If you've bought a subscription in a mobile app, you'll receive an invoice either from Apple App Store or from Google Play Store.

Take a look at your Apple / Google account or contact the respective support to receive an invoice.

For a Google Play invoice click here.

For information on Apple invoices click here.

Only if you've bought a subscription directly from Billdu (on our website, via an email or discount link), then an invoice will be sent to your email automatically after the payment.

You can download our invoice on the Billdu website, navigate to Settings - Subscription - Orders and invoices.

In some cases we charge tax, take a look here.
