What it means
Every time money moves in a business, it is recorded through a journal entry. While most transactions happen automatically through billing or payroll software, accountants sometimes need to make manual adjustments.
Journal entry testing is the practice of inspecting these manual changes to ensure they are legitimate and backed by proper documentation. This process matters because manual entries bypass standard automated controls.
This makes them a common route for human error, accidental misstatements, or deliberate manipulation. By reviewing these entries, businesses protect the accuracy of their financial reports and satisfy compliance requirements during annual audits.
In practice, finance teams and external auditors look for red flags. These include entries made late at night, entries posted on weekends, or adjustments processed by staff with unusual access rights.
They also examine round-number amounts and entries that lack descriptions or supporting receipts. Advanced journal entry testing uses data analytics to scan entire ledgers in seconds.
Instead of checking a few random paper slips, auditors can filter thousands of transactions to isolate the highest-risk items for a closer look, saving time while improving accuracy. Journal entry testing is like a bank manager spot-checking handwritten withdrawals instead of trusting the ATM receipt printer.
It ensures that any cash moved by hand actually has a valid reason behind it.
In practice
Real-world examples
Example 1
A startup founder notices a manual entry of $5,000 credited to revenue on a Sunday. Testing reveals it was an accidental duplicate of a customer payment already recorded on Friday. The entry is reversed before the month-end board meeting, and revenue is restated to the correct figure.
Example 2
An SME manufacturing firm reviews manual journal entries and flags three transactions just under its $10,000 approval limit. Further checks show they were split from one $29,400 adjustment to bypass manager sign-off. The finance director reinforces the approval rules and asks for supporting paperwork on every adjustment above a lower threshold.
Example 3
A retail chain uses automated software to test its daily store adjustments. The system flags 50 manual stock write-downs processed by a single branch manager within one month, far more than any other branch. The internal audit team then checks the stock counts and finds that several write-downs were hiding losses from theft.

Case study
Seen in the real world
This is a fictional, illustrative scenario. BrightSpark Logistics, a growing delivery firm with 40 staff, prepared its annual accounts for the bank to secure a growth loan. The finance director noticed a late-season rush of manual adjustments designed to boost net profit by $35,000, helping the company hit its loan covenants. During the preparation for the external audit, the team performed rigorous journal entry testing. They found that several end-of-year accruals lacked invoices, customer contracts, or management approval.
The internal review revealed that an overworked accountant had rushed the entries to meet the bank deadline without proper paperwork. BrightSpark reversed the unverified adjustments, adjusted the accounts to reflect true earnings of $45,000 instead of $80,000, and provided accurate figures to the lender. While the loan took longer to approve, the transparent approach protected the business from regulatory penalties and built long-term trust with the bank. Afterwards, BrightSpark changed its process. Every manual entry above $2,000 now needs a second approver and an attached document, and the finance director runs a monthly report listing entries posted outside working hours.
These simple controls cost a few hours a month and made the next audit noticeably quicker. The bank later commented that the cleaner paper trail made its annual review of BrightSpark's covenants far smoother. The finance director also began training new accountants on why unsupported entries are treated as a red flag, so the habit spread beyond the finance team.
Watch out
Common mistakes
- Testing only large dollar amounts while ignoring a high volume of suspicious small entries that together add up to a material figure.
- Failing to document the rationale behind why specific journal entries were selected for review, which leaves auditors unable to repeat or defend the test.
- Treating journal entry testing as a once-a-year audit chore rather than a regular monthly check that catches problems while they are still easy to fix.
Questions
People also ask
Who is responsible for journal entry testing?
External auditors perform it during financial reviews, but internal accountants and finance managers should also do it monthly, with someone independent of the person who posted the entries.
Are all manual journal entries bad?
No, manual entries are normal for month-end adjustments, tax provisions, and correcting errors. Testing just ensures they are valid, approved and supported by documents.
How many journal entries should be tested?
It depends on company size. Using data analytics, finance teams often screen 100% of entries for risk markers and then examine a smaller sample of the highest-risk items in detail.
