Can I get an invoice for my subscription?

Yes, but how you receive it depends on how you signed up.

Apple Subscriptions

Apple handles all billing and receipts directly. You can find your purchase history by going to Settings → Apple ID → Subscriptions on your device, or visit reportaproblem.apple.com to view and download receipts.

Glass Subscriptions

You’ll automatically receive an invoice by email each time your subscription renews. It comes from invoice+statements@glass.photo, so be sure to check your spam folder just in case.

Not sure how you signed up? You can check your subscription type in Membership Settings.
