欢迎来到这个为 KS3 CCEA 会计课程设计的动手案例分析课程。通过一个真实的小型企业情景，你将加深对整个会计循环的理解——从分析交易、运用复式记账规则到编制试算平衡表和最终财务报表。仔细完成每一步，把它当成你自己的小型会计项目来练习。
1. Introduction to the Case: Meet Baker's Delight | 案例概述：认识面包房
Lucy opens a small bakery called Baker's Delight on 1 March. She invests £8,000 of her own savings into the business and also takes out a bank loan of £2,000. The money is deposited into a business bank account. She then purchases baking equipment for £3,000, pays £600 for a month's shop rent, and buys ingredients worth £400 on credit from a supplier. During the first week, she makes cash sales of £1,500 and also provides a cake order to a local café on credit for £300.
露西在 3 月 1 日开了一家名为 'Baker's Delight' 的小面包房。她把自己的 8,000 英镑积蓄投入企业，又获得了 2,000 英镑的银行贷款。这些钱存入了企业的银行账户。随后她花 3,000 英镑购买了烘焙设备，支付了 600 英镑的一个月店面租金，并以赊购方式向供应商购买了价值 400 英镑的原材料。在第一周，她实现了 1,500 英镑的现金销售，并向当地一家咖啡馆赊销了价值 300 英镑的蛋糕订单。
Your task is to help Lucy record these transactions correctly, following the double-entry system. You will journalise the entries, post them to ledger accounts, extract a trial balance, and finally prepare a simple income statement and a balance sheet. The case will also challenge you to spot a common bookkeeping error and suggest how to correct it.
你的任务是帮助露西按照复式记账法正确地记录这些交易。你需要编写分录、过账到分类账、编制试算平衡表，最后编制简单的利润表和资产负债表。这个案例还会挑战你发现一个常见的记账错误，并提出如何更正。
2. The Accounting Equation and Double-Entry | 会计等式与复式记账
The foundation of all bookkeeping is the accounting equation: Assets = Liabilities + Equity. Every transaction affects at least two accounts in a way that keeps this equation in balance. For every debit entry there must be a corresponding credit entry of equal value – this is the dual aspect concept.
所有簿记的基础是会计等式：资产 = 负债 + 所有者权益。每笔交易至少影响两个账户，并保持等式平衡。每一笔借方分录必须有等额的贷方分录与之对应——这就是复式记账原则。
In a simple ledger, assets increase on the debit side, while liabilities and equity increase on the credit side. Income increases equity (credit) and expenses decrease equity (debit). Memorising the normal balances of account types is essential before you begin posting.
在简单的分类账中，资产在借方增加，负债和所有者权益在贷方增加。收入使所有者权益增加（贷方），费用使所有者权益减少（借方）。在开始过账之前，记住各账户类型的正常余额方向至关重要。
Normal Balances: Assets – Debit; Expenses – Debit; Liabilities – Credit; Equity – Credit; Income – Credit
正常余额方向：资产 — 借方；费用 — 借方；负债 — 贷方；所有者权益 — 贷方；收入 — 贷方
3. Analysing the Transactions | 分析交易
Let us break down each transaction from the Baker's Delight scenario and determine which accounts are affected and whether they should be debited or credited. This step-by-step analysis will make journal entries much easier to write.
我们来逐一拆解面包房的每笔交易，确定哪些账户被影响以及应该借记还是贷记。这种逐步分析会使得写分录容易得多。
Transaction 1: Lucy invests £8,000 cash. Cash at bank (asset) increases – debit. Capital (equity) increases – credit.
交易一：露西投入 8,000 英镑现金。银行存款（资产）增加 — 借记。资本金（所有者权益）增加 — 贷记。
Transaction 2: Bank loan of £2,000. Cash at bank (asset) increases – debit. Bank loan (liability) increases – credit.
交易二：银行贷款 2,000 英镑。银行存款（资产）增加 — 借记。银行贷款（负债）增加 — 贷记。
Transaction 3: Buy equipment for £3,000 paying immediately. Equipment (asset) increases – debit. Cash at bank (asset) decreases – credit.
交易三：购买设备 3,000 英镑并立即付款。设备（资产）增加 — 借记。银行存款（资产）减少 — 贷记。
Transaction 4: Pay shop rent £600. Rent expense (expense) increases – debit. Cash at bank (asset) decreases – credit.
