Overview

There are yearly/monthly and pay-per-use billing modes to meet your requirements.

Yearly/Monthly billing is a prepaid mode in which you pay for the service before using it. Your bill is generated based on the required duration you specify in the order. The longer the subscription term, the higher the discount. This mode is generally suitable for mature businesses with long-term stable equipment needs.
Pay-per-use is a postpaid billing mode. You pay as you go and just pay for what you use. This allows you to adjust resource usage easily.

Table 1 compares the two billing modes.
