If you choose Yes, you will receive an email on the last day of each month with our invoice for the 123Stat service. The invoice will be sent to the address you have entered under 'Contact email' in the Control Panel.
After sending the invoice we will attempt to charge your credit card (assuming that you are on a monthly payment plan of course). If for any reason the charge were to fail we will send you a second email warning you of that fact. You would then need to re-validate your credit card information from the Control Panel and we would attempt the charge again on the 20th of the following month.
