Learn how to calculate and track cost of goods sold for inventory valuation
A camper van conversion shop that installs living-space modules on incomplete chassis is a final-stage manufacturer, not a services business: the chassis is WIP inventory, certification costs are manufacturing overhead, and deposits stay contract liabilities until ASC 606 over-time recognition turns cost-to-cost progress into revenue.
Customer-pay appliance repair calls earn roughly $200 in profit versus about $75 for warranty calls, and parts carry 30-100% markup — books that track parts cost per job, truck stock as real inventory, and the warranty-retail mix reveal which calls actually make money.
Only the Importer of Record can claim a share of the $166 billion in IEEPA tariff refunds through CBP's CAPE portal, which locks out most small importers who buy through suppliers, freight forwarders, or 3PLs — here is how to find your IOR, negotiate refund sharing, and book the proceeds correctly under ASC 450.
Membership revenue isn't earned when the cash arrives—it's earned daily as members climb. Learn how climbing gym owners calculate deferred revenue, classify route-setting labor, and forecast profitability.
Land surveying firms typically run overhead rates of 100-150% of direct labor and need a break-even multiplier of 2.75-3.25x to stay profitable, but most price off gut feel and burdened-labor guesses instead of job-level cost tracking.
A managed service provider chart of accounts should split recurring MRR, hardware resale, and project/T&M into separate revenue and COGS lines, since blended margins of ~42% can hide 58% recurring services next to 8% hardware resale.
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.
A chart-of-accounts guide for document shredding and data destruction companies covering three revenue streams (route, purge, hard drive destruction), NAID AAA certification costs ($3,000-$5,000 first year), chassis-vs-shredder depreciation, and treating paper recycling rebates as revenue rather than an unreconciled deposit.
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.
A pool route can look fully booked and still lose money on a third of its stops. Splitting chemical costs into their own COGS line, tracking loaded labor and per-mile drive costs, and building a seasonal cash reserve are what turn "busy" into a verifiably profitable pool service business.
A bookkeeping guide for small billboard and out-of-home (OOH) operators — why yield and volume must be tracked separately, why ground leases belong in COGS tagged by board, how static and digital faces differ on depreciation and revenue recognition, and the five KPIs worth reviewing, including 85%+ utilization targets and a ~2.5-year payback benchmark on new digital builds.
