Have you ever encountered situation that even though your client provided a valid credit card details his/her recurring payments aren't charged automatically by HostBill? If such situation is known to you, it seems that firstly you need to check:

• If you enabled ‘Charge Credit Cards’ task under General settings -> Task List (it will only work with properly configured Cron)
• If you activated any Credit card module under Settings -> Modules -> Payment Modules (such as Authorize.net CC, Cybersource, Dibs, etc.)
• If client’s credit card is still valid (expiration date can be now easily controlled with HostBill new plugin - CC Expiration Notify)

How credit cards are saved in HostBill:

• HostBill saves credit card details only when clients use credit card module for payments (during the order)
• HostBill DOES NOT save CVV/CV2/Security code. Client is asked about it ONLY once at the checkout stage. Note: Those codes’ storing remains forbidden and illegal.
• HostBill saves credit card details in db once the first credit card payment has been performed.
• Clients can delete their credit card form their profiles anytime (on the condition you (Admin) disable such possibility under General Settings -> Billing -> Credit cards -> Allow to remove CC)
• Credit card number and expiry date is saved in db as an encrypted data.
