Where each one falls short

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

KORONA POS

  • Inventory counts and stock management require the $79 Retail plan, so the $59 Core plan is checkout without stock control
  • Five separate modules are charged on top of the plan, at $10 per terminal for food service, $10 per terminal for invoicing, $50 per gate for ticketing, $30 per franchise and $45 per token for custom API integrations
  • Integration pricing is per token rather than per account, so several integrations multiply the cost
  • Advanced stock management and movement reporting require the $99 Plus plan

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.
