Frequently asked questions
- How do I know if a product is profitable?
- Paste the Amazon or eBay listing URL into Parseflow and enter your buy price. Parseflow reads sell price, marketplace fees, inbound costs, and price history, then shows net profit, margin, ROI, and a Strong, Mixed, or Weak signal before you buy stock or dropship.
- How do Amazon fees affect profit?
- Amazon referral fees (typically 8–17% by category), FBA fulfillment, inbound shipping, and storage reduce your net margin. Parseflow estimates these from the listing so you see true profit after fees — not just sell price minus COGS.
- How do I calculate margin on a reselling product?
- Margin = net profit ÷ sell price × 100. Net profit is sell price minus COGS, inbound shipping, marketplace fees, fulfillment, and other per-unit costs. Parseflow calculates this automatically when you paste a product link.
- What is a good ROI for reselling?
- Many arbitrage sellers target 25–40%+ ROI after all fees, but acceptable ROI depends on capital, sell-through speed, and risk. Parseflow shows ROI alongside margin and demand signals so you can compare products before sourcing.
