One owner
for each kind of data.

Two systems that both think they own your stock will overwrite each other. So you choose an owner for each kind of data, and the hub follows that owner instead of fighting it.

  • Four kinds of data: catalogue, price, stock and orders
  • Owner can be the hub, Shopify, Etsy, a file feed or your own system
  • A preview shows what stops and what starts before you switch
  • Your own changes still go through — with a warning

Who can own what

Each kind of data has its own owner. The same store can own your stock and not your prices.

Catalogue

Titles, descriptions, photos and attributes. Usually the place you import from. If you import from two places, the page says there is no single owner — it does not guess.

Price

The hub, Shopify, Etsy, a file feed or your own system. Amazon and eBay cannot own price, because they give us no way to follow price changes.

Stock

The same choices as price. Shopify tells us about a change at once; Etsy is checked every 10 minutes when things change, and less often when they do not.

Orders

Who ships, cancels and refunds: the hub, or your own warehouse system through our API. Orders always come in from the marketplace.

How the hub follows the owner

Clear rules, so a change never goes round in a circle and the wrong system never wins.

Owner in, channels out

A change from the owner is matched by SKU and sent to your other channels. It is not sent back to the store it came from.

Non-owners stay quiet

A store that no longer owns stock stops writing stock. It can still own price — each kind of data is checked on its own.

Your change, with a warning

If you change a price the hub does not own, the change goes through, and we tell you the owner's next update will replace it.

Switching owner, safely

The switch is a short wizard, and it shows you what will happen before anything changes.

A preview first

The preview names the syncs that will stop and the ones that will start, so nothing is a surprise.

Enough prices to switch

Moving price to the hub needs a price on at least 90% of your products. The wizard can fill the empty ones from your channels.

Never a zero price

A product with no price anywhere is never sent as 0.00. A missing price is a problem to fix, not a number to publish.

Frequently Asked Questions

What happens by default, and what changes when you choose an owner.

Still wondering?

Our team replies within a few hours, Mon–Fri.

01 Do I have to set this up?
No. If you choose nothing, the hub works out the owner from your setup: a store with stock sync turned on owns stock, and with nothing syncing the hub owns it. The Data Flow page shows if an owner was chosen by you or worked out by the hub.
02 Why can't Amazon or eBay own my price or stock?
Neither gives us a way to follow price and stock changes made there. They can still be the place you import your catalogue from, and they always get your price and stock from the owner.
03 Can a marketplace own my orders?
No. Orders always arrive from the marketplace, but shipping, cancelling and refunding are done from the hub or from your own system through our API. An order the marketplace fulfils itself, like Amazon FBA, cannot be shipped from the hub.
04 What happens if I disconnect the store that owns my stock?
Ownership goes back to the hub, and the stock sync from that store stops. Your channels keep the last numbers until the hub or a new owner changes them.
05 Where do I see all this?
On the Data Flow page in your account. Each connection shows which kinds of data it owns and which way the data moves. The dashboard shows the same owners as small chips.
