Currently, our billing system (which is based on Stripe) only supports credit cards as payment method.
The supported card types are Visa, MasterCard and American Express.
We hope to be able to add additional payment options in the future as Stripe adds support for them.
Unfortunately, since we're using Stripe, you can't use PayPal or bank transfers to pay your invoices. We rely on automated processing of all invoices to keep our fees and prices low.
If you have any questions about billing or licensing, please contact us via the website chat or by email at support@soundflow.org
