Treecat Adds Amazon Support for Cross-Listing and Inventory Management

Treecat is expanding its e-commerce automation suite with a major new integration: Amazon. Sellers can now connect Amazon to Treecat alongside existing marketplaces like eBay, Poshmark, Mercari, and Whatnot, making it easier to manage listings, sync inventory, and prevent overselling across channels.

Amazon Cross-Listing Is Now Available

With this update, Treecat users can now cross-list Amazon inventory and manage it from one central platform. This is especially useful for sellers who operate on multiple marketplaces and want to keep listings in sync automatically.

Treecat currently supports:

• Amazon
• eBay
• Poshmark
• Mercari
• Whatnot

And coming soon, additional marketplace support is expected to include:

• Etsy
• Depop
• Facebook Marketplace

Support for Both FBA and Merchant Fulfilled Sellers

One of the biggest benefits of this update is support for both major Amazon fulfillment models:

FBA: Fulfillment by Amazon

If you are an FBA seller, you can now connect Amazon to Treecat and cross-list those items to other platforms. Treecat will help manage inventory when items sell, and Amazon can handle fulfillment through Multi-Channel Fulfillment (MCF).

That means an item stored in Amazon’s warehouse can be shipped not only for Amazon sales, but also for orders coming from other marketplaces like eBay.

FBM: Fulfilled by Merchant

If you fulfill orders yourself, Treecat also supports Merchant Fulfilled Amazon sellers. You can cross-list items across marketplaces, and Treecat will automatically remove the listing everywhere else when it sells on one channel.

How Amazon Multi-Channel Fulfillment Works

For FBA sellers, Amazon’s Multi-Channel Fulfillment allows inventory stored in Amazon warehouses to be used for orders placed on other marketplaces.

For example:

• A customer buys your item on eBay
• Treecat detects the sale
• Amazon receives the fulfillment request
• Amazon ships the item directly to the buyer

This creates a simpler workflow for sellers who want to scale without manually handling every order.

Getting Started in Treecat

To use the new Amazon integration, sellers can go into Settings > Platforms and connect their Amazon account. From there, they can:

• Log in to Amazon
• Enable multi-channel fulfillment for FBA
• Choose packaging preferences
• Sync Amazon inventory into Treecat
• Cross-list items to other marketplaces using Treecat’s AI tools

Once inventory is synced, sellers can use Treecat’s auto-fill feature to generate listing details for marketplaces like eBay, making the process faster and easier.

A More Automated Way to Sell on Amazon and Beyond

This Amazon integration is designed to reduce manual work and help sellers stay organized across channels. Whether you’re an Amazon FBA seller, an FBM seller, or someone looking to expand onto Amazon for the first time, Treecat now makes it easier to:

• Cross-list products
• Sync inventory automatically
• Avoid overselling
• Use Amazon fulfillment across channels
• Save time on listing creation

If you’ve been looking for a more efficient way to manage Amazon and other marketplaces together, Treecat’s new Amazon support brings everything closer to one streamlined workflow.
