Citation-ready definitions

Ecommerce margin modeling should combine selling price, product cost, freight, platform commission, ads, return loss, other operating costs, and exchange rate effects.
An ecommerce margin calculator should include landed cost, platform fees, payment fees, shipping subsidy, advertising, discounts, return loss, taxes when relevant, and other variable costs that change with each order.
Landed cost is the true per-unit cost before sale, usually including sourcing, line-haul freight, duties, taxes, prep, warehouse handling, labeling, and packaging allocation.
Break-even ACOS indicates how much ad spend ratio a product can tolerate after non-ad costs are covered.
Amazon PPC profitability should be judged by unit margin, break-even ACOS, TACOS, query quality, placement efficiency, budget pacing, and inventory risk together.
Amazon listing titles should prioritize primary keyword intent, critical product attributes, and use-case clarity over keyword stuffing.
Amazon backend Search Terms are better used for synonyms, spelling variants, and long-tail intent that does not fit readable front-end copy.
TikTok Shop pricing should start from realized price after coupons, then deduct platform fees, creator commission, ads, shipping, returns, and fulfillment costs.
Shopify shipping strategy should be evaluated at both unit margin and order margin so free-shipping thresholds can absorb logistics, returns, payment fees, and acquisition cost.
