The short version

  • Only Mercari has a free tier, so it costs nothing to try first.
  • Each has a real cost: ChannelAdvisor now operating as Rithum; the pricing page publishes no figures and routes prospects to "request a demo" and "speak with commerce experts" instead; Mercari the flat 10 percent commission plus payment processing fees applies even to very low-value items, so selling something for a few dollars can leave the seller with proportionally little after fees and packaging.
  • They diverge on capability: ChannelAdvisor covers Marketplace integration, Mercari covers Flat seller commission.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ChannelAdvisor

  • Now operating as Rithum; the pricing page publishes no figures and routes prospects to "request a demo" and "speak with commerce experts" instead

Mercari

  • The flat 10 percent commission plus payment processing fees applies even to very low-value items, so selling something for a few dollars can leave the seller with proportionally little after fees and packaging.
  • Shipping is the seller's responsibility to arrange and package correctly, and disputes over item condition or damage in transit are common friction points in buyer-seller resolution.
  • Instant payout carries its own fee on top of the selling and processing fees already deducted, so getting money out quickly costs more than waiting for standard transfer.
  • Buyer protection and authenticity verification are limited outside the specific luxury authentication programme, so counterfeit risk on unverified categories rests largely on buyer judgement of listing photos and seller ratings.
  • Market depth and typical sale prices vary significantly between the Japan and US versions of the app, and the two operate as largely separate marketplaces despite the shared brand.
