Auto-delist and inventory sync · Updated October 9, 2026

How do I link existing listings across marketplaces and keep quantities in sync?

You do not have to relist anything. Treecat imports the listings already on your marketplaces, and Inventory → Matching suggests which listings are the same item. Accept a suggestion to link them, and from then on a sale on one marketplace delists the others. Fix Duplicates cleans up repeats, and Confirm Quantity pushes the right quantity to every live listing.

Start from what you already have

When you connect a marketplace, Treecat imports your active listings and sales history, then keeps checking for new listings you create directly on the marketplace. Importing is free and there is no item limit.

Link the same item across marketplaces

  1. Open Inventory → Matching and click Calculate.
  2. Review the suggested groups under To review. Each group shows the listings Treecat thinks are the same item.
  3. Click Accept & link on each correct group, or Accept High (+90%) to accept all high-confidence suggestions at once.
  4. Click Dismiss on a wrong suggestion. It only removes the suggestion, never a listing.

Linked items are treated as crosslisted: auto-delist protects them, and their sale is billable.

Clean up duplicates

Inventory → Fix Duplicates finds repeated listings within a marketplace account. Mark the one to keep and approve, and Treecat delists and deletes the rest.

Keep quantities consistent

  • Each sale lowers the item’s available quantity by the quantity sold. At zero, the other listings are delisted.
  • If quantities have drifted, select items in Inventory or Sales and use Confirm Quantity. Treecat pushes that quantity to every live listing; agent-based marketplaces update over the next few minutes.
  • Each item’s Events timeline shows what was updated and when.

FAQ

Frequently asked questions

Do I need SKUs to link listings?

No. Treecat matches listings by their content and you confirm the matches. Once linked, they share one inventory item and quantity.

Do I have to recreate my listings to use Treecat?

No. Import them and link them with Matching.
