A modern B2C platform created based on PHP technology

The platform architecture assumed the launch of a central management area (Backoffice) with information on inventory (Warehouse States Server), prices (Price Server) and data on inventory (PIM).

The sales platform was integrated with the customer’s existing ERP (SAP) system, which was done using the ESB Data Bus – an open source solution enabling flexible and scalable linking of applications and, above all, the flow of data between them in real time. This is particularly important when it comes to the flow of information about products and orders, as well as on-time inventory updates.
