Why Your Profit and Loss Statement Changes After Your Accountant Reviews It

 

It can be surprising to look at your profit and loss statement at the end of the month or financial year and then discover that the numbers have changed after your accountant reviews them. Revenue may be slightly different, expenses may have moved between categories, and your final profit could be higher or lower than the figure you originally saw. For business owners, this can sometimes create confusion. If the transactions were already entered into the accounting software, why did the profit and loss statement need to change? In most cases, these changes do not mean that something has gone wrong. Instead, they are often the result of accounting adjustments that make the financial statements more accurate and ensure income and expenses are recorded in the correct accounting period. An accountant’s review can identify transactions that have been incorrectly classified, expenses that belong to a different period, income that has not yet been recognised, depreciation that needs to be recorded, or other adjustments that are necessary before the accounts are finalised. Understanding why these adjustments happen can help business owners become more comfortable with the accounting process and better understand what their profit and loss statement is actually telling them.

 

What Is a Profit and Loss Statement?

 

A profit and loss statement, often called a P&L or income statement, summarises a business’s income, costs and expenses over a specific period. It is one of the most important financial reports used to assess business performance. At its simplest, the calculation is:

 

Revenue − Expenses = Profit or Loss

 

If a business generates £250,000 of revenue and has £190,000 of expenses during the relevant accounting period, the initial profit figure would appear to be £60,000. However, that does not necessarily mean £60,000 is the final accounting profit. Before financial statements are finalised, an accountant may review the underlying transactions and identify adjustments that change either revenue or expenses. For example, the business may have paid a twelve-month insurance policy in advance. If the entire payment was initially recorded as an expense, the P&L could show expenses that are too high for the current period. An accountant may allocate only the portion relating to the current period to the P&L and treat the remaining amount as a prepayment on the balance sheet. This is one reason why the figure you see in your accounting software before year-end adjustments may differ from the final profit reported by your accountant.

 

Why Does Your Profit and Loss Statement Change After an Accountant’s Review?

 

The main reason is that bookkeeping and financial reporting are not always exactly the same process. Day-to-day bookkeeping records transactions as they occur, while an accountant’s review can involve adjusting those transactions so that the financial statements more accurately reflect the business’s financial position and performance. An accountant may review the accounts for accuracy, completeness, classification and timing. They may also consider accounting principles and the information needed to prepare year-end accounts.

Common adjustments include:

• Accrued expenses
• Prepaid expenses
• Depreciation
• Bad debt adjustments
• Deferred or unearned income
• Inventory adjustments
• Incorrectly classified transactions
• Bank and balance sheet reconciliations
• Director or shareholder transactions
• Corrections to previous bookkeeping errors
• Year-end journals

These adjustments can change the final profit without necessarily changing the amount of cash that entered or left the business.

 

Bookkeeping Profit Is Not Always Final Accounting Profit

 

One of the most important distinctions for business owners is that the profit displayed in accounting software is not automatically the final profit figure for the financial statements. Cloud accounting systems make it relatively easy to record invoices, bills, payments and receipts. However, accounting reports depend on how those transactions have been entered, categorised and dated. A bookkeeping system might initially show a business with a profit of £75,000. After reviewing the accounts, an accountant might record £8,000 of depreciation, £3,000 of accrued expenses and a £2,000 correction for an expense that had previously been omitted.

The revised profit would be:

 

£75,000 − £8,000 − £3,000 − £2,000 = £62,000

 

The business did not suddenly lose £13,000 of cash. Instead, the accounting records were adjusted to provide a more accurate representation of the period’s financial performance.

 

Accrued Expenses Can Reduce Your Profit

 

Accruals are one of the most common reasons a P&L statement changes after an accountant reviews the accounts. An accrued expense occurs when a business has received goods or services during an accounting period but has not yet received or paid the corresponding invoice. Imagine a company receives professional services in December but does not receive the invoice until January. If the business only records expenses when invoices are received, the December P&L may initially show too much profit. An accountant may recognise the expense in December because that is when the service was actually received. This means the expense is included in the appropriate accounting period, even though the cash payment occurs later.

For example:

• Initial December profit: £50,000
• December professional fees accrued: £4,000
• Adjusted December profit: £46,000

The adjustment makes the P&L more representative of the costs associated with generating December’s revenue.

