Marketplaces
Connect each shop once, in a few minutes. Then every listing goes to all of them in a press, and the stock stays in step everywhere.
Make the listing as usual and publish it to eBay.
Under it, Also list it everywhere else you sell shows every marketplace you have connected.
The title, description, photos, price, stock and item specifics go across. Nothing to type again.
Stock is kept in step: every five minutes each marketplace is checked, and a sale on one takes the quantity down on all the others. See and change it in Settings, under Stock.

In Flash Listings, go to My profile, then Marketplaces, and find Amazon.
Pick your Amazon marketplace - Amazon.co.uk, Amazon.de, Amazon.com and the rest. Connect takes you to that country's own Seller Central.
You are taken to Amazon. Sign in to Seller Central as usual - Flash Listings never sees your password.
Amazon shows what Flash Listings may do for your account. Press Confirm, and you are brought back here.
Your store now shows in the shop picker at the top, with its name and an Amazon badge. Choose it to list, edit, see your Amazon sales and more. You can disconnect at any time from the same place.
One Amazon account covers a region - Europe (with the UK), the Americas, or Japan, Australia and Singapore. In Marketplaces, under Amazon, choose Sell on to switch to another marketplace in your region, such as Amazon.de beside Amazon.co.uk - no new sign-in. Your listings already on the first keep their stock in step.
Sign in with the account that owns the business - its main login, not a user added to it - and make sure it is on the Professional selling plan.
Add the product's EAN to the listing. If your products have no barcode (your own brand, handmade), apply for a GTIN exemption in Seller Central.
Amazon wants something the listing did not say. Fill it in Amazon's details on the listing form and try again. Some categories also need Amazon's approval before you can sell in them.
