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.

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

You can download the invoice from your account on the Billdu website, navigate to Settings - Subscription - Orders and invoices. Every business of yours has its own invoice.

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