What is Journal Entry?
A journal entry is a formal accounting record used to post a financial transaction into the accounting system. It typically identifies the accounts affected, the debit and credit amounts, the date, and a description or reference that explains why the entry was made. Journal entries are the building blocks behind accurate ledgers and financial statements.
For merchants and online businesses, journal entries are used for more than simple sales or expense records. They may record processor fees, payroll accruals, depreciation, inventory adjustments, refunds, chargebacks, intercompany transfers, prepaid expenses, deferred revenue, or corrections to earlier postings. Well-prepared entries make the accounting trail understandable and auditable.
Practitioners care about supporting documentation, correct account mapping, approval controls, and whether manual entries are used to fix real issues or hide poor system configuration. Excessive or unexplained journal entries can signal weak integrations, reconciliation problems, or unreliable month-end close. Good journal entry discipline helps management trust the numbers used for tax preparation, reporting, forecasting, and operational decisions.
Journal Entry Scenario in Month-End Accounting
A merchant closes the month and finds several transactions that cannot be handled by simple bank feed categorization: payment processor fees need to be separated from gross sales, payroll accruals must be recorded, depreciation must be posted, and a refund reserve needs adjustment. The accountant prepares journal entries with debit and credit lines, supporting notes, and review approval so the general ledger reflects the economic activity of the period rather than only bank movements.
How Journal Entries Are Prepared and Reviewed
- Identify the accounting event that requires a journal entry, such as an accrual, depreciation, payroll allocation, inventory adjustment, correction, reclassification, tax entry, or processor fee allocation.
- Determine the affected accounts using the chart of accounts and confirm whether the entry follows double-entry accounting rules.
- Prepare debit and credit lines with amounts, descriptions, period date, supporting documents, and a clear business reason for the entry.
- Separate routine recurring entries from unusual manual entries so higher-risk adjustments receive appropriate review.
- Post the approved entry to the general ledger and confirm that related schedules, reconciliation reports, and financial statements remain consistent.
- Retain support for audit, tax, management review, or future correction, especially when entries affect revenue, expenses, liabilities, taxes, inventory, or owner equity.
Common Journal Entry Mistakes
- Posting entries without enough explanation or supporting documents, making later review and audit support difficult.
- Using journal entries to force accounts to balance instead of investigating the underlying bank, processor, invoice, or system issue.
- Recording revenue, refunds, taxes, or processor fees in the wrong period, which distorts margin and financial reporting.
- Posting manual entries directly to cash accounts without reconciliation evidence.
- Reusing old recurring entries without checking whether the amount, contract, tax treatment, or business situation changed.
- Allowing one person to create, approve, and post high-impact manual entries without review.
Practical Tips for Strong Journal Entry Controls
- Require every journal entry to include a description, preparer, reviewer, posting date, affected accounts, and supporting documentation.
- Use recurring templates for predictable entries such as depreciation, prepaid expenses, payroll accruals, and software allocations, but review amounts each period.
- Flag manual entries affecting revenue, cash, taxes, inventory, reserves, or owner equity for extra review.
- Keep correction entries traceable so the original error, reason for correction, and financial statement impact are clear.
- Reconcile journal entries to supporting schedules, such as fixed asset registers, payroll reports, processor settlement reports, and tax calculations.
- Limit journal entry permissions in the accounting system to trained staff and maintain an audit trail of changes.
Tools Used to Manage Journal Entries
- General ledger systems such as QuickBooks Online, Xero, NetSuite, Sage Intacct, Microsoft Dynamics, or Zoho Books.
- Journal entry templates for accruals, prepayments, depreciation, payroll allocations, processor fees, inventory adjustments, and reclassifications.
- Approval workflows, audit trail reports, close management tools, and supporting document repositories.
- Source reports from payroll systems, payment processors, billing platforms, inventory tools, fixed asset registers, and tax schedules.
- Account reconciliation tools that verify whether journal entries agree with supporting schedules and month-end close workpapers.
Metrics for Reviewing Journal Entry Quality
- Number of manual journal entries posted during each close period.
