1.2Journal, general ledger, trial balance
The essentials in 30 seconds
- Journal: transactions recorded chronologically, each entry balanced — the mandatory entry point.
- Ledger: the same entries re-sorted by account, with each one's movements and balance.
- Trial balance: the summary of all accounts (debits, credits, balances) — a major control (debits = credits) leading to the balance sheet and income statement.
Running case — Rachid and the customer balance that looks wrong
Rachid's accountant flags an odd “receivables” balance at the trading SME. Instead of re-reading everything, he opens the account's ledger: all that customer's movements are grouped there, and the faulty entry jumps out — an invoice entered twice in the journal. Then the trial balance confirms everything balances again. Rachid gets the chain: journal for trace, ledger for detail, trial balance for control.
Sequel to case 1.1 — Rachid follows his transactions through the accounting chain.
1. The journal
Everything starts with the journal: transactions are recorded chronologically, each entry respecting double-entry bookkeeping (date, accounts, description).
It is the raw, dated trace of all accounting activity — the mandatory entry point.
2. The general ledger
The same entries are reorganised by account in the general ledger: you see all the movements of each account ("customers", "bank"…) and its balance.
3. The trial balance
The trial balance summarises all the accounts with, for each, total debits, total credits and balance. It is a major control (total debits = total credits), and from it the balance sheet and income statement are prepared.
The same information from three angles: chronological, by account, summary.

What the chain is for.
The "customers" account balance looks wrong?
→ check the general ledger of the account to find the faulty entry.
The trial balance verifies that everything is balanced before the balance sheet.Result: understanding how transactions become summaries.
Reflex: each angle answers a different question.
Section vocabulary
- Journal
- Register recording transactions chronologically, each entry balanced (debits = credits).
Simple example: Rachid's customer invoice is entered there at its issue date.
What it is not: a summary by account — that is the ledger's job.
Reflex: every document first recorded in the journal, with its date.
- General ledger
- Entries re-sorted by account: all movements and the balance of each account.
Simple example: Rachid's “receivables” ledger reveals the twice-entered invoice.
What it is not: the overall-control document — that is the trial balance.
Reflex: doubtful balance? open the account's ledger.
- Trial balance
- Table summarising all accounts with each one's total debits, credits and balance; a control tool.
Simple example: Rachid's trial balance confirms debits = credits before the balance sheet.
What it is not: the balance sheet itself — the trial balance prepares it, not replaces it.
Reflex: check the trial balance's equilibrium before any summary.
- Account balance
- Difference between an account's total debits and credits (debit or credit balance).
Simple example: The odd “receivables” balance alerting Rachid's accountant.
What it is not: the gross total of movements with no offsetting.
Reflex: read the balance, not just the movements.
- Accounting chain
- The journal → ledger → trial balance → summary documents (balance sheet, income statement) sequence.
Simple example: Rachid's sales flow up to the balance sheet through this chain.
What it is not: three independent documents with no link.
Reflex: follow the chain in order for any diagnosis.
In practice — In practice — Understanding the accounting chain
- Locate the journal: chronological recording of each transaction (double entry), mandatory entry point.
- Locate the general ledger: reorganisation of entries by account, with the balance of each.
- Locate the trial balance: summary of all accounts (total debits, total credits, balance) — a control tool.
- Check the link: same entries, three angles (chronological, by account, summary) leading to the annual accounts.
Ready-to-say script — asking the accountant for the right document (20 s)
“To check this customer balance, can you pull the account's ledger? And the latest trial balance, to see if the whole is balanced before we dig further?”
Say it to your accountant when a figure surprises you: ask for detail (ledger) then control (trial balance).

OVERALL TRIAL BALANCE IN EQUILIBRIUM (debits = credits)? YES / NOSmall business / tight budget
No software needed: a dated journal book + one card per account (manual ledger) + a month-end trial-balance table is enough.
Algiers trading SME
Many customer/supplier movements: check the ledger of big accounts every month, not only at year-end.
With accounting software
Software generates ledger and trial balance alone: Rachid's work becomes reading and diagnosis, not manual production.
With an external accountant
Rachid sends dated documents filed for the journal; the accountant keeps ledger and trial balance — demand the trial balance each quarter.
✓ Best practices
- To diagnose a wrong balance, check the general ledger of the account concerned.
- Use the trial balance as an overall control (debits = credits).
- Understand the chain even if the software automates it.
✗ Common pitfalls
- Believing that journal/general ledger/trial balance are three different pieces of information (it's one, seen from three angles).
- Entering data without understanding the chain (errors that cannot be diagnosed).
- Not checking that the trial balance balances before the balance sheet.
Key takeaways
- Journal: chronological recording of transactions (each entry balanced).
- General ledger: the same entries reorganised by account, with the balances.
- Trial balance: summary of all accounts (total debit/credit/balance), a control tool (debits = credits).
- The journal → general ledger → trial balance chain leads to the balance sheet and income statement.

Open the ledger of one account (receivables or bank) and read its last 5 movements: trace each back to its original journal entry. Note in one sentence what each document taught you.
- I can place journal, ledger and trial balance in one sentence each.
- I know which document to consult per question (date, account, control).
- I have read 1 real ledger and traced its entries.
Frequently asked questions
Journal, general ledger, trial balance: is it the same information three times?
Yes and no: it is the same information, but from three complementary angles. The journal presents transactions in chronological order (ideal for "what happened on 15 March?" and traceability). The general ledger reorganises them by account (ideal for "what is the detail and balance of Mr Smith's customer account?"). The trial balance gives a summary view of all accounts (ideal for the overall control and for preparing the summary documents). None is redundant: each answers a question. And the trial balance lets you check that everything is balanced (debits = credits) before preparing the balance sheet and income statement.
Today, with software, do you still need to understand this chain?
Yes. Software automatically generates the general ledger and trial balance from the entries recorded in the journal. But understanding the chain remains essential: to check and correct (when a balance looks wrong, check the general ledger of the account to find the faulty entry); to read and use these documents (banker, manager, controller all analyse them); and to avoid being "a pilot who doesn't understand the instruments". Software automates the execution, not the understanding, which remains the heart of the job — like a calculator computes but you still need to know which operation to enter.
