Relation Between Business Events and Financial Transactions

Effectively, what financial reporting standards do is prescribe standard "buckets" into which information about business events needs to go.  There are relationships between some of the "buckets" and the "buckets" need to be organized in certain specific ways.

You don't really need "accounts" to create a financial statement.  But you do need to understand which standard financial report line item needs to contain the information about the business event. But accounting systems tend to not track this business event information.  As such, the information has to be added manually. That is why accounting systems cannot output proper cash flow statements and statements of changes in equity. The business event information does not exist in the accounting system.

Traditionally, in the world of accounting, these "buckets" are formally known as "accounts".  Companies create these accounts, they organize the accounts into what is referred to as a "chart of accounts".  The accounts are not prescribed or otherwise dictated by financial reporting frameworks like IFRS (International Financial Reporting Standards) or US GAAP (United States Generally Accepted Accounting Principles).  What is prescribed is the standard report line items into which business event information flows.

The system is built on a rigid mathematical architecture referred to as double entry bookkeeping that is designed to ensure that every business event which is required to flow through those standard financial statement line items as financial transactions is captured in a way that remains balanced and transparent.

There are five primary types of "buckets" or you might say "master buckets".  These master buckets subdivide information into specific interrelated and intentionally intertwined standard financial statement line items.  This process or technique is referred to as "articulation". Here is a list of those master buckets and a brief description of each in very, very simple terms:

  • Assets: resources owned by an economic entity.
  • Liabilities: obligations that an economic entity has to third parties.
  • Equity: obligations that an economic entity has to the owners of that economic entity
  • Revenues: inflows of resources from business events
  • Expenses: outflows of resources from business events

The above list is, again, expressed in very simple terms to keep this explanation tight. To see a significantly more detailed breakdown, please see my MINI 2026 Financial Reporting Framework and the reference financial reports I have provided using XBRL.

The double entry bookkeeping model is anchored by one unbreakable rule that ensures the accounting records always stay in balance: the accounting equation.  The accounting equation is effectively a universally understood industry norm which states:  Assets = Liabilities + Equity.

So, why do we need standard buckets? The reason these standard buckets are so strictly defined is to achieve cross reporting economic entity comparability.

If different reporting economic entities used different buckets, then it would be impossible to compare reported information across different reporting economic entities.

Financial reporting standards (like IFRS and US GAAP mentioned above) provide what amounts to a "taxonomy" that defines and organizes or classifies the set of buckets the financial reporting standards.  This provides a financial reporting framework.

Think of it as a closed-loop plumbing system. If you pour "value" into one bucket as a result of some business event, it must either come out of another bucket or increase the overall size of the system (Equity) according to very specific, legally-mandated set of rules.

A financial statement is somewhat similar to a Sudoku puzzle. If you look at a financial statement through the lens of a Sudoku puzzle, the logic holds up surprisingly well. Both are closed-loop systems where every entry is governed by a strict set of rules, and a single mistake in one "box" causes the entire grid to fail.

Here is why that comparison is so spot-on: In Sudoku, a "5" in one square dictates what can happen in every other square in that row and block. Financial statements work the same way through double entry bookkeeping. If you change, say, a number on the income statement that forces the balance sheet out of equilibrium because the balance sheet and income statement are tied together mathematically per the accounting equation.

In Sudoku, you know you’ve succeeded when the final numbers fit the 1–9 pattern perfectly. In accounting, the "check figure" or "parity check" is the balance sheet. If  your assets do not equal your liabilities plus equity, the financial statement "puzzle" is broken. Much like Sudoku, you can’t just force a number to fit; you have to go back through the "grid" (the general ledger) to find exactly where the logic deviated.

Financial statements have fixed constraints.  Just as Sudoku has 9x9 squares, financial reporting has standard "line items" (the buckets). You aren't allowed to invent new math; you are simply solving for the correct placement of values within a pre-defined standard structure.

Solving a hard Sudoku often requires tracing back your steps to see where a number was misplaced. Accountants call this an "audit trail". Because every "bucket" has a specific relationship with other buckets, an auditor can look at one corner of the puzzle and determine if the rest of the numbers are mathematically possible.

But there is a big difference between a financial statement and a Sudoku puzzle.  In Sudoku, the numbers are just symbols. In a financial statement, those numbers represent the information provided by all the business events which impacted the economic entity that created the financial statement.  The balance sheet is the "stocks" or "state" of the economic entity and the income statement,  cash flow statement, and statement of changes in equity represent the "flows" or "changes in state" of the reporting economic entity. But as a logical exercise, a Sudoku puzzle and a financial statement are almost identical: total internal consistency.
