Bookkeeping Basics

基础簿记指南

Overview

概述

Bookkeeping tracks where money comes from and where it goes. Most solopreneurs hate bookkeeping, so they avoid it — then face chaos at tax time or when applying for loans. This playbook gives you a simple system: minimal time, maximum clarity. Disclaimer: This is educational content, not professional accounting advice. Consult a CPA for complex situations.

簿记的作用是追踪资金的流入与流出。大多数个体经营者都讨厌簿记工作，因此会刻意回避——直到报税季或申请贷款时陷入混乱。本指南提供一套简单的体系：耗时最少，清晰度最高。免责声明：本内容为教育性质，并非专业会计建议。复杂情况请咨询注册会计师（CPA）。

Step 1: Choose Your Accounting Software

步骤1：选择合适的会计软件

Don't use spreadsheets. Use accounting software. It automates most of the work and keeps you compliant.

Software comparison:

Software	Best For	Pricing	Learning Curve	Features
Wave	Freelancers, very small businesses	Free (pay for payments/payroll)	Easy	Basic invoicing, expense tracking, reports
QuickBooks Online	Most solopreneurs, scaling businesses	$15-50/month	Medium	Full accounting, invoicing, tax reports, integrations
FreshBooks	Service businesses, invoicing-heavy	$17-55/month	Easy	Invoicing, time tracking, expense tracking
Xero	International businesses, contractors	$13-70/month	Medium	Full accounting, multi-currency, payroll

Selection guide:

Just starting, no revenue yet → Wave (free)
Revenue < $50K/year → Wave or FreshBooks
Revenue $50K-250K/year → QuickBooks Online
International clients or contractors → Xero

Recommendation: Start with Wave (free). Upgrade to QuickBooks when you hit $50K revenue or need more features.

不要使用电子表格，改用会计软件。它能自动化大部分工作，还能确保合规性。

软件对比：

软件	适用人群	定价	学习难度	功能
Wave	自由职业者、微型企业	免费（支付/薪资服务需付费）	简单	基础发票开具、费用追踪、报表生成
QuickBooks Online	多数个体经营者、成长型企业	15-50美元/月	中等	完整会计功能、发票开具、税务报表、集成能力
FreshBooks	服务型企业、发票需求频繁的用户	17-55美元/月	简单	发票开具、时间追踪、费用追踪
Xero	跨国企业、承包商	13-70美元/月	中等	完整会计功能、多币种支持、薪资服务

选择指南：

刚起步、尚无营收 → Wave（免费）
年营收<5万美元 → Wave或FreshBooks
年营收5万-25万美元 → QuickBooks Online
有国际客户或承包商 → Xero

推荐建议： 从Wave（免费）开始。当营收达到5万美元或需要更多功能时，升级到QuickBooks。

Step 2: Set Up Your Chart of Accounts

步骤2：设置会计科目表

A chart of accounts is a list of categories for organizing income and expenses. Most software comes with defaults — use them unless you have a specific reason to customize.

Basic chart of accounts (solopreneur):

会计科目表是用于分类收支的类别列表。大多数软件都自带默认模板——除非有特殊需求，否则直接使用即可。

个体经营者基础会计科目表：

INCOME CATEGORIES:

收入类别：

Sales Revenue (product/service sales)
Consulting Revenue
Other Income (interest, refunds, etc.)

销售收入（产品/服务销售）
咨询收入
其他收入（利息、退款等）

EXPENSE CATEGORIES:

支出类别：

Cost of Goods Sold (COGS): Direct costs to deliver your product/service (if applicable)
Operating Expenses:
- Advertising / Marketing
- Software / Tools / Subscriptions
- Contractor Payments
- Office Supplies
- Professional Services (lawyer, accountant)
- Travel / Meals (business-related)
- Insurance
- Bank Fees / Merchant Fees
- Home Office Deduction (if applicable)
- Utilities (if home office)
- Other Expenses

Rule: Don't over-categorize. 10-15 categories max. Too many creates confusion. Too few makes tax prep hard.

销货成本（COGS）： 交付产品/服务的直接成本（如适用）
运营费用：
- 广告/营销
- 软件/工具/订阅服务
- 承包商报酬
- 办公用品
- 专业服务（律师、会计师）
- 差旅/餐饮（商务相关）
- 保险
- 银行手续费/商户手续费
- 家庭办公抵扣（如适用）
- 水电费（如为家庭办公）
- 其他费用

规则： 不要过度分类。最多10-15个类别。类别过多会造成混乱，过少则会增加报税难度。

Step 3: Track Every Transaction

步骤3：追踪每一笔交易

Every dollar in and every dollar out must be recorded. No exceptions.

