Every bank or card transaction that arrives through a bank feed needs an account: rent, software subscriptions, cost of goods sold, owner's draw, a transfer or a loan payment. QuickBooks Online and Xero both suggest categories and let users create bank rules, and add-on tools such as Dext and Booke AI add more automation. These systems combine two methods. Rules are explicit, for example: 'if the description contains ADOBE, code to Software.' They are predictable but break when descriptions change. Machine-learning models are statistical. They learn from how this company, and often many other companies, coded similar transactions. They use features such as the cleaned-up payee name, the amount, the day of the month, whether money came in or went out, and sometimes the merchant category code attached to card transactions. The model outputs a suggested account with a confidence score. When a bookkeeper accepts or corrects a suggestion, that decision becomes training data, so the system adapts to each client over time. Errors cluster in predictable places. Vendors that sell many kinds of goods, such as Amazon, Costco or a hardware store, could mean supplies, inventory, equipment or personal spending. Transfers between the business's own accounts, loan proceeds and owner contributions can look like income. Loan payments mix principal and interest. Refunds and chargebacks may be coded as new revenue. Personal expenses on a business card belong under owner's draws or reimbursements, not deductible expenses. A new vendor with no history gets a guess based on how other companies coded it, which may not fit this business. A common misconception is that auto-categorized means correct. Categorization only proposes a classification. It does not prove that a transaction appears only once, belongs to the right period or matches a receipt. Good practice is to review low-confidence items, large amounts, first-time vendors and anything touching balance sheet accounts. Then compare category totals with prior months to spot anything unusual.
