SellerChamp's channel integrations not just allows you to import and share listings among your marketplaces, but also maintain the quantity of the listings across the them.
In order to safeguard yourself from incurring additional insertion fees and from the listing to end, we recommend you enable the eBay out-of-stock option for all your Good'Til Cancelled - fixed price listings.
How this feature works?
When your listing quantity reaches 0 (whether due to sales on eBay or any other marketplace(s)), eBay will automatically hide that listing from all buyer searches. This prevents you from getting an order from an eBay buyer, even though there's no quantity in stock.
Using the out-of-stock option and keeping your listings hidden will allow those listings to retain their purchase and search history, so that when the item quantity is added again, over eBay or on any other marketplace (as long as you have your channel integrations configured) your listing will become available for sale on eBay again.
How to apply the out-of-stock option for all your Good 'Til Cancelled listings:
Step 1: Go into your My eBay > Account > Site Preferences
Step 2: Under the "Selling Preferences" click "Show" next to Sell Your Item form and listings
Step 3: Click "Edit" next to "Use the out-of-stock option"
Step 4: Select the checkbox, then click "Apply"
