| Reversal of Accounts |
Debited the account that should have been credited (e.g., debited Cash when paying rent). |
Put the expense/asset on the Debit side; put departing Cash on the Credit side. |
| Wrong Account Category |
Used an expense instead of an asset (or vice versa), e.g., calling Equipment "Supplies Expense". |
Capitalize the proper long-term asset account instead of expensing it. |
| Transposition / Slide |
Swapping digits (e.g., $540 vs. $450) or omitting a zero ($1,000 vs. $100). |
Ensure total debits exactly equal the true agreed invoice dollar amount. |
| Cash Timing Misunderstanding |
Credited Cash when buying on account (credit), or credited Revenue before work is performed. |
Use Accounts Payable, Accounts Receivable, or Unearned Revenue. |
