We will record transactions, prepare T-accounts, produce a trial balance, and build financial statements from scratch. By working through this realistic scenario, you will understand how each transaction affects the financial position of a business and why accuracy matters at every step.
欢迎参加为 CCEA Year 9 学生设计的会计实操案例分析。在这个演练中，你将扮演一位小型企业主，运用所学的基础会计知识。我们将记录交易、开设 T 型账、编制试算平衡表，并从头制作财务报表。通过这个真实情景的模拟，你将理解每一笔交易如何影响企业的财务状况，以及为什么每个步骤的准确性都至关重要。
1. Meet the Business | 认识这家企业
Lucy, a Year 9 student, decides to turn her baking hobby into a small business called ‘Lucy’s Bakes’. She starts on 1 April 2024 with £200 of her own savings and a £100 bank loan from her parents. Her plan is to sell cupcakes and brownies at the local Sunday market. She opens a business bank account to keep her personal money separate from the business finances.
露西是一名 Year 9 学生，她决定把自己的烘焙爱好变成一家名为“Lucy’s Bakes”的小企业。她在 2024 年 4 月 1 日开始经营，投入自己的储蓄 200 英镑，并从父母那里获得 100 英镑的银行贷款。她计划在当地的周日集市上售卖纸杯蛋糕和布朗尼。她开设了一个企业银行账户，将个人资金与企业财务分开。
2. The Opening Entry: Capital and Loan | 期初分录：资本与贷款
The very first transaction involves Lucy introducing her capital. The double entry is: debit Bank £200 (the asset increases), credit Capital £200 (the owner’s equity increases). At the same time, the bank loan of £100 is received: debit Bank £100, credit Loan (a liability) £100. After these entries, the bank balance stands at £300, and the accounting equation (Assets = Capital + Liabilities) is in equilibrium.
第一笔交易是露西投入资本。复式记账为：借记银行存款 200 英镑（资产增加），贷记资本 200 英镑（所有者权益增加）。与此同时，收到银行贷款 100 英镑：借记银行存款 100 英镑，贷记银行贷款（负债）100 英镑。在这两笔分录后，银行存款余额为 300 英镑，会计等式（资产 = 资本 + 负债）保持平衡。
3. Purchasing Equipment and Ingredients | 购买设备和原材料
Lucy spends £80 on baking equipment (mixing bowls, trays, a hand mixer) on 2 April. This is recorded as: debit Equipment (a non-current asset) £80, credit Bank £80. On the same day, she buys ingredients for £30 cash: debit Purchases (an expense) £30, credit Bank £30. The bank balance drops to £190 (£300 – £80 – £30). It is important to classify equipment as an asset that will be used for several years, while ingredients are a current expense used up in making the goods.
4 月 2 日，露西花费 80 英镑购买烘焙设备（搅拌碗、烤盘、手动搅拌器）。分录为：借记设备（非流动资产）80 英镑，贷记银行存款 80 英镑。同一天，她用现金购买 30 英镑的原材料：借记采购（费用）30 英镑，贷记银行存款 30 英镑。银行余额下降至 190 英镑（300 − 80 − 30）。将设备归类为可使用多年的资产，而将原材料归为在生产商品时消耗掉的当期费用，这一点非常重要。
4. Recording a Cash Sale | 记录一笔现金销售
On her first market day, 6 April, Lucy sells 40 cupcakes at £2 each. Total cash received = £80. The double entry is: debit Bank £80 (asset increases), credit Sales (revenue) £80. Now the bank balance returns to £270. This single entry captures both the increase in cash and the revenue earned. Sales are recorded as a credit because they increase the owner’s equity.
在第一个集市日 4 月 6 日，露西卖了 40 个纸杯蛋糕，每个售价 2 英镑。现金收入共计 80 英镑。复式分录为：借记银行存款 80 英镑（资产增加），贷记销售收入 80 英镑。此时银行存款余额回升至 270 英镑。这一笔分录同时记载了现金的增加和收入的取得。销售收入记在贷方，因为它们增加了所有者权益。
5. Introducing a Credit Customer | 引入赊销客户
The following week, a local cafe ‘Brew & Bean’ offers to buy 20 brownies at £3 each on credit. Lucy agrees, delivering the brownies on 13 April and issuing an invoice. The entry is: debit Trade Receivables (debtor) £60, credit Sales £60. No cash has been received yet, but the revenue is recognised when the sale is made. This demonstrates the accruals concept – recording income when earned, not when cash changes hands.
接下来的一周，当地一家咖啡馆“Brew & Bean”提出赊购 20 个布朗尼，每个 3 英镑。露西同意，于 4 月 13 日交付布朗尼并开具了发票。分录为：借记应收账款（债务人）60 英镑，贷记销售收入 60 英镑。虽然尚未收到现金，但在销售发生时即确认收入。这体现了权责发生制概念——在赚取收入时记录，而不是在现金易手时才记录。
6. Paying for a Market Stall | 支付摊位费用
On 14 April, Lucy pays £25 for her stall pitch at the Sunday market. This is a business expense. The double entry is: debit Stall Hire (expense) £25, credit Bank £25. Expenses reduce the owner’s equity, so they are recorded as debits. After this payment, the bank balance is £245.
4 月 14 日，露西支付了 25 英镑的周日集市摊位费。这是一项企业费用。复式分录为：借记摊位租金（费用）25 英镑，贷记银行存款 25 英镑。费用会减少所有者权益，因此记在借方。付款后，银行存款余额为 245 英镑。
7. Receiving Payment from the Credit Customer | 收到赊销客户的付款
On 20 April, Brew & Bean pays the full £60 by bank transfer. This is not a new sale; it is the settlement of a debt. The entry is: debit Bank £60 (asset up), credit Trade Receivables £60 (asset down). Notice that total assets remain the same – one asset replaces another. The bank balance now becomes £305.
