# What Happens When a Business Cannot Explain a Number in Its Financial Statements?

What Happens When a Business Cannot Explain a Number in Its Financial Statements?

Every number in a company’s financial statements is supposed to have a story behind it. Revenue should be supported by sales records. Cash should agree with bank balances. Accounts receivable should be linked to outstanding customer invoices. Expenses should come from supplier bills, payroll records, contracts, receipts, or other documentation.

But what happens when someone asks a simple question about a figure in the financial statements and nobody can explain where it came from?

A balance may have been carried forward for years. An accountant may have inherited it from a previous bookkeeper. A journal entry may have been posted without sufficient documentation. A reconciliation may no longer support the figure shown in the general ledger.

At first, an unexplained number may seem like a small bookkeeping inconvenience. In reality, it can be a warning sign of a much larger problem. An unsupported figure can affect the reliability of financial statements, create problems during audits, delay tax filings, distort management decisions, complicate the sale of a business, and potentially hide errors or irregularities.

This article explains what can happen when a business cannot explain a number in its financial statements, why these unexplained balances occur, how accountants investigate them, and what business owners can do to prevent the problem from happening again.

 

Why Every Number in the Financial Statements Should Be Explainable

Financial statements are summaries of thousands, and sometimes millions, of individual transactions. The income statement, balance sheet, and statement of cash flows do not simply contain numbers that appear at random. Each figure should ultimately be supported by underlying accounting records.

For example, if a business reports $250,000 in accounts receivable, the accounting records should be able to show which customers owe the money, how much each customer owes, and why the balance remains outstanding.

If the balance sheet shows $75,000 in equipment, the business should generally be able to identify the assets included in that amount and understand how the balance was calculated after purchases, disposals, and depreciation.

The same principle applies throughout the accounting system. A number should be traceable through a clear chain of evidence.

• The financial statement shows the summarized balance.
• The general ledger shows the account activity.
• The account activity leads to individual journal entries.
• The journal entries should be supported by invoices, receipts, contracts, bank records, payroll reports, reconciliations, or other evidence.

This process is sometimes described as an audit trail. Even if a business is not required to have an external audit, maintaining a clear trail from a reported number back to the original transaction is an important part of reliable bookkeeping.

When that trail breaks, the business has a problem. The issue may be minor, such as a missing receipt for a small expense. However, if the business cannot explain a large or material balance, the consequences can be much more serious.

 

The First Question: Is the Number Wrong or Simply Poorly Documented?

An unexplained number does not automatically mean that the financial statements are incorrect. Sometimes the transaction was legitimate, but the documentation or explanation has been lost over time.

For example, a company may have recorded a loan from an owner several years ago. The balance still appears in the books, but the current accounting staff cannot find the original loan agreement or supporting bank records.

The amount may still be correct. However, the business now has to prove that the balance is legitimate.

In other situations, the unexplained number is actually the result of an accounting error. It may have been caused by:

• A transaction being posted to the wrong account.
• A duplicated journal entry.
• A bank transaction being recorded twice.
• An old balance being carried forward incorrectly.
• A reconciliation adjustment that was never properly documented.
• An incorrect opening balance during a software conversion.
• A journal entry posted to force the books to balance.
• An account that was never reconciled correctly.

The longer an unexplained number remains in the accounting system, the more difficult it can become to determine which explanation is correct.

 

How an Unexplained Number Can Affect Financial Statements

Financial statements are connected. A problem in one account can eventually affect several other areas of the business.

Suppose a company cannot explain why its inventory account contains an additional $100,000. If the inventory balance is overstated, total assets may also be overstated. Depending on how the transaction was originally recorded, cost of goods sold and net income may also be incorrect.

Similarly, an unexplained liability could cause the business to understate or overstate its actual obligations.

This matters because financial statements are used for important decisions. Business owners may rely on them when deciding whether to hire employees, purchase equipment, expand into a new market, or distribute profits. Banks may review them when considering financing. Potential buyers may use them when valuing the company.

If the underlying numbers cannot be explained, the people relying on those statements may be making decisions using incomplete or inaccurate information.

 

The Problem Often Starts With an Old Balance

Many unexplained numbers are not created by a recent transaction. Instead, they develop quietly over several years.

Consider an account with a balance of $42,500. The account has not changed significantly in five years, and nobody currently working for the company knows why the balance exists.

