How Bank Transfers Work:
If a Customer chooses bank transfer as a payment option, they will receive an email with the information they need to make the transfer. You then will need to watch your bank account for the money. When the money arrives, manually move the order from Awaiting Payment to Payment Received status on the Orders page in your admin.
