All Shutter+ purchases (subscriptions and lifetime licenses) are made through the App Store. Apple is the seller in these transactions. Apple processes the payment, collects any VAT or sales tax, and issues the receipt. For this reason, we cannot issue invoices or VAT receipts ourselves, and we cannot see your payment details.
You can get your receipt directly from Apple.
Apple emails a receipt to your Apple Account email address after each purchase and each subscription renewal. The receipt shows the date, the amount paid, and the tax that was included. To find it, search your inbox for “receipt from Apple” or “invoice from Apple”.
If you cannot find the email, view your purchase history:
For full instructions, see Apple’s guide: View your purchase history for the App Store and other Apple media services.
For questions about a charge, billing details, or the tax on your receipt, contact Apple Billing Support. Apple handles all payment questions for App Store purchases.
If you need to restore your purchase on a new device, see How to restore a purchase.
