1. Open the Chart of Accounts. Go to the gear icon, then Chart of Accounts. In QuickBooks Desktop, it's Lists > Chart of Accounts, or the shortcut Ctrl+A.
2. Click New. In Desktop, the shortcut is Ctrl+N from inside the Chart of Accounts window.
3. Choose the Account Type first. Asset, Liability, Equity, Income, or Expense. This single choice decides which financial statement the account shows up on, so pick it before anything else.
4. Choose a Detail Type. A more specific classification under the main type, like Checking versus Savings under Bank, or Travel versus Office Supplies under Expense. This is what controls how the account behaves on reports, not the generic Account Type alone.
5. Name it the way your team actually talks about it. Add a description or an account number if your chart uses numbered accounts; neither is required to save.
6. Make it a sub-account if it should roll up under an existing one. Check Is sub-account, then pick the parent account, if this is a subdivision of something that already exists rather than a standalone line.
7. Save. The account is available immediately everywhere QuickBooks asks you to categorize something: invoices, bills, expenses, journal entries, and bank feed rules.
