I am currently trying to test out my business model by estimating my potential margin and annuals sales. My current method is to manually scour dropshipping/wholesale platforms for a product that fits my model and then finds its selling price on a set of online stores (bottom price (amazon), medium brand, luxury brand). My challenges are: finding brands that fit with my business model (high quality stem toys built in developed countries) efficiently searching dropshipping/wholesale platforms I have been researching product tools but find most focus on trendy “winning products” What is an efficient method to determine costs of goods, sale price and the number of sales possible? Are there any services or tools that you would recommend for this purpose?
