Docsico

Selling on Amazon offers multiple fulfillment options, but choosing between Fulfillment by Amazon (FBA) and Self-Fulfillment (FBM - Fulfillment by Merchant) can significantly impact your profitability. In this guide, weβll compare both models based on costs, scalability, convenience, and profit margins to help you make an informed decision.
