How EZListerPro Works

From photo to sale in minutes — here's exactly how to list and sell across multiple marketplaces.

Step 1

Snap a Photo

Take a picture of any item you want to sell. Our AI instantly identifies the product, brand, condition, and suggests a competitive price.

Tips

  • Use good lighting for best AI accuracy
  • Include brand labels or tags if visible
  • Take multiple angles for higher-value items
Step 2

Review & Customize Listings

AI generates optimized titles, descriptions, and pricing for each marketplace. You can edit anything before publishing.

Tips

  • Each platform gets a tailored listing
  • AI adjusts tone for eBay vs Mercari vs Poshmark
  • Set your own price or use AI suggestion
Step 3

Connect Your Marketplaces

eBay connects directly via API for automatic posting. For Mercari, Poshmark, OfferUp, and Craigslist, install our browser extension.
