Accounting is the practice of keeping a clear, honest record of a business’s money. It covers everything of value the business owns or owes, not just the cash on hand. Think of it as a diary that answers three questions at any moment: what came in, what went out, and where do we stand right now. A business wants to know what it owns, what it owes, and whether the two add up. Accounting is how it keeps that picture accurate, day after day.

​
The three things every business tracks

Accounting watches three flows:
  • Money coming in: sales, payments from customers, loans received, money the owners put in.
  • Money going out: rent, salaries, supplies, loan repayments.
  • What’s owned vs. what’s owed: the cash, equipment, and money others owe you, balanced against the debts you still have to pay.
A good record keeps these connected. If money moved, write it down. If something is owned or owed, account for it. Controls and reconciliation help identify missing or inconsistent records.

Why it has to be trustworthy

Imagine running a shop where you think you have money but aren’t sure. You can’t pay suppliers with a guess, prove to a bank that you’re worth lending to, or tell if you’re making a profit. Accounting uses records and controls to make financial information checkable. A balanced entry is an arithmetic check: it confirms the recorded sides match, but does not by itself prove authorization, classification, or completeness.
