In today's blog post, we will be breaking down a Beancount ledger for businesses, which will help you understand the intricacies of this plain text double-entry accounting system.

Deconstructing a Beancount Ledger: A Case Study for Business Accounting

Let's start with the code first:

1970-01-01 open Assets:Bank:Mercury
1970-01-01 open Assets:Crypto
 
1970-01-01 open Equity:Bank:Chase
 
1970-01-01 open Income:Stripe
1970-01-01 open Income:Crypto:ETH
 
1970-01-01 open Expenses:COGS
1970-01-01 open Expenses:COGS:Contabo
1970-01-01 open Expenses:COGS:AmazonWebServices
 
1970-01-01 open Expenses:BusinessExpenses
1970-01-01 open Expenses:BusinessExpenses:ChatGPT
 
2023-05-14 * "CONTABO.COM" "Mercury Checking ••1234"
  Expenses:COGS:Contabo                               17.49 USD
  Assets:Bank:Mercury                                -17.49 USD
 
2023-05-11 * "Amazon Web Services" "Mercury Checking ••1234"
  Expenses:COGS:AmazonWebServices                  14490.33 USD
  Assets:Bank:Mercury                             -14490.33 USD
 
2023-03-01 * "STRIPE" "Mercury Checking ••1234"
  Income:Stripe                                   -21230.75 USD
  Assets:Bank:Mercury                              21230.75 USD
 
2023-05-18 * "customer_182734" "0x5190E84918FD67706A9DFDb337d5744dF4EE5f3f"
  Assets:Crypto                                         -19 ETH {1,856.20 USD}
  Income:Crypto:ETH                                      19 ETH @@ 35267.8 USD

Understanding the Code

  1. Opening Accounts: The code starts by opening a series of accounts on 1970-01-01. These include a mix of asset accounts (Assets:Bank:Mercury and Assets:Crypto), an equity account (Equity:Bank:Chase), income accounts (Income:Stripe and Income:Crypto:ETH), and expense accounts (Expenses:COGS, Expenses:COGS:AmazonWebServices, Expenses:BusinessExpenses, and Expenses:BusinessExpenses:ChatGPT).

  2. Transactions: It then progresses to record a series of transactions between 2023-03-01 and 2023-05-18.

    • The transaction on 2023-05-14 represents a payment of $17.49 to CONTABO.COM from Mercury Checking ••1234. This is recorded as an expense (Expenses:COGS:Contabo) and a corresponding deduction from the Assets:Bank:Mercury account.

    • Similarly, the transaction on 2023-05-11 represents a payment of $14490.33 to Amazon Web Services from the same bank account. This is logged under Expenses:COGS:AmazonWebServices.

    • The transaction on 2023-03-01 shows income from STRIPE being deposited into Mercury Checking ••1234, totaling $21230.75. This is recorded as income (Income:Stripe) and an addition to the bank account (Assets:Bank:Mercury).

    • The last transaction on 2023-05-18 represents a crypto transaction involving 19 ETH from a customer. This is tracked under Assets:Crypto and Income:Crypto:ETH. The {1,856.20 USD} shows the price of ETH at the time of transaction, while the @@ 35267.8 USD specifies the total value of the 19 ETH transaction.

In all transactions, the principle of double-entry accounting is maintained, ensuring that the equation Assets = Liabilities + Equity always holds true.

Final Thoughts

This Beancount ledger provides a straightforward yet robust system for tracking financial transactions. As seen in the final transaction, Beancount is flexible enough to account for non-traditional assets like cryptocurrency, which is a testament to its utility in our increasingly digital financial landscape.

We hope this breakdown helps you better understand the structure and capabilities of Beancount, whether you're a seasoned accountant or a beginner trying to keep track of your personal finances. Stay tuned for our next blog post, where we'll delve further into advanced Beancount operations.
