Current analyses

• E-commerce Profit Sensitivity Analysis — Modeled scenarios showing how refund rate, advertising cost, and product cost change expected profit, margin, and break-even advertising thresholds.
• Product Price vs Profit Analysis — Modeled selling prices against a fixed cost structure to show expected profit, margin, break-even price, and target-margin pricing.
• Selling Channel Cost Comparison — Same hypothetical product economics across direct e-commerce, Shopify, Etsy, and TikTok Shop assumptions—comparing fee structure effects, not crowning a winner.
