We have a grace period of up to seven days after we receive the wire transfer or PayPal/credit card payment when invoicing.
Usually we upload the invoices every wednesday during the day.
Invoices will be uploaded to your PlayerPlus accounts via PDF only. You can find this under Settings and then click on the "Premium" button.
If you paid via Appstore, you will find the invoice in your respective account.
If you have any questions about invoicing in the app stores, please contact the respective support team of the store or have a look at the following FAQ entries.
