How Accounts Become Statements: From the Chart to the Reports You Read

Financial statement

A financial statement is a report built entirely from account balances: the income statement from revenue and expense accounts, the balance sheet from asset, liability, and equity accounts, and the statement of cash flows from the change in those balance sheet accounts over the period. No line on any of these reports comes from anywhere other than the chart of accounts, which is why the chart decides in advance what the reports are able to show.

Most owners meet their books from the reporting end. The income statement arrives, a number looks wrong, and the question is where it came from. The answer is always the same: it came from an account, or from a sum of accounts. This page walks that path in the other direction, from the account to the line, so that the next time a report cannot answer a question you know which account is missing.

Structure

Each account in the chart carries a type, and the type decides which statement the account feeds. Under GAAP (Generally Accepted Accounting Principles) the four statements are prepared in a fixed order: income statement first, then the statement of owner's equity, then the balance sheet, then the statement of cash flows. The order matters because each one hands a number to the next. Net income from the income statement moves into equity; the ending equity balance appears on the balance sheet; the balance sheet accounts feed the cash flow statement.

Below is a generic chart of eight accounts. The Purpose column names the statement line each account produces. Read it as a routing table: the account number and type on the left decide the report and the line on the right.

Two things follow from the table. First, an account can appear on only one primary statement. Rent will never show on the balance sheet, and Equipment will never show on the income statement. Second, the level of detail on the report is capped by the level of detail in the chart. If the chart has one Rent account, the income statement has one Rent line. If the chart splits it into Rent - Office and Rent - Warehouse, the report can show both, and it can also show the total, because the report can add but it cannot divide. For how that split is built, see parent and sub-accounts.

Recording

A statement is the sum of many entries, so the way to understand a statement line is to follow one entry to it. Take two ordinary transactions for a service business. Figures are illustrative.

First, the business invoices a customer for 4,800 of work completed this month. The customer has not paid yet.

Second, the business receives the rent bill for the month, 2,200, and records it before paying it.

Between entries and statements sits one intermediate step: the trial balance, which lists every account with its ending balance. The income statement takes the revenue and expense rows from that list. The balance sheet takes the asset, liability, and equity rows. At the end of the fiscal year the revenue and expense accounts are closed, meaning their balances are moved into equity and reset to zero, so the next year's income statement starts clean. Balance sheet accounts are never closed; the checking balance at 11:59 on December 31 is the checking balance at 12:01 on January 1. That is the mechanical reason the income statement covers a period and the balance sheet describes a moment. For the accrual timing behind entry 2, see accrual vs. cash basis.

Reporting

Here is where the two entries land. Each statement below is an excerpt, and the highlighted rows exist only because the chart has the accounts that produce them.

Gross profit and net income are not accounts. The report calculates them from the accounts above. That is why a business with no cost of sales accounts gets an income statement with no gross profit line: there is nothing to subtract. The distinction between cost of sales and operating expense is covered in cost of goods sold vs. operating expense.

The 4,800 receivable from entry 1 and the 2,200 payable from entry 2 sit here, not on the income statement. The 700 of net income appears under equity because that is where it will be closed at year end. Total assets equal total liabilities and equity, which is the accounting equation, and the report will always balance when every entry has equal debits and credits.

The statement of cash flows has no accounts of its own. It starts from net income and adjusts for the change in each balance sheet account: the 4,800 increase in receivables is subtracted because that revenue brought in no cash, the 2,200 increase in payables is added back because that expense cost no cash yet, and the result reconciles to the change in Checking. Cash spent on equipment appears in a separate investing section, and loans and owner contributions appear under financing. Every one of those sections depends on the balance sheet accounts being separate: if a loan and an equipment purchase both ran through one account, the cash flow statement could not tell financing from investing.

Management reports use the same accounts a second way. A departmental profit and loss report, or a margin report by product line, is an income statement filtered by a dimension the chart provides: either separate accounts per line of business, or a single set of accounts plus a class or location tag in QuickBooks. The excerpt below uses separate cost accounts per service line, which is the arrangement that survives an export to a spreadsheet or a switch of accounting software.

The company-wide gross profit of 2,900 is the same number as on the income statement above. The difference is that this report can show that Design earns a 71 percent margin and Installation earns 45 percent. A chart with one revenue account and one cost account can produce the 2,900 and nothing else.

Insight

The reports you read at month end were decided months earlier, when the chart was set up. Here are three questions a business asks all the time that a report cannot answer unless the chart already separates the accounts.
