits the cash book with$\$60$, lowering its balance to match reality. This shows why the cash book, not the bank, is the one that usually needs updating for such items.

Example 2. A bounced cheque. A customer pays \400$by cheque, which the business records as a receipt, but the cheque later bounces. The business credits the cash book$\$400$ to undo the receipt and debits the customer again, who still owes the money. Without this update, the cash book would overstate the bank balance by \400$.

Try this

Q1. State the side of the cash book on which a standing order payment is recorded. [1 mark]

• Cue. The credit side, because it is a payment that reduces the balance.

Q2. Interest received of \25$ appears on the bank statement only. State the entry in the cash book. [2 marks]

• Cue. Debit the cash book \25$ (a receipt), increasing the balance.

Q3. Explain why the cash book must be updated before preparing the reconciliation statement. [2 marks]

• Cue. Items like charges and interest belong in the cash book, not the reconciliation; updating first gives a corrected balance so only genuine timing differences remain to reconcile.
