Every purchase, sale, or exchange is a transaction. Money changes hands, goods or services are delivered, and records are created. From a cup of coffee to a corporate merger, the same basic idea applies.

Transactions can be simple or complex. A retail purchase settles instantly. A securities trade may involve clearing and settlement over several days. In accounting, each transaction is recorded to track income, expenses, assets, and liabilities.

Accuracy matters. Clear documentation supports financial reporting, auditing, and dispute resolution. Digital systems have accelerated processing, but the underlying principle remains a verifiable exchange between parties.

Key elements

• Two or more parties involved
