Chargebee Help Center

This feature will allow merchants to offer their buyers an alternate way of making payments. So buyers will be able to pay by check, pay at the door, cash payment or request to send an invoice. When the buyer chooses an offline payment method and signs up, a new subscription will be created in ChargeBee with the invoice status as "Pending". Upon receiving the payment, merchants can mark the invoice as "Paid".

If you have any questions or ideas you would like to share about this upcoming feature, please do post them here.

ETA:  1st Week of April 2013
