Overview

If you already have live listings on Onceit and you want to start using Omnivore to manage your marketplace integration, you’ll need to handle your existing listings before you go live. 


What You Need To Know

  • Existing listings on Onceit may need to be removed before you start selling through Omnivore — it depends on how your marketplace account is currently configured.

  • Omnivore works closely with Onceit to determine the best approach for each retailer.

Steps to Prepare

  1. Tell Omnivore Support
    Let Omnivore’s integration and support team know you already have listings on Onceit, so they can advise you on the best next steps.

  2. Contact Your Onceit Account Manager
    Inform your Onceit Account Manager that you are planning to integrate with Omnivore. They can explain Onceit’s requirements and help you decide whether existing listings should be removed or handled in a specific way.

  3. Read Recommended Documentation
    Review guidance on managing existing marketplace listings, including Omnivore’s general existing listings FAQ and Onceit’s own seller support documentation.

Key Do's and Don'ts

        Do:

  • Let both Omnivore and your Onceit account manager know about your existing listings. 

  • Get advice before taking action — correct handling helps prevent listing issues after integration. 

        Don’t:

  • Don’t click Start Selling in Omnivore until existing listings are resolved — this can cause listing conflicts and errors. 

  • Don’t just make listings inactive or delete them without guidance — there may be specific steps that reduce issues with Omnivore and Onceit.
