Flat-Fee Billing Model

The Flat-Fee billing model implies that a fixed fee is paid monthly by a customer for the service, regardless of the actual resource usage.

In the Flat-Fee model, there are several service plans, and each plan represents a different configuration of VPS.

When you buy a VPS, you pay a fixed price set by the provider for this specific virtual server hardware configuration.

Configuring the Flat-Fee model includes:

Creation of a VPS Hosting service plan, based on a VPS Hosting service template.
Configuration of a Virtual Private Server purchase scenario.
