Peter here from Shopify Support!
I'm not entirely sure whether adding Afterpay to our POS is on the roadmap yet, however, I can understand how this could greatly impact you and other merchants who have Afterpay available. I've gone ahead and created a feature request on your behalf to bring this to our products team attention. If the request is viable, and if Afterpay is able to handle this type of integration then our teams will do their best to get this launched in a future update. While these type of requests can take time to create, we will be sure to announce the feature if it becomes available in the future on our announcement page here.
Thank you for taking the time to let us know this is a wanted feature! We find this type of feedback extremely valuable as this helps us fine-tune what we work on to help our merchants grow.
Let me know if there's anything else I can help with!
Afterpay isn't yet supported within our POS as Shopify POS supports only Authorize.net & First Data Payeezy in terms of third-party payment processors. That said, Afterpay does appear to be available to store owners based in the United States, so customers based in the United States should be able to use this a payment method. For this, I'd recommend reaching out to Afterpay directly as they should be able to confirm this for you.
Let me know if you have any questions!
Thank you for sharing your feedback for getting Afterpay integrated into Shopify POS. Our teams review feedback daily so they can take the appropriate steps to determine if a feature is something we're able to add. At this time, the feature request is collecting feedback, but we do not have a timeline for when or if this would be added to our point of sale. I've added your vote to the feature request so our teams know there is continued interest in getting this added.
