Customer plans can change during an active billing period. The difficult part is making sure usage from before and after the change is connected to the correct plan.
How should a billing system decide which plan applies when a customer uses services during a period where two plans are active?
Multiple Active Plans
A customer may have more than one service or may temporarily move between plans. The billing system needs to understand which plan applies to each type of usage.Plan Migration
When a customer moves from one plan to another, the old plan should not continue charging usage that belongs to the new plan.Effective Dates
The exact date and time of a plan change can be important. Usage before the change may follow the old pricing, while usage after the change may follow the new rules.Usage Allocation
Billing systems need to separate usage correctly when different pricing rules apply within the same billing period.Invoice Accuracy
If usage is assigned to the wrong plan, the final invoice can be incorrect even when the individual CDRs are technically valid.How should a billing system decide which plan applies when a customer uses services during a period where two plans are active?
