We have our Squarespace Commerce account linked to Stripe, and we primarily sell tickets to organization-sponsored events. We now want to be able to sell event tickets "at the door" to the event and take credit card payments with a mobile card reader, rather than force everyone to buy online while standing at the box office. Is there any way to use the Stripe e-reader with Squarespace and have sales integrated with Squarespace commerce reporting? Inventory management is not a concern but tracking all revenue in a single place is. Based on my reading, it appears that the only way to take in-person mobile payments is by using the Square card reader which uses Square as the payment gateway for in-person sales. This means I have two different processing accounts - one for online sales and one for in-person sales, which is inefficient, to say the least. Is there a better solution?
