Every financial transaction your business makes needs to be recorded—and in the world of plain-text accounting, this starts with journal entries. If you're using Beancount, understanding journal entries is key to building accurate, auditable, and clean financial records.

This guide will walk you through:

• What a journal entry is
• Why journal entries matter
• How to write them in Beancount syntax
• How to use them effectively
• Examples of real-world transactions (client payments, purchases, loans, etc.)

🧾 What is a Journal Entry in Beancount?​

In Beancount, a journal entry is a dated transaction written in a human-readable plain-text format. Each entry follows the principles of double-entry accounting—you record where money comes from (credit) and where it goes (debit), ensuring your books always balance.

Example:

2024-06-01 * "Client payment for invoice #123"
  Assets:Bank:Checking     600.00 USD
  Income:Sales

• The * indicates a cleared transaction.
• The description shows context for the entry.
• Assets:Bank:Checking is debited.
• Income:Sales is credited (value implied).

Every entry lives inside a .beancount file—just a text file you can version, back up, and even edit in Vim or VSCode.

📒 Why Journal Entries Matter​

Journal entries are the atomic unit of your ledger.

They:

• Feed into your General Ledger and Account Balances
• Drive all reports: Income Statements, Balance Sheets, Cash Flows
• Let you trace every dollar, line by line, to its source

With the right tools, you'll see these transactions rendered in a UI—categorized, searchable, and filterable. But it all starts with that simple plain-text entry.

📚 How Double-Entry Works in Beancount​

Beancount enforces double-entry accounting. Every transaction must be balanced: total debits = total credits.

Quick rule:

• Debit assets and expenses (you gain cash or incur a cost)
• Credit income and liabilities (you earn money or take on debt)

Example – Office Supplies Purchase:

2024-06-02 * "Bought printer ink"
  Expenses:OfficeSupplies   100.00 USD
  Assets:Bank:Checking

🧠 Visualizing Entries​

Once you save, on the left side navigation of https://beancount.io/ledger/0/income_statement/ you will see ...

• Journal View: See transactions with search, tags, and filtering
• Account Filter Dropdown: See running balances and per-account entries
• Income Statement: Sum of your Income:* and Expenses:* accounts
• Balance Sheet: Your assets minus liabilities

Fava helps turn your raw Beancount entries into actionable reports—with zero database setup.

💡 Common Journal Entry Examples​

✅ You get paid by a client​

2024-06-05 * "Payment for invoice #456"
  Assets:Bank:Checking     1,200.00 USD
  Income:Consulting

Optional: If you use Accounts Receivable:

2024-05-20 * "Invoice #456 sent"
  Assets:AccountsReceivable   1,200.00 USD
  Income:Consulting

2024-06-05 * "Payment for invoice #456"
  Assets:Bank:Checking        1,200.00 USD
  Assets:AccountsReceivable  -1,200.00 USD

🖨️ You buy office supplies​

2024-06-07 * "Staples run"
  Expenses:OfficeSupplies     85.00 USD
  Assets:Bank:Checking

🏦 You make a loan payment​

Let’s say you pay $1,000, with $200 in interest and $800 toward principal:

2024-06-10 * "Loan repayment"
  Liabilities:Loan           -800.00 USD
  Expenses:LoanInterest       200.00 USD
  Assets:Bank:Checking      -1,000.00 USD

🔒 Closing Entries at Year-End​

To “close the books,” you typically transfer all Income and Expenses accounts into Equity.

2024-12-31 close Income:*
2024-12-31 close Expenses:*

Or, manually:

2024-12-31 * "Close books"
  Equity:RetainedEarnings     45,000.00 USD
  Income:Consulting          -45,000.00 USD

🛠️ Adjusting Entries​

If you're doing accrual accounting, you’ll want to add adjusting entries—for prepaid expenses, accrued revenue, etc.

Example: $100 monthly software subscription paid annually

2024-01-01 * "Annual software payment"
  Assets:Prepaid             1,200.00 USD
  Assets:Bank:Checking      -1,200.00 USD

2024-01-31 * "Monthly amortization"
  Expenses:Software           100.00 USD
  Assets:Prepaid             -100.00 USD

Automate with scripts or available Beancount tools.

Bookkeeping Basics You Can Actually Understand—and Own​

Managing your own books doesn’t have to mean spreadsheets, stress, or expensive software. Beancount gives you a minimalist, auditable, and powerful way to do bookkeeping using just plain text and a double-entry accounting system.

