Accounting Concepts & Standards
What Is a Ledger in Accounting?
A ledger in accounting is the organized record that sorts every business transaction into individual accounts, so each account (cash, accounts payable, sales revenue) shows its running balance in one place. Where a journal lists transactions in date order, the ledger regroups those same entries by account. The ledger is the source that feeds the trial balance and the financial statements.
Accountants sometimes call the ledger “the book of final entry” because a transaction lands there after it is first recorded in a journal. Under a double-entry system, every posting keeps the accounting equation (Assets = Liabilities + Equity) in balance, because each entry carries equal debits and credits.
What a ledger does in the accounting cycle
A ledger collects and summarizes transactions by account after they are journalized, then produces the balances used to build the trial balance and financial statements. It sits in the middle of the accounting cycle: source document, journal entry, ledger posting, trial balance, adjusting entries, statements.
The ledger answers a different question than the journal. The journal answers “what happened, and when?” The ledger answers “what is the balance of this specific account right now?” Because the ledger groups by account, a bookkeeper can read the cash account’s full history in one column instead of hunting through every dated entry. This structure is what makes month-end close and audit trails workable.
Every ledger account traces back to the chart of accounts, the numbered list that defines which accounts a company uses and how they are grouped.
The general ledger vs subsidiary ledgers
The general ledger holds a summary account for every line reported on the financial statements, while subsidiary ledgers hold the transaction-level detail behind a single control account. The two tie together: a subsidiary ledger’s total must equal its general ledger control account.
The general ledger (often abbreviated GL) is the master record. Most small businesses use only a general ledger. Larger companies add subsidiary ledgers when one account has too many moving parts to track in a single line. The most common examples are the accounts receivable subsidiary ledger (one page per customer) and the accounts payable subsidiary ledger (one page per vendor).
| Ledger type | What it holds | Example | Ties to |
|---|---|---|---|
| General ledger | Summary balance for each account on the financials | Accounts Receivable control account: $84,000 | The trial balance |
| Accounts receivable subsidiary ledger | Balance owed by each individual customer | Customer A $30,000; Customer B $54,000 | The AR control account |
| Accounts payable subsidiary ledger | Balance owed to each individual vendor | Vendor X $12,000; Vendor Y $9,000 | The AP control account |
| Inventory subsidiary ledger | Quantity and cost per item (SKU) | 400 units at $15 each | The Inventory control account |
If a subsidiary ledger total does not match its control account, there is a posting error to find before closing the period. For the full mechanics of the master record, see what a general ledger is and how it works.
The five types of ledger accounts
Every ledger account falls into one of five categories: assets, liabilities, equity, revenue, or expenses. The first three are permanent (balance sheet) accounts that carry their balances forward each year. The last two are temporary (income statement) accounts that reset to zero at year-end through closing entries.
The category also sets the account’s “normal balance,” meaning the side (debit or credit) that increases it. Assets and expenses increase with debits. Liabilities, equity, and revenue increase with credits. These rules never change, and they are why a correctly posted ledger always balances.
| Account type | Statement | Normal balance | Increased by | Examples |
|---|---|---|---|---|
| Assets | Balance sheet | Debit | Debit | Cash, accounts receivable, inventory, equipment |
| Liabilities | Balance sheet | Credit | Credit | Accounts payable, loans, accrued expenses |
| Equity | Balance sheet | Credit | Credit | Common stock, retained earnings |
| Revenue | Income statement | Credit | Credit | Sales revenue, service revenue, interest income |
| Expenses | Income statement | Debit | Debit | Rent, wages, cost of goods sold, utilities |
For the underlying rule set, see debits and credits explained and the mechanics of double-entry accounting.
How posting from journal to ledger works
Posting is the step that copies each journal entry into the matching ledger accounts, keeping the same date, debit, and credit amounts without changing anything. The journal is where a transaction is first written; the ledger is where those figures are sorted by account so a running balance can be calculated.
Follow these steps to post an entry:
- Locate the journal entry, including its date, accounts, and debit and credit amounts.
- Open the ledger account named on the debit line and enter the debit amount, using the original transaction date.
- Open the ledger account named on the credit line and enter the credit amount, using the same date.
- Update each account’s running balance: for asset and expense accounts, debits minus credits; for liability, equity, and revenue accounts, credits minus debits.
- Repeat for every line, then confirm total debits across all accounts equal total credits.
Consider a $2,000 cash sale. The journal entry debits Cash $2,000 and credits Sales Revenue $2,000. Posting moves the $2,000 debit into the Cash ledger account and the $2,000 credit into the Sales Revenue ledger account. In a modern accounting system this posting happens automatically the moment the entry is saved, but the logic is identical to the manual process.
Once every entry is posted, the ending balance of each ledger account is listed on the trial balance, where total debits should equal total credits before statements are drafted.
Ledger vs journal: the core difference
A journal records transactions chronologically as they occur; a ledger regroups those same transactions by account to show balances. The journal is the “book of original entry” and the ledger is the “book of final entry.” Data flows one direction: journal first, ledger second.
| Feature | Journal | Ledger |
|---|---|---|
| Order of records | By date, as transactions happen | By account |
| Also called | Book of original entry | Book of final entry |
| Primary purpose | Capture each transaction with detail | Show the balance of each account |
| Level of detail | Full narrative (date, accounts, description) | Summarized by account |
| Comes from | Source documents | The journal (via posting) |
| Feeds | The ledger | The trial balance and statements |
Both are required in a double-entry system. Skipping the journal removes the chronological audit trail; skipping the ledger means no account balances and no way to build the financial statements.
Frequently asked questions
What is the difference between a ledger and a general ledger?
“Ledger” is the general term for any book of accounts. The “general ledger” is the specific master ledger that holds a summary account for every line on the financial statements. A business may also keep subsidiary ledgers (for receivables, payables, or inventory) that feed detail into general ledger control accounts. In everyday use, many people say “ledger” when they mean the general ledger.
Is a ledger the same as a balance sheet?
No. A ledger is the working record of every account and its running balance. The balance sheet is a formal statement, built from ledger balances, that reports assets, liabilities, and equity at a single point in time. The ledger holds all five account types; the balance sheet reports only the three permanent ones. Revenue and expense balances flow instead to the income statement.
What are the main types of ledgers?
The three common types are the general ledger (the master summary of all accounts), subsidiary ledgers (detail behind one control account, such as accounts receivable by customer), and, in some manual systems, special-purpose ledgers. Most small businesses operate with only a general ledger. Companies add subsidiary ledgers when a single account, like receivables, has too many individual balances to track in one line.
Do you post to the ledger before or after the journal?
After. A transaction is recorded first in a journal (the book of original entry), then posted to the ledger (the book of final entry). Posting copies the same date and the same debit and credit amounts into the individual ledger accounts. In computerized systems the posting is automatic and instant, but the sequence, journal first, then ledger, still holds.
Why does a ledger use debits and credits?
Ledgers use debits and credits because accounting is a double-entry system: every transaction affects at least two accounts, with total debits equal to total credits. This keeps the accounting equation (Assets = Liabilities + Equity) in balance and lets each account calculate a running balance on its normal side. It also creates a built-in error check, since an out-of-balance ledger signals a posting mistake.
How many ledgers does a business need?
Most small businesses need only one, the general ledger, which contains every account. A business adds subsidiary ledgers when a single account carries many individual balances that need separate tracking, such as amounts owed by dozens of customers or to many vendors. The right number depends on the volume and complexity of transactions, not on a fixed rule.
