Transitioning to Amazon's intricate ecosystem can pose a significant challenge for brands that have already solidified their presence across Europe, particularly through traditional offline distribution channels. This challenge is exacerbated by the fierce competition that pervades Amazon's product marketplace. It becomes even more pronounced, especially in the case of technically sophisticated products where suppliers are accustomed to dealing with higher volume distribution. Consequently, this shift may lead to sales fluctuations when third-party sellers opt to introduce the same products in smaller, more consumer-friendly quantities.
