1. Accounting Concepts | 会计概念
Accounting concepts are fundamental rules that underpin the preparation of financial statements. Key concepts include going concern, accruals, consistency, prudence, business entity, money measurement, historical cost, and substance over form.
会计概念是编制财务报表的基本规则。关键概念包括持续经营、权责发生制、一致性、谨慎性、企业主体、货币计量、历史成本以及实质重于形式。
The going concern concept assumes the business will continue operating in the foreseeable future; therefore assets are valued at cost less depreciation rather than break-up value.
持续经营概念假设企业将在可预见的未来继续经营；因此资产按成本减折旧计价，而非清算价值。
The accruals concept requires revenue and expenses to be recorded in the period they are earned or incurred, not when cash is received or paid. This leads to adjustments for prepayments and accruals.
权责发生制概念要求收入与费用在赚取或发生的期间记录，而非在现金收付时。这导致了预付与应计项目的调整。
Consistency demands that the same accounting methods are used from one period to the next, enabling meaningful comparison. Prudence means profits should not be anticipated and all foreseeable losses should be provided for.
一致性要求各期采用相同的会计方法，以便进行有意义的比较。谨慎性指不应预计利润，而应对所有可预见的损失计提准备。
The business entity concept treats the business as separate from its owner. Money measurement means only transactions that can be expressed in monetary terms are recorded. Historical cost records assets at original purchase price. Substance over form looks at economic reality rather than legal form.
企业主体概念将企业视为独立于其所有者的个体。货币计量指只有能以货币形式表述的交易才被记录。历史成本按原始购买价格记录资产。实质重于形式关注经济实质而非法律形式。
2. The Accounting Equation | 会计等式
The accounting equation states: Assets = Capital + Liabilities. This fundamental relationship must always hold true, as every transaction has a dual effect that keeps the equation in balance.
会计等式为：资产 = 资本 + 负债。这一基本关系必须始终成立，因为每笔交易都有双重影响，保持等式平衡。
Assets are resources controlled by the business, such as cash, inventory, and equipment. Capital is the owner’s investment plus accumulated profits less drawings. Liabilities are amounts owed to third parties, e.g. trade payables and loans.
资产是企业控制的资源，如现金、存货和设备。资本是所有者投资加上累计利润减去提款。负债是欠第三方的款项，例如应付账款和贷款。
For example, if the owner introduces £5,000 cash, assets (cash) increase by £5,000 and capital increases by £5,000. If the business takes a £2,000 loan, assets and liabilities both increase. The equation always remains balanced.
例如，若所有者投入 5,000 英镑现金，资产（现金）增加 5,000 英镑，资本增加 5,000 英镑。若企业获得 2,000 英镑贷款，资产和负债同时增加。等式始终保持平衡。
3. Double-Entry System | 复式记账系统
Double-entry bookkeeping records each transaction twice: a debit in one account and a credit in another. The total debits must equal total credits, ensuring the accounting equation is maintained.
复式记账法将每笔交易记录两次：一个账户记借方，另一个账户记贷方。借方总额必须等于贷方总额，从而维持会计等式。
A debit entry increases assets and expenses, while a credit entry increases liabilities, capital, and income. The traditional rule for asset and expense accounts is: debit to increase, credit to decrease. For liability, capital, and revenue accounts: credit to increase, debit to decrease.
借方记录增加资产和费用，贷方记录增加负债、资本和收入。对于资产与费用类账户，借记表示增加，贷记表示减少。对于负债、资本与收入类账户，贷记表示增加，借记表示减少。
The mnemonic DEAD CLIC is helpful: Debit Expenses, Assets, Drawings; Credit Liabilities, Income, Capital. All transactions must be analysed in terms of their effect on these categories before recording.
助记口诀 DEAD CLIC 很有用：借记费用、资产、提款；贷记负债、收入、资本。所有交易在记录前须按这些分类分析其影响。
For instance, a cash sale of £200: debit cash (asset increase), credit sales revenue (income increase). Purchase of stationery on credit for £50: debit stationery expense, credit trade payables.
例如，一笔 200 英镑现金销售：借记现金（资产增加），贷记销售收入（收入增加）。赊购 50 英镑文具：借记文具费用，贷记应付账款。
4. Source Documents | 原始凭证
Source documents provide evidence of financial transactions and are used to record entries in the books of prime entry. They include invoices, credit notes, debit notes, receipts, cheque counterfoils, bank statements, and petty cash vouchers.
原始凭证为财务交易提供证据，并用于在日记账中记录分录。它们包括发票、贷项通知单、借项通知单、收据、支票存根、银行对账单和备用金凭单。
An invoice is issued by the seller when goods are sold on credit, stating the quantity, price, and terms. A credit note is sent to a customer to reduce the amount owed, often for returned goods. A debit note may be issued to request a credit note from a supplier.
发票由卖方在赊销时开具，列明数量、价格和条款。贷项通知单用于减少客户欠款，通常因退货开出。借项通知单可向供应商发出以索取贷项通知单。
Receipts confirm cash payments received. Cheque counterfoils serve as a record of payments made by cheque. Bank statements are provided by the bank and show all transactions. Petty cash vouchers authorise small cash disbursements.
