When creating an order in Akti, you can enter the expected delivery date for the order after selecting the customer account. This delivery date is by default set to the same date the order was created.
You can enter a default delivery term via the settings, ensuring that this date is by default X number of days after the creation date. To do this, go to the Sales Order Settings, click on Basic Settings and then Default settings. Here you can enter the default delivery term (in days) at the bottom of the page.