 

Prepayments Can Increase Reported Profit

 

The opposite situation can occur with prepaid expenses. A prepayment occurs when a business pays for something before it receives the related benefit. Common examples include insurance, software subscriptions, rent and service contracts. Suppose a company pays £12,000 for a twelve-month insurance policy in October. If the entire £12,000 is initially recorded as an expense in October, the P&L may show an unusually large expense for that month. An accountant may determine that only three months of the policy relate to the current financial year. The remaining amount can be treated as a prepayment and recognised as an expense in the future periods to which it relates. As a result, the final P&L may show lower expenses and higher profit than the original bookkeeping report.

 

Depreciation Can Change Your Profit

 

Depreciation is another common year-end adjustment. When a business purchases a long-term asset such as equipment, machinery, furniture or certain technology, the full purchase price is not necessarily treated as an expense immediately for accounting purposes. Instead, the cost may be allocated over the asset’s useful economic life through depreciation. For example, if a company purchases equipment for £30,000 and the accounting treatment results in £6,000 of depreciation for the year, the accountant may record a £6,000 depreciation expense. If depreciation had not previously been recorded in the bookkeeping reports, the final P&L would show lower profit after the accountant makes the adjustment. Depreciation can therefore make a significant difference to reported accounting profit, even though the depreciation entry itself is not a current cash payment.

 

Incorrectly Categorised Transactions May Be Reclassified

 

Another common reason for changes to a P&L statement is incorrect transaction classification. Accounting software often gives users a range of categories to choose from. A transaction can easily be assigned to the wrong account, particularly when the business has many transactions or the description on a bank statement is unclear. For example, a £5,000 payment for new office equipment might initially be recorded as office expenses. During the accountant’s review, it may be determined that the purchase should instead be recorded as an asset. This can change the P&L because the original £5,000 expense may be removed and replaced with the appropriate depreciation charge.

Other examples of transactions that may be reclassified include:

• Business loan repayments
• Asset purchases
• Bank charges
• Professional fees
• Director transactions
• Travel expenses
• Personal expenses paid through a business account
• VAT-related transactions

Reclassification does not always mean that the transaction itself was wrong. Sometimes it simply means it was originally posted to an account that was not the most appropriate classification.

 

VAT Can Also Affect the Numbers You See

 

VAT treatment can create differences between bookkeeping records and final accounts, depending on how transactions have been recorded and the accounting method being used. For VAT-registered businesses, it is important to distinguish between the gross transaction value, VAT and the amount that ultimately belongs in the income statement. If VAT has been incorrectly included in an income or expense account, an accountant may correct the classification during their review. This can make revenue or expenses appear different from the figures a business owner originally expected. VAT adjustments can be particularly important when reviewing year-end accounts because errors in VAT coding may affect both the P&L and balance sheet.

 

Bad Debts Can Reduce Profit

 

A business may issue invoices and record revenue even though some customers ultimately fail to pay. During an accounts review, an accountant may examine outstanding receivables and identify amounts that are unlikely to be recovered. Depending on the circumstances and applicable accounting treatment, an adjustment may be required for doubtful or irrecoverable debts. This can increase expenses or reduce the amount of receivables recognised, which can in turn reduce reported profit. For example, if a business has £100,000 of outstanding customer invoices but £6,000 is considered unlikely to be recovered, an appropriate accounting adjustment may affect the reported figures. This is another example of why the profit shown before the accountant’s review may not be the final number.

 

Inventory Adjustments Can Change Gross Profit

 

Businesses that hold inventory may also see significant changes after year-end adjustments. Inventory affects the relationship between purchases, cost of sales and gross profit. If the inventory figure in the accounting records does not agree with the actual or properly assessed closing inventory, an adjustment may be required. For businesses that buy and sell physical goods, even a relatively small inventory adjustment can affect gross profit and therefore overall profit. For example, if the accounts initially suggest that closing inventory is £40,000 but a properly prepared stock valuation results in a different figure, the cost of sales and profit may need to be adjusted. This is why inventory counts and accurate stock records can be important parts of the year-end accounting process.

 

Accountants May Find Transactions Missing From the Books

 

Not every accounting adjustment involves changing an existing transaction. Sometimes an accountant discovers that a transaction has not been recorded at all.

This can happen for several reasons.

• An invoice was received but never entered into the accounting system.
• A bank transaction was missed during reconciliation.
• A recurring expense was not recorded.
• A customer invoice was omitted.
• An asset purchase was not correctly entered.
• A year-end expense had not yet been invoiced.