交易四：支付店面租金 600 英镑。租金费用（费用）增加 — 借记。银行存款（资产）减少 — 贷记。
Transaction 5: Buy ingredients on credit for £400. Purchases (expense) increases – debit. Trade payables (creditors) (liability) increases – credit.
交易五：赊购 400 英镑原材料。采购费用（费用）增加 — 借记。应付账款（债权人）（负债）增加 — 贷记。
Transaction 6: Cash sales £1,500. Cash at bank (asset) increases – debit. Sales (income) increases – credit.
交易六：现金销售 1,500 英镑。银行存款（资产）增加 — 借记。销售收入（收入）增加 — 贷记。
Transaction 7: Credit sales £300 to café. Trade receivables (debtors) (asset) increases – debit. Sales (income) increases – credit.
交易七：向咖啡馆赊销 300 英镑。应收账款（债务人）（资产）增加 — 借记。销售收入（收入）增加 — 贷记。
4. Recording in the General Journal | 在普通日记账中记录
The general journal is where we first write down each transaction as a debit and credit entry. For KS3, you will often be asked to complete journal entries in a table with Date, Details, Debit and Credit columns. Below are the journal entries for Baker's Delight.
普通日记账是我们首次以借贷分录形式记录每笔交易的地方。在 KS3 阶段，你通常会被要求在带有日期、摘要、借方金额和贷方金额的表格中完成分录。下面是面包房的日记账分录。
| Date | Details | Debit (£) | Credit (£) |
|---|---|---|---|
| 1 Mar | Cash at Bank | 8,000 | |
| Capital | 8,000 | ||
| 1 Mar | Cash at Bank | 2,000 | |
| Bank Loan | 2,000 | ||
| 2 Mar | Equipment | 3,000 | |
| Cash at Bank | 3,000 | ||
| 2 Mar | Rent Expense | 600 | |
| Cash at Bank | 600 | ||
| 3 Mar | Purchases | 400 | |
| Trade Payables | 400 | ||
| 5 Mar | Cash at Bank | 1,500 | |
| Sales | 1,500 | ||
| 6 Mar | Trade Receivables | 300 | |
| Sales | 300 |
Notice that every journal entry has equal debits and credits. This is the first check that the accounting records are arithmetically correct. After recording in the journal, we transfer each entry to the relevant T-accounts.
请注意，每一个分录的借方和贷方金额都相等。这是检查会计记录算术正确性的第一步。在日记账中记录完毕后，我们将每笔分录过账到相关的 T 型账中。
5. Posting to T-Accounts | 过账到 T 型账簿
T-accounts provide a visual representation of each ledger account. The left side is the debit side, the right side is the credit side. We now post the journal amounts into the correct T-accounts and calculate the closing balance for each.
T 型账直观地展示了每一个分类账户。左边是借方，右边是贷方。我们现在把日记账金额过入正确的 T 型账户，并计算出每个账户的期末余额。
Let us look at the Cash at Bank account alone as an example. All cash received is debited, and all cash paid is credited. The balance is the difference between total debits and total credits.
我们单独看一下银行存款账户的例子。所有收到的现金借记，所有付出的现金贷记。期末余额是借方总额与贷方总额的差额。
| Cash at Bank | |
|---|---|
| Debit: 1 Mar Capital £8,000 1 Mar Loan £2,000 5 Mar Sales £1,500 | Credit: 2 Mar Equipment £3,000 2 Mar Rent £600 |
| Total Debits £11,500 | Total Credits £3,600 |
| Balance c/d £7,900 (Debit) | |
Similar T-accounts must be prepared for Capital, Bank Loan, Equipment, Rent Expense, Purchases, Trade Payables, Trade Receivables, and Sales. All balances are then listed in the trial balance.
同样需要为资本金、银行贷款、设备、租金费用、采购、应付账款、应收账款和销售收入准备 T 型账。所有余额随后列在试算平衡表中。
6. Preparing a Trial Balance | 编制试算平衡表
A trial balance lists all the ledger account balances as at a specific date. It checks that total debits equal total credits. Here is the trial balance for Baker's Delight as at 7 March, before any adjustments.
