Ok, so given this unpleasant reality -- here's a somewhat different challenge: How do you suggest combining the customer data collected via Square (in person, art show sales for example) with the customer data collected via Squarespace (online sales, website forms)?
I presently use the email tools in Squarespace to communicate with customers about upcoming shows, online sales, etc. so I find myself manually importing the Square .CSV files with email addresses after every show. That would be only inconvenient **IF** the result in Squarespace also captured the customer's transaction history, POS spend, items purchased, etc., but it does not. Switching to Square for my email communications seems not ideal as their marketing tools are not as advanced, but am I better off using that? Either way, it seems I am losing cumulative customer purchase data between systems.
Personally I'm less concerned about inventory mgmt as all my work is OOAK, but I certainly am interested in being able to track my great customers -- no matter what platform they purchase on, or when.