4 月 20 日，Brew & Bean 通过银行转账全额支付 60 英镑。这并非新的销售，而是债务的清偿。分录为：借记银行存款 60 英镑（资产增加），贷记应收账款 60 英镑（资产减少）。请注意，总资产保持不变——一项资产替代了另一项资产。银行存款余额现在变为 305 英镑。
8. Prepare the T-Accounts | 准备 T 型账户
After recording all transactions in the ledger, we can draw up the T-accounts. Here is a summary of the balances:
- Bank: Debit side £200 + £100 + £80 + £60 = £440 total debits; Credit side £80 + £30 + £25 = £135 total credits. Balance c/d = £305 (debit).
- Capital: Credit £200.
- Loan: Credit £100.
- Equipment: Debit £80.
- Purchases: Debit £30.
- Sales: Credit £80 + £60 = £140.
- Trade Receivables: Debit £60, Credit £60 – balance nil.
- Stall Hire: Debit £25.
在将所有交易记入分类账后，我们可以编制 T 型账户。以下是各账户余额的总结：
- 银行存款：借方发生额 200 + 100 + 80 + 60 = 440 英镑；贷方发生额 80 + 30 + 25 = 135 英镑。余额（借方）305 英镑。
- 资本：贷方 200 英镑。
- 银行贷款：贷方 100 英镑。
- 设备：借方 80 英镑。
- 采购：借方 30 英镑。
- 销售收入：贷方 80 + 60 = 140 英镑。
- 应收账款：借方 60 英镑，贷方 60 英镑——余额为零。
- 摊位租金：借方 25 英镑。
9. Trial Balance as at 30 April 2024 | 2024 年 4 月 30 日的试算平衡表
Using the T-account balances, we can now extract a trial balance. All debit balances must equal all credit balances.
| Account | Debit £ | Credit £ |
|---|---|---|
| Bank | 305 | |
| Equipment | 80 | |
| Purchases | 30 | |
| Stall Hire | 25 | |
| Capital | 200 | |
| Loan | 100 | |
| Sales | 140 | |
| Trade Receivables | 0 | |
| Total | 440 | 440 |
The totals agree at £440, confirming that the double entry has been carried out correctly so far. If the trial balance did not balance, we would need to check for errors such as single-sided entries or transposed figures.
借方与贷方的总额均为 440 英镑，相等，证实到目前为止复式记账正确无误。如果试算表不平，我们就需要检查是否存在单向分录或数字颠倒等错误。
10. Income Statement for April | 4 月份利润表
To find out whether Lucy’s Bakes has made a profit or a loss, we prepare an income statement. Revenue (sales) totaled £140. Expenses are Purchases £30 and Stall Hire £25, giving total expenses of £55. The calculation is:
Profit = Sales £140 − Expenses £55 = £85
This £85 net profit will be added to Lucy’s capital in the balance sheet. Note that the equipment purchase is not an expense – it is a non-current asset and appears on the balance sheet.
为了弄清 Lucy’s Bakes 是盈利还是亏损，我们需编制利润表。销售收入共计 140 英镑。费用包括采购 30 英镑和摊位租金 25 英镑，合计 55 英镑。计算如下：
利润 = 销售收入 140 英镑 − 费用 55 英镑 = 85 英镑
这 85 英镑的净利润将在资产负债表中计入露西的资本。请注意，购买设备不属于费用——它是非流动资产，将出现在资产负债表上。
11. Statement of Financial Position as at 30 April | 4 月 30 日的财务状况表
The statement of financial position (balance sheet) shows the assets, liabilities and capital of the business. We have:
- Non-current assets: Equipment £80
- Current assets: Bank £305
- Total assets: £385
Liabilities are the bank loan of £100. To find the capital figure, we start with the opening capital of £200 and add the profit of £85, giving closing capital of £285. Check the accounting equation:
Assets £385 = Capital £285 + Liabilities £100
The balance sheet balances perfectly. This confirms the financial records are consistent and complete.
财务状况表（资产负债表）列示企业的资产、负债和资本。我们有：
- 非流动资产：设备 80 英镑
- 流动资产：银行存款 305 英镑
- 总资产：385 英镑
负债为银行贷款 100 英镑。资本的计算以期初资本 200 英镑为起点，加上利润 85 英镑，得出期末资本 285 英镑。检查会计等式：
资产 385 英镑 = 资本 285 英镑 + 负债 100 英镑
资产负债表两端平衡，证实财务记录一致且完整。
12. Tips for Your Own Case Study Exam | 应对案例分析考试的技巧
When you tackle a case study in an exam, remember to read the scenario carefully and identify each transaction type. Always ask yourself: what are the two accounts affected, and do they increase or decrease? Use the DEAD CLIC mnemonic (Debit: Expenses, Assets, Drawings; Credit: Liabilities, Income, Capital) to guide your entries. Show all your workings, even for simple calculations. If the trial balance does not balance, do not panic – work backwards and check each entry. Above all, keep practicing with different scenarios to build confidence.
在考试中处理案例分析时，请务必仔细阅读情景，识别每笔交易的类型。始终问自己：受影响的两个账户是什么，它们是增加还是减少？运用 DEAD CLIC 助记法（借记：费用、资产、提款；贷记：负债、收入、资本）来指导分录。展示所有计算步骤，哪怕是简单的算式。如果试算表不平，不要慌张——逆向检查每笔分录。最重要的是，通过不同情景的多加练习来建立信心。
