Multi-platform seller FAQ
Shopify has the lowest per-transaction fees (0–2% on top of payment processing) but you pay a monthly plan ($29–$299) and drive your own traffic. Among marketplaces, TikTok Shop's 6% referral is lowest — but creator affiliate commissions (10–30%) often exceed Amazon's 15% referral on attributed sales.
Walmart often wins on bulky home and sporting goods because WFS fulfillment runs $1–2 cheaper than FBA on 1–3 lb items, and Walmart Connect CPCs are 30–40% lower. Amazon wins on electronics and high-velocity Prime SKUs where FBA conversion rates justify the higher fee stack.
Yes — if your margins support both fee structures. TikTok drives discovery and impulse buys; Amazon captures search intent. Run each through this comparison first: TikTok affiliate orders often net 5–10 points less than organic TikTok sales on the same price point.
