Inventory tracking, valuation, and management for businesses
How comic and TCG shops should book consignment splits, buylist store credit, and graded-card cost basis — consigned goods stay off the balance sheet, store credit is a liability until redeemed, and high-value singles need specific identification, not average costing. Plus where the IRS draws the hobby-vs-dealer line, from the nine-factor §1.183-2(b) test to the 28% collectibles rate.
Inventory distortion costs retailers $1.77 trillion a year in stockouts and overstock, and multichannel sellers on Shopify, Amazon, and POS are especially exposed to sync lag, phantom inventory, and manual reconciliation errors—this guide covers real-time sync, cycle counts, and reorder-point formulas to fix it.

Filament is only 20-30% of what a 3D print actually costs - machine depreciation, a 2-25% failure rate, and labor make up the rest, and Section 179 combined with 100% bonus depreciation under the OBBBA can let a print-for-hire shop deduct a new printer's full cost in the year it's purchased.