If a missing expense is discovered, the final profit may decrease. If missing revenue is identified, the final profit may increase. These adjustments can be particularly important because financial statements need to reflect all relevant transactions for the accounting period, not simply the transactions that happened to be entered into the bookkeeping software.

 

Year-End Journals Can Make the P&L Look Different

 

Many accountants use journal entries to record adjustments at the end of an accounting period. A journal allows an accountant to make a controlled adjustment between accounting accounts without creating a new bank transaction.

Examples include journals for:

• Accruals
• Prepayments
• Depreciation
• Provisions
• Inventory
• Deferred income
• Corrections
• Reclassifications

When these journals are posted, the P&L automatically changes because the underlying account balances have changed. This can sometimes make it appear as though an accountant has simply changed the profit figure. In reality, the accountant has usually changed specific underlying accounts, and the revised profit is the result of those adjustments.

 

Why Accountants Review the P&L in the First Place

 

An accountant’s review is not simply about checking whether the final profit looks reasonable. It involves examining whether the financial records have been prepared appropriately and whether the accounts provide a reliable picture of the business. An accountant may compare the P&L against previous periods, investigate unusual movements and review individual account balances. For example, if advertising expenses suddenly increase by 300% compared with the previous year, the accountant may investigate whether the increase is genuine or whether transactions have been incorrectly categorised. Likewise, if gross profit margins change significantly, the accountant may examine revenue, purchases and inventory to understand why. The purpose is to identify inconsistencies before the accounts are finalised.

 

Common P&L Changes You Might See After a Review

 

Business owners may notice several types of changes after an accountant reviews their accounts.

 

Revenue Changes

Revenue may change if invoices were omitted, duplicated, recorded in the wrong period or incorrectly classified. Deferred income may also need to be recognised over the appropriate period rather than all at once.

Cost of Sales Changes

Businesses that sell products may see changes to cost of sales because of inventory adjustments, purchase corrections or the reclassification of certain costs.

Operating Expense Changes

Expenses may change because of accruals, prepayments, depreciation, corrections or reclassification.

Profit Changes

Once revenue and expenses have been adjusted, the final profit or loss changes automatically. Importantly, a change in reported profit does not necessarily mean that the business’s cash balance changed by the same amount.

Profit and Cash Are Not the Same Thing

 

This is one of the most important concepts for business owners to understand. Profit is an accounting measure of financial performance. Cash represents the money available in the business’s bank accounts and other cash resources.

A business can be profitable but have limited cash. It can also have significant cash in the bank while reporting a lower accounting profit.

Depreciation is a straightforward example. Depreciation can reduce accounting profit without creating a new cash payment in the current period.

Accruals provide another example. An expense can reduce accounting profit even though the corresponding cash payment has not yet been made.

This distinction is why business owners should avoid assuming that every P&L adjustment represents money physically leaving or entering the bank account.

 

When a Change May Indicate a Genuine Bookkeeping Error

 

Although adjustments are normal, accountants can also identify genuine bookkeeping errors during a review.

Examples include:

• Duplicate invoices
• Duplicate expenses
• Transactions posted to the wrong account
• Personal purchases recorded as business expenses
• Bank transactions that were not reconciled
• Incorrect invoice dates
• VAT coding errors
• Assets incorrectly treated as expenses
• Loans incorrectly recorded as income

Correcting these errors can materially change the P&L, especially if the issue occurred repeatedly throughout the year.

 

How to Understand the Changes Your Accountant Made

 

If your final P&L looks different from the version you originally reviewed, the best approach is to ask for an explanation of the adjustments rather than assuming something has gone wrong. Your accountant should be able to explain the material changes and identify the accounts affected.

You can ask questions such as:

• Which adjustments changed the profit figure?
• Were any transactions reclassified?
• Were accruals or prepayments recorded?
• Was depreciation added?
• Were any bad debts adjusted?
• Was inventory changed?
• Were any missing transactions identified?
• Did any adjustments relate to previous periods?

Understanding these adjustments can help you improve your bookkeeping processes for the following year.

 

How Better Bookkeeping Can Reduce Year-End Adjustments

 

While some year-end adjustments are completely normal, maintaining accurate and organised bookkeeping throughout the year can reduce the number of corrections required. Business owners can improve their records by reconciling bank accounts regularly, keeping supporting documentation, reviewing aged receivables and payables, and ensuring transactions are categorised consistently. It can also be useful to review your P&L monthly rather than waiting until the end of the financial year. Regular reviews can help identify unusual transactions early. If office expenses suddenly double, for example, investigating the change immediately is usually easier than trying to understand it twelve months later.

