- * Depending on the plan configuration, any _flat_ recurring fees will be billed
- * either at the beginning (in-advance) or end (in-arrears) of each billing cycle.
- * Plans default to **in-advance billing**. Usage-based fees are billed in arrears
- * as usage is accumulated. In the normal course of events, you can expect an
