What is Double-Entry Bookkeeping?
Double-entry bookkeeping is the accounting method in which every transaction is recorded in at least two accounts, with equal total debits and credits. The system enforces the accounting equation (Assets = Liabilities + Equity) and is the foundation of modern financial reporting.
How It Works
- Every journal entry has a debit side and a credit side of equal value.
- Debits increase asset and expense accounts; credits decrease them.
- Credits increase liability, equity, and revenue accounts; debits decrease them.
- After posting, total debits in the trial balance must equal total credits.
- Errors are detected when the trial balance does not balance.
Saudi Context
SOCPA-aligned IFRS and ZATCA bookkeeping requirements assume double-entry accounting. Saudi cloud accounting tools such as Qoyod implement double-entry automatically: posting a sales invoice creates Dr Receivable, Cr Revenue, Cr Output VAT once the invoice is approved, and the system rejects any unbalanced entry.
Example
A company buys office furniture for SAR 12,000 in cash. The journal entry is Dr Furniture (Asset) SAR 12,000, Cr Cash (Asset) SAR 12,000. The accounting equation remains balanced because one asset increased while another decreased by the same amount.