Income tracking:

Record every payment received (invoice, client name, date, amount)
Use invoicing software (Wave, QuickBooks, FreshBooks) to generate invoices and track payments automatically
For cash payments, create manual invoices or receipts

Expense tracking:

Connect your business bank account and credit card to your accounting software (auto-imports transactions)
Categorize each expense when it imports (software learns patterns over time)
Save receipts (digital copies, not paper — use apps like Expensify or Shoeboxed, or just your phone camera)

Receipt rules (IRS):

Keep receipts for expenses > $75
Keep receipts for ALL meals, travel, and entertainment (even under $75)
Store digitally (cloud storage, accounting software, or receipt app)
Retain for 7 years (IRS audit window)

Bank/credit card reconciliation (monthly): Reconciliation = matching your accounting software records to your actual bank statements.

How to reconcile (15-30 min/month):

Download bank statement for the month
Open your accounting software's reconciliation tool
Check off each transaction in software that matches the bank statement
Investigate any mismatches (missing transactions, duplicate entries)
Mark reconciliation as complete

Why this matters: Catches errors, fraud, or missed transactions. If software balance ≠ bank balance, something's wrong.

每一笔资金的流入和流出都必须记录，无一例外。

收入追踪：

记录每一笔到账款项（发票、客户名称、日期、金额）
使用发票软件（Wave、QuickBooks、FreshBooks）自动生成发票并追踪付款
对于现金付款，创建手动发票或收据

支出追踪：

将企业银行账户和信用卡与会计软件关联（自动导入交易记录）
交易记录导入后进行分类（软件会随着时间推移学习你的分类模式）
保存收据（电子副本，不要纸质——使用Expensify或Shoeboxed等应用，或直接用手机相机拍摄）

IRS收据规则：

保留金额超过75美元的支出收据
保留所有餐饮、差旅和娱乐支出的收据（即使金额低于75美元）
数字化存储（云存储、会计软件或收据管理应用）
保留7年（IRS审计窗口期）

银行/信用卡月度对账： 对账是指将会计软件记录与实际银行对账单进行匹配。

对账步骤（每月15-30分钟）：

下载当月银行对账单
打开会计软件的对账工具
勾选软件中与银行对账单匹配的每一笔交易
调查任何不匹配项（缺失交易、重复录入等）
标记对账完成

重要性： 发现错误、欺诈或遗漏的交易。如果软件余额与银行余额不符，说明存在问题。

Step 4: Separate Business and Personal Finances

步骤4：分离企业与个人财务

NEVER mix business and personal money. It's the #1 bookkeeping mistake.

Why separation matters:

Simplifies bookkeeping (business account = business transactions only)
Protects your LLC liability protection (mixing funds pierces the corporate veil)
Makes taxes easier (clear business expenses vs personal)
Looks professional to clients, lenders, investors

How to separate:

Open a business bank account (use your EIN, not SSN)
Get a business credit card
Pay yourself a salary or owner's draw (transfer from business to personal account on a schedule)
Pay all business expenses from business account ONLY
Pay all personal expenses from personal account ONLY

If you accidentally pay a personal expense from business account:

Record it as "Owner's Draw" or "Personal Expense" in your bookkeeping
Don't try to deduct it on taxes (it's not a business expense)

绝对不要混用企业和个人资金。这是簿记的头号错误。

分离的重要性：

简化簿记（企业账户仅用于企业交易）
保护LLC的有限责任保护（混用资金会打破公司面纱）
简化报税流程（清晰区分企业支出与个人支出）
给客户、贷款方、投资者留下专业印象

分离方法：

开设企业银行账户（使用EIN，而非SSN）
申请企业信用卡
给自己发放薪水或业主提款（定期从企业账户转账到个人账户）
所有企业支出仅从企业账户支付
所有个人支出仅从个人账户支付

如果不小心用企业账户支付了个人支出：

在簿记中记录为“业主提款”或“个人支出”
不要在报税时抵扣该支出（这不属于企业支出）

Step 5: Understand Basic Financial Statements

步骤5：了解基础财务报表

Your accounting software generates these automatically. You should review them monthly.

会计软件会自动生成这些报表。你应该每月进行查看。

Profit & Loss (P&L) / Income Statement

损益表（P&L）

Shows: Revenue - Expenses = Profit (or Loss)

What it tells you: Are you making money? Which expense categories are highest?

