QuickBooks Online glossary terms for bookkeepers: Undeposited Funds, Uncategorized Expense, bank rules, class/location tracking, and cleanup traps.

Some bookkeeping terms exist because QuickBooks Online exists. They are not textbook vocabulary, but they show up in real client cleanup work every week. If a bookkeeper does not understand them, the file can look fine on the surface while cash, revenue, and clearing accounts drift.
Start with Undeposited Funds. It is a holding account for payments received before they are batched into a bank deposit. A clean book has near-zero Undeposited Funds at month-end. Then check Uncategorized Expense, the account QBO uses when it does not know where a transaction belongs. That balance should also be near zero after review.

Uncategorized Expense is QuickBooks Online's catchall for transactions imported but never assigned to a real category. A clean book has $0 in this account. Here's how to recategorize what's there and prevent new ones from landing.
