SellerSync

About

Stop doing Mercari busywork by hand.

SellerSync automates the repetitive tasks that eat a reseller's time every day: relisting expired items, dropping prices, promoting listings, and clearing your shop in bulk. Click once and it runs on its own, so you can spend your time sourcing and shipping instead of clicking through the same screens over and over.

WHAT IT DOES

Auto-Relist
Open your inactive listings page, click Run, and SellerSync reactivates every item for you. No more reactivating listings one at a time.

Bulk Delist
Deactivate your entire active shop in one click. Pause your store or clear out inventory in seconds instead of doing it item by item.

Price Drop Scheduler
Set a drop percentage in Settings, then click Run. SellerSync opens each listing, lowers the price, and saves it automatically, working through your whole shop while you do something else. It reads the live price on every item before applying the discount, so the new price is always calculated from the real number.

Auto-Promote
Promote your active listings back to back. Pick your style in Settings: a 72 hour sale, promote to all buyers, or send offers to people who liked your item.

Dashboard
See your active listing count and total views right inside the popup whenever you are on your Mercari listings page.

FREE VS PREMIUM

The Dashboard is free. Auto-Relist, Bulk Delist, Price Drop Scheduler, and Auto-Promote are included with Premium at $9.99 per month. Click Upgrade inside the extension to subscribe, and cancel any time.

YOUR DATA STAYS WITH YOU

SellerSync runs entirely in your browser. It does not collect your Mercari login, your personal information, or your payment details, and it has no servers of its own. Your settings are saved locally on your own computer. Read the full policy at sellersync.tinkrd.com/privacy/.

IMPORTANT

SellerSync performs actions on your own Mercari account that you are already able to do by hand. Use it responsibly and in line with Mercari's Terms of Service. Automation tools that interact with third party platforms carry inherent risk, so use at your own discretion.
