Journal Entry

Journal Entry Definition

A journal entry is a record of a financial transaction in the accounting system, showing the accounts debited and credited along with the amounts. Every journal entry must balance—total debits must equal total credits. Journal entries are the building blocks of double-entry bookkeeping and how transactions get recorded in the general ledger.

Journal Entry in Practice — Example

A small marketing agency pays $2,400 upfront for a 12-month software subscription. The bookkeeper records a journal entry: debit Prepaid Expenses $2,400 (an asset—value not yet consumed) and credit Cash $2,400 (money left the account). Each month, a second journal entry moves $200 from Prepaid Expenses to Software Expense, recognizing one month's worth of the subscription. This spreads the cost over the period it benefits.

Why Journal Entry Matters for Your Books

Journal entries are how you make your books accurate beyond what automated bank feeds capture. While QBO handles routine transactions like invoices and bills automatically, adjusting entries for depreciation, prepaid expenses, accrued liabilities, and error corrections all require manual journal entries.

Without these adjustments, your financial statements are incomplete. Depreciation won't appear, prepaid expenses won't be amortized, and revenue won't be properly matched to the periods it belongs in. Month-end close procedures rely heavily on journal entries to get the books right.

Journal entries also create a clear audit trail. Each entry includes a date, reference number, affected accounts, amounts, and a memo explaining why the entry was made. This documentation is invaluable during audits, tax prep, and troubleshooting.

How Journal Entry Shows Up in QuickBooks

In QBO, create journal entries via + New → Journal Entry. Select the date, add line items with the accounts to debit and credit, enter the amounts, and include a memo. QBO enforces that debits equal credits before saving. View all journal entries under Reports → Journal or search by date range. Set up recurring journal entries (gear icon → Recurring Transactions) for repetitive month-end adjustments like depreciation. Journal entries post automatically to the general ledger and appear on financial statements.

Common Mistakes

Creating journal entries without memos: Six months later, a journal entry with no description is a mystery. Always document the purpose—"December depreciation" or "Correct misclassified rent payment."

Using journal entries for routine transactions: Don't use journal entries to record sales, purchases, or payments. Use QBO's native transaction types (invoices, bills, expenses) for those. Journal entries are for adjustments and non-routine items.

Making entries that don't balance: Debits must always equal credits. An unbalanced entry throws off the trial balance and every report downstream.

FAQ

Q: How often should journal entries be made?

A: Regular adjusting entries happen at month-end (depreciation, accruals, prepaids). Correcting entries happen as needed whenever errors are discovered. Avoid making journal entries so frequently that they replace proper transaction workflows.

Q: Can I delete a journal entry in QuickBooks?

A: Yes, but it's better to create a reversing entry. Deleting removes the audit trail. A reversing entry shows what happened and preserves the record.
