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

Grain Elevator Bookkeeping: Storage Fees, Basis Trades, and Deferred-Price Contracts Explained

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.
Leather Goods Maker Bookkeeping: Why Your Real Material Cost Isn't What You Paid Per Hide
A 50-square-foot hide costing $450 landed with a 64% yield rate has a real material cost of $14.06 per usable square foot, not the $9.00 the invoice implies — the gap driving margin surprises as 2026 tariffs and a shrinking U.S. cattle herd push leather prices up roughly 22%.
Reupholstery Shop Bookkeeping: Bench-Time Costing and the Overhead Trap
A wingback chair takes 7-8 yards of fabric and a sofa 15-22, but shops that price by materials plus a flat labor guess routinely underbill by 20-30% because the fully burdened labor rate and per-job overhead never get calculated — only the fabric receipt does.
The Machine Shop Bookkeeping Guide: Job Costing, WIP, and Real Margins
Machine shops that track only labor and materials miss the two costs that decide whether a job is profitable — machine overhead and work in process — so aggregate revenue looks healthy while a third of jobs quietly lose money.
Shoe Repair & Cobbler Shop Bookkeeping: Job Costing, Materials, and Tax Guide
U.S. shoe repair revenue is roughly $315.6 million and shrinking about 2% a year since 2020, yet job costing, split inventory tracking, and correct sales-tax treatment of repair labor are what let surviving cobbler shops price resoles profitably and diversify into leather goods and wholesale work.
Independent Bookstore Bookkeeping: How to Protect a 2-10% Net Margin
Independent bookstores net just 2-10% per the ABA's ABACUS survey, even with 40-50% gross margins. A practical bookkeeping guide to the transaction types that erode that margin — sale-or-return vendor credits, expiring co-op advertising funds, consignment and trade-credit liabilities — plus the 4-6x inventory turnover benchmark that predicts trouble early.