收据确认收到现金付款。支票存根作为签发支票的付款记录。银行对账单由银行提供，列示所有交易。备用金凭单用于批准小额现金支出。
5. Books of Prime Entry | 日记账
Books of prime entry are where transactions are first recorded from source documents before being posted to ledgers. They include the sales day book, purchases day book, returns inwards day book, returns outwards day book, cash book, petty cash book, and the general journal.
日记账是根据原始凭证首次记录交易的地方，之后再过账到分类账。它们包括销售日记账、采购日记账、销售退回日记账、采购退回日记账、现金账、备用金账和普通日记账。
The sales day book lists all credit sales from invoices. The purchases day book records all credit purchases. The returns inwards day book records goods returned by customers (sales returns). The returns outwards day book records goods returned to suppliers (purchases returns).
销售日记账列示所有赊销发票。采购日记账记录所有赊购交易。销售退回日记账记录客户退货（销售退回）。采购退回日记账记录向供应商退货（采购退回）。
The cash book acts as both a book of prime entry and a ledger account, recording all cash and bank transactions. The petty cash book records small cash expenses using the imprest system. The general journal is used for non-standard entries, such as year-end adjustments, and must include a narrative.
现金账既是日记账也是分类账，记录所有现金和银行交易。备用金账使用定额制度记录小额现金开支。普通日记账用于非标准分录，如年末调整，必须包含摘要说明。
6. Ledgers and Trial Balance | 分类账与试算平衡表
Ledgers are the books containing individual accounts. The main ledgers are the sales ledger (for trade receivables), purchases ledger (for trade payables), and the general ledger (for all other accounts such as assets, expenses, capital, and income).
分类账是包含单个账户的账簿。主要分类账有销售分类账（记录应收账款）、采购分类账（记录应付账款）和总分类账（记录所有其他账户，如资产、费用、资本和收入）。
After posting transactions from the books of prime entry to the ledgers, a trial balance is prepared. The trial balance is a list of all the ledger balances at a particular date, with debit balances in one column and credit balances in another.
从日记账将交易过账至分类账后，需编制试算平衡表。试算平衡表是在特定日期列示所有分类账余额的列表，借方余额在一栏，贷方余额在另一栏。
The main purpose of the trial balance is to check the arithmetic accuracy of the double-entry records; total debits should equal total credits. It also helps in preparing financial statements.
试算平衡表的主要目的是检查复式记账的算术准确性；借方总额应等于贷方总额。它还有助于编制财务报表。
However, a balanced trial balance does not guarantee there are no errors. Errors of omission, commission, principle, complete reversal, original entry, and compensating errors may still exist.
然而，试算平衡表平衡并不能保证没有错误。遗漏错误、记错账户、原则性错误、完全反向记账、原始入账错误和抵销性错误仍可能存在。
7. Income Statement | 利润表
The income statement shows the financial performance of a business over a period. For a sole trader, it calculates gross profit and profit for the year.
利润表反映企业在一定期间内的财务业绩。对于个体经营者，它用以计算毛利和年度利润。
Revenue (sales) less sales returns gives net sales. Cost of sales is calculated as: opening inventory + purchases – purchases returns + carriage inwards – closing inventory. Net sales minus cost of sales equals gross profit.
销售收入减去销售退回得出销售净额。销售成本计算方式为：期初存货 + 采购 – 采购退回 + 进货运费 – 期末存货。销售净额减去销售成本等于毛利。
Gross profit minus expenses (e.g. rent, wages, depreciation, bad debts) gives profit for the year. Other income, such as commission receivable, is added. The income statement uses the accruals basis, so adjustments for prepayments and accruals are incorporated.
毛利减去费用（如租金、工资、折旧、坏账）得出年度利润。其他收益，如应收佣金，应予加计。利润表基于权责发生制，因此需纳入预付和应计调整。
| Income Statement (extract) | |
|---|---|
| Revenue | £XX |
| Cost of sales | (£XX) |
| Gross profit | £XX |
| Expenses | (£XX) |
| Profit for the year | £XX |
8. Statement of Financial Position | 资产负债表
The statement of financial position shows the assets, liabilities, and capital of a business at a specific point in time. It follows the accounting equation: net assets = capital.
资产负债表显示企业在某一特定时点的资产、负债和资本。它遵循会计等式：净资产 = 资本。
Non-current assets are held for long-term use, e.g. machinery, vehicles, and premises. They are shown at cost less accumulated depreciation (carrying amount).
非流动资产为长期持有使用，如机器、车辆和房产。它们按成本减累计折旧后的净值列示。
Current assets are expected to be turned into cash within one year, including inventory, trade receivables (less allowance for doubtful debts), prepayments, and cash at bank and in hand.
流动资产预期在一年内变现，包括存货、应收账款（减去坏账准备）、预付款项以及银行存款与库存现金。
Current liabilities are payable within one year, such as trade payables, accruals, and bank overdraft. Non-current liabilities are due after more than one year, e.g. long-term loans.
