Shopify - Customers

The Customer on each order is matched by email address to the existing Customers in the point of sale. If applicable, their shipping and billing address information in the point of sale is updated with the shipping and billing information on the Shopify Order. This allows you to keep a complete customer purchase history within the point of sale.
 

NOTE: If a Customer uses a different email address for their Shopify account than the email address in point of sale, a new Customer card will be created when the order is downloaded.

NOTE: If multiple Customers use the same email address in POS or Shopify then matching inconsistencies will occur.
