21. Finance is all about Flow

Essentially, double-entry bookkeeping is a process by which business entities track the flow of resources from one place to another. However, because accounting reports were developed when computational tools were limited or nonexistent, they do not report a measurement of this all important flow.

Contrary to myth, the recording of each transaction in two places is not a method of error checking; each of the two data entries of an accounting transaction has a specific meaning that allows businesses to maintain a record of their dynamic activity, rather than mere static positions. The two entries of double-entry bookkeeping, of course, are called “credit” and “debit.” The credit entry represents a withdrawal from the source of the transfer and the debit entry represents a deposit in the transaction’s ultimate destination. By entering both the credit and debit ends of resource transfer, the bookkeeper is actually producing a complete record of a movement of financial resources, a “flow” of resources from one place to another.

The standard GAAP reports are all produced from the balances that remain at the various source and destination accounts. With the exception of the Cash Flow Statement, they do not report the important record of what is originally recorded by the bookkeeper – the actual flow of resources that occurs between various accounts. This is surely a product of the crude and limited computational tools that were available to the originators of the reports. Perhaps with the recent invention of the Cash Flow Statement, however, this limitation is beginning to change.

The Cash Flow Statement represents a leap forward in accounting practices. It reports more than the existing balances within various accounts; it actually attempts to track the flow that changed those balances during a period. The Cash Flow Statement, however, is limited to only those flows that affect the Cash account, but it perhaps points to the potentially much greater amount of information that can be produced with modern automation.

With modern automation and data structures, the Cash Flow Statement, or even a more general flow report, should be the easiest to produce. That fact that it is problematic for most accounting departments is a result of the fact that financial reports are produced from the resulting balances in accounts rather than the potentially trivial process of measuring flow by simply totaling all transactions by the combination of the account that they credit and the account that they debit.

A complete report of the total amount of flow between all of the accounts can be done easily with modern data warehouse architecture and, from these total flows, we can measure the changes of balances that they cause and thereby produce all of the other GAAP reports. Furthermore, we can keep a database of daily flows that would allow us to produce dynamic reports for arbitrary windows of time, rather than the current practice of generating reports for specific periods only.

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.

16. Flow, Measurement, and Analysis

There are three simple ideas that will revolutionize financial information in the twenty-first century. All financial information is derived from the fundamental data that is recorded by double-entry bookkeepers and reported by accountants in various GAAP reports. By going to the original meaning of fundamental double-entry data, more financial information will be produced and financial resources can be more wisely allocated.

1. Financial data has for over five-hundred years been stored in what is now called a data warehouse. The records of financial transactions in a traditional bookkeeping journal are fundamentally the same as a data warehouse, differing only because of the primitive forms of recording that existed before automation. We need to update the journal according to modern data warehouse techniques.
2. Financial data is far more intuitive and easy to understand in its original intent and has become complicated and obscure because that original intent has been lost by modern accountants. The most significant cause of this obscurity is the so-called accounting equation, which was developed with a primitive numbering system, is mathematical nonsense, and serves to make the simple concepts of finance nearly incomprehensible.
3. The primary thing that double-entry bookkeeping is doing is keeping track of the flow or movement of financial resources from one financial space to another. The GAAP reports report balances or changes in balances in those financial spaces rather than the flow. This is primarily due to the lack of automation during the development of traditional accounting. In the 1980’s, the financial world moved toward the tracking of flow with the addition of the Cash Flow Statement. This is an improvement in the right direction, but it is just a start to the real financial analysis that comes from studying the flow of all of the resources.

I have dealt with these ideas in my two books, Banking the Past and The Tao of Financial Information. Banking the Past addressed the first idea while The Tao of Financial Information addressed the last two. In following blog posts, I will summarize the powerful solutions offered in those two works. By returning to the foundation of financial information, we can profoundly increase the intelligence that we use in allocating our resources.

6. The On-Demand Cash Flow Statement

The cash account should always have a debit balance or be equal [zero balance].
Otherwise, the account will be in error.
Luca Paciolo, Particularis de Computis et Scripturis

The Cash Flow Statement is nothing more than a summary of activity in the company’s cash account. It summarizes how the cash account was debited and credited by the company’s operating, investing, and financial activities during a particular period of time. The debits are referred to as “input” in the report while the credits are therein referred to as “output.”

Typically, a Cash Flow Statement, like an Income Statement, summarizes activity for a particular fiscal period. However, unlike the Income Statement, the Cash Flow Statement does not require that the company’s books be closed before its preparation. This means that, although the Cash Flow Statement summarizes a time period, it is not locked into the constraints of a fixed fiscal period such as the Income Statement is. A Cash Flow Statement could, theoretically, be prepared at any time without the closing of the books and the use of temporary accounts that exist only for the company’s fiscal period.

The Cash Flow Statement could be prepared on a weekly, monthly, or even daily basis. The only impediment to this powerful ability to create useful information is the intensive labor that is required to create the Cash Flow Statement and the only solution to this impediment is to store all of the financial transactions in a data warehouse. A Cash Flow Statement for any time period desired can be prepared effortlessly in seconds with a simple command to a well-designed financial data warehouse.

The use of a data warehouse to back up an accounting system (or be the accounting system) is the key to producing real-time financial statements for arbitrary time periods. This fact is most apparent in the case of the Cash Flow Statement and its growing importance within the company. See Banking the Past, p. 169.