This guide is your complete introduction to getting your small business books in order with Beancount—with real examples and step-by-step direction.

🧾 What Is Beancount?​

Beancount is an open-source plain-text accounting system built around double-entry bookkeeping. You write your transactions in .beancount files and use tools like bean-doctor, bean-report, or Fava to analyze and visualize your books.

Here’s a basic transaction:

2025-06-01 * "Client Payment: Invoice #123"
  Assets:Bank:Business:Checking      1,200.00 USD
  Income:Consulting                 -1,200.00 USD

It's readable, scriptable, and version-controllable—perfect for business owners who want transparency and control.

📌 Why Bookkeeping Matters (and Why Beancount)​

• You need it for taxes
• You need it for clarity
• You need it for funding
• You need it to catch mistakes early

And with Beancount, you can do all of this with just a text editor and a few tools.

🪜 8 Steps to Start Doing Your Own Bookkeeping with Beancount​

1. Separate Business & Personal Finances​

Open a separate business checking account and credit card. Reflect that in Beancount:

2025-06-01 open Assets:Bank:Business:Checking USD
2025-06-01 open Liabilities:CreditCard:Business USD

This keeps your books clean and protects you legally (especially if you're an LLC or corporation).

2. Use Double-Entry Bookkeeping​

Every financial event affects two accounts. Beancount forces this balance by design:

2025-06-05 * "Web hosting payment"
  Expenses:Hosting                  15.00 USD
  Assets:Bank:Business:Checking    -15.00 USD

This guarantees mathematical integrity across your ledger.

3. Choose Cash or Accrual Basis​

• Cash Basis: Only record income/expenses when money is received/spent.
• Accrual Basis: Track obligations (Accounts Payable/Receivable).

Cash basis example:

2025-06-10 * "Client payment received"
  Assets:Bank:Business:Checking     800.00 USD
  Income:Sales                     -800.00 USD

Accrual basis example (invoice sent, then payment received):

2025-06-01 * "Invoice #2001 issued"
  Assets:AccountsReceivable         800.00 USD
  Income:Sales                     -800.00 USD

2025-06-15 * "Payment received for Invoice #2001"
  Assets:Bank:Business:Checking     800.00 USD
  Assets:AccountsReceivable        -800.00 USD

4. Set Up Your Chart of Accounts​

Define your categories clearly. A minimalist example:

2025-01-01 open Income:Sales USD
2025-01-01 open Expenses:Software USD
2025-01-01 open Expenses:Meals USD
2025-01-01 open Equity:Owner USD

Tailor these to your business. Keep it consistent and descriptive.

5. Categorize Transactions (with Metadata)​

Use metadata to track context. This helps with deductions, audits, and clarity.

2025-06-18 * "Team lunch after Q2 milestone"
  Expenses:Meals                    90.00 USD
  Assets:Bank:Business:Checking    -90.00 USD
  ; business_purpose: Q2 celebration
  ; attendees: Alice, Bob, Tian

Add tags or links to receipts:

  ; receipt: ./receipts/2025-06-18-lunch.jpg

6. Store Supporting Documents​

Use Dropbox, Google Drive, or a receipts/ folder. Then link them in Beancount like:

2025-06-02 * "Domain Renewal - GoDaddy"
  Expenses:Hosting                  20.00 USD
  Assets:Bank:Business:Checking    -20.00 USD
  ; receipt: ./receipts/domain-godaddy.pdf

Auditors and tax professionals will love you.

7. Organize for Deductions​

Mark deductible expenses clearly:

2025-06-03 * "Adobe Creative Cloud Subscription"
  Expenses:Software                60.00 USD
  Assets:Bank:Business:Checking   -60.00 USD
  ; deductible: true
  ; usage: 100% business

Use custom metadata or tags like #deductible to track potential write-offs.

8. Make It a Habit​

Create a workflow. Example:

# Weekly bookkeeping routine
git pull origin main
bean-extract transactions.csv >> ledger.beancount
bean-doctor ledger.beancount
bean-check ledger.beancount
fava ledger.beancount

Or just commit to a "Beancount Friday" and reconcile everything weekly.

💼 DIY or Hire Help?​

You can do it all yourself with Beancount. But even power users should:

• Consult a CPA during setup
• Hire an accountant at tax time if needed
• Use Fava for monthly reports

You get all the power of an accounting system without vendor lock-in or subscription fees.

