This module allows you to synchronize orders between two Prestashop stores. Every time an order is done a request is send to the other site, which enables real-time synchronization. All the information that appeal to commands is synchronized (control messages, order details, taxes, delivery terms, ordering code, client, address, etc).
The module also enables real-time synchronization on stocks and order status, which allows you to send emails to the customer from the master store even if it is the second site that delivers, which is ideal for the dropshipping.
Both sites must be under Prestashop 1.4, 1.5, 1.6 or 1.7 (the version may be different) and it must be installed on both sites.