Each year, the balance is carried forward because nobody wants to make an adjustment without understanding what happened. Eventually, the original transaction becomes increasingly difficult to investigate.

Employees leave. Accounting software changes. Bank records become harder to access. Supporting documents are misplaced. The original explanation disappears.

At that point, the unexplained balance has effectively become an accounting mystery.

This is one reason why regular reconciliations and periodic account reviews are so important. Problems are generally easier to resolve when they are discovered shortly after the original transaction.

 

What Accountants Do When They Cannot Explain a Number

When an accountant encounters an unexplained figure, the goal is usually not to guess. The goal is to reconstruct the history of the account and identify the underlying transaction or transactions.

The investigation often begins with the general ledger.

 

Step 1: Identify the Exact Account and Balance

The accountant first determines exactly what is unexplained.

Is the problem the entire account balance, or only one unusual transaction within the account?

For example, an accounts payable balance may generally be correct, but one supplier credit may have remained outstanding for three years. Alternatively, the entire balance may be impossible to reconcile to supporting records.

Defining the problem clearly makes the investigation more manageable.

 

Step 2: Review the General Ledger History

The next step is often to review the transaction history for the account.

The accountant may look for:

• The date when the balance first appeared.
• The journal entry or transaction that created it.
• The person or system that recorded the entry.
• Any unusual adjustments.
• Changes in the balance over time.
• References to invoices, bank transactions, or other source documents.

Sometimes the investigation quickly identifies the source of the problem. A journal entry may contain a useful memo, reference number, or attachment.

In other cases, the ledger provides very little information. The accountant may see only a vague description such as “adjustment,” “opening balance,” or “miscellaneous entry.”

Those vague descriptions can make future investigations significantly more difficult.

 

Step 3: Trace the Number Backward

Once the relevant transaction has been identified, the accountant attempts to trace it back to the original source.

This may involve reviewing:

• Bank statements.
• Invoices and bills.
• Customer records.
• Supplier statements.
• Payroll reports.
• Tax returns.
• Loan agreements.
• Asset purchase documentation.
• Previous financial statements.
• Prior-year working papers.
• Email correspondence.
• Accounting system attachments.

The objective is to establish a reasonable explanation supported by evidence.

 

This process is closely related to the way accountants investigate accounting errors. If you are interested in how professionals follow a discrepancy through the accounting records, you can also read our article on how accountants trace an error back to its original transaction.

 

Reconciliations Often Reveal the Problem

A reconciliation compares an accounting balance with an independent source of information. This process can reveal whether the number shown in the books is actually supported.

Bank reconciliations are one of the most familiar examples. The cash balance in the accounting system should be reconciled to the bank statement, after considering legitimate timing differences such as outstanding checks or deposits in transit.

However, the same principle applies to many other accounts.

• Accounts receivable can be reconciled to customer balances.
• Accounts payable can be reconciled to supplier records.
• Payroll accounts can be reconciled to payroll reports.
• Inventory can be reconciled to physical counts and inventory systems.
• Fixed assets can be reconciled to an asset register.
• Loans can be reconciled to lender statements and agreements.

If an account cannot be reconciled, that does not necessarily prove fraud or a major error. It does, however, indicate that additional investigation is necessary.

 

What Happens During an Audit or Financial Review?

An unexplained number can become particularly important when the financial statements are reviewed or audited.

Accountants performing assurance work generally need evidence supporting significant balances and transactions. If a company cannot provide sufficient evidence, the accountant may need to perform additional procedures or consider whether the lack of evidence affects the reliability of the financial statements.

For example, if a company reports a significant receivable but cannot identify the customer or provide documentation showing that the amount is collectible, the reported asset may need further investigation.

The problem is not simply that someone asked an inconvenient question. The issue is whether sufficient evidence exists to support the amount reported.

A lack of documentation can create several consequences:

• Additional time may be required to investigate the balance.
• The cost of accounting or audit work may increase.
• Management may need to reconstruct historical records.
• Adjustments may be required.
• The reliability of other accounts may receive additional scrutiny.
• In some circumstances, the accountant may be unable to obtain sufficient evidence for a particular balance.

The wider issue is trust. If one major number cannot be explained, reviewers may reasonably ask whether other numbers in the financial statements are also unsupported.

 

An Unexplained Number Can Create Tax Problems

Tax calculations are often based on financial information. If the underlying accounting records are incomplete or inaccurate, tax reporting may also be affected.

