Edexcel 会计 Year 12 为未来的会计学习奠定关键基础。学生需要掌握复式记账系统，理解财务数据如何记录和汇总，并能为个体经营者编制主要财务报表。本文将核心大纲内容拆分为易于掌握的模块，突出你在 AS 考试和后续学习中必须掌握的知识点。
1. The Accounting Equation and Business Documents | 会计等式与商业单据
The accounting equation forms the backbone of the double-entry system. It states that assets must always equal the sum of liabilities and capital. Every transaction affects this equation while preserving its balance.
会计等式是复式记账系统的基石。它表明资产必须始终等于负债与资本之和。每笔交易在影响等式的同时都会保持其平衡。
Assets = Liabilities + Capital
资产 = 负债 + 资本
Before any entry can be made, source documents such as invoices, credit notes, and receipts provide the evidence. You must be able to identify which document supports which transaction and understand the flow from purchase order to payment.
在做任何分录之前，发票、贷项通知单和收据等原始凭证提供了依据。你必须能识别哪种凭证支持哪种交易，并理解从采购订单到付款的流程。
2. Double-Entry Bookkeeping Rules | 复式记账规则
In double-entry bookkeeping, every transaction is recorded twice: once as a debit and once as a credit. The total debits must always equal total credits. Accounts are classified into assets, liabilities, capital, income, and expenses, each with its own debit or credit increase rule.
在复式记账中，每笔交易记录两次：一次借记，一次贷记。借方总额必须始终等于贷方总额。账户分为资产、负债、资本、收入和费用，各自有其借记或贷记的增加规则。
| Account Type | To Increase | To Decrease |
|---|---|---|
| Assets | Debit | Credit |
| Liabilities | Credit | Debit |
| Capital | Credit | Debit |
| Income | Credit | Debit |
| Expenses | Debit | Credit |
You should be able to analyse a transaction, decide which two accounts are affected, and apply the correct debit and credit entries. Practice with common scenarios such as credit sales, cash purchases, and capital introduced by the owner.
你应该能够分析一笔交易，确定哪两个账户受影响，并运用正确的借贷分录。通过赊销、现金购买和业主投入资本等常见情景进行练习。
3. Books of Prime Entry | 原始分录账簿
Before transactions reach the ledgers, they are first recorded in books of prime entry. These specialised books help organise daily transactions efficiently.
在交易进入分类账之前，会先在原始分录账簿中记录。这些专用账簿有助于高效地组织日常交易。
- Sales Day Book – records credit sales from invoices
- Purchases Day Book – records credit purchases from invoices
- Sales Returns Day Book – records returns inwards (credit notes sent)
- Purchases Returns Day Book – records returns outwards (credit notes received)
- Cash Book – combines bank and cash transactions
- Petty Cash Book – records small cash expenses using the imprest system
- Journal – records non-regular transactions, corrections, and opening entries
- 销售日记账 – 根据发票记录赊销
- 采购日记账 – 根据发票记录赊购
- 销售退回日记账 – 记录进货退回（发出的贷项通知单）
- 采购退回日记账 – 记录销货退回（收到的贷项通知单）
- 现金簿 – 合并银行和现金交易
- 零用现金簿 – 使用定额备用金制度记录小额现金支出
- 日记账 – 记录非常规交易、更正和期初分录
Totals from these day books are posted periodically to the general ledger and the receivables and payables ledgers. Understanding this process ensures you can trace any figure back to its source.
这些日记账的合计数会定期过账到总分类账以及应收和应付分类账。理解这一过程能确保你可以追溯任何数字至其来源。
4. Trial Balance and Correction of Errors | 试算平衡与错误更正
A trial balance is prepared by listing all ledger account balances at a given date. If total debits equal total credits, the books are said to be in balance. However, a balanced trial balance does not guarantee that errors do not exist.
试算平衡表通过列示某一日期所有分类账户余额编制而成。如果借方总额等于贷方总额，则账簿视为平衡。但试算平衡并不能保证没有错误存在。
Errors that do not affect the trial balance agreement are called 'errors not revealed by the trial balance' and include omission, commission, principle, original entry, reversal, and compensating errors. Errors that cause the trial balance to be unbalanced must be corrected using journal entries and a suspense account.
不影响试算平衡的错误被称为“试算平衡未发现的错误”，包括遗漏、账户误记、原则性错误、原始分录错误、反向分录和抵消错误。导致试算表不平衡的错误必须使用日记账分录和暂记账户进行更正。
You need to be able to identify errors from a given scenario, explain the correction needed, and update the profit and balance sheet figures accordingly. Suspense account questions are a staple of Edexcel exam papers.
你需要能够从给定情景中识别错误，解释所需的更正，并相应更新利润和资产负债表数字。暂记账户题目是 Edexcel 试卷中的常见内容。
5. Accruals, Prepayments and Other Adjustments | 预提、预付与其他调整
Under the accruals concept, expenses and income are recorded in the period they are incurred or earned, not when cash is exchanged. This requires year-end adjustments for accruals (amounts owing) and prepayments (amounts paid in advance).
根据权责发生制概念，费用和收入在其发生或赚取的期间记录，而不是在现金支付或收取时。这需要为预提（应付未付金额）和预付（预先支付的金额）进行年终调整。
- Accrued expense: charge the full amount to the income statement and show the unpaid portion as a current liability.
- Prepaid expense: remove the prepaid portion from the expense account and show it as a current asset.
- Accrued income: add the earned but not received amount to income and show as a current asset.
- Prepaid income (deferred income): reduce income by the amount not yet earned and show as a current liability.
