With the fiddle-faddle method of accounting, you individually calculate each number shown in the financial statement. For example, the sales revenue figure shown in Table 2-1 equals $13,000. The fiddle-faddle method of accounting requires you to somehow come up with this sales revenue number manually. You may be able to come up with this number by remembering each of the sales that you made during the day. Or, if you prepare invoices or sales receipts, you may be able to come up with this number by adding all the individual sales. If you have a cash register, you may also be able to come up with this number by looking at the cash register tape.

      Other revenue and expense numbers get calculated in the same crude manner. For example, the $1,000 of rent expense gets calculated by either remembering what amount you paid for rent or by looking in your checkbook register and finding the check that you wrote for rent.

      The balance sheet values get produced in roughly the same way. You can deduce the cash balance of $1,000, for example, by looking at the checkbook or, in a worst-case scenario, the bank statement. You can deduce the inventory balance of $3,000 by adding the individual inventory item values. You can calculate the liability and owner’s equity amounts in similar fashion.

      Some of the values shown in an income statement or on a balance sheet get plugged – meaning that they’re calculated using other numbers from the financial statement. For example, you don’t look up the profit amount in any particular place; instead, you calculate profit by subtracting expenses from revenue. You can also, of course, calculate balance sheet values such as total assets, owner’s equity, and total liabilities.

      Okay, I admit it: The fiddle-faddle method of accounting works reasonably well for a very small business as long as you have a good checkbook. So for a very small business, you may be able to get away with this crude, piecemeal approach to accounting.

      Unfortunately, the fiddle-faddle method suffers three horrible weaknesses for a firm that doesn’t have super-simple finances:

      ✔ It’s not systematic enough to be automated. Now, admittedly, you may not care that the fiddle-faddle approach isn’t systematic enough for automation. But this point is an important one: A systematic approach like double-entry bookkeeping can be automated, as you can do with QuickBooks. This automation means that the task of preparing financial statements requires – oh, I don’t know – maybe five mouse clicks. Because the fiddle-faddle approach can’t be automated, every time you want to produce financial statements, you or some poor co-worker goes to an enormous amount of work to collect the numbers and all the raw data necessary to produce information like that shown in Table 2-1 and Table 2-2. In reality, of course, with more complicated financial statements, someone does much, much more work.

      ✔ It’s very easy to lose details. This sounds abstract, but let me give you a good, concrete example. If you look at Table 2-1, you see that the hot dog stand business incurs only three operating expenses: rent, wages, and supplies. If you know the operating expense categories that the business incurs, it’s fairly easy to look through the check register and find the check or checks that pay rent, for example. You can use a similar approach with the wages and supplies expenses. However, what if you also have an advertising expense category, a business license expense, or some other easy-to-forget category? If you forget a category, you miss expenses. For example, if you forget that you spent money advertising and, thereby, forget to tally your advertising expenses, that whole category of operating expense gets omitted from your income statement.

      ✔ It doesn’t allow rigorous error checking. This business about error checking seems, perhaps, nitpicky. However, error checking is important with accounting and bookkeeping systems. With all the numbers and transactions floating around, errors easily creep into the system. I discuss error checking more later in this chapter, but let me give you an example of the sort of error checking an accounting system can (and should) perform. Take a look at the example of the sales transaction. If you sell an item for $1,000, you can actually check that amount by comparing it to your record of what the customer paid. This makes sense, right? If you sell me an item for $1,000, you actually should be able to compare that $1,000 sale to the amount of cash that I pay you. A $1,000 sale to me should correspond to a $1,000 cash payment from me. The fiddle-faddle method can’t make these comparisons. However, double-entry bookkeeping can.

      You see where I’m at now, right? I’ve admitted that you can construct financial statements by using the fiddle-faddle method. But I hope I’ve also convinced you that the fiddle-faddle method suffers some really debilitating weaknesses. I’m talking about something as important as how you can best manage the financial affairs of your business. These weaknesses indicate that you need a better tool. Specifically, you need double-entry bookkeeping, which I discuss next.

       How Double-Entry Bookkeeping Works

      After you conclude that the fiddle-faddle method is for the birds, you’re ready to absorb the necessary accounting theory and learn the bookkeeping tricks required to employ double-entry bookkeeping. Essentially, you need two things in order to work with double-entry bookkeeping. First, you need an understanding of the accounting model, and second, you need a grasp of the mechanics of debits and credits. Neither of these things is difficult. If you flip ahead a few pages, you can see that I’m going to spend only a few pages talking about this material. How difficult can anything be that can be described in just a few pages? Not very, right?

       The accounting model

      Here’s the first thing to understand and internalize in order to use double-entry bookkeeping: Modern accounting uses an accounting model that says assets equal liabilities plus owner’s equity.
