Three steps. You stay live.

01

Connect Shopify

One click. Catalog, variants, images, inventory. No export, no spreadsheet.

02

We build the listings

Agents write the fields, merge colorways, and crop images to each retailer. You approve before anything submits.

03

Cut over when it is ready

Your live listings stay up. We switch the connection after you have seen the mapping work. Then add the next marketplace from the same catalog.

So, who is Osello?

Osello is the marketplace integration platform built for fashion brands. One Shopify connection. Agents write the listings, merge colorways, crop images to each retailer, and resubmit rejections. You keep the accounts you already have.

Software does the heavy lifting

Products, imagery, inventory, and orders sync between Shopify and the marketplaces you already sell on. The listing work leaves the spreadsheet.

Fashion is the specialty

Size runs, colorways, seasonal drops, imagery standards. Universal Standard, Noli, and Furniq UK run catalogs through it.

Already live, then everywhere

Keep Nordstrom, Macy's, Target+. Add the next retailer from the same catalog. You are not reapplying.

Nothing goes dark while you move.

The question everyone asks first, so here it is before you have to.

  1. Your live listings stay live.

    We build alongside your current setup and cut over once the mapping is verified, not before.

  2. Your marketplace accounts stay yours.

    You are not reapplying. Nordstrom, Macy's, Target+ — the seller accounts do not reset. This is a connection change.

  3. In-flight orders keep flowing.

    Orders land in Shopify the way they already do, throughout.

How this compares to what you're on now.

Most brands reach us from one of two places. Here is where the difference actually shows up.

Describes the two models brands most often move to Osello from, not any single provider. Commercial terms vary; the agency row describes the onboarding-fee-plus-commission arrangement we see most often in fashion.

Software, not a percentage of your sales.

Agencies charge an onboarding fee, then a commission on every order, forever.

Osello is a flat monthly fee. You keep 100% of what you sell.

Others will manage your marketplace listings. We do it without taking a cut of the orders you already win.
