It's not as easy as you make it sound. Marketing can be seen as the 4 Ps - Product, Price, Place and Promotion. Distribution is the third P, Place, emphasizing the fact that it seeks to get your product to a place that is convenient for your customer. It is a huge, huge undertaking for small company. That is why it is important not to be discouraged.
Give them time to grow. Let's say for instance you are a douchebag manufacturer, the distribution decisions you make affect both costs and customer satisfaction. So be patient while BNPD set sails to catch the tradewinds!