 

Why Monthly P&L Reviews Matter

 

A monthly P&L review gives business owners an opportunity to identify trends before they become larger problems.

Useful questions include:

• Is revenue increasing or decreasing?
• Are gross margins stable?
• Which expenses are increasing?
• Are there unusual transactions?
• Are customer debts increasing?
• Are costs consistent with the business’s activity?
• Are there transactions that need further investigation?

Regular management accounts can also make year-end accounting smoother because many issues are identified before the accountant begins the final review.

 

What Business Owners Should Expect From an Accountant’s Review

 

An accountant’s review should provide greater confidence in the financial information being used to make business decisions and prepare financial statements. Depending on the engagement and the type of accounts being prepared, the accountant may review balance sheet accounts, reconcile balances, assess year-end adjustments and investigate unusual transactions. The exact work performed will depend on the business, its accounting records and the services being provided. For business owners, the important point is that the final P&L is often the result of more than simply adding up the transactions entered throughout the year.

 

What You Can Learn From Changes to Your P&L

 

Changes made during an accountant’s review can provide useful information about the quality of your accounting processes. If your accountant regularly has to correct the same types of transactions, that may indicate that your bookkeeping system or internal procedures could be improved. For example, repeated corrections involving personal expenses may indicate that business and personal spending should be separated more carefully. Frequent VAT corrections may suggest that transaction coding needs greater attention. Repeated missing invoices may indicate that supplier documents need to be collected and processed more systematically. In this way, an accountant’s review can be more than a year-end exercise. It can highlight opportunities to improve the financial management of the business.

 

How an Accountant Helps Turn Bookkeeping Data Into Useful Financial Information

 

Modern accounting software can automate many bookkeeping tasks, but software does not eliminate the need for accounting judgement. The system can record transactions, produce reports and reconcile certain information. However, someone still needs to determine whether transactions have been recorded appropriately and whether the resulting financial statements accurately reflect the relevant period. This is where professional accounting review can add value. An accountant can examine the bigger picture rather than simply looking at individual transactions. They can consider how different accounts interact and whether the overall financial statements make sense.

Frequently Asked Questions About P&L Adjustments

 

Why did my profit decrease after my accountant reviewed my accounts?

Your profit may decrease because your accountant identified additional expenses, accrued costs, depreciation, bad debts, inventory adjustments or bookkeeping errors. The adjustment does not necessarily mean cash has left the business.

Can my profit increase after an accountant reviews my accounts?

Yes. Profit can increase if expenses were initially overstated, prepayments are identified, duplicate expenses are removed or income that should have been recognised is added to the accounts.

Are accountant adjustments normal?

Yes. Adjustments are a normal part of preparing and reviewing financial statements. Some adjustments are necessary to account for timing differences, while others correct classification or bookkeeping issues.

Why does depreciation change my profit?

Depreciation allocates the cost of certain long-term assets over their useful economic lives for accounting purposes. It can therefore reduce accounting profit without representing a current-period cash payment.

Should I be worried if my accountant changes my P&L?

Not automatically. The important thing is to understand why the changes were made. Ask your accountant to explain significant adjustments and how they affect your financial statements.

Is the P&L in my accounting software always accurate?

The report is only as reliable as the underlying records and accounting treatment. Accounting software can produce accurate calculations from the information entered, but it cannot always determine whether every transaction has been classified, timed or adjusted appropriately.

 

Final Thoughts

 

Seeing your profit and loss statement change after your accountant reviews it can initially be confusing, but it is often a normal part of the accounting process. Accruals, prepayments, depreciation, inventory adjustments, bad debts, reclassifications and corrections can all affect the final figures. These adjustments are designed to ensure that revenue and expenses are reported in the appropriate periods and that the financial statements provide a more accurate picture of the business. The key is to remember that your first bookkeeping report and your final financial statements may serve different purposes. A preliminary P&L gives you useful information about business performance, while an accountant’s review adds another layer of analysis and adjustment before the accounts are finalised. If your P&L changes after review, do not simply focus on whether the final profit is higher or lower. Look at why it changed. Understanding the adjustments can help you identify weaknesses in your bookkeeping, improve your financial processes and make better-informed decisions in the future.
