QuickBooks Online now requires choosing between FIFO and Moving Average Cost inventory valuation and adds bills of materials with manufacturing orders. How MAC recalculates a blended unit cost on every receipt, why the costing choice is effectively permanent, and the bookkeeping mistakes — stale BOMs, untracked WIP, missing overhead — that quietly erode manufacturer margins.
With gold near $4,200/oz in mid-2026, jewelry makers who cost pieces at historical purchase price lose margin on every sale. Recipe-based COGS — a fixed bill of materials, labor, and overhead per design, repriced at current metal replacement cost — plus channel-specific markups (2x direct, 3–4x Etsy, wholesale at 25% of retail) keeps pricing and books accurate.
Only 3% of small importers still lack a tariff mitigation strategy in 2026, down from 57% waiting it out in 2025. Five bookkeeping moves protect margins — capitalize duties into landed cost instead of expensing them, scenario-model your top 20% of SKUs, track the carrying cost of buffer stock, price product-by-product, and record country of origin per batch.
House flippers are almost always IRS "dealers," not investors — flip profits are ordinary income on Schedule C plus 15.3% self-employment tax, often a combined rate over 40% versus the 15–20% capital gains rate flippers expect. How the Winthrop factors decide dealer status, why rehab costs must be capitalized into COGS, and four strategies (including an S corp election) that reduce the hit.
Carpet cleaning chemistry should run 5–7% of revenue, a $25,000 truckmount costs about $10 per operating hour in wear, and drive time between jobs is the biggest hidden margin leak. How to book chemistry, trucks, and routes as three separate cost centers.
The Federal Reserve's 2025 Small Business Credit Survey finds 80% of tariff-paying small firms raised prices, 60% absorbed costs into margins, and 44-47% plan further increases — a "trickle up" pattern that means input costs haven't finished rising.

June 2026 CPI fell 0.4% — the largest monthly drop since April 2020 — cutting annual inflation to 3.5%, but core prices were flat and producer inflation still runs 5.5%. What the CPI/PPI gap means for small-business supplier costs, tariff pass-through, and fall contract negotiations.
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.
The SAFE Banking Act was reintroduced in June 2026 with bipartisan Senate and House sponsors, after passing the House seven times since 2019 and dying in the Senate each time. Roughly 70% of U.S. cannabis businesses still operate in cash, paying $2,000–$7,500 in monthly banking fees when they can find a bank at all. Here's what the bill would change, why it keeps failing, and how operators can protect themselves now with cannabis-friendly banks, reduced cash exposure, and audit-ready books under Section 280E.
Cannabis got Section 280E relief when medical marijuana moved to Schedule III in April 2026, but Colorado's 34 licensed psilocybin healing centers are still fully subject to it. Here is how 280E limits deductions to COGS, why facilitator session labor is the contested cost category, and how to structure a chart of accounts, deferred revenue, and cash controls for a Schedule I business.
