These charges do not affect MRR. They only impact Net Revenue and Other Revenue.
If you are managing subscription charges manually, please note that this will not impact the subscription state or MRR. For example, if you stop sending charges, the subscription will stay active until you cancel it. This feature is purely designed to allow people to control the timing of charges, and for people who have custom proration methods.
If you want to manually manage subscription charges, then please contact support.
Otherwise, we will automatically create charges.
