Can We Use Square?
We can only integrate payment processing with Stripe.com or Authorize.Net, see Credit Cards for more details on this. Although if you are taking payments at checkout, you can use a Square reader alongside Auctria but it would not be integrated.
You would need to process the payment in the Square app and then record it in Auctria. This would be done as if the bidder was paying by cash or check. See Checkout Payment Options for more information.
Please note, this will not allow bidders to pay online themselves. In the case of Tickets, the only options there would be: using a Stripe/Authorize.Net account; or, enabling the 'allow pay later' button.
This would allow bidders to purchase tickets without making a payment and then settle up later.
