Bookkeeping Cleanup: A Complete Guide to Fixing Messy Business Books
Bookkeeping Cleanup: A Complete Guide to Fixing Messy Business Books Introduction It does not necessarily mean your books need to lag for several years before being difficult to manage. The existence of a couple of bank transactions without reconciliation, duplicate entries, wrongly classified expenses, unpaid invoices, or outstanding balances could eventually create an even more serious accounting issue. By the time this is noticed, it might already be difficult for business owners to see what their real cash position, profit, or expenses are. This is where bookkeeping cleanup comes in. Bookkeeping cleanup refers to the activity of checking accounting records and cleaning them up before creating any financial reports. This is not like adding new transactions in the books. Bookkeeping cleanup involves a backward process that seeks to discover what was wrong with the previous entries in order to rectify it and establish a better ground to build on. In this tutorial, we shall discuss the basics of bookkeeping cleanup, the most common challenges that companies encounter, a checklist of the cleanup process, and when to consider using bookkeeping services. What Is Bookkeeping Cleanup? Bookkeeping reconciliation is an organized activity aimed at fixing, organizing, and reconciling accounting records that have been found to be faulty and hard to understand. A cleanup may involve reviewing: Bank accounts Credit card accounts Accounts receivable Accounts payable Income transactions Business expenses Payroll-related entries Loans and liabilities Fixed assets Owner or shareholder transactions Uncategorized transactions Suspense accounts Duplicate transactions Opening balances Financial statements The exact work depends on how far the books have fallen behind and what problems exist in the accounting records. For example, a business may have six months of unreconciled bank transactions. Another business may have accurate bank records but hundreds of incorrectly categorized expenses. While both instances need cleaning up, the methods will be distinct. Why Do Business Books Become Messy? Generally, messy books never arise suddenly. Rather, they tend to result from the delay in doing the accounting work as the company is busy with its sales and other activities. Common causes include: Missed Bank Reconciliations If bank accounts are not reconciled regularly, differences between the accounting system and actual bank activity can remain unnoticed. Uncategorized Transactions Bank feeds can create large numbers of transactions that remain uncategorized. Over time, these transactions make financial reports less useful. Duplicate Transactions Manual entries combined with imported bank transactions can sometimes result in duplicate records. Incorrect Expense Categories An expense may be recorded, but under the wrong account. This can distort the business’s profit and loss reporting. Missing Invoices or Bills When invoices, bills, or receipts are missing from the accounting system, accounts receivable and accounts payable may not represent the actual position of the business. Personal and Business Transactions Mixed Together When personal transactions are recorded through business accounts without proper classification, reviewing the books becomes more complicated. Accounting Software ChangesCompanies often change from one accounting system to another. This transition process can be difficult for companies and lead to the need for an audit if not managed effectively. 10 Signs You May Need to Tidy Up Your Bookkeeping Not sure whether your books need attention? Look for these warning signs. Bank Accounts Are Not Reconciled If your accounting software balance does not match your bank statements, the books should be investigated. Large Number of Uncategorized Transactions A growing uncategorized or suspense balance can indicate that transactions have not been properly reviewed. Your Profit Doesn’t Look Right If the reported profit seems completely different from what you expected based on sales and expenses, incorrect classifications or missing transactions may be involved. Accounts Receivable Doesn’t Match Reality Your accounting system may show customers owing money even though some invoices have already been paid. Accounts Payable Contains Old Balances Old vendor balances can indicate missing payments, duplicate bills, incorrect entries, or accounts that need review. No Reconciliation Is Done on Credit Card Accounts It becomes hard to keep track of transactions involving credit cards when these do not get entered consistently. Your Accountant Keeps Finding the Same Errors Repeated corrections during tax preparation or financial review may indicate an underlying bookkeeping process problem. Financial Reports Take Too Long to Prepare If generating a reliable P&L or Balance Sheet requires significant manual work every month, the underlying bookkeeping system may need attention. You Are Preparing for a Tax Filing Tax preparation becomes more efficient when the underlying books have already been reviewed and reconciled. You Cannot Easily Explain Your Numbers This is perhaps the biggest warning sign. If someone asks, “Why is this expense so high?” or “Why does this balance appear on the Balance Sheet?” and nobody can confidently explain it, your books may need a closer review. Bookkeeping Organizational Guide A systematic process makes cleanup easier. Following is a checklist that businesses can implement. Step 1: Gathering of Financial Information Gather the relevant: Bank statements Credit card statements Loan statements Sales records Purchase invoices Vendor bills Payroll records Payment processor reports Tax records Previous financial statements The exact documents required depend on the business and cleanup period.
