Products: Add unlimited products, variants and product collections. Products can be assigned to different locations (e.g. online, in store, warehouse) and tracked as you can see inventory statuses (e.g. received, transferred, order fulfilment).
Customers: Build relationships through customer profiles where transactions, notes, tags and contact details are saved. You can offer exclusive discounts, events and content through emails, if they have opted in for marketing emails.
Reports and analytics: There are more than a few reports to analyse sales, products sold, discounts given, cash flow, etc., but you only get a comprehensive daily sales report on Pro.
On Shopify POS Pro, you get a more sophisticated integration of online-offline features, for instance online ordering for in-store collection or delivery.
Pro also lets customers who bought something online return it in person, and the checkout gives personalised recommendations based on customers’ online purchases. You can also customise receipts and save carts to serve multiple people at once, and inventory and staff management are much more advanced on Pro.
