Because your start-up capital is low, one of the problems you face is small purchase volume, high purchase cost, and low profit. It is possible that you have been busy for a long time and thought you made some money, but it is very likely that it was in vain. The most important preparations to do are 1. Understand

The current market situation in the region (products, pricing) 2. Calculate whether there is any profit from this based on your actual operations 3. Also consider how to deal with competitors who will join once the business is good. Good luck.
