Seller Labs does show some MFN-related fees, but they're limited because Amazon doesn't break them down as clearly as they do for FBA. Here's what you can expect to see for MFN (Merchant Fulfilled Network) orders in Seller Labs:
✅ MFN Fees You Can See in Seller Labs:
Referral Fee
The percentage Amazon takes from the item’s sale price (varies by category).
Shown as selling_fees in the sl_transactions_pivot table, regardless of fulfillment method.
Shipping Credit (what the buyer pays)
If you offer MFN shipping, the amount the buyer pays for shipping is visible.
Shown as shipping_revenue in the sl_transactions_pivot table.
Promotions/Discounts
If you’ve applied any Amazon promotions or coupons.
Shown as promotional_discount in the sl_transactions_pivot table
Sales Tax Collected
Shown if Amazon collects it on your behalf (not a fee, but visible). These are product_revenue_tax, shipping_revenue_tax, gift_wrap_revenue_tax, regulatory_fee_revenue_tax, promotional_discount_tax columns in the sl_transactions_pivot table.
How to get this data?
You can get this data using the AI Query Builder app (the instructions can be found on this link)!
Please select the sl_transactions_pivot table, then hit the Select All columns and run the query!
After it, please filter the results by Fulfillment Channel = MFN. See the video instructions below:
Alternatively, you are welcome to use SKU Details Slider for each SKU separately from the SKU Details app (more details on this app are on this link). Please check the video instructions on how to find the needed data:
❌ MFN Fees You Won’t See in Seller Labs:
Actual Shipping Cost (Freight)
What you pay to USPS, UPS, etc. — not tracked unless you're using Amazon Buy Shipping.
Buy Shipping Label Cost
Only available if you use Amazon Buy Shipping.
Restocking or Handling Fees
Not shown unless you manually track them.
Any External Platform or Carrier Fees
FedEx, UPS, Pirate Ship, etc. — those are outside Seller Labs' visibility.
To sum up, Seller Labs shows Amazon-assessed fees (like Referral and Promotions/Discounts fees), and buyer-paid shipping, but not your actual shipping costs or third-party fees. For true MFN profitability, you’d need to track those freight costs manually or integrate with a shipping/accounting tool.
