The short version

  • Only Poshmark has a free tier, so it costs nothing to try first.
  • Each has a real cost: BigCommerce plans are gated on annual online sales, so a strong year pushes you into a higher tier and a higher subscription even though your traffic, catalogue and resource usage are unchanged.; 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.
  • They diverge on capability: BigCommerce covers No platform transaction fee, Poshmark covers Social sharing feed.
  • 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.

BigCommerce

  • Plans are gated on annual online sales, so a strong year pushes you into a higher tier and a higher subscription even though your traffic, catalogue and resource usage are unchanged.
  • There is a documented ceiling on the number of variants a single product can have, which breaks configurable, made-to-measure and heavily optioned catalogues and forces awkward workarounds such as splitting one product into several listings.
  • The application marketplace is much smaller than the largest competitor's, so a specific integration or niche feature is more often a custom build, and custom builds are the line item that quietly exceeds the platform cost.
  • Theme customisation past the visual settings means Stencil, Handlebars templates and a local command line workflow, so changes that look small to a marketing team still require a developer and a deployment.
  • Migrating out moves products and inventory reasonably well and moves the things that matter badly, since customer passwords cannot be exported in usable form, order history rarely transfers intact, and reviews and URL structure have to be rebuilt with a redirect map you must produce yourself or lose the search traffic.

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.

Answered from the vendors’ own pages

BigCommerce: Does BigCommerce charge transaction fees?

No, and it does not surcharge third party payment gateways either. Revenue affects the price through plan sales thresholds instead.

Poshmark: How much does Poshmark charge sellers?

A flat 2.95 dollar fee on sales under 15 dollars, and a 20 percent commission on sales of 15 dollars or more.

BigCommerce: What happens when I exceed my plan's sales threshold?

You move to the next plan tier. Model this at your projected growth rate, because the increase is driven by revenue rather than by usage.

Poshmark: Who owns Poshmark?

Naver, the South Korean internet and search company, acquired Poshmark in 2023.

BigCommerce: Is the app ecosystem large enough?

It covers the common integrations. For anything niche, assume a development project rather than an install, and price that in before comparing subscriptions.

Poshmark: Do I have to actively promote my listings?

Not strictly, but the app visibility algorithm favours accounts that regularly share and engage, so passive listing tends to sell more slowly.

BigCommerce: How hard is it to leave?

Products export cleanly. Customer passwords, order history, reviews and SEO URLs do not. Build the redirect map before you cut over, not after traffic drops.
