Multiorders has a dedicated tool that allows you to automatically merge inventory items based on a couple of different product specifications (as of 2021).

You can now merge products based on SKU, Barcode, Supplier SKU, Bin Location, Brand & Amazon ASIN codes.

Attention: make sure you have connected all of your sales channel integrations and their inventory has finished importing.

How to begin the automatic merging process:

To begin automatically merging your inventory, go to Tools -> Product Merge.

Once inside, the next step is to choose your first main integration.

Choosing the main integration means that all other sales channels would be merged to it. It also means that once the merging process is complete and you check your inventory inside the main inventory table, only the main integration product Title, SKU & Pictures will be visible.

When you click on the dropdown all currently available integrations will be displayed. Select the main one to which all other integrations will be merged.

Then choose the condition by which the other marketplace is going to be matched. You have a few different options. In this case, we will choose SKU.

Then repeat the process and choose your child integration. This integration is going to merge to the main integration.

Here you choose the condition of the child integration. We will choose SKU as well. We normally recommend having identical SKUs between sales channels, but if that is not possible, we have included additional merge options like Barcode or Brand. While the fields can be different, their actual values must be identical. For example, if you have a product on Etsy with SKU "123456" and want to merge a product from Shopify by Barcode, the barcode for the Shopify product should also say "123456".

All that's left is to press the green button on the right called "Merge".

Once you press Merge, the app will throw one last warning about the process

Press continue and a status update will be set on top of the window saying that you now need to wait for the merging process to complete.

While it's merging the app will look at the available Shopify products, look at their SKU and then try to find an identical SKU amongst the Etsy store products. If found the products will be merged together.


Keep in mind that if you have multiple products in the child shop, with the same SKU, those products will merge together into one item. This can be of value when you have duplicate listings on the same store.

Refresh your window to see if the merge process has completed. If yes, then you will see a new area of "Current Merges" appear.

Also, at the bottom of the page, you will see your merge history. There you can see what actions you have taken and what is their current status.

If you click in the ‘Details’ column, you can see how many items were affected by the merge.

Adding additional integrations to the same merge is really simple. Look at the Current Merges area, then closer to the child integrations section.

If you want to add another integration to the same merge, you now need to select it from the dropdown.

Then select the condition by which we are merging.

Finally, press the "+ Merge" button below it. Once the process is complete you will see the new integration added. This process can be repeated until you have all of your integrations connected.

Please Note: You can have multiple groups of merged integrations with a dedicated main integration. Simply repeat the steps from the beginning, simply choose different integrations. All integrations that have already been merged, will simply not appear in the list.

Important: All product information is transferred from the main product to all child products. This means that if your main product did not have, for example, a Supplier SKU which you used to match the child product to the main product, it will be removed from the child product after merging. This means that you will not be able to merge the products again after unmerging.

In order to avoid this, you should always update your products with the same information. Field updates such as Barcodes, Supplier SKUs, etc. will not affect your actual shop.

Merging leftover products:

During the steps earlier, we merged Shopify & eBay to Etsy. Now Shopify and eBay are in the same merge group, but they do not communicate with each other, each integration is looking to merge to something on Etsy.

In certain situations, you may have products that have identical SKU (or other identifiers) in between child integrations, like Shopify and eBay in this situation. To combat this there is an additional merging step that can be taken, called "Find and merge loose products in between your child integrations". You can find it right under your merged child integrations.

After you have completed the main merging process, you can try and merge loose products between the two sales channels. The process is practically identical to the main process.

Choose your integrations and choose the data by which you are trying to match them

Then simply press "+ Merge" below the selections. Once the process is complete you will get an additional merge combination.

This should be used as a last resort when matching products is impossible during the main merge process. As we will mention later in the guide, this version of merge cannot automatically check for new products to merge during import and you would need to press "Find New Products" manually every time a new product is imported from either child integration.


Enabling automatic product merge during new product import:

After a while, you may get new products that appear in your inventory for both your main store and your child integrations. This can be checked automatically and manually.

To manually check if there are any new products to be merged, click on the "Find New Products" button.

Pressing that will restart the same process that happened initially and the system will then try and find any new products that can be merged.

Please be aware: For the merge to work, the main integration must have the product first, if only the child integrations have matching products, they will not be merged.

To automatically check for new products, look at the "Find New Products" button mentioned earlier, you will find an empty checkbox near it. Hover over it for extra information and press on it.

Once that feature is enabled, whenever a product is imported into Multiorders, we will check and try to see if it can be merged to anything.

But as mentioned earlier, the main integration must already have the product imported into Multiorders or the merge will fail.

Please Note: Automatic product search does not work for secondary merges created between child integrations. And you will need to press "Find New Products" manually if you expect more products to be found.

Unmerging integrations:

Before you delete the integration from Multiorders it must be unmerged first. You can unmerge integrations from the same place you merged them. Just click the ‘Unmerge’ button next to the store you want to remove from the current merge.

A notification will pop-up asking you to confirm this action.

If you have any child integrations merged together, you will need to unmerge those first, otherwise, you will get an error message.

Please be aware: that if the inventory item has any item in-order, the order will be connected to its initial marketplace product and the unmerged products could unmerge with a larger quantity.

Important things to keep in mind

Pay close attention when you want to merge integrations that you have added some time ago. If an item has an order assigned to it, the ordered products will carry over to the entire merged group and reduce stock from the main marketplace. If, for example, you have an item that has 2 in-order and you merge it to a group that has 1 item available, the entire group will go down to -1.

When merging the main integrations product data becomes main inside the multiorders inventory, which means that data inserted manually like weight, barcode, etc. may be overwritten on child integrations by the main one. This affects only the data on multiorders and not on your sales channel.

As mentioned earlier, for the automatic merge to work, all products must be present in the main integration. To make sure the latest products have imported, please go into Settings -> Integrations, find your main integration, and then check the bottom right corner for green arrows.

If you hover over them it will say "Schedule full sync". If you press this button, Multiorders will import the latest available information from your sales channel.
