Your fashion catalog.On every marketplace.Listed in minutes.

Stop rebuilding listings for every marketplace. Apparel isn't general merchandise. Osello lists size runs, colorways, and photos the way those retailers sell, inventory synced from your Shopify store.

Works with

A dress is not a toaster.
So why list it like every other category?

  1. Photos

    White studio and on-figure shots.
    Each store gets the crop its product page uses.

  2. Sizes and colorways

    One style, a size run, and colorways, merged into one listing.
    Not a bunch of separate SKUs.

  3. Returns and inventory

    Fit returns restock in Shopify.
    Every marketplace gets that stock back.