🛠️ Recommended Tools for Beancount Users​

• Fava – beautiful web dashboard for Beancount files
• bean-doctor – health checks for your ledger
• bean-query – run SQL-like reports
• beancount-import / beanie – automated bank import
• Version control – use Git to track changes to your books

✅ Final Example: Complete Transaction Flow​

2025-06-20 * "Consulting payment from Acme Inc."
  Assets:Bank:Business:Checking        3,000.00 USD
  Income:Consulting                  -3,000.00 USD
  ; invoice: 2025-06-acme
  ; project: "Backend API redesign"

2025-06-21 * "Notion Pro Plan"
  Expenses:Software                     10.00 USD
  Assets:Bank:Business:Checking        -10.00 USD
  ; purpose: project documentation
  ; receipt: ./receipts/notion-june.pdf

In today's world, Environmental, Social, and Governance (ESG) metrics are no longer just buzzwords; they're essential indicators of a company's health and future viability. But how do you integrate these crucial sustainability insights with traditional financial accounting? Enter Beancount, an open-source, plain-text double-entry ledger that offers a surprisingly powerful and flexible solution for bridging this gap.

Imagine transforming your fragmented sustainability reporting into a streamlined, automated system that tracks everything from carbon emissions to supplier diversity, all within your existing financial workflow. Beancount makes this possible by treating ESG data as "first-class citizens alongside financial transactions."

Modeling ESG Data: The Beancount Way​

Beancount's inherent flexibility is its superpower when it comes to ESG. Instead of siloed spreadsheets, you can embed sustainability metrics directly into your financial structure using a few key techniques:

• Dedicated Accounts and Commodities: Think of your environmental footprint like another currency. You can create accounts like Metrics:Emissions:CO2e to track carbon emissions. These emissions can even be treated as a commodity (e.g., a unit of CO2 equivalent, tCO2e), allowing you to record specific quantities in your transactions. For instance, a flight purchase could credit an Emissions:CO2e account with +0.3 tCO2e alongside the monetary cost.
• Custom Metadata Tags: Beancount's key-value metadata is perfect for adding context. You can tag a transaction with CO2e: 0.3 t or Scope: 3 to denote its carbon impact or GHG Protocol scope. This links financial outlays directly to their environmental consequences, providing a richer, more complete picture.
• Structured Tags for Categories: Aligning with standards like the Greenhouse Gas Protocol (GHGP) is crucial. You can use consistent tags or account naming conventions, such as Metrics:Emissions:Scope1, Metrics:Emissions:Scope2, and Metrics:Emissions:Scope3 to easily categorize and report on direct, energy-related, and value chain emissions.

This adaptable approach means that as ESG standards evolve, you can adjust your ledger structure without a complete overhaul.

Beancount vs. Specialized ESG Tools: A Strategic Choice​

While dedicated ESG platforms like Persefoni or SAP Green Ledger offer highly automated, purpose-built solutions, Beancount presents a compelling alternative, particularly for those seeking transparency and control.

Beancount is a DIY powerhouse: It gives you unparalleled flexibility and transparency, making it ideal for individuals or technically savvy small organizations. You own your data completely, avoiding vendor lock-in.

Specialized tools offer turnkey solutions: They excel at automated data collection, built-in emission factor databases, and ready-made compliance reports, often at a higher cost and with less flexibility.

A hybrid approach is also viable: use Beancount for detailed internal tracking and reconciliation, then export summary data to an external platform for high-level stakeholder reporting.

Real-World Applications: ESG in Action with Beancount​

Beancount’s versatility makes it suitable for several key ESG use cases:

• Tracking Scope 3 Emissions: The most challenging emissions to track (from your value chain) can be integrated by linking supplier emissions data to purchase transactions. Beancount provides a clear audit trail for these complex figures, enabling better analysis and pinpointing data sources.
• Sustainability Audits and Assurance: Like financial data, ESG figures need to be verifiable. Beancount allows you to link each ESG entry to source documents (e.g., utility bills, third-party verification statements), providing a meticulous audit trail for transparency and assurance.
• EU CSRD/ESRS Compliance Reporting: For companies facing stringent regulations like CSRD, Beancount can serve as a central repository for quantitative disclosures. While it won't automatically format reports into XBRL, it provides the granular, auditable data needed to generate compliance-ready figures.
• Carbon Footprint Analysis & Management Accounting: Treat carbon as another dimension of management accounting. By allocating emissions to profit centers or product codes, you can calculate metrics like "emissions per dollar of revenue" and identify carbon hotspots, driving more informed sustainability decisions.

