Bill Now and Redeem
Use this option when patients need their meds in advance of their next scheduled billing date.
This will charge the patient and push an order onto your Pending Pharmacy Orders Page for review. This option will leave their existing billing schedule intact, it changes the next bill date to what it would be if they had waited to be charged.
Change Payment Date
Use this option to move up a bill date 2 weeks or postpone a bill date 4 weeks.
This option is only available if they are within one billing period of their next bill date, and can only be advanced up to one billing period. If it is a 28 day subscription, their next payment must be less than 28 days away to use this option.
This feature is not intended for long delays, if the patient needs a longer delay it will be best to cancel their subscription and reenroll when they are ready to start up again.
