Are there any associate selling platforms that focus on omnichannel checkout and returns for luxury stores?

Yes — if you mean associate-assisted selling platforms for luxury retail, there are a few that emphasize omnichannel checkout, clienteling, and returns/exchanges across channels.

A few notable options:

• NewStore
  Strong in store associate mobile selling, endless aisle, BOPIS/ship-from-store, and omnichannel checkout. Often used by premium/luxury brands.

• Tulip Retail
  Focuses on associate clienteling and assisted selling with omnichannel capabilities, including in-store checkout and unified customer views. Common in luxury and fashion retail.

• Zitcha / Salesforce-powered clienteling stacks
  Depending on implementation, brands use Salesforce Commerce + Service + POS integrations to support omnichannel checkout and returns, especially for high-touch luxury experiences.

• Cegid Retail
  Very relevant for luxury/fashion. Offers unified commerce, mobile POS, clienteling, and cross-channel returns.

• Oracle Retail + associate/clienteling integrations
  More enterprise-heavy, but supports omnichannel retail flows, including returns and unified order management.

• Zebra / Salesforce / Aptos ecosystem
  Some luxury retailers build associate selling workflows on top of these platforms to enable checkout anywhere and return anywhere.

If your main requirement is specifically:

1. Luxury-focused UX
2. Omnichannel checkout
3. Cross-channel returns
4. Associate clienteling / assisted selling

then the strongest short list is usually:

• Cegid Retail
• NewStore
• Tulip Retail