For example, an unexplained expense may not be supported by sufficient documentation. An unexplained liability may affect deductions. A missing explanation for revenue could raise questions about whether income was recorded correctly.

The exact consequences depend on the facts, the jurisdiction, and the nature of the transaction. However, from a practical perspective, poor documentation can make it more difficult for a business and its advisors to support the positions taken in tax filings.

Maintaining organized financial records is therefore not just an accounting exercise. It can also make tax compliance more efficient and reduce the time required to answer questions about historical transactions.

 

Management Decisions Can Be Based on the Wrong Information

One of the most overlooked consequences of unexplained numbers is the effect on everyday business decisions.

Imagine that a business believes it has $500,000 in working capital. Management may use that information when planning expansion, purchasing inventory, or deciding whether additional financing is necessary.

But if $100,000 of the reported assets cannot be explained or collected, the company may have substantially less financial flexibility than management believes.

Likewise, an understated liability could create a false impression that the company is more profitable or financially stable than it actually is.

Reliable accounting records support better decision-making. Unexplained balances reduce the reliability of the information being used.

 

The Issue Can Become Serious When Selling a Business

Business owners often discover accounting problems during a sale, merger, investment process, or due diligence review.

A potential buyer will typically want to understand the financial condition of the business. If the balance sheet contains accounts that cannot be explained, the buyer may question the quality of the company’s financial reporting.

For example, a buyer may ask:

• What makes up this accounts receivable balance?
• Why has this liability remained unchanged for several years?
• Can you provide documentation for this asset?
• Why does this account not reconcile to supporting records?
• What is the purpose of this recurring journal entry?

If management cannot answer these questions, the transaction may take longer. The buyer may request additional analysis, reduce the proposed valuation, require adjustments, or become concerned about other areas of the financial statements.

Cleaning up unexplained balances before entering a transaction can therefore be an important part of financial preparation.

 

Could an Unexplained Number Indicate Fraud?

An unexplained number does not automatically mean fraud has occurred. Most accounting discrepancies have more ordinary explanations, such as mistakes, missing documentation, poor processes, or problems during a software conversion.

However, unexplained balances should not simply be ignored.

Fraud and financial misconduct often involve attempts to conceal transactions, manipulate balances, or create misleading accounting records. An unsupported journal entry or unusual adjustment may therefore require additional attention, particularly if other warning signs are present.

Potential warning signs may include:

• Large or unusual manual journal entries.
• Transactions recorded near the end of a reporting period without clear explanations.
• Repeated adjustments to the same account.
• Missing documentation.
• Transactions involving related parties that are not clearly documented.
• Balances that remain unresolved for extended periods.
• Employees who are unwilling or unable to explain transactions they recorded.

The appropriate response is to investigate the evidence rather than assume the explanation. Depending on the circumstances, the business may need assistance from experienced accounting, audit, legal, or forensic professionals.

 

Why “Plug” Entries Can Make the Problem Worse

One of the most dangerous ways to deal with an unexplained number is to simply post another unexplained number.

For example, imagine that an accountant discovers the books are out of balance or an account cannot be reconciled. Instead of identifying the cause, someone posts an entry to a miscellaneous account just to make the numbers appear correct.

This is sometimes informally referred to as a plug or forced adjustment.

The immediate problem may appear to disappear, but the underlying issue remains. The business has effectively replaced one unexplained number with another.

Over time, these adjustments can accumulate. The general ledger becomes increasingly difficult to understand, and future accountants may spend significant time trying to reconstruct what happened.

A better approach is to identify the underlying cause and document the conclusion, even when the resolution requires an adjusting entry.

 

Sometimes the Correct Solution Is to Write Off or Adjust the Balance

Not every unexplained number can be fully reconstructed. In some cases, the available records may be insufficient to determine exactly what happened.

When this occurs, the business may eventually need to make an accounting adjustment.

However, the adjustment should not be made casually. Management and its accounting advisors should first perform a reasonable investigation, consider the available evidence, evaluate the potential impact, and document why the adjustment is appropriate.

For example, an old receivable may be written off if the company determines that it is no longer collectible and no reliable evidence supports continued recognition as an asset.

An old liability may require investigation to determine whether the obligation still exists. A suspense balance may need to be cleared after identifying the underlying accounting issue.

The key principle is that the resolution should improve the accuracy and transparency of the financial statements rather than simply hide the problem.

 

How to Prevent Unexplained Numbers From Building Up

The best time to investigate an unusual number is usually when it first appears.

