Where each one falls short

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

Poshmark

  • The flat 2.95 dollar fee on sales under 15 dollars takes a large proportional bite out of cheap items, making Poshmark a poor fit for offloading low-value pieces compared with a flat percentage competitor.
  • The 20 percent commission on higher-value sales is above Mercari flat 10 percent rate, so a seller moving pricier items pays materially more per sale unless the social discovery features generate enough extra volume to compensate.
  • Visibility in the app depends heavily on active sharing and engagement, so a seller who lists items and does not regularly promote them tends to see far fewer sales than one who does, turning selling into ongoing work.
  • Naver ownership since 2023 means Poshmark now reports as part of a larger Korean internet conglomerate rather than as an independent company, which can affect roadmap priorities and regional focus.
  • Buyer protection through Posh Protect requires timely reporting and photo evidence, and disputes over item condition still rely on subjective judgement between buyer and seller.

Square

  • Plus plan pricing not specified in documentation
  • Processing fees differ by tier but exact rates not detailed
  • Free plan pricing mentioned but specific features for Plus unclear
  • Text marketing charged at 3¢ per message after first 500 included
