Treecat Crosslisting Demo: How to Filter, Autofill, and List Faster
Treecat is built to help resellers manage inventory across marketplaces without the hassle of overselling. In this tutorial-style walkthrough, Michelle from Treecat shows how to use filtering, labels, tags, and two different listing views to crosslist items efficiently across supported marketplaces.
What Treecat Does for Resellers
Treecat is a crosslisting and inventory management tool designed to keep your listings in sync across marketplaces like:
- eBay
- Poshmark
- Mercari
- Whatnot
The key value is sales detection and auto-delisting. When an item sells on one platform, Treecat detects it and removes it from the others so you avoid double-selling.
Treecat also stands out because it uses a pay-when-you-sell model, with no monthly subscription, no token system, and no feature paywalls.
Before You Start Crosslisting
Before using Treecat for crosslisting, make sure you have the basics set up:
- Install the local agent on your PC or Mac
- Connect all of your stores
- Install the lightweight Chrome extension for login management
- Keep your computer on and out of sleep mode
These steps are important because Treecat relies on your local agent and active system access to detect sales and manage listings properly.
Using Filters, Labels, and Search to Find Items
One of the strongest parts of Treecat is its filtering system. You can use it to find items in several ways:
- Listed on one marketplace but not another
- Items with multiple quantity
- Archived items
- Items with custom labels or tags
- Listings by keyword, description, or custom SKU
Michelle also shows how to create custom labels in Settings > Profile. These labels can be added in bulk to selected items, making it easier to organize inventory by date, category, or any internal system you prefer.
Treecat also supports searchable fields like:
- Product name
- Description
- Custom SKU
- Labels
- Treecat notes
This makes it easier to manage large inventories and quickly locate the exact items you want to crosslist.
Two Ways to Crosslist in Treecat
Treecat offers two main crosslisting workflows:
1. Card View
In card view, you can filter items, select a group, and then use main actions to autofill them from one marketplace to others. Michelle prefers this method when working in a more visual, organized way.
2. Fast List View
Fast list view is better for larger batches. Michelle demonstrated selecting multiple items at once, autofilling them, checking the generated fields, and then listing them in bulk.
Both views allow you to:
- Review autofilled data
- Correct fields like condition, color, and price
- List items to marketplaces such as Mercari and Poshmark
- Track status as pending or completed
Treecat also uses intelligent queuing, so actions are processed sequentially and can be monitored in real time.
Why This Matters for Resellers
For resellers with growing inventories, Treecat’s workflow can save time and reduce mistakes. The ability to filter precisely, batch process listings, and monitor progress in different views gives sellers more control over their multichannel business.
Whether you prefer to work item by item in tabs or manage larger batches in fast list view, Treecat gives you flexible options for crosslisting and inventory management.
