💡 TL;DR

If you’re selling in multiple European Amazon marketplaces, SellerLegend lets you copy COGS values from one EU marketplace to the others. This saves time — but there are important limitations to keep in mind.

🔁 What Is COGS Propagation?

COGS Propagation means applying the same unit cost definition — including time periods and values — to multiple Amazon marketplaces within the European Union region.

This allows you to:

• Avoid re-entering the same costs multiple times

• Keep consistency across your EU listings

• Speed up initial setup

---

🗺️ Where Can You Use It?

Propagation is available only across EU marketplaces that use the Euro (€) , including:

🇩🇪 Germany
🇫🇷 France
🇮🇹 Italy
🇪🇸 Spain
🇳🇱 Netherlands
🇸🇪 Sweden
🇵🇱 Poland
🇧🇪 Belgium
🇦🇹 Austria
🇮🇪 Ireland
🇱🇺 Luxemburg

⚠️ Propagation does not work across regional groupings.
You cannot propagate from the EU to North America or Asia-Pacific.

🧭 How To Propagate COGS

There is currently no “auto-propagate” button or magic sync. But you can achieve propagation in two ways:

Method 1: Use Bulk Upload Template

1. Download the bulk upload template.

   • From the main menu, navigate to Products and Inventory > Products List.

1. • Click the Import/Export (top right corner, next to the Getting Started button).

   • In the Import/Export Panel, under the EXPORT section, choose the type of format you want to use

   • Click the EXPORT button.

   • An Excel file will be generated and downloaded, containing your current COGS data for the selected marketplace.

2. Fill it with COGS data for your source EU marketplace

3. Import the updated spreadsheet

   • Click the Import/Export (top right corner, next to the Getting Started button).
   • In the Import/Export Panel, under the IMPORT section, choose the type of format you want to use

• • Select the EU marketplace you want to import the update spreadsheet (Red bullet 2 in the image above)
  • The Import Panel will then show you which other marketplaces are compatible for propagation (Red bullet 3 in the image above)
  • Select the Excel file you want to upload (Red bullet 4 in the image above)

  • Click the IMPORT button (Red bullet 5 in the image above)

---

Method 2: Copy COGS Manually via UI

1. Go to Inventory > Products List.

2. Choose your source EU marketplace.

3. Open a product’s COGS editor.

4. Manually copy the values to the same product under the target EU marketplace.

   • You’ll need to do this per product.

🧾 What Gets Copied

---

💱 Currency Exchange Is NOT Applied Automatically

Even when copying between EU marketplaces:

• Currency values stay as-is — they are not converted.

• If you’re copying from Germany (EUR) to Sweden (SEK), you’ll need to adjust the exchange rate manually (in Detailed View).

🧠 Example:
If you paid €4.00 per unit in Germany and want to reflect that in SEK, you must enter the SEK equivalent in the target marketplace.

---

🔁 Can I Keep Costs Synced Over Time?

No. Propagation is a one-time copy, not a sync.

• If the source cost changes later, you’ll need to manually update the cost in the other marketplaces too.

• Consider keeping a master spreadsheet of costs to make bulk re-uploads easier.

---

🧠 Best Practices

• Use the Detailed View to retain currency, exchange, and vendor info when propagating.

• Adjust exchange rates manually per destination country.

• Re-propagate costs when you get new shipments or costs change.
