Olive Oil Mill Bookkeeping: Custom Crush Fees, Yield-Driven COGS, and the Harvest Cash Cliff
How to keep books for an olive oil mill that earns most of its revenue in a six-to-ten-week harvest window — separating custom-crush milling fees from own-label inventory accounting, tracking extraction yields that swing from 50 to 200 pounds of olives per gallon, valuing bulk oil in tank storage, and handling Schedule F, cash-method, and UNICAP tax questions.
Tire Retreading Bookkeeping: Why the Casing on Your Shelf Is Worth More Than the Rubber You Just Cured
How tire retreaders should book casing custody, core credits, and warranty adjustments — customer-owned casings stay off your inventory, core credits are an inventory purchase rather than an expense, and prorated warranty claims justify a monthly accrued reserve. Includes example beancount entries and a minimal chart of accounts.
Sneaker Resale Bookkeeping: Cost Basis, Cop-and-Flip Inventory Tracking, and Why StockX/GOAT 1099-Ks Rarely Match Your Actual Profit
A 1099-K from StockX or GOAT reports gross payments, not profit. Here's how sneaker resellers track per-pair cost basis, apply FIFO to cop-and-flip inventory, deduct platform fees that run 10-12% per sale, and meet the restored $20,000/200-transaction reporting threshold with clean books.
Teeth-Whitening Studio Bookkeeping: Why an 85% Gross Margin Can Still Hide a Losing Business
Teeth-whitening studios often run an 85%+ gross margin on sessions but fail because they recognize prepaid package revenue too early, skip inventory shelf-life write-offs, and miscategorize licensing costs tied to their state's cosmetic-vs-dental classification.
Used Cooking Oil Collection: A Bookkeeping Guide for a Commodity Business on Wheels
A single 50-gallon barrel of used cooking oil is worth $100-185 to a biodiesel refiner, so collectors must book collected-but-unsold oil as inventory-in-transit, track actual weighed pounds per stop rather than estimates, and reconcile collected-to-shipped volume weekly to catch theft and double-invoicing before it erodes route profitability.
Wine Bar and Wine Shop Bookkeeping: FIFO Inventory, By-the-Glass Costing, and the On-Premise/Off-Premise Split
A 750ml bottle yields about 5 five-ounce pours, and wine pour cost typically runs 25–30% versus 18–24% for liquor. This guide covers FIFO costing by vintage, by-the-glass yield math, shrinkage as a real COGS line, and why wine bars need separate on-premise and off-premise revenue and COGS accounts from day one.
Eyelash Extension Studio Bookkeeping: The Supply, Retail, and Depreciation Lines Most Lash Artists Get Wrong
A lash studio's costs don't fit one "supplies" line — service consumables, retail inventory, and depreciable equipment like lash beds and LED lamps each need their own account. This guide covers a six-category chart of accounts, the Section 179 deduction most lash artists miss, quarterly retail inventory counts, and booth-renter vs. employee classification.
Sneaker and Trading Card Reselling Taxes: The 2026 Bookkeeping Guide
The 2026 IRS 1099-K threshold for platforms like eBay, StockX, and Whatnot is back to $20,000 and 200 transactions, but sneaker and trading card resellers still owe tax on profit below that line — here's how to nail cost basis, inventory tracking, and the hobby-vs-business test.
Custom Guitar Luthier Shop Bookkeeping: Why Your Wood Rack Isn't Inventory and Your Deposits Aren't Revenue
Custom guitar luthiers should book customer deposits as a liability (deferred revenue) until delivery, track each tonewood set's acquisition cost and CITES paperwork individually rather than by replacement value, and use job-based WIP tracking to compare actual labor hours against a typical 40-80 hour build estimate.
GMROI Explained: The Gross Margin Return on Inventory Investment Formula and 2026 Benchmarks
GMROI measures gross profit generated per dollar of average inventory cost; a GMROI above 3.0 is generally strong, below 1.0 means inventory is destroying margin dollars, and typical category ranges run from 1.2 in grocery to 6.5+ in electronics.
Grain Elevator Bookkeeping: Storage Fees, Basis Trades, and Deferred-Price Contracts Explained
Grain elevator bookkeeping separates elevator-owned inventory from bailment grain held for producers, tracks basis and deferred-price (NPE) contracts as distinct liabilities, and recognizes storage fees as service revenue earned over time rather than as a sale.
Kiteboarding School Bookkeeping: Why IKO's Insurance Structure Puts Liability on Individual Instructors, Not the School
IKO's Basic Instructor Membership covers instructors for recreational liability but excludes students during lessons unless the instructor teaches through a recognized IKO Center, a coverage gap kiteboarding schools should reflect in separate insurance sub-accounts, fleet depreciation schedules, and worker-classification decisions.
