I am looking to build a ecommerce site for a client using shopify headless with storefront built in Next.Js.
As part of the requirement, we want to be able to allow customers to create and manage their account - order details and their measurement information.
I cannot find a clear documentation as to what shopify plan I need to be on and if feature like Customer Account Creation is easily done? Do i need to be on a shopify plus plan? If so, that is expensive.
If I build my own user authentication and authorisation flow, how would that work with completing the order and associating it to a logged in customer?
