Quickbooks Rules are the built-in automation in QuickBooks Online that categorize downloaded bank and credit card transactions by looking for a specific phrase in the text the bank includes with each transaction.
Rules run on the Banking Transaction Download screen, where 📝Quickbooks Online collects transactional data each day from connected bank and credit card accounts. A rule that matches a phrase can assign the account, payee and class automatically, which reduces the manual work described in 📝Accepting Transactions in Quickbooks Online. Because rules match text rather than meaning, they misfire when banks vary their descriptions, and anything no rule catches still needs review.
📝Effortless Downloaded Transaction Entry describes how 📝Weekly Accounting builds on rules, and 📝Set up the rules yourself covers the do-it-yourself path. As of 2026, Intuit also offers automatic categorization suggestions alongside rules, and the screen now sits under Transactions > Bank transactions; the screenshot below shows the older layout.
Rules enable primitive automation. They have gotten better and will keep getting better, but presently they're a blunt instrument.