Businesses can reduce the risk of unexplained balances by establishing consistent accounting processes.

 

1. Reconcile Important Accounts Regularly

Bank accounts should be reconciled regularly, but businesses should not stop there. Other significant balance sheet accounts should also be reviewed and reconciled to supporting information where appropriate.

Regular reconciliations make it easier to identify discrepancies while records and documentation are still available.

 

2. Require Clear Documentation for Journal Entries

Manual journal entries should contain meaningful descriptions and appropriate supporting documentation.

A future accountant should be able to understand what the entry represents without having to guess.

Instead of a vague description such as “adjustment,” a clearer explanation might identify the purpose of the entry and reference the supporting calculation or documentation.

 

3. Review Old and Inactive Balances

Accounts that have remained unchanged for long periods should be reviewed periodically.

Old balances are often easier to resolve before the people involved leave the company or the original documents become unavailable.

 

4. Avoid Using Suspense or Miscellaneous Accounts as Permanent Storage

Suspense accounts can be useful temporary tools when a transaction cannot immediately be classified correctly. However, they should not become permanent destinations for unexplained transactions.

Items in these accounts should be investigated and cleared as soon as practical.

 

5. Maintain a Strong Month-End Close Process

A structured month-end close process helps businesses identify problems before they accumulate.

A typical review may include:

• Reconciling bank accounts.
• Reviewing accounts receivable aging.
• Reviewing accounts payable aging.
• Investigating unusual account movements.
• Reviewing manual journal entries.
• Comparing results with previous periods.
• Reviewing old or inactive balances.
• Confirming that major accounts have supporting schedules.

Businesses that follow a disciplined close process are more likely to identify errors before they become long-term problems.

 

The Importance of Good Bookkeeping

Many serious accounting problems begin with relatively small bookkeeping issues.

A transaction is posted to the wrong account. A receipt is not saved. A reconciliation is skipped. A journal entry lacks an explanation. A software conversion begins with inaccurate opening balances.

Individually, each issue may seem manageable. Over time, however, they can create a financial reporting system that becomes increasingly difficult to trust.

Good bookkeeping provides the foundation for reliable financial information. It helps ensure that transactions are recorded consistently, supporting documentation is retained, and account balances can be explained when questions arise.

What Business Owners Should Ask When Reviewing Their Financial Statements

Business owners do not need to become accountants to ask useful questions about their financial information.

When reviewing financial statements, consider asking:

• Can this major balance be supported by a schedule or reconciliation?
• What caused this account to increase or decrease?
• Are there any old balances that have not changed for an unusual amount of time?
• Are there transactions sitting in suspense or miscellaneous accounts?
• Are there large manual journal entries that require explanation?
• Does the reported cash balance agree with reconciled bank records?
• Can significant receivables and payables be identified individually?
• Are there any balances that management does not understand?

These questions can help identify problems before an outside accountant, lender, buyer, or auditor discovers them.

 

When Should a Business Ask for Professional Help?

Some accounting discrepancies can be resolved internally. Others may require additional expertise.

Professional assistance may be particularly valuable when:

• The unexplained balance is significant.
• The issue involves multiple years of accounting records.
• Financial statements are required for financing or a business transaction.
• Tax reporting may be affected.
• The business suspects significant errors or irregularities.
• A software conversion created unexplained opening balances.
• Management needs help reconstructing historical accounting records.

An experienced accounting professional can help review the general ledger, reconcile accounts, trace transactions, identify potential errors, and document the conclusions reached during the investigation.

Final Thoughts

A business should be able to explain the significant numbers in its financial statements.

That does not mean every transaction will be perfect or that every historical accounting issue can be solved instantly. Errors happen. Documentation can be lost. Accounting systems can change. Employees and advisors can come and go.

What matters is how the business responds when a number cannot be explained.

The right response is to investigate the balance, trace the available evidence, review the accounting records, perform reconciliations, and document the conclusion. If an adjustment is necessary, it should be based on a reasonable analysis rather than an attempt to simply make the problem disappear.

Unexplained numbers can be more than accounting inconveniences. They can affect financial reporting, tax compliance, lending, business valuation, management decisions, and confidence in the company’s records.

Ultimately, reliable financial statements depend on a simple principle: every significant number should have a clear explanation.

When a business can trace a number back to the transactions and evidence that created it, the financial statements become more useful, more reliable, and easier to defend when questions arise.
