| Transaction Type | Why QuickBooks Does Not Remove It |
|---|---|
| Payroll Transactions | Preserves employee history, tax filings, payroll liabilities, and compliance-related records |
| Invoices, Payments, Credit Memos, and Refund Checks | Transactions are not properly linked |
| Payments Recorded to Undeposited Funds | Payments have not been included in a deposit |
| Bills, Bill Credits, and Bill Payment Checks | Related transactions are not correctly connected |
| Estimates Linked to Invoices | Estimates are non-posting transactions |
| Transactions Linked to Non-Condensable Entries | Required to preserve transaction integrity |
| Sales Tax Transactions | Sales tax was paid using a regular check instead of the Pay Sales Tax feature |
