Hosts can receive money directly on their bank account (via bank transfer) and then allocate those funds to a given project via the dashboard.
Financial Contributors are able to choose 'Bank Transfer' as a payment method:
The instructions for the wire transfer are sent to them via email with a unique transaction identifier. Once the money has been received in the Host's bank account, and admin of the Host will be able to mark the transaction as received in the Host Dashboard and the funds will be added to the project's budget.
To set up this option, please go to the host's profile settings in the Payment Methods tab.
