How to Use This Skill
- Without arguments - use the core accounting workflow and decision rules below.
- With a topic - find the topic in the index, then read the linked chapter file.
- With a chapter - ask for
ch05, ch12, or Appendix B to load the relevant reference.
- For a procedure - use
patterns.md for the compact method and the chapter for a worked example.
- For a formula or definition - check
cheatsheet.md and glossary.md, then verify context in the chapter.
This skill captures the textbook's accounting framework and examples. It is not a substitute for current GAAP/IFRS, tax, legal, audit, or professional advice; standards and jurisdiction-specific rules can change.
Core Frameworks & Mental Models
1. Treat accounting as a decision-information system
Use the sequence identify, record, communicate. Start with the user's decision and the relevant evidence, not with a memorized account title. Classify what the business owns, owes, earns, consumes, invests, or finances. Then communicate through linked statements and analysis.
The expanded accounting equation is the first diagnostic:
Assets = Liabilities + Common Stock - Dividends + Revenues - Expenses
Keep it in balance after every transaction. Revenue is recognized when earned, expense when incurred or matched to revenue, and dividends as distributions to owners rather than expenses. Cash timing is evidence of liquidity, not a complete measure of performance.
2. Use the accounting-cycle trace
Follow the evidence chain: source document -> transaction analysis -> journal -> ledger -> trial balance -> adjusting entries -> adjusted trial balance -> statements -> closing entries -> post-closing trial balance. A balanced trial balance proves arithmetic equality, not that the right account, amount, or transaction was used.
At period-end, use the current-to-should bridge: determine what an account currently represents, calculate what it should represent, and record the difference. Prepaids, unearned revenues, accrued expenses, and accrued revenues each connect one income-statement account to one balance-sheet account. Adjustments do not use Cash. Close revenues, expenses, Income Summary, and Dividends; carry assets, liabilities, Common Stock, and Retained Earnings forward.
3. Separate merchandising flow from service flow
For a merchandiser, reason through:
Net sales - COGS = Gross profit
Under perpetual inventory, every sale needs two sides: the revenue/receivable side and the COGS/inventory side. Establish ownership before cost arithmetic: FOB shipping point transfers ownership at shipment; FOB destination transfers it on arrival. Reconcile beginning inventory + net purchases = COGS + ending inventory and use the physical count to identify shrinkage.
Select inventory methods for the reporting question. In rising-cost periods, FIFO generally raises ending inventory and income, LIFO raises COGS and lowers income, and weighted average smooths changes. Specific identification is for traceable units. Use lower of cost or market as a downward valuation test and interpret turnover with stockout risk.
4. Control cash and estimate credit losses
Design internal control around responsibility, documentation, insurance/bonding, separation of custody from records, separation of related duties, technology, and independent review. Use the Fraud Triangle - opportunity, pressure, rationalization - to identify risk, but remember collusion, override, error, and cost-benefit limits.
For bank reconciliations, keep timing items on the bank side with no entry and journalize only book-side items such as fees, collections, interest, NSF checks, and errors. For receivables, distinguish a current-period loss estimate from a later write-off. Use the allowance method for material balances; percent of sales targets expense, while percent of receivables and aging target the ending allowance.
5. Match long-lived assets and obligations to time
Capitalize normal, reasonable, necessary readiness costs; allocate depreciable cost using a method that fits consumption; revise estimates prospectively; and update depreciation before disposal. For debt, use the contract rate for cash interest and the market rate for bond price and effective-interest expense. A discount or premium amortizes the carrying value toward par.
Classify liabilities by the longer of one year or the operating cycle. For contingencies, ask whether a past event created a present obligation, then apply probability and estimateability: record when probable and estimable, disclose when reasonably possible or probable but not estimable, and otherwise take no action.
6. Read equity and cash flows as ownership and purpose
Keep paid-in capital, retained earnings, preferred rights, dividends, and treasury stock distinct. A stock dividend changes the allocation within equity; a stock split changes share descriptions without changing total equity. Under the cash-flow statement, classify by purpose: operating runs the business, investing changes productive assets/investments, and financing changes debt principal or owners' equity. Indirect operating cash reverses noncash accrual effects and working-capital timing; noncash investing/financing is disclosed rather than invented as cash.
7. Analyze before judging
Choose among liquidity/efficiency, solvency, profitability, and market-prospect blocks based on the decision maker's question. Combine horizontal dollar/percentage changes, vertical common-size analysis, and ratios. Compare across time, competitors, industry data, and cautious benchmarks. Ratios are signals: inspect their numerator, denominator, accounting policy, business model, and underlying explanation. Separate sustainable continuing operations from unusual items, discontinued operations, and accounting changes.
