Where each one falls short

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

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.

Square for Retail

  • Limited customer support with primarily email and online forums, slow response times for urgent issues
  • Internet connectivity required for normal operations; weak signal impacts transaction processing and experience
  • Restricted to Square's payment processing with higher transaction fees compared to some competitors
  • Limited to iOS devices and Square's proprietary hardware, excluding Android or third-party devices
  • Limited advanced retail capabilities and deeper third-party integrations compared to enterprise POS systems
