19. Inventing Double-Entry Financial Analysis

All of the financial information in the world comes from double-entry data. Regardless if we are quantifying earnings, assets, or liquidity ratios, the underlying data that is the basis of our analysis is made up of the records of double-entry bookkeepers.

Accounting has been called the “language of business.” This business for which accounting provides a language is an activity, an ongoing process of trading goods and services to others. To serve as the language of business, accounting must provide the record of an activity rather than a simple status. The activity that is measured by the financial records of accountants is the flow of financial resources from one place to another. The purchase of a retail item involves the flow of cash from a customer into the company’s assets and the flow of inventory from the company’s stocks to the consumer. The payment of an expense involves the flow of cash, or its equivalent, for a service provided the company. All double-entry data is the record of the activity of financial resources flowing from one place to another.

The “double” in double-entry is the critical tracking of the flow of financial resources. Each transactions involves the record of a withdrawal (“credit”) from one place and a corresponding deposit (“debit”) to another. If bookkeepers are only going to keep the record of certain financial balances, single-entry bookkeeping would be sufficient, but, if they are going to keep track of an activity, they need to maintain a record of the “before” and “after” images of the financial state. This “double” in double-entry provides the record of an activity – the activity known as business.

However, because of a lack of automation, the summaries of these financial flows have been historically limited to the report of static balances and the changes to those balances occurring during certain time periods. The Balance Sheet reports the surplus of deposits over withdrawals in all of the permanent accounts. The Income Statement reports the differences between the balances accrued to the revenue accounts and those accrued to the expense accounts. Each statement reports the amount of accumulation in each account rather than the actual flow that has occurred between the accounts and was faithfully reported by the bookkeeper. While the data recorded is of dynamic flows, the reports that run our economy are of static balances.

With the age of automation and the ability to more finely summarize the double-entry record of flows, we have gained some insight into financial flows. In the 1980’s, the Cash Flow Statement was introduced, showing the sources and destinations of resources flowing into and out of the cash account. However, for no other reason than the clumsy methods of traditionally producing financial reports by hand, the Cash Flow Statement has been difficult for most companies to produce. This difficulty can be simply overcome by the application of appropriate information design techniques. With modern information technology, not only can the Cash Flow Statement be produced with a trivial single database command, but the quantifying of all flow, not just cash, can be reported and analyzed.

The technique of producing a summary of all of the flows in an accounting system will revolutionize financial information in the twenty-first century. A single database query can produce a report showing all of resources that have gone from every account to any other account. This simple process can provide not only a Cash Flow Statement and all the other standard reports, but also the financial profile of the complete activity of the business. Accounting, as it is recorded, is the language of business, but now, with modern automation and wise information design, it can also produce reports that will be the language of business – the true power of double-entry bookkeeping can be unleashed by double-entry reporting.