Example:

Revenue:              $10,000
Expenses:
  Marketing:          $2,000
  Software:           $500
  Contractor:         $3,000
  Other:              $1,000
Total Expenses:       $6,500
Net Profit:           $3,500

How to use it:

Compare month-over-month (are you growing?)
Identify expense trends (is one category ballooning?)
Calculate profit margin (Net Profit / Revenue = 35% in example above — healthy is 20-50%)

展示：收入 - 支出 = 利润（或亏损）

作用： 你是否盈利？哪类支出占比最高？

示例：

Revenue:              $10,000
Expenses:
  Marketing:          $2,000
  Software:           $500
  Contractor:         $3,000
  Other:              $1,000
Total Expenses:       $6,500
Net Profit:           $3,500

使用方法：

逐月对比（业务是否在增长？）
识别支出趋势（某类支出是否在激增？）
计算利润率（净利润/收入=示例中的35%——健康范围为20-50%）

Balance Sheet

资产负债表

Shows: Assets = Liabilities + Equity

What it tells you: What you own (assets), what you owe (liabilities), and what's left over (equity/net worth).

Most solopreneurs can ignore this unless applying for a loan or raising funding.

展示：资产 = 负债 + 所有者权益

作用： 你拥有什么（资产），你欠什么（负债），以及剩余价值（权益/净资产）。

大多数个体经营者可以忽略此报表，除非申请贷款或筹集资金。

Cash Flow Statement

现金流量表

Shows: Cash in - Cash out = Net cash flow

What it tells you: Are you running out of cash? (even profitable businesses can have cash flow problems if customers pay late)

How to use it:

Track cash balance over time
Predict cash shortages (if expenses > revenue for next 2-3 months)
Plan for large purchases or dry spells

展示：现金流入 - 现金流出 = 净现金流

作用： 你是否会出现现金短缺？（即使盈利的企业也可能因客户付款延迟而面临现金流问题）

使用方法：

追踪现金余额变化
预测现金短缺（如果未来2-3个月支出超过收入）
规划大额采购或业务淡季

Step 6: Prepare for Tax Time

步骤6：为报税季做准备

Good bookkeeping makes tax prep fast and cheap. Bad bookkeeping means expensive CPA hours or IRS penalties.

Tax prep checklist (do this all year, not just at tax time):

Categorize every transaction monthly (don't wait until December)
Save receipts for deductible expenses
Track mileage if you drive for business (apps: MileIQ, Everlance)
Set aside 25-30% of revenue for taxes (transfer to separate savings account)
Generate a P&L at year-end (December 31)
Prepare a summary of all income and expenses by category
Hand off to your CPA or tax software (TurboTax, TaxAct)

Common deductible expenses (U.S.):

Home office (if you have dedicated workspace)
Software and subscriptions
Contractor payments
Marketing and advertising
Professional services (lawyer, accountant)
Business travel and meals (50% of meals, 100% of travel)
Equipment and tools
Business insurance
Bank and merchant fees

Non-deductible (can't write off):

Personal expenses
Commuting (home to office — but client visits are deductible)
Clothing (unless it's a uniform or specialized work gear)
Entertaining clients (used to be 50% deductible, now 0% as of 2021 — check current rules)

Rule: When in doubt, ask your CPA. Don't guess on deductions.

良好的簿记能让报税流程快速且低成本。糟糕的簿记则意味着昂贵的会计师服务费或IRS罚款。

报税准备清单（全年执行，不要等到报税季才做）：

每月对所有交易进行分类（不要等到12月）
保存可抵扣支出的收据
如果因商务驾车，追踪里程（应用：MileIQ、Everlance）
预留营收的25-30%用于缴税（转账到单独的储蓄账户）
年末（12月31日）生成损益表
按类别整理所有收入和支出的汇总表
交给你的CPA或报税软件（TurboTax、TaxAct）

美国常见可抵扣支出：

家庭办公（如果有专属工作空间）
软件和订阅服务
承包商报酬
营销和广告
专业服务（律师、会计师）
商务差旅和餐饮（餐饮可抵扣50%，差旅可全额抵扣）
设备和工具
企业保险
银行和商户手续费

不可抵扣支出：

个人支出
通勤费用（家到办公室——但拜访客户的行程可抵扣）
服装（除非是制服或专业工作装备）
客户招待（2021年起从可抵扣50%变为0%——请查阅最新规定）

规则： 如有疑问，请咨询CPA。不要自行猜测抵扣项。

Step 7: Monthly Bookkeeping Routine (30-60 min/month)