Best Practices for Your Beancount ESG Ledger​

To maximize the effectiveness of Beancount for ESG, consider these best practices:

1. Design a Clear Chart of Accounts for ESG: Structure your ESG accounts thoughtfully (e.g., Metrics:Emissions:Scope1:Fuel), just like your financial accounts.
2. Use Metadata Consistently: Leverage tags (e.g., Scope: 3, FactorSource: EPA2024) for consistent context and easier querying.
3. Balance Granularity with Manageability: Focus on material metrics to avoid overwhelming your ledger with unnecessary detail.
4. Automate with Caution: Use Python scripts for data import and validation, but ensure robust error checking and clear documentation of your automation processes.
5. Leverage Version Control: Use Git to track every change to your ledger, providing a transparent and auditable history of your ESG data.
6. Connect to Documents and Evidence: Link source files (e.g., PDFs of utility bills) to ledger entries for easy verification during audits.
7. Utilize Fava for Insights: Configure Fava to display custom ESG charts and reports, making your sustainability data actionable and accessible to non-technical stakeholders.
8. Stay Updated on Standards: ESG reporting is dynamic; be prepared to adapt your Beancount structure as new regulations and frameworks emerge.

The Future is Green, and Plain-Text​

While Beancount currently lacks native ESG intelligence or plug-and-play reporting, its open-source nature presents immense opportunities for enhancement. Community-driven plugins for carbon accounting, standardized ESG ledger templates, and better integration with emission factor APIs could significantly boost its capabilities.

As the corporate world increasingly embraces "green ledgers," Beancount stands ready as a flexible, transparent, and auditable solution. By integrating ESG data with the same rigor as financial data, Beancount empowers organizations to not only meet compliance demands but also drive meaningful sustainability initiatives.

Are you ready to bring your ESG data into the plain-text revolution?

Are you drowning in crypto transactions across multiple exchanges, struggling with DeFi complexity, or panicking about tax season? You're not alone. The cryptocurrency landscape has exploded from simple Bitcoin purchases to a sophisticated ecosystem of DeFi protocols, staking rewards, yield farming, and cross-chain activities that challenge traditional accounting methods.

Here's the harsh reality: every crypto transaction is potentially taxable, and the IRS is watching. Whether you're a casual Bitcoin holder or a DeFi power user managing positions across dozens of protocols, maintaining accurate financial records isn't optional—it's essential for compliance and financial clarity.

The problem? Traditional accounting software has limited native support for crypto's complexity. While tools like QuickBooks can handle crypto with additional plugins, and Excel can import blockchain data with scripts, most solutions require significant customization for comprehensive crypto accounting.

The solution? Beancount.io's plain-text accounting system built on the powerful open-source Beancount language. Important note: Beancount is an open-source double-entry accounting language created by Martin Blais, while Beancount.io is a commercial hosting service that provides a user-friendly interface and cloud infrastructure for Beancount. This guide covers both the underlying Beancount principles and how to use them effectively through the Beancount.io platform.

The Cryptocurrency Accounting Nightmare (And Why It's Getting Worse)​

Your Crypto Portfolio is Scattered Everywhere​

Let's be honest about your setup. You probably have:

• 3-5 different exchanges (Coinbase for easy buys, Binance for altcoins, Kraken for that one token...)
• Multiple wallets (MetaMask for DeFi, Ledger for long-term holds, that old wallet you forgot about...)
• DeFi positions across 10+ protocols (Uniswap, Compound, Aave, and whatever new yield farm caught your attention)
• Staking rewards trickling in from various validators
• Random airdrops appearing in your wallet like crypto Christmas presents

Each platform speaks a different language. Coinbase gives you a CSV that looks nothing like Binance's export. Uniswap doesn't even have exports. And don't get me started on tracking your DeFi positions across Layer 2 networks.

