Most people like the idea of eCommerce, but they do not know where to start. They think they need a big budget, a big audience, or a perfect product. They build a store too early, get no sales, and conclude that online business "does not work." In reality, they skipped the foundations: a clear offer, trust signals, simple operations, and a way to bring the right people to the store. The eCommerce Mastery is a practical guide wrapped in a story. It follows Panyim, a young Nuer writer in Juba, South Sudan, as he turns a dream into a digital storefront called PanyimTales.
