For an In-App Purchase made by a customer whose App Store account is in the Saudi Arabia storefront, where Apple acts as commissionaire and remits VAT, does Apple issue the customer any tax document (a VAT invoice or a tax receipt), or is the customer's purchase history the only record available?
Apple's support article 'View your purchase history for the App Store and other Apple media services' (support.apple.com/en-us/118212) documents viewing purchase history only — the words 'receipt', 'invoice' and 'tax' do not appear on that page.
