Overview

CFW supports the yearly/monthly billing mode.

Yearly/Monthly billing is a prepaid mode in which you pay for the service before using it. Your bill is settled based on the required period. The longer the subscription term, the bigger the discount. Yearly/Monthly billing is a good option for long-term, stable services.
