It is cool for all sizes of business, however, there is one significant concern from the payment perspective - Shopify creates a big challenge for the alternative payment methods to be listed in the Payment methods` list. The requirements for P-methods in order to open Shopify API for integration is quite too much, really to much.
So if I have a local method that is not well-known in the world or does not process 10millions everyday - it is almost impossible to add it to my shop.
Hope that Shopify team can review their strategy in this aspect as the rest tools and services are amazing.
Looking for some updates.
