Inventory tracking, valuation, and management for businesses
Christmas light installation businesses collect nearly all their annual revenue in a six-to-eight-week window each fall, so booking October deposits as deferred revenue and sizing a reserve to a ten-month off-season — not the generic three-month rule — determines whether the business survives to next November.
Small importers lose margin points when tariffs hide in inventory costs. Here are 5 accounting strategies to recalculate landed cost, plan inventory properly, separate tariff line items, capitalize duties correctly, and claim refunds—so you can see tariff impact in real time.
The diameter × height × multiplier formula that most bowl turners use to price work ignores cracked blanks, drying time, and overhead — accounting them correctly as a separate spoilage loss (not folded into COGS) reveals whether a shop's pricing actually covers its real costs.
Amazon's July 30, 2026 New Selection Program update caps referral fees at 10% on the first 100 units and 5% on the next 100 for new-to-FBA parent ASINs, waives storage and liquidation fees on the first 200 units for 120 days, and adds $125 in Vine and coupon credits — but existing enrollees must reconfirm by October 31, 2026 to keep qualifying new listings.
Bait and tackle shops run three revenue models through one register — perishable live bait, hard goods, and state fishing-license sales. Live bait mortality should be booked as shrinkage expense (tracked by species and supplier), bait-dealer licenses are recurring compliance costs tiered by sales volume in states like Wisconsin, and license sales are commission revenue (typically 4.75%–5%) with the state's share held as a liability, never income.
The cash conversion cycle (CCC = DIO + DSO − DPO) measures how many days cash stays trapped in operations. A worked example shows a wholesale firm with a 66-day cycle tying up roughly $110,000 in working capital, and lays out tactics to shorten collections, inventory, and payables.
Return on Net Assets (RONA = Net Income ÷ Fixed Assets + Net Working Capital) measures whether the equipment, vehicles, and inventory a business owns are actually generating profit. Includes a worked example, rough benchmarks (above 5% acceptable, above 20% outstanding), and how RONA differs from ROA and ROE for capital-intensive small businesses.
U.S. retailers lost $90–112 billion to inventory shrinkage in the latest reporting cycle, an average shrink rate near 1.6% of sales. This guide shows small retailers how to book shrink in a dedicated expense account instead of burying it in COGS — with the exact journal entries, cycle-counting schedules, materiality thresholds, and the process fixes behind the ~70% of shrink that isn't theft.
Amazon ends stickerless commingled inventory on March 31, 2026. Resellers must apply FNSKU labels ($0.20–$0.50/unit) while Brand Registry owners get virtual tracking; unlabeled stock gets flagged defective. Here's the labeling deadline timeline, who pays what, and the lot-level costing and landed-cost accounting changes sellers need before the cutoff.
A practical bookkeeping guide for med spa owners covering the industry's hardest problems — tracking expiring injectable inventory with FIFO and treatment recipes, calculating 15–25% injector commissions from provider-level revenue, deferring membership and package revenue until services are delivered, and building a chart of accounts that shows which service lines actually carry margin.
A reloading supply shop that only sells bullets, brass, primers, and powder owes no federal ammunition excise tax — but loading and selling finished ammunition triggers an 11% FAET liability filed quarterly on TTB Form 5300.26. This guide covers the chart of accounts, lot-number FIFO inventory tracking, and hazmat freight costing that keep a component retailer or hybrid manufacturer compliant.
Average-cost and FIFO inventory methods misstate margins when every item is unique. How antiquarian booksellers use specific-identification inventory — per-copy cost basis, proportional lot allocation, condition-driven write-downs, and provenance records — to keep accurate books on one-of-a-kind stock.
