On June 22, 2026, Walmart quietly cut Marketplace referral fees in 14 categories — steepest in apparel, electronics, and home goods — while Amazon's 2026 FBA costs rose. How sellers can verify their new rates in Seller Center, stack New Seller Savings discounts, and track the margin impact in their books.
TikTok Shop's visible 6% referral fee becomes an effective 25-30% take once creator commissions (category medians 8-20%), Fulfilled by TikTok charges ($2.86-$4.28 per unit), and refund admin fees stack up. How US sellers should book gross revenue, each fee category, and marketplace payouts using accrual accounting.
Restaurant labor costs now average over 36% of sales industry-wide, up from the old 30% rule of thumb. A practical guide to tracking labor cost and prime cost weekly — including a 35-hour overtime alert threshold, demand-driven scheduling that cuts labor cost 20–30%, and the chart-of-accounts setup that makes it all measurable.
Operating margin — operating income divided by revenue — shows whether a business's core operation makes money before interest and taxes. Here's the formula with a worked example, 2026 benchmarks by industry (SaaS 15–35%, services 15–25%, manufacturing 8–15%, retail under 5%), how it differs from gross and net margin, and the bookkeeping errors that distort it.
A $350 junk removal job with a 60% gross margin often nets just $50–$100 after acquisition cost, truck payments, and overhead. Here's how per-job costing — tracking labor, fuel, and dump fees against each individual job — closes the gap between gross and net margin for hauling businesses.
The June 2026 NFIB Small Business Optimism Index rose 2.1 points to 97.4 — a four-month high — while 21% of owners named inflation their top problem and 38% raised prices, the most since January 2023. Here's how to turn those numbers into a data-driven pricing decision.
On April 26, 2026, USPS layered a temporary 8% surcharge on Priority Mail, Priority Mail Express, Ground Advantage, and Parcel Select — on top of January's general rate increase — scheduled through January 17, 2027. Why small shippers absorb more of the hit than enterprise accounts, why the sunset date deserves skepticism, and four ways to limit the damage.
A co-packer's quoted per-unit price can understate real landed cost by 36% once fixed per-run charges, setup fees, and MOQ economics are counted. How food and beverage brands should classify contract-manufacturing costs as COGS, handle turn-key vs. tolling arrangements, and avoid the 5–10 point gross-margin overstatement that misclassification causes.
How sign shops use job costing to price channel letters, vinyl, and wraps profitably — tracking direct materials, direct labor, labor burden (roughly 15%+ over base pay), and an hourly overhead rate, with a pricing formula and common profit leaks like unbilled design revisions and install overruns.
UPS and FedEx raised list rates 5.9% for 2026 and USPS raised Ground Advantage rates 7.8%, but small e-commerce shippers are seeing 10-20% higher bills because USPS cut its DIM divisor from 166 to 139, additional handling and delivery area surcharges rose 6.4-14% by zone, and surcharge eligibility thresholds widened.
How chaos engineering consultancies should split resilience-audit, game-day facilitation, automation build-out, and tooling-resale revenue into separate ledger accounts — including ASC 606 agent-vs-principal treatment for license pass-throughs, deferred revenue on fixed-fee audits, and per-engagement-type margin tracking.
Contribution margin is sales revenue minus variable costs — the per-unit number that drives pricing, break-even analysis, and product-mix decisions. Learn the formula, how it differs from gross margin, common calculation mistakes, and typical ratios by industry (70–90% for software, 25–50% for manufacturing).
