- GAAP
GAAP is the common set of accounting standards that businesses in the United States follow when they prepare financial statements for people outside the company. GAAP (Generally Accepted Accounting Principles) is written by the Financial Accounting Standards Board, and a GAAP-shaped chart of accounts is one in which every account is typed and named so that those standards can be applied at the moment a transaction is recorded, not repaired at year end.
Most of GAAP has nothing to do with the chart of accounts. Standards on leases, revenue contracts, and financial instruments sit on top of the chart and rarely change its shape. Four ideas do reach down into the chart itself, and a small business that gets these four right has done most of what a lender or an accountant will ever ask of its books. They are matching, consistency, materiality, and classification. This page walks each one through the structure it needs, the entry it produces, and the statement line it changes.
Structure
The chart below is generic and small. It carries the accounts the four principles need and nothing else. Matching needs a prepaid account and an accrued liability so that cost can be moved into the right period. Classification needs a clear line between cost of sales and operating expense, and between a current and a long-term liability. Consistency and materiality are habits, not accounts, but the chart still has to leave room for them: a line for small items, and no line that invites a different treatment each month.
| Row | Account | Number | Type | Purpose |
|---|---|---|---|---|
| 01 | Cash - Operating | 1000 | Bank | Main operating account |
| 02 | Prepaid Expenses | 1400 | Other Current Assets | Costs paid now for a benefit in later periods |
| 03 | Accounts Payable | 2000 | Accounts Payable | Vendor bills received, not yet paid |
| 04 | Accrued Expenses | 2300 | Other Current Liabilities | Costs incurred this period, bill not yet received |
| 05 | Long-Term Loan | 2700 | Long Term Liabilities | Bank debt due beyond twelve months |
| 06 | Product Sales | 4000 | Income | Revenue from goods delivered |
| 07 | Cost of Goods Sold | 5000 | Cost of Goods Sold | Direct cost of the goods in 4000 |
| 08 | Insurance | 6100 | Expenses | Coverage cost for the period |
| 09 | Professional Fees | 6200 | Expenses | Accounting, legal, and similar services |
| 10 | Small Tools and Supplies | 6900 | Expenses | Items below the capitalization threshold |
Two accounts on this list exist only because of matching: Prepaid Expenses (1400) and Accrued Expenses (2300). A cash-only chart can drop both, and many small businesses do. The cost of dropping them is that every prepaid annual bill lands in one month, and every December service invoiced in January lands in the wrong year.
Recording
The matching principle, which the textbooks also call the expense recognition principle, says that an expense belongs in the period in which it helped earn revenue. When the cost was paid is a different question. Two entries show what that means. Figures are illustrative.
Say the business pays 12,000 on January 2 for a year of liability insurance. The coverage supports sales in all twelve months, so the cost belongs to all twelve months. On the day of payment, nothing has been used yet.
| Account | Debit | Credit |
|---|---|---|
| 1400Prepaid Expenses | 12,000 | |
| 1000Cash - Operating | 12,000 | |
| Totals | 12,000 | 12,000 |
Cash left the business, but no expense has been recognized. The payment bought an asset: twelve months of coverage.
At the end of January, one month of coverage has been used up. One twelfth of the cost moves from the asset to the expense line, and the same entry repeats each month until the asset is gone.
| Account | Debit | Credit |
|---|---|---|
| 6100Insurance | 1,000 | |
| 1400Prepaid Expenses | 1,000 | |
| Totals | 1,000 | 1,000 |
January carries 1,000 of insurance cost, the same as every other month. Without this entry, January would show 12,000 and February through December would show nothing.
The other direction is the accrual. Say the accountant did the January close and will invoice 1,800 for it in February. The work supported January, so the cost belongs in January even though no bill exists yet.
| Account | Debit | Credit |
|---|---|---|
| 6200Professional Fees | 1,800 | |
| 2300Accrued Expenses | 1,800 | |
| Totals | 1,800 | 1,800 |
The expense is in January. When the invoice arrives in February, it clears the liability and touches no expense account.
Consistency has no entry of its own. It is the rule that Entry 2 is made the same way every month, and that the accounting fee is accrued every close, not only in the months someone remembers. A chart supports consistency by giving each recurring cost exactly one account, so that there is no second place the same cost could go.
Reporting
The income statement for January shows what matching produced. The two highlighted lines carry one month of cost each. Under a cash-only treatment, the insurance line would read 12,000 and the professional fees line would read zero, and January would look like the worst month of the year for no reason connected to the business.
| Product Sales | 48,000 |
| Cost of Goods Sold | 19,200 |
| Gross margin | 28,800 |
| Operating expenses | |
| Insurance | 1,000 |
| Professional Fees | 1,800 |
| Small Tools and Supplies | 340 |
| Total operating expenses | 3,140 |
| Net income | 25,660 |
Example figures.
The Cost of Goods Sold line is highlighted for a different reason: classification. Gross margin only means something if the line above it holds the direct cost of the goods sold and nothing else. A chart that lets insurance or professional fees drift into the 5000 range produces a gross margin that cannot be compared with last year's or with any other business. The balance sheet has the same dependency. The current and long-term split below is what a lender reads first, and it exists only because the chart typed the loan correctly.
| Current assets | |
| Cash - Operating | 31,400 |
| Prepaid Expenses | 11,000 |
| Current liabilities | |
| Accounts Payable | 8,600 |
| Accrued Expenses | 1,800 |
| Long-term liabilities | |
| Long-Term Loan | 60,000 |
Example figures.
Materiality is the principle that decides how far to take all of this. It says that an amount matters when leaving it out or getting it wrong would change what a reader decides. A 12,000 insurance premium is material to a business with 48,000 of monthly sales, so it gets spread across the year. A box of printer paper that costs 40 and lasts three months is not, so it goes straight to Small Tools and Supplies (6900) the day it is bought. The same dollar amount can be material to one business and immaterial to another, which is why the threshold is a judgment and not a rule. Write the threshold down once, apply it every time, and the judgment becomes consistent.
Insight
- 01Was December really the best month of the year, or did the annual premiums paid in January make every other month look worse by comparison?
- 02Is gross margin falling because the cost of goods went up, or because an operating cost was coded into the 5000 range this quarter and not last quarter?
- 03Can the bank see how much of the debt is due in the next twelve months, or does one Loans Payable line hide a payment the business cannot make?
The mistake to avoid is treating this as an audit checklist to run once a year. By then the entries are made and the statements are built on whatever accounts existed at the time. The chart is where GAAP is applied first, because it decides what an entry can even say.

Frequently asked questions.
Do all businesses need to follow GAAP?
Public companies must. Most private small businesses are not legally required to, but a lender, an investor, or a buyer will usually ask for statements prepared on that basis, and tax returns start from books that follow the same classification logic. Building the chart on GAAP lines from the start avoids rebuilding it later.
Is GAAP the same as tax accounting?
No. Tax rules decide what is deductible and when; GAAP decides how the business reports its performance. The two overlap in most small businesses, but they differ on items like depreciation methods and some accruals. A chart built on GAAP classification supports both.
Who writes GAAP?
In the United States, the Financial Accounting Standards Board (FASB) writes the standards for businesses. The Securities and Exchange Commission requires public companies to follow them.
