Full entry →, the working definition in this lesson coming from OpenStax's Principles of Accounting. Each asset, liability, equity, revenue, and expense has its own account. Posting The step of the accounting cycle that moves journal entries into the general ledger, copying each entry into the account it affects. Full entry → copies Journal The chronological record of a business's transactions, written down in the order they happen before they are posted to the ledger.

The Chart of accounts The organized, numbered list of every account a business uses, arranged in the order the accounts appear on the financial statements. Full entry → lists every account a business uses. The ledger matters because it turns a diary of events into usable totals — it is the memory of the business.
Why this matters
A journal tells you what happened and when, but a business runs on totals: how much cash is left, what customers owe, what a month's sales added up to. The ledger is what makes those totals possible, because it collects every transaction into the account it touches. Lenders, owners, and managers all read numbers that trace back to the ledger, and auditors follow the same trail in reverse — every figure on the statements can be traced to a ledger account, and every ledger entry to a journal entry. Practically, that means a business can answer a simple question — how much do we have? — by reading one account instead of re-reading the whole diary. And the chart of accounts keeps the whole collection organized.
The college version
What the general ledger is
OpenStax's Principles of Accounting puts the ledger at the foundation: the basic components of even the simplest accounting system are accounts and a general ledger. CFI describes the same object from the other side — the general ledger is a record of all past transactions of a company, organized by accounts. Put together, the working definition in this lesson: the general ledger is the complete set of a company's accounts, where every transaction ends up collected by account. Notice what the definition does. It is not a list of events in time order; that is the journal, which has its own lesson. It is a filing system by account, so that everything touching cash lands in the Cash account, everything touching sales lands in the Sales account, and so on. The ledger can be a paper book or a file inside accounting software — the form changes, the job does not.
The accounts inside the ledger
Every asset, liability, equity, revenue, and expense a business uses gets its own account in the ledger — five families, stated simply. OpenStax says each category in the accounting equation includes many individual accounts, all of which a company maintains in its general ledger. CFI makes the same point with examples: cash is part of a company's assets, and on the ledger each asset has its own account — cash in one account, accounts receivable in another. A taco truck, for instance, carries a Cash account, a Supplies account, a Loan Payable account, a Sales account, and a Rent Expense account, each holding only its own activity. Each family has its own lesson — assets, liabilities, equity, revenue, and expenses — so here the point is just the structure: five families, one account per item, all living in the ledger.
Posting: how entries get there
Posting is the step that copies journal entries into the ledger. OpenStax defines it in one line: posting takes all transactions from the journal during a period and moves the information to a general ledger. The journal is where transactions are first written down, in order; posting is the bridge that carries each entry into the accounts it affects. How journal entries are structured belongs to the journal-entries lesson — here the step is just named and placed. In accounting software the bridge is automatic: an entry saved to the journal is posted to the ledger at the same moment. By hand, posting means writing each entry's amount onto the right account page. Either way, the ledger ends up with all the accounts used during the period, not just the accounts touched by one transaction.
The ledger's shape: running balances by account
The journal reads like a diary: first this happened, then that happened. The ledger reads like a set of files: one page per account, each page gathering only its own entries. OpenStax pictures each account as a T-account — a two-sided table — where the balance is the running result of everything recorded in it. CFI describes the same shape in words: a general ledger sorts all transaction information through the accounts, and each account holds the transactions that affect it, with the date, description, and amount of each. So the shape is simple to describe: chronological entries from the journal, sorted by account, accumulating into a Running balance The amount an account shows at any moment, after all of its recorded entries have been added and subtracted. Full entry → on every account page. Ask what happened on Tuesday and you read the journal. Ask how much cash you have and you read the Cash account's balance.
Why the ledger matters
The ledger's core value is that it turns a diary of events into usable totals. A stack of journal entries tells you what happened, but not what anything amounts to; the ledger groups each item so its total is always at hand. That is why CFI calls the ledger the primary source for generating the trial balance and financial statements — it is the data source used to construct the balance sheet and the income statement. The trial balance, which has its own lesson, takes account balances from the ledger and checks them. So the chain runs: journal entries are posted to the ledger, the ledger's account balances feed the trial balance, and the statements are built from there. Nothing in that chain works without the ledger's by-account totals.
