Multichannel inventory sync software Sold on Shopify. Still for sale on Amazon.
Sell in ten places and keep one stock count. QuickSync corrects every shop from it in seconds. On eBay, Etsy and Squarespace we check every few minutes rather than being told, and safety stock covers that gap.

One master stock count. Every sales channel copies it.
Most multichannel inventory sync tools try to keep each pair of shops in step with each other, which gets tangled fast. QuickSync keeps one master number: the stock you actually have on the shelf. Every sales channel is updated from it.
A sale just came in, so the count drops by one and every shop is corrected to match. Most shops update in seconds. eBay, Etsy and Squarespace are on a short poll, and safety stock covers that gap.
One number everyone follows
Every shop is updated from the same count. If a number ever looks wrong, you can see exactly which sale changed it and when.
The tenth shop is as easy as the second
Each shop connects to QuickSync, not to all the others. So adding one more never makes the rest harder to manage.
A marketplace having a bad day costs you nothing
If Amazon or eBay is down, we hold the update and keep trying until it goes through. Your master count is never wrong in the meantime.
Somebody buys on Etsy. Here is what happens next.
Scroll and the timeline follows along. This is the real order of things, including the bits that take a little longer.
A buyer checks out on Etsy
Etsy has no way of telling us the moment it happens, so we go and look every few minutes. This one was found on the next check.
Your master count drops to 41
You had 42, now you have 41. That is the number every other shop will be corrected to.
The fast shops update straight away
Shopify, Amazon, Square, Clover and WooCommerce get the new count as soon as we have it. Most are done in well under a second.
eBay lands a second or two later
eBay caps how often anyone can send it a change, so the write takes a second or two. That is still seconds, not the couple of minutes we wait when eBay is the shop that sold.
The order lands in your one list
Already matched to the right product, with the Etsy order number attached, ready for whoever is packing today.

Overselling, stockouts and the morning spreadsheet all come from one thing: every sales channel keeping its own count.
| Before QuickSync | With QuickSync |
|---|---|
| The last one sells on Etsy and eBay in the same hour | Safety stock on the slower channels stops the last one selling twice |
| Typing the same stock numbers into every shop each morning | One count, sent everywhere, seconds after the sale reaches us |
| Changing a price means editing the same product five times | Change it once and each shop gets the price you set for it |
| Orders scattered across six dashboards until month end | Every order in one list, already matched to the right product |
| A cancelled order leaves your numbers wrong until someone spots it | A refund puts the stock back and tells every shop |
Three jobs, and you do not have to take all three
Stock sync is the one people connect for. Listings and orders wait until you switch them on.
When a number looks wrong, you can see what moved it
Open any change and it tells you the order behind it, the sales channel that reported it, and what the count was before. Most sync tools just show you the new number and leave you to work out the rest.
- Hold back safety stock on any channel, so the last one is much less likely to sell twice
- Stock across several places, added up or split however you want
- When two sales clash, we ask you rather than quietly picking one
- A full history of every change, downloadable as a spreadsheet

Draft
Amazon's fees are higher, so your price rule adds 8% there.
Write the product listing once, publish it everywhere
Titles, descriptions, photos, sizes and prices all come from whichever shop you pick as the main one. If a marketplace needs something extra, we tell you before we publish, not after it gets rejected.
- Charge more where the fees are higher: a percentage, a mark-up or a set price
- Your existing listings get matched up automatically; we show you anything we could not
- Bundles and multipacks take the right amount off each item inside
- Nothing goes live until you have looked at it
Every order in one list, whatever the channel
Every order arrives in one list, already matched to the right product, so packing does not mean six browser tabs. Tracking numbers go back to the shop the order came from, on the six channels that accept one.
- Tracking numbers go back automatically to the six channels that take them. Amazon, Square, Clover and QuickBooks have no field for one
- Refunds and cancellations put the stock back on every channel
- Send it all to QuickBooks, already matched to the right order

The parts you only find out you needed in month two
Every one of these exists because a seller ran into it and told us.
Safety stock
Hold a few back on each shop so two people cannot buy the last one at the same moment.

If two shops sell the last one within seconds of each other, we stop and ask you what to do.

What sellers say
Three reviews merchants left on the Shopify App Store, quoted word for word. The name, country, rating and date are as published, and every card links to the original.
“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 first
How fast is real-time inventory sync, really?
Sending a new count to a shop is under a second nearly everywhere, and a second or two on Amazon and eBay when they are busy. Finding out that a shop sold something itself is the part that varies: most channels tell us the moment it happens, and eBay, Etsy and Squarespace get looked at every couple of minutes instead. Safety stock is what covers that gap.
Which integrations does QuickSync support?
Eleven: Shopify, Amazon, Etsy, eBay, WooCommerce, Square, Clover, TikTok Shop, Squarespace and Lightspeed for stock and orders, plus QuickBooks Online for the accounting side. Each one has a setup guide on its own page.
How does QuickSync stop me overselling?
Two ways. One master count is pushed to every channel as soon as we know about the sale, so the window in which a second buyer can reach the same item is seconds rather than hours. Two channels do not announce a sale to us at all: we check eBay every two minutes and Etsy every five, so on those the clock starts at our next look. That is exactly what safety stock is for: hold some back on the slower channels, so Amazon shows nine when you have eleven and the last two are never sold twice. If two channels do sell the last unit within the same second, the first one gets it and the second comes to you as a question rather than a 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 are fixing a handful of items rather than starting again.
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 one message about it rather than one per attempt, 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 integrations is the limit on every plan. Every plan starts with a 14-day free trial and no card.
