is it possible to import orders and auto create a new customer if necessary? for example if I have a csv of customer info + order lines, can I import it all in one hit? create the customers (if necessary) and order at the same time

In my mind I think it’s a two stage scripted import. You could put your file to a folder in the cabinet then use a script to first import and create the customer records, then use the same file to create the orders.

Celigo integrator.io could probably do this.
