Hardware component to my Shopify App!

[TrinityS]

Hey team, 

We're developing an app for Shopify's app store, however we have a hardware aspect where customers will get shipped a device.

I'm just wondering if anyone has any experience with other apps that offer this aspect or anyone has any ideas on how best to handle that from a customer journey perspective while still making sure we operate within the parameter's of Shopify's Billing API rules? 

Thank you!