- 预提费用：将全额计入利润表，并将未付部分列为流动负债。
- 预付费用：从费用账户中扣除预付部分，并将其列为流动资产。
- 应收收入（预提收入）：将已赚取但未收到的金额加至收入，并列为流动资产。
- 预收收入（递延收入）：将尚未赚取的金额从收入中减去，并列为流动负债。
These adjustments directly affect both the income statement and the statement of financial position. Always ensure your double-entry effects are correct and that ledger accounts are balanced after adjustments.
这些调整直接影响利润表和财务状况表。务必确保复式分录影响正确，并且调整后分类账户保持平衡。
6. Depreciation and Disposal of Non-Current Assets | 折旧与非流动资产的处置
Depreciation allocates the cost of a non-current asset over its useful life. The two main methods examined are the straight-line method and the reducing-balance method.
折旧将非流动资产的成本在其使用寿命内分摊。考试中两种主要方法是直线法和余额递减法。
Straight-line: Annual Depreciation = (Cost – Residual Value) / Useful Life
直线法：年折旧额 =（成本 – 残值）/ 使用寿命
Reducing-balance: Annual Depreciation = Net Book Value × Given Percentage
余额递减法：年折旧额 = 账面净值 × 给定百分比
When an asset is sold, a disposal account is used to calculate the profit or loss on disposal. The entries remove the asset’s cost and accumulated depreciation, record sales proceeds, and transfer the balance to the income statement.
当资产出售时，使用处置账户来计算处置利得或损失。分录要冲销资产的成本和累计折旧，记录销售收入，并将余额结转至利润表。
7. Irrecoverable Debts and Allowances for Receivables | 坏账与应收款项减值准备
Not all credit customers pay. When a debt is confirmed irrecoverable, it must be written off as an expense. Additionally, an allowance for doubtful debts is created to reflect potential future losses, applying the prudence concept.
并非所有赊账客户都会付款。当一笔债务确认无法收回时，必须作为费用注销。此外，需设立坏账准备以反映潜在的未来损失，这体现了审慎性概念。
- Irrecoverable debt: debit Irrecoverable Debts Expense, credit Trade Receivables.
- Increase in allowance: debit Irrecoverable Debts Expense, credit Allowance for Doubtful Debts.
- Decrease in allowance: debit Allowance for Doubtful Debts, credit Irrecoverable Debts Expense (or Income).
- 坏账：借记坏账费用，贷记应收账款。
- 坏账准备增加：借记坏账费用，贷记坏账准备。
- 坏账准备减少：借记坏账准备，贷记坏账费用（或收入）。
In the balance sheet, trade receivables are shown net of the allowance. The expense or income related to the allowance is presented in the income statement.
在资产负债表中，应收账款以扣除坏账准备后的净额列示。与准备相关的费用或收入在利润表中呈现。
8. Financial Statements for Sole Traders | 个体经营者财务报表
The two principal financial statements are the income statement (profit and loss account) and the statement of financial position (balance sheet). For a sole trader, these are prepared from the adjusted trial balance.
两个主要财务报表是利润表（损益表）和财务状况表（资产负债表）。对于个体经营者，这些报表根据调整后的试算平衡表编制。
The income statement matches revenues against expenses to compute gross profit and net profit for the period. A typical structure is:
利润表将收入与费用进行配比，计算出该期间的毛利润和净利润。典型结构如下：
Revenue – Cost of Sales = Gross Profit
收入 – 销售成本 = 毛利润
Gross Profit + Other Income – Expenses = Net Profit
毛利润 + 其他收入 – 费用 = 净利润
The statement of financial position follows the accounting equation and shows assets, liabilities, and capital at the period end. Non-current assets are recorded at net book value, while current assets include inventories, trade receivables, and prepayments.
财务状况表遵循会计等式，列示了期末的资产、负债和资本。非流动资产按账面净值列示，而流动资产包括存货、应收账款和预付账款。
9. Control Accounts and Bank Reconciliation | 控制账户与银行调节
Control accounts are a check on the accuracy of the sales and purchases ledgers. The receivables control account summarises all transactions with credit customers, while the payables control account does the same for suppliers.
控制账户用于核对销售和采购分类账的准确性。应收账款控制账户汇总了所有与赊账客户的交易，而应付账款控制账户则汇总了与供应商的交易。
A simple pro-forma includes opening balances, credit sales/purchases, receipts/payments, discounts, returns, and irrecoverable debts. The closing balance must match the total of individual accounts in the subsidiary ledger.
简易格式包括期初余额、赊销/赊购、收款/付款、折扣、退回和坏账。期末余额必须与明细分类账中各账户的合计余额一致。
Bank reconciliation compares the cash book balance with the bank statement. Differences arise from timing items such as unpresented cheques and lodgements not yet credited. You must be able to prepare an updated cash book and a bank reconciliation statement.
银行调节对比现金簿余额与银行对账单余额。差异源于时间性项目，如未兑现支票和尚未入账的存款。你必须能够编制更新后的现金簿和银行调节表。
10. Introduction to Incomplete Records | 不完整记录入门
When full double-entry records are not maintained, capital comparisons, control accounts, and mark-up/margin techniques are used to deduce missing figures. You should be able to calculate sales, purchases, and expenses from incomplete data.
当没有保留完整的复式记账记录时，可以使用资本比较、控制账户以及成本加成/销售毛利率法来推导缺失的数字。你应该能够从不完整的数据中计算出销售额、采购额和费用。
Net Profit = Closing Capital – Opening Capital + Drawings – Capital Introduced
净利润 = 期末资本 – 期初资本 + 提款 – 投入资本
Margin and mark-up relationships are also tested. If mark-up on cost is 25%, the margin on selling price is 20%. Applying these percentages to given figures helps reconstruct the income statement.
毛利率与成本加成率之间的关系也是考点。如果成本加成率为25%，则销售毛利率为20%。将这些百分比应用于已知数据有助于重建利润表。
