PastorsLine has two types of credits: non-rollover (NRO) and forever rollover (FRO). Basically, NRO credits expire at the end of the billing period and FRO credits never expire. We compare NRO credits to money in a checking account whereas FRO credits are like funds in your savings account. Read more about NRO and FRO credits in this article.
The situation here is that you would like to give FRO credits to your users. In other words, move credits out of 'savings'.
Why would you do that?
Perhaps you have finished the monthly / yearly credits which come with your plan (your credit 'checking' account). Maybe you want to assign more credits to your users than what is in your checking account. In either case, you want to use some of the credits in your credit 'savings' account.
What happens to those credits at the end of the billing cycle?
Once credits are taken out of savings for any reason, they follow the plan settings. If you are on an NRO plan, the credits will expire at the end of the billing cycle. If you have rollover protection, the credits go back into savings at the end of the billing cycle.
