Accounting is one idea repeated ten times

Almost everything in financial accounting descends from a single rule: every transaction affects at least two accounts, and the two sides must agree. Once that clicks, the rest of the subject stops being a list of procedures to memorise and becomes a chain, where each step exists only because the previous one produced something that needs organising.

A transaction is recorded as a journal entry. Entries pile up, so they are sorted by account into a ledger. Ledgers need checking, which is what a trial balance does. A verified trial balance is then rearranged into the three statements: the balance sheet for what you own and owe, the profit and loss for what you earned, and the cash flow statement for what actually moved. Everything else on this page is either a refinement of that chain or a check on it.

The order matters more than the volume. People who struggle with accounting have usually met depreciation or inventory valuation before they were comfortable with debits and credits, and concluded the subject is arbitrary. It is not. Follow the map below top to bottom and each concept arrives only when you already have what it needs.

The Concept Map

The ten concepts, and what each one is for

These are the ten accounting topics in the study tool, arranged in the order they build on each other rather than alphabetically.

Accounting Basics

The vocabulary and the rules of the game: what an account is, why every entry has two sides, and the difference between recording a transaction and interpreting it.

Journal Entries

The original record. Every transaction enters the books here first, with a debit, a credit and a date, before it is sorted anywhere else.

Ledger and Accounts

The same entries regrouped by account rather than by date, so you can see the running balance of cash, sales or a specific customer.

Trial Balance

The arithmetic check. Total debits must equal total credits. It catches slips of the pen, but not an entry posted correctly to the wrong account.

Balance Sheet

A position at one instant: assets on one side, liabilities and equity on the other. It answers what the business owns and who has a claim on it.

Profit and Loss Statement

A period rather than an instant. Revenue earned less expenses incurred, which is not the same as money received less money paid.

Cash Flow Statement

The reconciliation between the two above. It explains why a profitable business can have an empty bank account, split across operating, investing and financing activity.

Bank Reconciliation

Matching your cash book to the bank statement. The gaps are usually timing, occasionally charges you did not know about, and sometimes an error worth finding.

Depreciation and Amortisation

Spreading the cost of a long-lived asset across the years that use it, so one year does not carry a cost that five years benefit from.

Inventory Valuation

Deciding what your unsold stock is worth. The method you choose changes both the balance sheet and the reported profit, which is why the rules constrain it.

Test yourself on Accounting

Ten topics with multiple-choice questions, flashcards, word scrambles and crosswords. Accounting is a subject where recall matters, and reading it once is not the same as knowing it.

Common Questions

Before you start

Do I need accounting if I only want to invest?+
You need the three statements and roughly the first six concepts on this page. Fundamental analysis is largely the act of reading a balance sheet, a profit and loss account and a cash flow statement with suspicion, and you cannot be suspicious about a document you cannot read. You can safely skip the bookkeeping mechanics, journal entries and reconciliation, which matter to whoever prepares the accounts rather than to whoever reads them.
What is the difference between bookkeeping and accounting?+
Bookkeeping is the recording: journal entries, ledgers, reconciliation, keeping the raw data accurate and complete. Accounting is everything built on top of that data, which includes preparing the statements, choosing between permitted treatments such as an inventory method, and interpreting what the result means. Bookkeeping has right answers. Accounting frequently has defensible choices.
Why does the trial balance agree when there is still an error?+
Because it only tests that debits equal credits, not that either was posted to the correct account. An entry recorded in the wrong account, an entry omitted entirely, or an entry duplicated on both sides all leave the trial balance perfectly balanced. That is why reconciliation and review exist as separate steps rather than being folded into the same check.
