A Familiar Story

What happens when eBay and Etsy aren’t connected

7:30 PM. Vintage lamp sells on eBay

You only had one. eBay marks it sold. Etsy still shows it as available. You don’t notice until tomorrow.

11:45 PM. Same lamp sells on Etsy

A buyer snaps it up while you sleep. Two customers, one item, zero way to fulfill both orders.

Next morning. Cancellation and apology

You cancel the Etsy order, refund the buyer, and write an awkward apology message. Etsy notes the cancellation on your account.

One week later. 2-star review

“Sold me something they didn’t have. Very disappointing.” Your shop stats drop. Search placement follows.

With Commerce Kitty

7:30 PM. Vintage lamp sells on eBay

Commerce Kitty instantly marks the item as out of stock on Etsy. Quantity drops to zero within seconds.

11:45 PM. Etsy shows the item as sold out

The late-night browser sees “Sold out” on Etsy. No second sale. No cancellation needed. You sleep soundly.

How It Works

Connect both marketplaces in minutes

No developer, no spreadsheets, no ongoing manual work. Just connected marketplaces.

1

Connect eBay

Authorize Commerce Kitty with your eBay account. All active listings and stock levels import automatically.

2

Connect Etsy

Connect your Etsy shop the same way. Commerce Kitty maps your products across both marketplaces.

3

Sell on both freely

When anything sells on either platform, Commerce Kitty updates the other within seconds. Automatically, always.

Connect Both Marketplaces

I sell vintage finds on both eBay and Etsy. Overselling used to happen at least once a month. Since connecting Commerce Kitty I’ve had zero incidents. It just works in the background and I don’t think about it anymore.

FAQ

Questions about eBay and Etsy inventory sync

Does it work with one-of-a-kind items?
Absolutely. this is where sync matters most. When you have a single unique item listed on both eBay and Etsy, Commerce Kitty ensures the moment it sells on one platform, it goes to zero (or gets delisted) on the other instantly.
How fast does inventory update between platforms?
Within seconds. Commerce Kitty listens for real-time sale notifications from both eBay and Etsy and updates inventory immediately. There’s no batch processing or delay that could leave a window for double-selling.
Do I need to change how I list items on eBay or Etsy?
No. You keep creating listings the same way you always have. Commerce Kitty connects to your existing listings and syncs inventory between them. Nothing about your listing workflow changes.
What if I sell on more platforms than just eBay and Etsy?
Commerce Kitty also supports Shopify, Amazon, WooCommerce, and BigCommerce. You can add them all to the same account and everything stays in sync from one central inventory.
Is there a free plan?
Yes. The free plan includes full inventory sync between eBay and Etsy up to a monthly order limit. No credit card required to start. Paid plans are available as your business grows, with no contracts.
