Common questions
How do I set up the Chrome extension?+
Install Omventa Crosslister from the Chrome Web Store, click its icon in your browser toolbar and sign in with your Omventa account. Then use the Connect buttons in the popup to link Mercari and Poshmark. You need an active Omventa subscription (or free trial) to publish.
The extension says I'm not signed in, or my marketplace shows as disconnected.+
Open the extension popup and sign in again, then reconnect the marketplace. Make sure you're logged in to Mercari or Poshmark in the same Chrome browser. If a marketplace signs you out, the connection has to be refreshed.
My listing is stuck on “getting listed”.+
Mercari and Poshmark listings are published by the extension from your own browser, so Chrome needs to be open with the extension signed in. Keep the browser open for a minute or two. If the listing fails, open it in Listings, fix any error shown and republish.
How do I connect or disconnect a marketplace?+
Go to Marketplaces (or Settings → Marketplace Connections) in your dashboard. eBay and Depop connect through their own sign-in pages; Mercari and Poshmark connect through the Chrome extension. Disconnecting removes the stored connection.
How do I manage my subscription or buy AI credits?+
Go to Settings → Billing. You can start or change a plan, buy AI credit top-ups and open the billing portal to update your card, download invoices or cancel.
How do I delete my account and data?+
Email us from the address on your account and we’ll delete your account and associated data. See our Privacy Policy for details.