Transaction Types That Challenge Traditional Accounting​

Your crypto activities include transaction types that traditional accounting systems weren't originally designed to handle:

• Impermanent loss from liquidity providing (try explaining that to QuickBooks)
• Flash loans that borrow and repay millions in a single transaction
• Yield farming where you earn 5 different tokens for providing liquidity
• Cross-chain bridges that make assets disappear on one network and appear on another
• Staking derivatives like stETH that accrue value differently than the underlying asset
• DAO governance tokens that you received for using protocols

The Tax Compliance Minefield​

Here's what keeps crypto investors awake at night:

• Every single trade is taxable (yes, even that ETH-to-USDC swap)
• Cost basis tracking becomes impossible with hundreds of micro-transactions
• Staking rewards are income the moment you receive them (at fair market value)
• DeFi rewards are income even if you can't sell them yet
• The IRS wants Form 8949 with every single transaction listed
• Penalties are severe for getting it wrong

Traditional accounting software requires significant customization for this complexity. While solutions exist, they often require additional plugins, scripts, or manual processes to handle the full scope of cryptocurrency activities.

Enter Beancount.io: The Crypto Accounting Solution You've Been Waiting For​

What if I told you there's an accounting system designed for exactly this chaos? Beancount.io isn't just another accounting tool—it's a plain-text accounting revolution that handles cryptocurrency complexity like it was born for it.

Mastering Crypto Transactions: From Simple to Sophisticated​

Ready to see Beancount.io in action? Let's walk through real-world scenarios that would break other accounting systems but are handled elegantly here.

1. Your First Bitcoin Purchase (The Gateway Drug)​

Every crypto journey starts somewhere. Here's how to record that life-changing moment when you bought your first Bitcoin:

2024-01-15 * "Buy 0.5 BTC on Coinbase"
  Assets:Crypto:Coinbase:BTC     0.5 BTC {30000.00 USD}
  Assets:Crypto:Coinbase:USD  -15025.00 USD
  Expenses:Crypto:Fees:Trading    25.00 USD

2. Taking Profits (Or Cutting Losses) Like a Pro​

The moment of truth: selling your crypto. This is where most accounting systems fall apart, but Beancount.io shines with precise cost basis tracking:

2024-03-20 * "Sell 0.3 BTC on Coinbase"
  Assets:Crypto:Coinbase:BTC    -0.3 BTC {30000.00 USD}
  Assets:Crypto:Coinbase:USD   10470.00 USD
  Expenses:Crypto:Fees:Trading    30.00 USD
  Income:CapitalGains:Crypto   1440.00 USD  ; 10470 - (0.3 × 30000) - 30 = 1440

3. Staking Rewards: Earning While You Sleep​

Passive income at its finest. But remember, the IRS requires staking rewards to be reported as taxable income when received, based on fair market value at the time of receipt (per IRS Digital Assets guidance, 2024). While there is ongoing litigation (Jarrett v. United States), the current official position requires immediate reporting. Here's how to track them properly:

2024-02-01 * "ETH Staking Rewards"
  Assets:Staking:Ethereum:ETH      0.05 ETH {2500.00 USD}
  Income:Crypto:Staking:ETH      125.00 USD

4. DeFi Yield Farming: Where Things Get Spicy 🌶️​

Welcome to advanced DeFi accounting. DeFi yield farming involves complex multi-token transactions that require sophisticated tracking. Here's how to properly account for a Uniswap liquidity position:

; Initial liquidity provision
2024-01-10 * "Add liquidity to ETH-USDC pool"
  Assets:Crypto:Wallet:MetaMask:ETH    -10 ETH {2500.00 USD}
  Assets:Crypto:Wallet:MetaMask:USDC -25000 USDC {1.00 USD}
  Assets:DeFi:Uniswap:ETH-USDC-LP     100 UNI-V2-ETH-USDC {500.00 USD}

; Claiming rewards
2024-02-10 * "Claim Uniswap LP rewards"
  Assets:Crypto:Wallet:MetaMask:UNI    50 UNI {8.00 USD}
  Income:Crypto:DeFi:Yield           400.00 USD

5. Cross-Exchange Transfers​

Moving Bitcoin from Coinbase to Ledger wallet:

2024-01-20 * "Transfer BTC from Coinbase to Ledger"
  Assets:Crypto:Coinbase:BTC      -1.0 BTC {30000.00 USD}
  Assets:Crypto:Wallet:Ledger:BTC  0.9995 BTC {30000.00 USD}
  Expenses:Crypto:Fees:Withdrawal  0.0005 BTC {30000.00 USD}

Advanced Cryptocurrency Scenarios​

Margin Trading​

Recording leveraged positions:

