Connecticut's Shrinkflation Disclosure Law (HB 6856): What Small Food Businesses Need to Know
Connecticut's HB 6856 would be the first US state law to regulate shrinkflation, requiring food manufacturers to post a clear notice for 12 months whenever they shrink a product without cutting its price — enforced as an unfair trade practice by the state Attorney General.

Snow Cone and Shaved Ice Truck Bookkeeping: Pricing and Cash Flow for a Four-Month Season
A snow cone costs $0.15–$1.25 to make and sells for $2–$5, but that 200–300% margin only covers costs if fixed expenses like truck payments and insurance are spread across a realistic 12–16 week selling season instead of a full year.
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

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.
