Key Distinctions

Accrual accounting methodvsCash accounting method

Accrual recognizes economic events by matching revenues to expenses at the time the transaction occurs and is GAAP compliant, while the cash method recognizes them only when payment is made or received and does not meet GAAP (in the XYZ example accrual showed $4,000 profit at May 31 and cash showed $0).

Idaho Contractor's Business & Law Reference Manual, Section 5: Accounting & Finance
Leasing equipmentvsRenting equipment

Leasing is a long-term agreement with a locked-in rate, less cash up front, and potential tax benefits, while renting is short-term (by the hour, half day, or whole day) with the owner choosing when to return it and no fee for returning early.

Contractor's Business and Law Reference Manual, Section 5: Accounting & Finance
Current ratiovsQuick ratio (acid-test ratio)

The current ratio divides current assets by current liabilities, while the quick ratio excludes inventories from current assets, giving a more conservative liquidity measure because inventories may not be quickly convertible to cash.

Idaho Contractor's Business & Law Reference Manual, Section 5: Accounting & Finance — Liquidity Ratios
Lump sum contractvsUnit price contract

A lump sum contract covers the entire project as one total, while a unit price contract breaks the project into sections each billed separately with its own cost; both set a final price regardless of the contractor's actual costs.

Idaho Contractor's Business & Law Reference Manual, Section 9: Contracts — Lump Sum and Unit Price (Fixed Price) (Page 86)
Named-peril builder's risk insurancevsAll-risk builder's risk insurance

Named-peril protects the contractor only against losses from items specifically named in the policy, while all-risk is the most common type and provides broader coverage.

Idaho Contractor's Business & Law Reference Manual, Section 7: Insurance – Builders Risk bullet, Page 65
Commercial general liability insurancevsCompleted operations (errors and omissions) insurance

Commercial general liability covers claims arising during construction, while completed operations covers third-party injuries or property damage occurring after the contractor has finished the work.

Idaho Contractor's Business & Law Reference Manual, Section 7: Insurance — Completed Operations
General partnervsLimited partner

A general partner controls the business and is personally liable for partnership debts, while a limited partner contributes capital and shares profits but cannot manage the business and is liable only for the amount contributed.

Division of Occupational & Professional Licenses Contractor's Business and Law Reference Manual (Idaho), Pages 16-17
ADA undue hardship standardvsTitle VII religious accommodation undue hardship standard

Under the ADA, undue hardship means significant difficulty or expense judged against the employer's size, financial resources, and business needs — a higher threshold than Title VII's 'more than a minimal burden' standard.

Idaho Contractor's Business & Law Reference Manual, Section 6 — Americans with Disabilities Act (ADA), Disability Discrimination & Reasonable Accommodation & Undue Hardship
ADA employee-count thresholdvsADEA employee-count threshold

The ADA generally applies to employers with 15 or more workers, while the ADEA applies to employers with 20 or more employees.

Idaho Contractor's Business & Law Reference Manual, Section 6 — Americans with Disabilities Act (ADA)
Employer control over manner, method, and mode of workvsMethod of payment (commission, profit share, fee, per job, or piecework)

For Idaho UI tax exemption, employer control over the manner, method, or mode of doing the work indicates the worker is NOT an independent contractor, while the method of payment is explicitly not controlling.

Idaho Contractor's Business & Law Reference Manual, Section 7: Insurance — Independent Contractor
Common parts of every construction contractvsOptional contract elements

Some items are listed as common parts all construction contracts should include, while specifications (a detailed description of blueprints/plans including material types and quantities) are listed as an optional element (item 5).

Idaho Contractor's Business & Law Reference Manual, Page 86-87
Balance sheetvsCash flow statement

The balance sheet shows liquidity status and ability to meet short-term debt (Assets = Liabilities + Equity), while the cash flow statement summarizes actual or anticipated cash incomings and outgoings and can be the most valuable report for a contractor because of the importance of cash control.

Formulas to Know

Balance sheet / accounting equation (and solving for equity)Assets = Liabilities + Equity; Equity = Assets − Liabilities (e.g., $37,800 − $30,000 = $7,800)
Current ratioCurrent assets ÷ Current liabilities (e.g., $123,450 ÷ $23,450 = 5.26); the higher the ratio, the better
Quick ratio (acid-test ratio)(Current assets − Inventories) ÷ Current liabilities
Straight-line depreciation (annual)(Purchase Price − Salvage Value) ÷ Years of Useful Life (e.g., ($50,000 − $5,000) ÷ 9 = $5,000/yr)
Percentage of completion cumulative revenueCumulative revenue = (Cost incurred to date ÷ Total estimated cost) × Contract price (e.g., ($200,000 ÷ $400,000) × $600,000 = $300,000)
Cash flowCash receipts − Cash payments over a given period; equivalently Net profit + depreciation, depletion, and amortization charged off
Ending cash and cash equivalents (cash flow statement)Beginning cash balance + Net increase in cash (e.g., $1,000 + $10,500 = $11,500)
Net income (income statement)Total Revenue − Total Operating Expenses (e.g., $6,000 − ($1,500 wages + $1,000 COGS + $250 utilities + $250 supplies) = $3,000)
General overhead percentageTotal general overhead ÷ Project's forecasted income (e.g., $75,000 ÷ $750,000 = 10%)
Equipment charge to a projectInternal rental rate × Hours used (e.g., $65.00 × 8 = $520, charged to the project and credited to the equipment's ledger account)
Idaho UI tax late-payment penalty4% of tax due, or $20, whichever is greater, per month or fraction of a month delinquent (e.g., $800 × 4% = $32 × 2 months = $64; $501 × 4% × 2 = $40.08)
