Gaito Wholesale Store runs on the latest version of PrestaShop, comes in multiple language versions, and has an implemented module for verification of registered customers and operates as a dropshipping platform. Our work on the current version of the store mainly concerned the graphic design, both for browsers running on PCs and the RWD version prepared for mobile devices: smartphones and tablets, which are often used to make purchases at the wholesaler. During the work, a number of sub-pages were redesigned, which we adjusted visually and functionally to meet the expectations of modern B2B customers. The current version of the Gatito Wholesale store is already its 3rd installment prepared by our team, so we can say that we have been working with this client for several years.
