Account Reconciliation

Fri, 06 Mar 2026 00:00:00 +0000

Reconciliation is the process of confirming that the balance in your ledger matches the balance reported by an external source — a bank statement, a credit card statement, or a brokerage account. It catches errors, missed transactions, and fraud.

¶Why reconcile

A ledger is only useful if it reflects reality. Reconciliation is the check.
Missed transactions (automatic subscriptions, bank fees, interest) accumulate silently. Reconciliation finds them.
Duplicate entries, wrong amounts, and mis-categorized transactions are caught when the ledger balance does not match the statement balance.

¶Process

Get the statement. Download or retrieve the official balance and transaction list from the institution for the period.

Budgeting

Fri, 06 Mar 2026 00:00:00 +0000

A budget is a plan expressed in numbers. It sets expected income and spending for a future period and provides a standard against which actual results can be compared.

¶Why budget

Without a budget, you discover you overspent only after the money is gone.
A budget forces explicit decisions: if housing takes 40% of income, that leaves 60% for everything else. The allocation is visible.
Comparing budget to actual spending each period reveals patterns — categories that consistently run over, windfalls that mask structural deficits, seasonal variation you can plan for.

¶Structure

A budget mirrors your chart of accounts. For each expense and income account, set a monthly (or period-appropriate) target:

Chart of Accounts

Fri, 06 Mar 2026 00:00:00 +0000

A chart of accounts is the organized list of every account in a ledger. It determines what the books can describe: a well-designed chart makes reporting straightforward; a poorly designed one makes it impossible.

¶Structure

Accounts are grouped by type: assets, liabilities, equity, income, expenses.
Within each type, accounts are organized hierarchically. In plain-text accounting this uses colon-separated names: Assets:Bank:Checking, Expenses:Housing:Rent, Income:Salary.
The hierarchy should reflect how you actually want to see reports. If you need to know how much you spend on groceries versus dining out, those need separate accounts under Expenses:Food.

¶Design principles

Start coarse, refine as needed. Begin with broad categories and split them when you find yourself wanting a distinction the current chart cannot make. Do not pre-build a chart with fifty accounts you may never use.
Match your reporting needs. If you file taxes, your expense categories should align with the categories on your tax forms. If you budget by category, your chart should match your budget categories.
Be consistent. Use the same naming convention throughout. Decide on singular vs. plural, capitalization, and hierarchy depth and stick with it.
Separate accounts by institution. Bank accounts, credit cards, and investment accounts should each be their own account so you can reconcile each one independently.

¶Common domestic accounts

Assets:Bank:Checking, Assets:Bank:Savings — liquid cash
Assets:Receivables — money owed to you
Liabilities:CreditCard:Visa — debts organized by instrument
Equity:Opening-Balances — the offset account for initial balances
Income:Salary, Income:Freelance — revenue sources
Expenses:Housing:Rent, Expenses:Food:Groceries, Expenses:Transport — spending categories

¶In Beancount

Each account must be opened with a directive before it can be used:

Financial Statements

Fri, 06 Mar 2026 00:00:00 +0000

Financial statements are the reports generated from a ledger. They answer three questions: what do you own and owe right now, how much did you earn and spend over a period, and where did the cash actually go.

¶Balance sheet

The balance sheet (or statement of financial position) shows the accounting equation at a point in time:

Assets = Liabilities + Equity

Assets: what you own — cash, investments, property, receivables.
Liabilities: what you owe — credit card balances, loans, mortgages.
Equity: the difference — your net worth.

In domestic accounting, the balance sheet answers: if you paid off all debts right now, what would remain?

Maintain Budget

Fri, 06 Mar 2026 00:00:00 +0000

Set monthly income and expense targets for each account category.
Ensure budgeted expenses plus savings do not exceed budgeted income.
At period close, compare actual income statement lines to budget targets.
Identify categories consistently over or under budget.
Adjust budget or spending based on patterns, not single-period anomalies.
Review budget quarterly and adjust for changed circumstances.

Multi-Currency Accounting

Fri, 06 Mar 2026 00:00:00 +0000

Multi-currency accounting tracks holdings and transactions in more than one currency. This includes foreign currencies, cryptocurrencies, and investment securities — anything denominated in a unit different from your base reporting currency.

