over a certain dollar amount
Matching up receiving reports based on actual counts and inspections of incoming shipments with purchase orders before approving checks for payment to suppliers
Requiring both a sales manager’s and another high-level manager’s approval for write-offs of customers’ overdue receivable balances (that is, closing the accounts on the assumption that they won’t be collected), including a checklist of collection efforts that were undertaken
Having auditors or employees who do not work in the warehouse take surprise counts of products stored in the company’s warehouse and compare the counts with inventory records
Requiring mandatory vacations by every employee, particularly bookkeepers and accountants, during which time someone else does that person’s job (because a second person may notice irregularities or deviations from company policies)
We don’t know of a computer database break-in for the purpose of manipulating or destroying accounting information — but a hacker could alter accounting information after breaking into a company’s information system. The topic of cybercrime is beyond the scope of this book, other than to warn you about this serious threat that requires a whole new set of internal controls. A new class of forensic professionals has emerged who advise and assist businesses in coming to grips with cyber threats. These specialists include both accountants and IT (information technology) experts.
Double-Entry Accounting
Businesses and nonprofit entities use double-entry accounting. But we’ve never met an individual who used double-entry accounting in personal bookkeeping. Instead, individuals use single-entry accounting. For example, when you write a check, process an electronic payment, or make a payment on your credit card balance, you undoubtedly make an entry in your checkbook to decrease your bank balance. And that’s it. You make just one entry — to decrease your checking account balance. It wouldn’t occur to you to make a second, companion entry to decrease your credit card liability balance. Why? Because you don’t keep a liability account for what you owe on your credit card. You depend on the credit card company to make an entry to decrease your balance.
$Assets = $Liabilities + $Capital + $Retained Earnings
The equal sign means that for every dollar of assets, there’s a dollar from one of the sources of assets on the right side of the accounting equation. Assets do not materialize out of nothing. Assets come from somewhere. There are three fundamental sources of assets: liabilities, capital invested in the business by its owners, and retained earnings (accumulated profit that has been earned but not distributed to its owners by the entity). Combining a business’s capital and retained earnings gives you its owners’ equity, or the net worth of the business.
The accounting equation is a condensed version of the balance sheet. The balance sheet is the financial statement that summarizes a business’s assets on the one side and its liabilities plus its owners’ equity on the other side. As we just mentioned, liabilities and owners’ equity are the sources of the business’s assets. Each source has different types of claims on the assets, which we explain in Chapter 7.
One main function of the bookkeeping/accounting system is to record all transactions of a business — every single last one. If you look at transactions through the lens of the accounting equation, there’s a beautiful symmetry in transactions (well, beautiful to accountants at least). All transactions have a natural balance. The sum of financial effects on one side of a transaction equals the sum of financial effects on the other side. Thus, the name of the balance sheet — because in theory, the balance sheet should always be, well, in balance.
Suppose a business buys a new delivery truck for $65,000 and pays by check (how old-fashioned is that?). The truck asset account increases by the $65,000 cost of the truck, and cash in the bank decreases $65,000. Here’s another example: A company borrows $2 million from its bank. Its cash in the bank increases by $2 million, and the liability for its note payable to the bank increases by the same amount.
Just one more example: Suppose a business suffers a loss from a tornado because some of its assets were not insured (dumb!). The assets destroyed by the tornado are written off (decreased to zero balances), and the amount of the loss decreases the owners’ equity by the same amount. The loss works its way through the income statement but ends up as a decrease in retained earnings.
