We built QuickSync because keeping one stock count straight shouldn't be a job

Selling in five places is easy now. Knowing how many you actually have left is not. QuickSync exists to make that one number correct everywhere, without anyone having to remember to update it.

14 days, no credit card · nothing changes until you switch it on

What QuickSync does
  • One master stock count across every connected shop
  • Listings copied from the shop you already run
  • Orders collected into one list to pack from
  • Stock put back when an order is refunded

11 integrations. Up to 8 shops on every plan. Nothing writes to a live shop until you switch it on.

Why this exists

A seller lists the same twelve t-shirts on Shopify, Etsy and eBay. All three think there are twelve. There are twelve. Then one sells on Etsy, and for as long as it takes somebody to notice, the other two are advertising something that is gone.

Most people solve this the same way. They keep a spreadsheet, they update it in the evening, and they hold a few back on every channel so the maths has room to be wrong. It works until it is busy, which is exactly when it matters. Then a marketplace cancels an order the seller cannot fill, and it is the account that takes the damage, not the spreadsheet.

That is not a discipline problem. That is a job software should be doing. So QuickSync takes the one number every channel is guessing at, keeps it in one place, and writes it back out to all of them.

What QuickSync does

One master stock count, copied to every shop you sell in. When something sells anywhere, every other channel comes down to match.

  • Stock, both directions, on all 11 integrations
  • Listings copied from one shop to the others
  • Orders collected into one list to pack from
  • Stock put back when an order is refunded or cancelled

Principles

What we stand for

Four rules we build by.

If it needs explaining, we got it wrong

Nobody bought inventory software because they wanted to learn inventory software. The setup should be short enough that you finish it in one sitting.

Fewer things, finished

We would rather do stock, listings and orders properly than ship a long feature list where half of it half-works.

Your stock is not a place to experiment

Nothing we build gets to edit a live shop until you have turned it on. Watch it for a few days first. Most people do, and we would.

Say what it does not do

Every channel has limits. You should know them before you pay, not after. We list every one.

Named limits

What we don't claim

Four limits we name up front. They are on the integration pages too, but they are easier to trust when they are not buried.

Not every channel updates instantly. Most shops tell us the second something changes. Etsy and eBay don’t offer that, so we go and look every couple of minutes instead, and Squarespace stock works the same way. Sending an update to a channel is quick everywhere. It is only finding out about a sale the channel made itself that can wait. Safety stock covers the gap.
Only six channels can take orders in. Shopify, WooCommerce, Square, Clover, Lightspeed and QuickBooks can be the shop you fill everything from. Amazon, Etsy, eBay, TikTok Shop and Squarespace hand their orders out to you, but they won’t accept somebody else’s.
Tracking doesn’t go back everywhere. We return tracking to Shopify, Etsy, eBay, WooCommerce, TikTok Shop and Squarespace. We can’t to Amazon, Square, Clover or QuickBooks, and on Lightspeed we can mark an order shipped but not carry the tracking number with it.
11 integrations today, no more and no fewer. All eleven are listed on the integrations page. If a page anywhere on this site counts higher, it is out of date: tell us and we will fix it.
Pricing

How we make money

A monthly subscription, and nothing else. We don’t take a cut of what you sell, we don’t charge per order, and a busy month costs the same as a quiet one. Plans start at $19 a month for two shops, with the tier set by how many items you keep. Every plan caps at eight connected shops.

The 14-day trial doesn’t ask for a card. If QuickSync isn’t right for you, you stop after two weeks having spent nothing.

Roadmap

Where we are going

Next: more channels — and fixing the gaps in the ones we have. The roadmap is shaped by support tickets, not brainstorms. The limits listed above are the gaps we most want to close: channels that can’t take orders in, and ones we can’t return tracking to.

Closing those gaps matters more to us than adding a twelfth logo to the grid. If there is a channel you need that isn’t here, tell us. That is how the list gets decided.

Try it on two shops first

You’ve been doing the spreadsheet. Two shops on the trial is enough to see whether you can stop. Connect two, leave it watching for a few days, and check the numbers agree before you let it change anything.
