BaseLinker Integration Expert Required

I’m looking for an experienced BaseLinker expert to help me resolve integration and inventory syncing issues.

Here’s the current setup:

BigCommerce is our main hub with all the products listed.

Selling Channels: Amazon, eBay, Etsy .

We’re using BaseLinker to manage inventory and orders across platforms.

What I Need:

Ensure all inventory from BigCommerce is correctly synced to BaseLinker.

Set up proper integration from BaseLinker to the selling channels: Amazon, eBay, and Etsy.

Eventually add Shopify as a selling channel through BaseLinker as well.

The Problem:

I’ve tried to list items through BaseLinker, but it's not working as expected.

I'm not sure what's wrong – settings, mapping, or API connections.

What I Expect From You:

Troubleshoot and resolve current BaseLinker setup issues.

Guide me through the proper configuration and best practices.

Ensure everything is fully connected and syncing correctly.

Help document or explain the steps so I can manage it going forward.

If you have experience with BaseLinker and multi-channel integrations (especially with BigCommerce, Amazon, eBay, Etsy, I’d love to work with you.
