Advantages of self-fulfillment:
For some sellers, fulfilling European orders themselves may make sense, while some sellers use both FBA and the Merchant Fulfilled Network (MFN).
Some sellers use MFN so they can understand which products are selling well. This is a good option when delivery speed is not an issue.
Another advantage of sellers shipping directly to Europe is that they don't have to stock inventory in that country. In this case, there is no need to pay import VAT. (However, this can differ according the sales amount and conditions, so please consult an external tax advisor for details. Here is a list of service providers who can support VAT
When considering MFN, you also need to confirm the cost of international transport and the time it will take for delivery.
When considering MFN for shipment to Europe, you have to think about what local consumers expect. You need to provide accurate shipping times. You should also make sure to handle additional duties and taxes on your products in order to avoid exposing your customers to delays. This can impact your reviews and ratings.
