How phones are bought
Phone buyers know exactly which model they want and compare price across every seller, which means margin is thin and differentiation has to come from elsewhere: whether it is actually in stock, what the old phone is worth, and what the warranty covers if something fails. Grey imports make warranty a genuine concern, and a shop that does not state its terms is assumed to be selling unsupported stock.
What we build for a phone store
First, accurate stock per branch with specifications and comparison, since the customer has already chosen and needs to know where it is. Second, trade-in valuation built into the product page, because the old phone funds most of this market. Third, warranty and service terms stated explicitly, which is how an official seller distinguishes itself from grey import competition. Fourth, accessories attached to the model, the margin this category actually runs on.
