Imagine one tote on four shops. And only one left on the shelf.
Without QuickSync
It sells on Shopify. The other three don’t know.
Etsy, eBay and Amazon still say 1 left. Nothing told them.
Then someone buys it on Amazon. Two orders for one bag.
Your stock count is now minus one.
So you fix it by hand. Then you cancel, apologise and refund.
Etsy and eBay go to zero one login at a time. Amazon counts the cancellation against your account health.
Buyers remember. One star for an order you couldn’t fill.
Now with QuickSync. All four shops share one stock count.
It sells on Shopify. Nobody buys it twice.
Etsy, eBay and Amazon show sold out within seconds. The 2:16 buyer on Amazon never gets to check out.
One order, one box. On its way the same afternoon.
Two days later it’s at the buyer’s door.
Buyers remember this too. Five stars on Shopify.
Restock once. Every shop follows.
Add 3 in Shopify, and Etsy, eBay and Amazon show 3 left within seconds.
- Every shop is set from one master count: the stock on your shelf.
- Each shop connects to QuickSync, not to the others, so your eighth shop syncs like your first.
- If Amazon or eBay is down, we hold the update and retry until it goes through.
- You can see which sale moved a number, and when.
Sell everywhere. Oversell nowhere.

Titles, photos, sizes and prices come from the shop you pick as the main one. Anything a marketplace still needs is flagged before you publish, and nothing goes live until you’ve looked at it.
Pack from one screen
Orders from every shop arrive matched to the right product. Tracking numbers go back to the six channels that accept them, and orders can go straight to QuickBooks.

What sellers say
“Just installed the QuickSync app. This saved soooo much time rather than keying in over 300 Shopify variants into Etsy. Their online consultant answered a few questions I had and the integration was seamless. We integrated all Shopify items into Etsy in minutes and already up and running! Great app to have! Great job QuickSync team!”
“i love this app. it makes my shopify so much easier. also support helps right away when needed. I had a couple issues at the beginning with sold items not being removed from the store. they fixed it. thank you”
“QuickSync has worked great for us and solved a huge headache trying to manage products between two platforms. Omar is extremely helpful”
Questions sellers ask
Which integrations does QuickSync support?
Thirteen: Shopify, Amazon, Etsy, eBay, WooCommerce, Square, Clover, TikTok Shop, Squarespace, Lightspeed and Wix for stock and orders, plus QuickBooks Online and Xero for the accounting side. Every one has its own page with the setup steps and the limits written out.
How does QuickSync stop me overselling?
Two ways. One master count is pushed to every channel as soon as we know about a sale, and safety stock holds a few units back where you choose, so Amazon shows nine when you have eleven and the last two are never sold twice. If two channels do sell the last unit at the same moment, the first one gets it and the second is held for your decision, with no silent oversell.
Do I have to re-list all my products?
No. We match up your existing listings automatically and show you a short list of whatever we could not, so you fix a handful of items instead of starting over.
Can I try it without letting it change anything?
Yes, and most people should. Let it watch for a few days, check the numbers agree, then let it start making changes one channel at a time.
What if a marketplace goes down?
We hold the update and keep trying until it goes through. You get a single message, not one per retry, and you can send it again yourself from the activity log.
Is there a limit on orders?
No. Order volume never changes your bill. A thousand orders a day on the Lite plan costs the same as ten.
How much does QuickSync cost?
Your plan price covers two connected shops, and every shop after that adds it again. Your catalogue size decides which plan you are on. Lite is $19 a month for 1,000 items, so two shops is $19 and four is $57. Most sellers land on Pro at $29, which adds product and order sync. Eight shops is the limit on every plan. Every plan starts with a 14-day free trial and no card. If you do nothing after the trial, syncing stops and nothing is removed from your shops.