流动负债在一年内需偿付，如应付账款、应计费用和银行透支。非流动负债在一年以上到期，如长期贷款。
Capital is calculated as opening capital + profit for the year – drawings. The total assets minus total liabilities should equal the closing capital.
资本的计算为期初资本 + 年度利润 – 提款。总资产减去总负债应等于期末资本。
9. Depreciation | 折旧
Depreciation is the allocation of a non-current asset’s cost over its useful life. It follows the accruals concept and prudence. The two common methods are straight-line and reducing balance.
折旧是将非流动资产成本在其使用年限内进行分摊。它遵循权责发生制与谨慎性原则。常用方法有直线法和余额递减法。
Straight-line method: annual depreciation charge = (cost – residual value) / useful life. The same amount is charged each year.
直线法：年折旧额 = (成本 – 残值) / 使用年限。每年计提金额相同。
Reducing balance method applies a fixed percentage to the net book value (cost minus accumulated depreciation). This results in higher depreciation in early years.
余额递减法按固定百分比乘以账面净值（成本减累计折旧）计算。这导致早期折旧额较高。
The double-entry for depreciation: debit depreciation expense (income statement), credit accumulated depreciation (statement of financial position). Accumulated depreciation is a contra-asset account, reducing the asset’s carrying amount.
折旧的复式分录为：借记折旧费用（利润表），贷记累计折旧（资产负债表）。累计折旧是资产备抵账户，减少资产的账面价值。
When an asset is sold, any difference between sale proceeds and carrying amount is recorded as a profit or loss on disposal in the income statement.
当资产出售时，出售收入与账面价值之间的差额作为处置损益记入利润表。
10. Accruals and Prepayments | 应计与预付
Accruals (accrued expenses) are expenses incurred but not yet paid by the period end. They must be added to the relevant expense in the income statement and shown as a current liability.
应计项目（应计费用）是截至期末已发生但尚未支付的费用。它们必须加入利润表中相关费用，并作为流动负债列示。
Prepayments (prepaid expenses) are expenses paid in advance for a future period. They are deducted from the expense in the income statement and shown as a current asset.
预付项目（预付费用）是为未来期间预先支付的费用。它们从利润表费用中扣除，并作为流动资产列示。
For example, rent of £1,200 per year is paid. At the year-end, £300 may be prepaid; this amount is excluded from the income statement and shown as a prepayment asset. If rent of £200 is owing, it is added to rent expense and shown as an accrual liability.
例如，年租金 1,200 英镑。年末可能有 300 英镑预付；该金额不计入利润表，而作为预付资产列示。若欠付租金 200 英镑，则加至租金费用并作为应计负债列示。
The adjusting entries: for an accrual, debit expense, credit accruals. For a prepayment, debit prepayments, credit expense. These ensure the matching principle is applied.
调整分录：对于应计，借记费用，贷记应计项目。对于预付，借记预付项目，贷记费用。这确保了配比原则的运用。
11. Bad Debts and Allowance for Doubtful Debts | 坏账与坏账准备
A bad debt arises when a trade receivable is deemed irrecoverable. The double-entry to write off a bad debt is: debit bad debts expense, credit trade receivables. This removes the debt from the statement of financial position.
当应收账款被认定无法收回时即产生坏账。注销坏账的分录为：借记坏账费用，贷记应收账款。这将该债务从资产负债表中移除。
An allowance for doubtful debts is an estimate of future bad debts, based on prudence. It can be specific (on particular customers) or general (a percentage of trade receivables).
坏账准备是基于谨慎性原则对未来坏账的估计。它可以是特定准备（针对特定客户）或一般准备（按应收账款百分比计提）。
The adjusting entry for creation or increase: debit bad debts expense, credit allowance for doubtful debts. A decrease in allowance is credited to income (reduction in expense). In the statement of financial position, trade receivables are shown net of the allowance.
计提或增加准备的分录：借记坏账费用，贷记坏账准备。准备减少则贷记收益（费用减少）。资产负债表中，应收账款以扣除坏账准备后的净额列示。
Recovery of a debt previously written off: debit cash, credit bad debts recovered (income). If an allowance is then adjusted, the relevant entries should be made.
收回以前注销的债务：借记现金，贷记坏账收回（收益）。若需调整准备，应做相应分录。
12. Bank Reconciliation and Control Accounts | 银行对账与控制账户
A bank reconciliation statement matches the cash book balance with the bank statement balance, identifying timing differences and errors. The cash book should be updated for items appearing on the bank statement but not yet recorded, such as bank charges, direct debits, and standing orders.
银行调节表核对现金账余额与银行对账单余额，找出时间差异与错误。现金账应根据银行对账单上已出现但尚未记录的项目进行更新，如银行手续费、直接借记和自动转账。
After updating, a bank reconciliation is prepared starting from the updated cash book balance or balance per bank statement. Common adjustments include unpresented cheques (deducted from bank statement balance) and outstanding lodgements