- Percentage of journal entries with complete supporting documentation and reviewer approval.
- Number of late, backdated, reversing, or correcting entries after the close deadline.
- Value of entries affecting high-risk accounts such as revenue, cash, taxes, inventory, reserves, or equity.
- Recurring entry exception rate, showing how often standard templates required unusual changes.
- Audit or accountant adjustment count caused by incorrect journal entries.
Compliance and Audit Considerations for Journal Entries
Journal entries can materially affect financial statements, tax filings, lender reporting, investor information, and audit evidence. Businesses should maintain approval controls, segregation of duties where practical, supporting documentation, and an audit trail for manual and recurring entries. Accounting treatment may depend on the applicable reporting framework, tax rules, contracts, and jurisdiction, so uncertain revenue, tax, payroll, depreciation, inventory, or reserve entries should be reviewed by a qualified accountant.
FAQ
What is a journal entry in accounting?
A journal entry is a formal accounting record used to post a business transaction into the general ledger. It normally includes the date, affected accounts, debit amounts, credit amounts, description, and supporting reference. In double-entry bookkeeping, total debits must equal total credits. Journal entries are used for routine transactions, adjusting entries, accruals, depreciation, corrections, reclassifications, payroll, tax provisions, and month-end close activities.
Why are journal entries important for bookkeeping accuracy?
Journal entries are important because they translate real business activity into structured accounting records. Without accurate journal entries, revenue, expenses, assets, liabilities, and equity may be reported in the wrong period or under the wrong account. For merchants, entries may be needed to record processor fees, refunds, chargebacks, inventory adjustments, sales tax liabilities, foreign exchange differences, or accruals. Clean journal entry practice supports reliable financial statements, tax preparation, audit trails, and management reporting.
How does a journal entry work in practice?
In practice, the bookkeeper identifies the business event, selects the correct ledger accounts, records equal debit and credit amounts, adds a clear description, attaches evidence, and posts the entry to the accounting system. A simple cash sale may debit cash and credit revenue. A more complex month-end entry may accrue unpaid expenses by debiting an expense account and crediting accrued liabilities. Each entry should be traceable to an invoice, bank record, payroll report, processor statement, contract, or approved calculation.
What is a practical journal entry example for an online merchant?
If an online merchant receives a card settlement of 9,700 after a processor deducted 300 in fees from 10,000 of sales, the journal entry may debit cash for 9,700, debit payment processing fees for 300, and credit revenue or accounts receivable for 10,000, depending on the accounting setup. This makes the bank deposit, revenue, and processing cost visible separately. If refunds, reserves, chargebacks, or VAT/sales tax are involved, the entry may need additional accounts and supporting settlement detail.
What mistakes should businesses avoid when posting journal entries?
Businesses should avoid posting vague entries without descriptions, using suspense accounts for too long, forcing entries to balance without understanding the transaction, and making corrections directly without an audit trail. Other common mistakes include recording revenue or expenses in the wrong period, mixing personal and business items, failing to attach support, and using inconsistent account coding. Journal entries should be reviewed, especially manual entries that affect revenue, cash, tax, payroll, or owner equity.
How can a small business get started with journal entries?
A small business can start by setting up accounting software, defining a chart of accounts, using bank feeds for routine transactions, and creating a simple approval process for manual journal entries. The team should document when manual entries are allowed, what evidence is required, who can post them, and who reviews them at month-end. For most small businesses, routine bookkeeping can be automated, but adjusting entries for accruals, depreciation, corrections, and settlement differences still need accounting judgment.
How should businesses control and improve journal entry quality?
Businesses can improve journal entry quality by using templates, mandatory descriptions, attachment requirements, account restrictions, approval workflows, and periodic review of manual entries. Useful controls include separation between preparer and reviewer, locked accounting periods after close, recurring entry schedules, and exception reports for unusual amounts or sensitive accounts. Good journal entry discipline reduces rework, improves audit readiness, and makes financial statements easier to explain to owners, lenders, tax advisers, and investors.