; Opening a leveraged long position (borrowing BTC)
2024-02-15 * "Open 2x leveraged BTC position"
  Assets:Crypto:Binance:BTC-Margin      1.0 BTC {35000.00 USD}

Understanding Cryptocurrency Tax Requirements​

IRS Treatment of Cryptocurrency​

The IRS treats cryptocurrency as property, not currency, which creates specific tax implications:

• Every transaction is potentially taxable: Trading, selling, spending, or exchanging crypto
• Cost basis must be tracked: For every unit of cryptocurrency owned
• Holding period determines tax rate: Short-term vs. long-term capital gains
• Income recognition required: For mining, staking, airdrops, and DeFi rewards
• Detailed records mandatory: Transaction-level documentation for audits

Key Tax Forms for Cryptocurrency​

Form 1040 - Individual Income Tax Return​

• Line 1: Report crypto income (staking, mining, airdrops)
• Schedule 1: Additional income sources
• Digital Asset Question: Must answer "Yes" if you had crypto transactions

Form 8949 - Sales and Other Dispositions of Capital Assets​

• Part I: Short-term capital gains/losses (held ≤ 1 year)
• Part II: Long-term capital gains/losses (held > 1 year)
• Detailed transaction reporting: Date acquired, date sold, proceeds, cost basis

Schedule D - Capital Gains and Losses​

• Summary of Form 8949: Aggregated capital gains/losses
• Net capital gain/loss: Final calculation for tax liability

Tax Optimization Strategies​

1. Tax Loss Harvesting​

Systematically realize losses to offset gains:

; Identify losing positions
2024-12-15 * "Tax Loss Harvesting - Sell ADA at loss"
  purchase-date: "2024-06-01"
  purchase-price: "0.60 USD per ADA"
  sale-price: "0.45 USD per ADA"
  Assets:Crypto:Trading:Binance:ADA    -1000 ADA {0.60 USD}
  Assets:Crypto:Trading:Binance:USD     445.00 USD
  Expenses:Crypto:Fees:Deductible         5.00 USD
  Assets:Crypto:Trading:Binance:USD      -5.00 USD
  Expenses:CapitalLoss:ShortTerm       150.00 USD  ; Realized loss

2. Wash Sale Considerations​

While wash sale rules don't officially apply to crypto, avoid potential issues:

; Wait 31 days before repurchasing
2025-01-16 * "Repurchase ADA after wash sale period"
  wash-sale-safe: "31+ days elapsed"
  Assets:Crypto:Trading:Binance:ADA    1000 ADA {0.45 USD}
  Assets:Crypto:Trading:Binance:USD    -450.00 USD
  Expenses:Crypto:Fees:Deductible         5.00 USD
  Assets:Crypto:Trading:Binance:USD      -5.00 USD

3. Specific Identification Method​

Choose which lots to sell for optimal tax outcomes:

; High-cost basis lot for loss harvesting
2024-11-30 * "Sell high-cost ETH lot for tax loss"
  lot-selection: "specific-identification"
  cost-basis: "3500.00 USD per ETH"
  sale-price: "2400.00 USD per ETH"
  Assets:Crypto:Trading:Coinbase:ETH    -5 ETH {3500.00 USD}
  Assets:Crypto:Trading:Coinbase:USD  11950.00 USD
  Expenses:Crypto:Fees:Deductible        50.00 USD
  Assets:Crypto:Trading:Coinbase:USD    -50.00 USD
  Expenses:CapitalLoss:ShortTerm      5500.00 USD  ; Significant loss

4. Long-term vs Short-term Planning​

Strategically time sales for favorable tax treatment:

; Hold for long-term treatment
2024-12-20 * "BTC approaching long-term status"
  purchase-date: "2024-01-01"
  days-held: "354"
  long-term-date: "2025-01-02"
  note: "Hold 11 more days for long-term treatment"

Ready to master cryptocurrency tax compliance? Get started with Beancount.io and take control of your crypto tax obligations.

Decentralized Finance (DeFi) has revolutionized how we interact with financial services, offering unprecedented opportunities for yield generation, liquidity provision, and decentralized trading. However, with these opportunities comes the challenge of accurately tracking complex transactions for tax compliance and portfolio management.

Traditional accounting methods struggle with DeFi's unique characteristics: automated market makers, liquidity mining, impermanent loss, and multi-token rewards. This comprehensive guide shows you how to master DeFi accounting using Beancount.io's powerful plain-text accounting system.

