When designing the store for the eCarla Wholesaler, we made sure that B2B customers could conveniently browse the wholesaler's assortment, so we prepared the graphic design along with the RWD version for mobile devices in accordance with the assumption of the best possible display of products. After migrating the store from another sales platform to PrestaShop version 1.7, we ensured proper optimization, as speed was crucial in this case, and also developed different language versions of the store, for sales to foreign markets. We also implemented features dedicated to B2B sales, such as excluded prices and a verification system for registered customers. One of the most important features of the bottom of the eCarla Wholesale Store was the implementation of a dropshipping module: our client's partners can get access to a convenient dropshipping panel, through which orders are placed, which are then directly sent to end customers.
