Modern bookkeeping techniques using plain-text and automated workflows
Forty-five states require scrap yards to keep seller-ID records, cash caps run as low as $30 (Washington), and IRS Form 8300 is due within 15 days on cash over $10,000. A practical guide to building a purchase ledger that survives police, state regulator, and IRS scrutiny.
Substack newsletter creators are self-employed under IRS rules, owe 15.3% self-employment tax on net profit via Schedule C, and receive a 1099-K only above $20,000 in gross payments and 200 transactions — though all income must be reported regardless.
Toast charges roughly 2.99% + 15¢ per transaction, Clover about 2.3% + 10¢, and Square 2.4–2.6% + 15¢ — a side-by-side breakdown of POS pricing, hardware costs, and contract terms to help restaurant and retail owners pick the right system in 2026.
Board game cafes blend three businesses — admission fees, food and beverage, and retail — and each needs its own revenue and COGS account; the game library itself should be capitalized and depreciated over 3-5 years, not expensed, while shrink-wrapped retail copies stay inventory.
Consolidated statements group a parent with the subsidiaries it controls under ASC 810; combined statements group entities that share a common owner with no parent-subsidiary link — the structure most multi-LLC owners actually have. Both require eliminating intercompany transactions, and neither changes how each LLC files taxes.
Under 19 CFR 111.29, customs brokers must book client duty payments as liabilities, remit funds to CBP within five working days, and furnish a written accounting statement within 60 calendar days — a discipline that also protects duty drawback claims, which can recover up to 99% of duties paid on later-exported goods.
Disc golf courses run four businesses in one — real estate, retail, memberships, and events — and each needs separate accounting for deferred membership revenue, 15-year land improvement depreciation, and pro shop cost of goods sold.
A $650 prepaid lesson package is a liability, not revenue, until the lessons are delivered. How driving schools handle deferred revenue, choose between Section 179 (up to $12,200 for light vehicles, $32,000 for 6,001–14,000 lb GVWR in 2026) and standard mileage on dual-control cars, classify instructors as 1099 or W-2 under the IRS three-factor test, budget for state surety bonds ($2,000–$50,000), and track the two KPIs — revenue per vehicle-hour ($70+ target) and instructor utilization (75–85%) — that predict margins.
Rental e-bikes and scooters are fixed assets, not inventory — and useful life ranges from under two months for early shared scooters to 2–3+ years for reinforced fleet hardware. How micromobility operators should structure a chart of accounts that separates batteries, theft, and field-ops labor, calculate contribution per vehicle per day, book damage deposits as liabilities, and find breakeven on blended seasonal utilization rather than peak-week numbers.
A chart-of-accounts and depreciation framework for e-bike and scooter rental fleets, showing how to track vehicles by acquisition cohort, calculate gross margin per ride, and model a realistic path to breakeven by year three.
Demand charges can account for 30–70% of a commercial electricity bill and add roughly $9,000 to a single month when six DC fast chargers peak simultaneously — yet most operators blend them into one utilities account. How to book charging revenue against per-kWh COGS, track the Section 30C credit that now sunsets June 30, 2026, and model realistic payback periods for Level 2 ($4,500–$12,000/port) and DC fast chargers ($90,000–$200,000/port).
Flight schools should book prepaid block-time packages as deferred revenue, distinguish owned aircraft from leaseback and dry/wet-leased aircraft for depreciation purposes, classify CFIs correctly against IRS behavioral-control tests, and track revenue-per-aircraft-hour to know if the business is actually profitable.