Understanding DeFi Accounting Challenges​

The Complexity of DeFi Transactions​

DeFi protocols create accounting challenges that don't exist in traditional finance:

• Multi-token transactions: Single operations involving multiple cryptocurrencies
• Automated compounding: Rewards automatically reinvested
• Impermanent loss: Value changes due to price divergence in liquidity pools
• Gas fee optimization: Complex fee structures across different networks
• Protocol governance: Voting rights and governance token distributions
• Cross-protocol interactions: Transactions spanning multiple DeFi platforms

Tax Implications of DeFi Activities​

The IRS treats DeFi activities as taxable events:

• Liquidity provision: May trigger taxable events when depositing assets
• Yield farming rewards: Taxable as ordinary income at fair market value
• Impermanent loss: Potential tax implications when withdrawing from pools
• Governance tokens: Airdrops and rewards taxable as income
• Staking rewards: Taxable as income when received

Beancount version 3, released in mid-2024, marks a significant architectural evolution for the popular plain-text accounting tool. While it maintains backward compatibility for user ledger files, the underlying structure and accompanying tools have undergone substantial changes. Here’s a breakdown of what’s new in Beancount v3.

A More Modular and Streamlined Architecture​

The most significant change in Beancount v3 is the move to a more modular ecosystem. Several key functionalities that were previously bundled with the core have been spun off into separate, independent projects. This makes the core of Beancount leaner and allows for more focused development on individual components.

The key components that are now separate packages include:

• beanquery: The powerful SQL-like query tool for your ledger files is now in its own package.
• beangulp: This is the new home for the data importing framework, replacing the former beancount.ingest module.
• beanprice: A dedicated tool for fetching prices of commodities and stocks.

This separation means that users will need to install these packages in addition to beancount itself to retain the full functionality they were used to in version 2.

Changes to Command-Line Tools and Workflows​

Reflecting the new modular architecture, there are some notable changes to the command-line tools:

• bean-report is gone: This tool has been removed. Users are now encouraged to use bean-query (from the beanquery package) for their reporting needs.
• New Importer Workflow: The bean-extract and bean-identify commands have been removed from the core. The new approach with beangulp is script-based. Users will now create their own Python scripts to handle the importing of data from external sources like bank statements.

Syntax and Feature Enhancements​

While the core accounting principles remain the same, Beancount v3 introduces some welcome flexibility to its syntax:

• More Flexible Currency Codes: The previous restrictions on the length and characters for currency names have been relaxed. Single-character currency symbols are now supported.
• Expanded Transaction Flags: Users can now use any capital letter from A to Z as a flag for transactions, allowing for more granular categorization.

Importantly, these changes are backward-compatible, so your existing Beancount v2 ledger files will work without any modifications.

The C++ Rewrite and Performance​

One of the long-term goals for Beancount has been a rewrite of its performance-critical components in C++. While this work is ongoing, the initial release of Beancount v3 does not include the C++-based core. This means that for now, the performance of v3 is comparable to v2. The C++ code remains in a separate development branch for future integration.

Migrating from v2 to v3​

For most users, the migration from Beancount v2 to v3 is relatively straightforward:

1. Ledger Files: No changes are needed for your .beancount files.
2. Installation: You will need to install the new, separate packages like beanquery and beangulp using pip.
3. Importer Scripts: If you have custom importers, you will need to update them to use the new beangulp API. This mainly involves changing the base class your importers inherit from and adjusting some method signatures.
4. Fava: The popular web interface for Beancount, Fava, has been updated to be compatible with v3. Ensure you have the latest version of Fava for a seamless experience.

In essence, Beancount v3 is a foundational release that streamlines the project's architecture, making it more modular and easier to maintain and extend in the long run. While it requires some adjustments to user workflows, especially around data importing, it sets the stage for the future development of this powerful accounting tool.

Small business owners spend an average of 11 hours per month manually categorizing expenses - nearly three full workweeks annually devoted to data entry. A 2023 QuickBooks survey reveals that 68% of business owners rank expense tracking as their most frustrating bookkeeping task, yet only 15% have embraced automation solutions.

Plain text accounting, powered by tools like Beancount, offers a fresh approach to financial management. By combining transparent, programmable architecture with modern AI capabilities, businesses can achieve highly accurate expense categorization while maintaining full control over their data.