试算平衡表列出了一个特定日期所有分类账账户的余额。它检查了总借方是否等于总贷方。以下是面包房在 3 月 7 日的试算平衡表，尚未做任何调整。
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Cash at Bank | 7,900 | |
| Capital | 8,000 | |
| Bank Loan | 2,000 | |
| Equipment | 3,000 | |
| Rent Expense | 600 | |
| Purchases | 400 | |
| Trade Payables | 400 | |
| Sales | 1,800 | |
| Trade Receivables | 300 | |
| Totals | 12,200 | 12,200 |
The debit and credit totals are equal, so the trial balance agrees. However, a trial balance that balances does not guarantee there are no errors. For instance, a mistake Lucy made was that she recorded the £600 rent payment as a debit to equipment rather than rent expense, but then corrected it before this trial balance was prepared. We will now suppose she actually forgot to record the ingredients purchase and a double entry has been missed.
借方与贷方合计数相等，因此试算平衡表平衡。但是，试算表平衡并不保证没有错误。例如，露西以前曾将 600 英镑租金错误地记入设备借方，但后来在编制该试算平衡表前改正了过来。现在我们假设她其实忘记记录了原材料采购，有一笔复式分录被遗漏了。
7. Adjustments and Error Checking | 调整与差错检查
Let us imagine that Lucy's trial balance originally showed a difference because she omitted the credit purchase of ingredients. Total debits were £11,800 and total credits £12,200 – a difference of £400. Because the credit side was larger, a missing debit of £400 for purchases was the likely cause. When we enter the missing entry, the trial balance balances.
我们假设露西的试算平衡表最初出现了差异，因为她遗漏了原材料的赊购。那时借方合计 11,800 英镑，贷方合计 12,200 英镑，相差 400 英镑。由于贷方更大，很可能是遗漏了 400 英镑的采购借方。当我们补记这笔遗漏分录后，试算平衡表就平衡了。
Common errors at KS3 include: transposition errors (e.g. writing £540 instead of £450), omission of one side of a double entry, posting to the wrong account, and failing to include a transaction. Always recheck journal entries to spot these.
在 KS3 阶段常见的错误包括：数字颠倒（如将 450 英镑写成 540 英镑）、遗漏分录的一侧、过账到错误的账户、以及漏记整笔交易。一定要反复检查分录来发现这些问题。
Once the trial balance is correct, we can confidently use the balances to prepare the income statement and balance sheet. The income statement draws on income and expense accounts, while the balance sheet lists assets, liabilities and equity.
一旦试算平衡表正确无误，我们就可以有信心地使用这些余额来编制利润表和资产负债表。利润表基于收入和费用账户，而资产负债表列出资产、负债和所有者权益。
8. Creating the Income Statement | 编制利润表（损益表）
The income statement shows how much profit or loss the business made during a period. For Baker's Delight, the first week's revenue is the total sales and the expenses are purchases and rent. The simple formula is:
Profit = Revenue – Expenses
利润表反映企业在某一期间内赚得的利润或发生的亏损。对面包房而言，第一周的营业收入是销售总额，费用为原材料采购和租金。简单公式是：
利润 = 收入 – 费用
| Baker's Delight – Income Statement for the week ended 7 March | |
|---|---|
| Sales Revenue | £1,800 |
| Less: Purchases | (£400) |
| Less: Rent Expense | (£600) |
| Net Profit | £800 |
Net profit of £800 increases Lucy's equity. This profit will be added to the capital figure in the balance sheet. It is essential to show all expenses, including any that were used up even if not yet paid, but in our basic example all expenses have been paid or recorded.
净利润 800 英镑增加了露西的所有者权益。这份利润将在资产负债表中加入到资本金数字里。将全部费用列出非常重要，包括即使尚未支付但已消耗的费用，但在我们的基础例子中所有费用都已支付或记录。
9. Building the Balance Sheet | 编制资产负债表
The balance sheet presents the accounting equation Assets = Liabilities + Equity at a point in time. We use the capital balance of £8,000 and add the net profit of £800 to arrive at closing equity of £8,800. The balance sheet is then:
资产负债表在某一时点呈现会计等式 资产 = 负债 + 所有者权益。我们用 8,000 英镑的资本金余额加上 800 英镑的净利润，得出期末所有者权益 8,800 英镑。资产负债表如下：
| Baker's Delight – Balance Sheet as at 7 March | |
|---|---|
| Assets | |
| Equipment | £3,000 |
| Trade Receivables | £300 |
| Cash at Bank | £7,900 |
| Total Assets | £11,200 |
| Liabilities | |
| Trade Payables | £400 |
| Bank Loan | £2,000 |
| Total Liabilities | £2,400 |
