# General Pricing Rules

## Pricing Model

The specific pricing model is subject to the regulations of services. Generally two kinds of pricing models are supported in zenConsole: [**Subscription**](/welcome/pricing/general-pricing-rules/subscription.md) and [**Pay-as-you-go**](/welcome/pricing/general-pricing-rules/pay-as-you-go.md).

## Billing Start Time

Billing starts when a resource is **created successfully and becomes available**:

* **Compute instances** (elastic compute, virtual machine, bare metal, and GPU cloud): billing starts when the instance is created successfully and its status becomes **Running**.
* **Associated resources** (elastic IP, disk, snapshot, load balancer, NAT gateway, and so on): billing starts when the resource is created successfully and becomes available.

You are not billed when you place or pay for an order, or while a resource stays in the **Creating** status.

The temporary hold verifies your account balance. It is not a charge, and a frozen temporary hold does not mean that billing has started.</mark>
* <mark style="color:blue;">If a resource fails to be created, you are not charged: fees paid for subscription resources are returned, and the temporary hold for pay-as-you-go resources is unfrozen and returned to your account balance.
