Currently, ecommerce is only in Italian.It is planned to create the dev environment identical copy of the live and there you will do the version update, as well as some changes to the display of the products but which are agreed with the customer.The ecommerce also sells on Amazon Marketplace via M2Pro module.The ecommerce receives requests for API calls from an external management system and therefore it will be necessary to check if all calls work regularly even with the new version.Finally, when everything is confirmed, the transition of the new updated ecommerce will be made with all the updated data so that no order and customer is lost.All project details will be provided to all those who accept NDA.The customer asks that at least the update and graphic theme part be done within 10-15 days.
