You also have the option of setting specific deliveries for each order type in your delivery settings. To do this, go to "Parameters" > "Brand configuration" > "Delivery Settings", then use the scroll menu (see image below)
Example: do not authorize delivery to the customer for a customer order in a grouping order, since it is a grouped order to the seller (and therefore logically sent to the seller).
Without restriction, the activated delivery mode will be proposed for all order types. You can also set specific charges for each type of order for a delivery mode.
Example: set delivery to the seller as free if the order is in a grouped order, whereas delivery to the seller is charged if the customer order is not in a grouped order.
