I started a shopify trial and had data in the system from a previous import. I contacted shopify about deleting everything and they cannot do it. I cannot work with the orders and customer data in the store. they were not orders placed in shopify they were placed in a previous system.
Hi, @tommcmur
You can follow these steps here to cancel your account.
With that said though, once your import has been completed, you can delete orders and customers.
Let me know if this works as a solution for you!
