Written by Maximilian Straub | Published on November 8, 2025 | 10 min read

A guide to small business accounting explains the right way to record, review, and organize financial transactions. It shows business owners how to identify and reduce accounting errors. Also, the guide outlines steps to fix disorganized books and maintain accurate financial records.

Do you know how accounting errors occur in D2C companies? That’s largely due to:

  • Missed entries
  • Manual work
  • Changing tax rules
  • Every day operational pressure

Gradually, these small gaps distort cash flow visibility, tax calculations, and business performance metrics. This leads to increasing compliance risk + lower investor confidence. 

So, want to reduce errors and make your books clean? Read this article to learn about eight major steps through which you can fix your messy financial statements and reduce accounting errors.

How Common Are Accounting Errors? A Data-Backed Reality Check!

Remember that even experienced accounting teams make mistakes. These accounting errors do not come from a lack of knowledge, but from:

  • Workload pressure
  • Repeated manual work
  • Routine data entry

For more clarity, check out the statistics below showing how frequently errors happen and what causes them:

Area of Error What the Data Shows What It Means for Businesses
Daily financial errors 18% of accountants make errors every day Errors are not occasional; they can occur as part of daily work
Monthly error frequency 59% report multiple errors each month Mistakes accumulate over time if not corrected
Data entry error rate 4 errors per 100 entries Manual data entry errors lead to the formation of inferior financial statements
Cause of process failures 80% due to human error Most issues are people-driven (not system-driven)
Source of data errors 27.5% caused by manual input by finance staff Repetitive manual work increases error exposure

Want to prevent them? As a VP or director of a D2C company, you must try to understand “where” these errors occur and “how often”. Let’s understand better in the next section. 

How To Reduce Errors in 2026? 8 Steps from Guide to Small Business Accounting

Did you know? In 2024, U.S. public companies reached a nine-year high in financial restatements, with 140 firms forced to withdraw and reissue their financial statements in just the first ten months due to serious mistakes

This trend had already started earlier, with restatements increasing 11% in 2022, and it continues into 2025 as accounting rules and compliance requirements become more complex. The business impact? 

  • Distortion of profits
  • Poor performance metrics
  • Increased regulatory risk
  • Attraction of higher penalties

For growing D2C companies and consumer brands earning $5M+ revenue, the financial impact can be severe, with penalties averaging 5 to 10% of annual earnings. Don’t want that? Below is a guide to small business accounting, and some steps you must follow to reduce accounting errors in 2026:

Step 1: Collect Every Financial Record in One Place

A bookkeeping cleanup cannot start until all financial documents are gathered. This means pulling together:

  • Bank statements
  • Credit card statements
  • Sales invoices
  • Purchase bills
  • Expense receipts
  • Payroll records
  • Loan statements
  • Any other money-related documents

Furthermore, every account used for the business must be included, such as current accounts, savings accounts, credit cards, and loans. If even one account or period is missing, the books will not match reality. That again leads to:

  • Wrong balances
  • Incorrect profits
  • Problems during tax filing

Step 2: Check Each Transaction and Put It in the Right Category

Once all records are collected, the guide to small business accounting states that every transaction must be reviewed and assigned to the correct category, such as:

  • Rent
  • Salary
  • Marketing
  • Travel
  • Owner’s drawings

This step decides how your financial statements will look + what they will tell you about your business. If your accounting department uses any software (say QuickBooks or Xero), your bookkeeper must review all the transactions pulled from bank feeds and confirm or correct their categories

In contrast, if software is not used, transactions should be listed in spreadsheets and checked one by one.

Step 3: Find Missing, Duplicate, and Incorrect Transactions

The guide to small business accounting states that during a bookkeeping cleanup, it is normal to find transactions that do not match across records. But why does this happen? Some possible reasons are:

  • Some expenses may be recorded twice
  • Some may be missing
  • Others may show different amounts in bank statements and books

These issues usually come from lost receipts, unclear expense notes, or manual entry mistakes. In this step, your team should compare:

  • Bank statements
  • Receipts
  • Invoices
  • Accounting records line by line

Any mismatch must be flagged and traced back to its source.

