Considering ChannelEngine?
Marketplace listing built only for fashion brands.
ChannelEngine serves many kinds of sellers. Osello serves fashion brands on Shopify selling on Nordstrom, Macy's, Bloomingdale's and Target Plus, with AI agents that build each listing to the retailer's requirements.
About ChannelEngine
Marketplace integration software. Its site says "Connect once. Sell everywhere." across 1,300+ channels, with ready-made integrations for Shopify, Adobe Commerce, SAP, Microsoft Business Central and NetSuite.
Why listings on department-store marketplaces are hard
None of these problems are your product. All of them are the retailer's specification.
01
Nordstrom publishes 250 required fields. Macy's publishes 1,077.
Size type, size standard, NRF color code, material composition percentage, country of manufacture. None of them exist in Shopify, and each retailer names them differently.
02
The same photo passes one retailer and fails the next.
Each marketplace sets its own aspect ratio, background and alternate-image rules. A catalog shot for your own site needs re-cropping and re-backgrounding for every destination.
03
One dress in six colors is six Shopify products. The marketplace wants one listing.
Shopify stores split colorways into separate products. Retailers require one style with six colorways and a full size run under each, or the style is rejected.
Where Osello differs from ChannelEngine
AI agents build and optimize your listings
You connect Shopify. An agent writes each retailer's required fields per listing, with a confidence score on every answer, instead of you configuring feed rules.
Agentic image editing
Backgrounds whitened, aspect ratios corrected per marketplace, alternate images reordered. No re-shoot, no retouching queue.
Approved in a fraction of the time
Before Osello, brands report 80 days to a first listing. Universal Standard's first live listing came 5 days after install, with 93% approved on first submission.
Built for fashion brands, not everyone
Apparel, footwear, accessories and baby. Size runs, size types, colorways and category-specific fields are the default, not a configuration.
Combine color-separated products into one listing
Six Shopify products for the same dress become one marketplace listing with six colorways and every size under each.
Real onboarding, not a ticket queue
A founder is on your onboarding calls. You get a person who knows your catalog, not a support SLA.

Switching
Moving from ChannelEngine to Osello
We will not put a date on your catalog before we have seen it. On the demo we walk through your live listings and tell you what the cutover would involve.
01
Connect Shopify and your marketplace accounts
Osello reads your catalog from Shopify and your live listings from each retailer. Nothing is submitted yet.
02
Listings build alongside your current setup
Agents map every style to each retailer's requirements. You review the result against what is live today. Your existing listings keep selling throughout.
03
Cut over once the mapping is verified
Listed SKUs stay the same, so nothing duplicates on the marketplace. Orders keep landing in Shopify the way they already do. Then you cancel the old tool.
Pricing
From $499 a month. Flat.
Tiered by live SKUs and marketplace volume. No revenue share, no per-order fee, no onboarding fee. The full table, every limit and every plan is public.