The chart of accounts — and the honest framing
The chart of accounts is the organized list of every account a business uses. OpenStax: when a company starts analyzing, it makes a list of all the accounts used in day-to-day transactions, numbered by category — assets start with 1, liabilities with 2, equity with 3, revenues with 4, expenses with 5 — and the accounts appear in the order they show up on the financial statements. CFI adds that the chart provides a complete list of all the accounts in the general ledger, each with a name and an identification code. One line: the chart of accounts is the menu; the ledger is the collection of accounts with their activity inside. And the honest framing: the ledger is the memory of the business. Every number on the financial statements traces back to a ledger account, and every ledger entry traces back to a journal entry — which is exactly the trail auditors follow when they check a company's books.
Eli explains
The same idea, in plain words
Explain it like I’m 10
A business does two kinds of writing. First it writes down what happened, in order: Monday sold tacos for $80, Tuesday bought supplies for $30. That list is the journal — a diary. Then it copies each line into the right folder: the $80 goes in the Cash folder, the $30 also goes in the Cash folder, and the supplies purchase goes in the Supplies folder. Those folders together are the general ledger. The diary answers "what happened on Tuesday?" The folders answer the question businesses actually ask: "what does our cash look like right now?" Every folder keeps a running total, so you can glance at one folder and know the answer.
Picture it like this
Think of a week of receipts dropped into a shoebox in the order they arrived — that is the journal. Now sort every receipt into labeled jars: a Cash jar, a Supplies jar, a Sales jar. At the end of the week, each jar holds only its own receipts, and you can weigh one jar without re-reading the whole box. The jars are the ledger.
Where the picture stops working
The jars only sort single pieces of paper, but a real ledger entry carries two sides at once — every transaction touches at least two accounts — so one event shows up in two jars. And jars get sorted once a week, while accounting software updates the ledger the moment an entry is saved. The analogy captures the organizing, not the mechanics.
Worked example
Bluebird Tacos is a food truck run by Elena. In one week her journal gets four entries: Monday, a cash sale of $80; Tuesday, supplies bought for $30 cash; Wednesday, a customer pays the $50 she owed from last week; Thursday, a $25 payment on the truck's equipment loan. Posting carries each entry into the ledger. The Cash account receives four lines: 80 in, 30 out, 50 in, 25 out — running balance 80, then 50, then 100, then 75. The Sales account shows 80, the Supplies account shows 30, Accounts Receivable drops by the 50 collected, and the loan account shows the 25 paid. When Elena wants to know how much cash she has, she reads the Cash account and sees $75 — no need to re-read the week. Those account totals are exactly what later feed the trial balance and the financial statements.
Key takeaway
The general ledger is the business's memory: every transaction ends up in an account there, every account carries a running balance, and every number on the financial statements traces back to it.

Common mistakes
Treating the journal and the general ledger as the same thing.
They hold the same transactions arranged differently: the journal is chronological, in the order events happened; the ledger is by account, with each account gathering only its own entries.
Expecting the ledger to read like a story of the business.
The ledger tells per-account stories, not day-by-day ones. The Cash account shows the whole cash story; to see what happened on a specific day, you read the journal.
Confusing the chart of accounts with the ledger itself.
The chart of accounts is the organized list of account names a business uses — a menu. The ledger is the actual collection of accounts with all their recorded activity — the filled-in records.
Assuming the ledger catches mistakes on its own.
The ledger organizes transactions into accounts; it does not check itself. Checking is the trial balance's job — it takes the ledger's balances and confirms that total debits equal total credits.
Easily confused
Journal vs. General ledger
The journal is the chronological diary of transactions, in the order they happen; the ledger is the same information sorted by account. Posting is the step that moves entries from one to the other.
Chart of accounts vs. General ledger
The chart of accounts is the organized list of account names a business uses, like a menu; the general ledger is the accounts themselves with their activity and balances, like the filled-in records.
General ledger vs. Trial balance
The ledger is the permanent home of the accounts and their running balances; the trial balance is a snapshot report drawn from those balances, used to check that debits equal credits.
