Where Stan Store wins, clearly
Selling digital products. Checkout, delivery and the customer relationship are the product, not an add-on.
Bioflow has no store and does not process payments for your products. If that is your business model, this is not a close comparison.
Where Bioflow fits instead
A business whose revenue happens in person — a café, a barbershop, a studio — where the job is bringing someone back next week rather than closing a digital sale today.
That is what the loyalty program is for, and Stan Store has no equivalent.
