📚 Year 8 SQA Accounting: Case Study Practical Exercise | 案例分析实战演练

In this case study, we will follow Lucy, who starts a small lemonade stand. She makes several transactions during her first week of trading. By working through this real-life example, you will practise recording transactions, preparing a trial balance, and creating simple financial statements – essential skills for SQA Accounting.

在本案例中，我们将跟随露西，她创办了一个小型柠檬水摊位。她在第一周经营中发生了多笔交易。通过这个贴近实际的例子，你将练习记录交易、编制试算平衡表并制作简单的财务报表——这些是SQA会计的关键技能。

The following transactions took place:

发生了以下交易：

2. Identifying Account Types | 识别账户类型

Before recording transactions, we must identify which accounts are affected. Accounts fall into five categories: assets, liabilities, capital (equity), income and expenses. Every transaction changes at least two accounts, following the dual‑effect principle.

在记录交易之前，我们必须识别哪些账户会受到影响。账户分为五类：资产、负债、资本（所有者权益）、收入和费用。每笔交易至少改变两个账户，遵循双重影响原则。

Transaction 1 increases the business bank account (an asset) and increases capital (equity). Transaction 2 reduces cash (asset) and increases purchases (an expense). Transaction 3 reduces cash (asset) and adds equipment (another asset). Transaction 4 raises cash (asset) and generates sales income (income). Transaction 5 decreases cash and records advertising expense. Transaction 6 reduces cash and reduces capital through drawings. Transaction 7 creates accounts receivable (asset) and records sales income, even though cash is received later. Transaction 8 swaps one asset (receivable) for another (cash). Transaction 9 reduces cash and records supplies expense. Transaction 10 reduces cash and records rent expense.

交易1增加了企业银行存款（资产）并增加了资本（所有者权益）。交易2减少现金（资产）并增加采购成本（费用）。交易3减少现金并增加设备（另一项资产）。交易4增加现金并产生销售收入（收入）。交易5减少现金并记录广告费用。交易6通过提款减少现金并减少资本。交易7产生应收账款（资产）并记录销售收入，尽管现金以后才收到。交易8将一项资产（应收款）转换为另一项资产（现金）。交易9减少现金并记录物料费用。交易10减少现金并记录租金费用。

3. Recording Transactions Using T-Accounts | 使用T型账户记录交易

In double‑entry bookkeeping, each transaction is recorded with a debit entry (left side) and a credit entry (right side). The total debits must equal total credits. We use T‑accounts to show increases and decreases for each account.

在复式记账中，每笔交易都记录一笔借方（左侧）和一笔贷方（右侧）。借方总额必须等于贷方总额。我们使用T型账户来显示每个账户的增加和减少。

For example, when Lucy invests £100, we debit Cash and credit Capital:

例如，露西投入100英镑时，我们借记现金、贷记资本：

Debit: Cash £100

借记：现金100英镑

Credit: Capital £100

贷记：资本100英镑

Below is the complete Cash T‑account after all transactions:

以下是所有交易后的完整现金T型账户：

The balancing figure of £82 is carried down to the next period as a debit balance, representing the cash still held.

平衡金额82英镑结转至下期作为借方余额，代表仍持有的现金。

Other T‑accounts are opened similarly: Sales will have a credit balance of £65, Purchases a debit of £20, Advertising a debit of £5, and so on. Equipment (table and chairs) shows a debit balance of £30, Accounts Receivable starts with a debit of £15 and is reduced by the £15 receipt to zero.

其他T型账户类似开设：销售收入将有贷方余额65英镑，采购费用借方20英镑，广告费借方5英镑，等等。设备（桌椅）显示借方余额30英镑，应收账款起初借方15英镑，随后收到15英镑后减少至零。

4. Preparing a Trial Balance | 编制试算平衡表

A trial balance lists all account balances in debit and credit columns. It checks the arithmetic accuracy of double‑entry records. If total debits equal total credits, the books are said to be ‘balanced’.

试算平衡表将所有账户余额列在借方和贷方栏。它用于检查复式记录的算术准确性。如果借方总额等于贷方总额，账簿就是“平衡的”。