This guide will walk you through building an expense automation system tailored to your business's unique patterns. You'll learn why traditional software falls short, how to harness Beancount's plain text foundation, and practical steps for implementing adaptive machine learning models.

The Hidden Costs of Manual Expense Management​

Manual expense categorization drains more than just time—it undermines business potential. Consider the opportunity cost: those hours spent matching receipts to categories could instead fuel business growth, strengthen client relationships, or refine your offerings.

A recent Accounting Today survey found small business owners dedicate 10 hours weekly to bookkeeping tasks. Beyond the time sink, manual processes introduce risks. Take the case of a digital marketing agency that discovered their manual categorization had inflated travel expenses by 20%, distorting their financial planning and decision-making.

Poor financial management remains a leading cause of small business failure, according to the Small Business Administration. Misclassified expenses can mask profitability issues, overlook cost-saving opportunities, and create tax season headaches.

Beancount's Architecture: Where Simplicity Meets Power​

Beancount's plain-text foundation transforms financial data into code, making every transaction trackable and AI-ready. Unlike traditional software trapped in proprietary databases, Beancount's approach enables version control through tools like Git, creating an audit trail for every change.

This open architecture allows seamless integration with programming languages and AI tools. A digital marketing agency reported saving 12 monthly hours through custom scripts that automatically categorize transactions based on their specific business rules.

The plain text format ensures data remains accessible and portable—no vendor lock-in means businesses can adapt as technology evolves. This flexibility, combined with robust automation capabilities, creates a foundation for sophisticated financial management without sacrificing simplicity.

Creating Your Automation Pipeline​

Building an expense automation system with Beancount starts with organizing your financial data. Let's walk through a practical implementation using real examples.

1. Setting Up Your Beancount Structure​

First, establish your account structure and categories:

2025-01-01 open Assets:Business:Checking
2025-01-01 open Expenses:Office:Supplies
2025-01-01 open Expenses:Software:Subscriptions
2025-01-01 open Expenses:Marketing:Advertising
2025-01-01 open Liabilities:CreditCard

2. Creating Automation Rules​

Here's a Python script that demonstrates automatic categorization:

import pandas as pd
from datetime import datetime

def categorize_transaction(description, amount):
    rules = {
        'ADOBE': 'Expenses:Software:Subscriptions',
        'OFFICE DEPOT': 'Expenses:Office:Supplies',
        'FACEBOOK ADS': 'Expenses:Marketing:Advertising'
    }
    
    for vendor, category in rules.items():
        if vendor.lower() in description.lower():
            return category
    return 'Expenses:Uncategorized'

def generate_beancount_entry(row):
    date = row['date'].strftime('%Y-%m-%d')
    desc = row['description']
    amount = abs(float(row['amount']))
    category = categorize_transaction(desc, amount)
    
    return f'''
{date} * "{desc}"
    {category}                               {amount:.2f} USD
    Liabilities:CreditCard                  -{amount:.2f} USD
'''

3. Processing Transactions​

Here's how the automated entries look in your Beancount file:

2025-05-01 * "ADOBE CREATIVE CLOUD"
    Expenses:Software:Subscriptions            52.99 USD
    Liabilities:CreditCard                   -52.99 USD

2025-05-02 * "OFFICE DEPOT #1234 - PRINTER PAPER"
    Expenses:Office:Supplies                  45.67 USD
    Liabilities:CreditCard                   -45.67 USD

2025-05-03 * "FACEBOOK ADS #FB12345"
    Expenses:Marketing:Advertising           250.00 USD
    Liabilities:CreditCard                  -250.00 USD

Testing proves crucial—start with a subset of transactions to verify categorization accuracy. Regular execution through task schedulers can save 10+ hours monthly, freeing you to focus on strategic priorities.

Achieving High Accuracy Through Advanced Techniques​

Let's explore how to combine machine learning with pattern matching for precise categorization.

Pattern Matching with Regular Expressions​

import re

patterns = {
    r'(?i)aws.*cloud': 'Expenses:Cloud:AWS',
    r'(?i)(zoom|slack|notion).*subscription': 'Expenses:Software:Subscriptions',
    r'(?i)(uber|lyft|taxi)': 'Expenses:Travel:Transport',
    r'(?i)(marriott|hilton|airbnb)': 'Expenses:Travel:Accommodation'
}

def regex_categorize(description):
    for pattern, category in patterns.items():
        if re.search(pattern, description):
            return category
    return None
