记账 literally means 'to record accounts' — the character 记 (jì) means 'to record, to note down', and 账 (zhàng) means 'account, account book, or financial record'. Together, they form a verb meaning 'to keep accounts' or 'to track income and expenses', commonly used in personal finance, small business management, or household budgeting. It implies systematic recording of monetary transactions, often with dates, categories, and amounts.

This word is frequently used in daily life — for example, when using mobile apps like Alipay or WeChat Pay that offer built-in记账 features, or when someone manually logs purchases in a notebook or spreadsheet. It carries a neutral, practical tone and is appropriate in both informal conversations and formal financial contexts. While it can refer to professional accounting, it more often describes basic, self-managed financial tracking rather than complex bookkeeping performed by certified accountants.