Step 4: Confirm “Who Owes You” and “Whom You Owe”

Firstly, learn about these two terms:

  • “Accounts receivable” means money customers still need to pay you

and

  • “Accounts payable” means bills you still need to pay vendors.

Both directly affect how much cash is available in the business. Let’s see how errors in both segments are spotted:

For Receivables For Payables
  • All unpaid invoices are reviewed to confirm they are valid. 
  • Old invoices are discussed with the business owner to decide whether to
    “follow up” or “mark them as uncollectible”.
  • The vendor bills are checked to ensure they are real and:
    • Not duplicated 

or

  • Already paid
  • Any overpayments or incorrect charges are corrected.

Finally, these balances are matched with the general ledger so that the reports can show accurate cash obligations + expected receipts.

Step 5: Verify Payroll Payments and Tax Obligations

The guide to small business accounting states that after reconciling AP and AR, it’s time to confirm whether employees, taxes, and deductions are recorded correctly. Note that payroll records must reflect exactly what was paid to employees and contractors. Generally, this includes:

  • Salaries
  • Hourly wages
  • Bonuses
  • Overtime
  • Deductions
  • Employer contributions

Okay, but how to start this review? Ideally, it starts with payroll summaries, pay slips, and timesheets to confirm payments match approved amounts. Next, payroll expenses in the accounting system are matched with bank payments and reports from the payroll provider. 

This confirms that:

  • Salaries were paid
  • Taxes were withheld
  • Benefit contributions were processed

If your team finds any unpaid payroll taxes or statutory dues, it must be identified and recorded as liabilities.

Step 6: Match Bank + Credit Card Records with Your Books

“Reconciliation” is the process of checking whether the balances shown in your books match what the bank or card company reports. The process starts by confirming that opening balances match the statement. Each transaction on the statement is then compared with the accounting records.

As per the guide to small business accounting, the following are identified and corrected in this step:

  • Missing entries
  • Duplicate transactions
  • Wrong amounts

Usually, you would find some common gaps, such as bank charges, card fees, or payments that cleared in a later month. Every difference must be explained and resolved. The process ends when the closing balance in the accounting system matches the bank or credit card statement.

Step 7: Confirm All Taxes Are Recorded, Filed, and Paid

This step checks whether all tax-related records match actual filings and payments. To successfully execute it, your accounting department must review these tax areas:

Tax Area Reviewed What Is Checked? Why is it Important for Businesses?
Sales Tax Accuracy Correct tax rate on every taxable sale Prevents under- or over-collection of tax
Sales Tax Reporting Collected tax matches reported and paid amounts Avoids notices, interest, and penalties
Sales Tax Filings Unpaid or delayed filings are identified Reduces compliance risk and follow-up costs
Income Tax Records Income and expenses match the accounting books Ensures taxable income is not overstated
Deductible Expenses Missed or misclassified deductions are corrected Prevents paying more tax than required
Payroll Tax Filings Wages, deductions, and employer contributions match filings Protects against payroll tax penalties
Tax Payments Book balances match amounts actually paid Confirms no hidden tax liabilities exist
Statutory Forms TDS returns, 1099s, and sales tax reports are complete Ensures audit-ready documentation

This review confirms that taxes collected, reported, and paid all align with the business’s actual records.

Step 8: Review Financial Reports as a Final Accuracy Test

Lastly, the guide to small business accounting states that the cleanup is validated by reviewing key financial reports, such as:

  • The Profit and Loss statement, which confirms income and expenses.
  • The Balance Sheet, which confirms assets, liabilities, and equity balances. 
  • The Cash Flow Statement, which shows whether cash movement matches actual bank activity.

Your accounting team must review these reports for unusual figures such as negative balances, sharp cost spikes, or missing accounts. Any issue found here points back to a problem in earlier steps! Thus, corrections must be made until the reports align with supporting records.
