Publish or link: which one do you need?

Both actions help you manage products across channels, but they solve two different situations:

• If a product exists on Channel A but not on Channel B → Publish it.
  Nembol creates a new listing on Channel B using the product information stored in Nembol.
• If the same product already exists on both Channel A and Channel B → Link them.
  Nembol recognizes that the listings represent the same product and connects them together, without creating a duplicate listing.

Publishing creates a new listing on a channel from the product content you have in Nembol. In the app it is the Publish to button in your Products tab.

Use it when:

• Your products are on one channel and you want to go multichannel.
• The channel you are publishing to does not carry those products yet.

What you need first: your products in Nembol, and the destination channel connected with its Publish settings configured.

Step by step: how to publish products with Nembol.

For Nembol to recognise two listings as the same item, they must match on all three points:

• SKU codes match. The same product must carry the same SKU code on every channel. If the SKU codes differ, Nembol cannot tell that the listings are the same item.
• Variations match. Products with variations need the same variation structure, and the same SKU code on each variation.
• Product structure matches. The hierarchy has to be identical — for example one parent product plus two variations on both channels.

If some products imported separately instead of linking, the Link function article explains how to fix them, and Catalog checkup finds products with duplicate, missing or inconsistent SKU codes.

The two are not alternatives you have to choose between once. A common path is to link what you already sell — connecting the listings on the channels you are on today — and then publish that same catalog onward to the new channels you want to expand to.