步骤7：月度簿记例行工作（每月30-60分钟）

Consistency prevents end-of-year chaos. Do these tasks monthly:

Monthly bookkeeping checklist:

Reconcile bank and credit card accounts (match software to statements)
Categorize any uncategorized transactions
Review P&L (revenue vs expenses, profit margin)
Send outstanding invoices (if clients haven't paid)
Follow up on overdue invoices (Net-30 past due? Send reminder)
Pay bills due this month (don't miss deadlines or you'll pay late fees)
Set aside taxes (transfer 25-30% of profit to tax savings account)
Check cash flow (will you run out of cash in next 2-3 months? If yes, plan ahead)

Time required: 30 min if your bookkeeping is current. 3 hours if you've been ignoring it.

Rule: Do this monthly. Don't wait until tax season.

坚持例行工作可避免年末混乱。每月完成以下任务：

月度簿记清单：

对账银行和信用卡账户（匹配软件记录与对账单）
分类未归类的交易
查看损益表（收入vs支出、利润率）
发送未结清的发票（如果客户尚未付款）
跟进逾期发票（超过30天未付？发送提醒）
支付本月到期账单（不要错过截止日期，否则会产生滞纳金）
预留缴税资金（将利润的25-30%转账到缴税储蓄账户）
检查现金流（未来2-3个月是否会出现现金短缺？如果是，提前规划）

所需时间： 如果簿记工作及时更新，只需30分钟。如果一直拖延，则需要3小时。

规则： 每月完成这些工作，不要等到报税季。

Step 8: When to Hire a Bookkeeper or CPA

步骤8：何时聘请簿记员或CPA

DIY bookkeeping works if:

Revenue < $100K/year
Simple business model (no inventory, payroll, or complex transactions)
You can commit 1 hour/month to bookkeeping

Hire a bookkeeper if:

Revenue > $100K/year
Complex transactions (inventory, multiple revenue streams, many contractors)
You hate bookkeeping and keep procrastinating

Cost: Virtual bookkeeper = $200-500/month. Worth it if it saves you 5+ hours/month.

Hire a CPA (tax accountant) if:

Revenue > $50K/year (DIY taxes become risky)
Complex tax situation (multiple LLCs, S-Corp election, international clients)
You want to maximize deductions and minimize tax liability

Cost: CPA = $500-2,000/year for tax prep. More if you need year-round advice.

Rule: DIY bookkeeping is fine. DIY taxes past $50K revenue is risky. Hire a CPA.

适合自行处理簿记的情况：

年营收<10万美元
业务模式简单（无库存、薪资或复杂交易）
每月能抽出1小时处理簿记

适合聘请簿记员的情况：

年营收>10万美元
存在复杂交易（库存、多收入来源、大量承包商）
你讨厌簿记工作且一直拖延

成本： 虚拟簿记员每月200-500美元。如果能为你每月节省5小时以上的时间，就是值得的。

适合聘请CPA（税务会计师）的情况：

年营收>5万美元（自行报税风险升高）
复杂税务情况（多个LLC、S公司选举、国际客户）
你想最大化抵扣额并最小化税负

成本： CPA报税服务每年500-2000美元。如果需要全年咨询服务，费用会更高。

规则： 自行处理簿记是可行的。年营收超过5万美元后自行报税存在风险，建议聘请CPA。

Bookkeeping Mistakes to Avoid

需避免的簿记错误

Not tracking expenses. Every dollar counts at tax time. Missing receipts = higher taxes.
Mixing personal and business finances. Creates a mess. Separate accounts from day one.
Not reconciling monthly. Errors compound. Reconcile monthly or you'll regret it at year-end.
Waiting until tax season to organize. Bookkeeping in December is painful. Do it monthly.
Not setting aside money for taxes. Quarterly taxes sneak up on you. Save 25-30% of profit consistently.
Guessing at expense categories. If unsure, ask a CPA. Wrong categorization = IRS audit risk.

未追踪支出： 报税时每一分钱都很重要。丢失收据会导致税负增加。
混用企业与个人财务： 会造成混乱。从第一天起就分离账户。
未每月对账： 错误会不断累积。每月对账，否则年末会后悔。
等到报税季才整理： 12月处理簿记工作非常痛苦。每月完成。
未预留缴税资金： 季度缴税会突然到来。持续预留利润的25-30%。
猜测支出类别： 如有疑问，请咨询CPA。错误分类会增加IRS审计风险。