¶Core concepts

Operating currency: the currency you report in and think in — usually the currency of the country where you live and pay taxes.
Cost basis: the amount you paid for a holding in your operating currency at the time of acquisition. This is what matters for tax purposes.
Market value: the current value of a holding at today’s exchange rate or price. The difference between cost basis and market value is unrealized gain or loss.
Realized gain/loss: when you sell or convert a holding, the difference between the proceeds and the cost basis becomes a realized gain or loss.

¶In Beancount

Beancount handles multi-currency natively. Each account is opened with a list of allowed currencies:

Period Closing

Fri, 06 Mar 2026 00:00:00 +0000

Closing the books at the end of a period — a month, a quarter, a year — means finalizing the records so that the period’s financial statements are complete and reliable, and the next period starts clean.

¶Why close

Income and expense accounts accumulate over a period. Closing resets them so the next period starts at zero, and the net income flows into equity.
Closing enforces a deadline for recording transactions. After the close, you do not go back and add to the prior period without a clear correction entry.
It produces the final financial statements for the period, which you can use for budgeting, tax preparation, or review.

¶Process

Record all transactions for the period. Ensure nothing is missing — check bank statements, receipts, and any pending items.
Reconcile all accounts. Every bank account, credit card, and cash account should be reconciled against its statement.
Review and correct. Check for mis-categorized transactions, duplicate entries, or unusual amounts.
Generate financial statements. Produce the balance sheet and income statement for the period. Review them for reasonableness.
Close income and expense accounts. In traditional bookkeeping, this means posting journal entries that zero out income and expense accounts and transfer the net to Equity:Retained-Earnings. In Beancount, this is handled automatically by reporting tools — income and expense accounts are reset per-period in reports without explicit closing entries.
Archive. If using plain-text files, commit the ledger to version control with a clear message marking the period close.

¶In Beancount

Beancount does not require explicit closing entries for income and expense accounts. The bean-report tool and Fava handle period boundaries in reports. However, you should:

Read Financial Statements

Fri, 06 Mar 2026 00:00:00 +0000

Generate a balance sheet and confirm assets = liabilities + equity.
Generate an income statement for the period and calculate net income.
Compare income statement to budget to identify over/under-spending.
Check cash flow to confirm sufficient liquidity for upcoming obligations.
Identify trends across periods: growing debt, declining savings, seasonal patterns.

Track Multiple Currencies

Fri, 06 Mar 2026 00:00:00 +0000

Open accounts with the correct currency constraints.
Record conversions using Beancount @ or @@ syntax with accurate cost basis.
Add price directives from consistent sources to track market values.
Reconcile foreign-currency accounts in their native currency.
Review unrealized gains/losses in reports and understand their tax implications.

Beancount Basics

Wed, 31 Dec 2025 00:00:00 +0000

Beancount is a plain-text accounting system with a precise syntax and tooling for validation and reporting.

¶Files and directives

A Beancount file holds transactions, balances, and metadata.
Directives include open, close, balance, pad, and price.
Transactions are dated and list postings that balance.

¶Workflow

Write or import transactions into a .beancount file.
Run the Beancount checker to validate the ledger.
Use reporting tools to inspect balances and activity.

Double-Entry Accounting

Wed, 31 Dec 2025 00:00:00 +0000

Double-entry accounting records every transaction with equal debits and credits. Each entry affects at least two accounts so the books stay balanced.

¶Core ideas

Accounts are grouped as assets, liabilities, equity, income, and expenses.
Every transaction must balance: total debits equal total credits.
The accounting equation holds: assets = liabilities + equity.

¶Example

If you buy equipment for cash, debit the equipment asset account and credit the cash asset account for the same amount.

Plain-Text Accounting

Wed, 31 Dec 2025 00:00:00 +0000

Plain-text accounting keeps ledgers in text files so they are versionable and auditable with standard tools.

¶Why use it

The ledger is human-readable and diff-friendly.
You can automate reports without proprietary formats.
It supports reproducible bookkeeping workflows.

¶Typical structure

A main ledger file with dated transactions.
Account naming conventions such as Assets:Cash or Expenses:Office.
Separate files for prices, budgets, or imports.

Use Beancount Validation

Wed, 31 Dec 2025 00:00:00 +0000

Run the Beancount checker on the ledger file.
Resolve balance errors by fixing missing or mismatched postings.
Track directives that fail validation and fix formatting issues.
Re-run validation until the ledger is clean.
